Section one wax connector with a thin ribbon saw (sewing thread is a suitable alternative) and remove the isolated retainer from the master cast. – Recontouring and ridge augmentation in case of large ridge defects. Then wax the pontic to proper axial and occlusal (or incisal) contour (Fig. Porcelain is supported by metal placed at right angle to the occlusal force. Pontic serves to restore the mastication, speech to maintain tooth relationships, both interarch and intra arch, and also to satisfy patients esthetic and psychological needs by eliminating the space in dentition. Reseat the first retainer, reattach it to the pontic, section the other connector, and repeat the process. Minor retainers do not need full occlusal protection: a minor retainer may be a partial crown or a two – or three-surface inlay without full occlusal protection. He justified that, the esthetics will not be compromised as in 90% of the cases, the mandibular cervical region is not visible. The hygienic pontic is the least “toothlike” design and is therefore reserved for teeth seldom displayed during function (i.e., the mandibular molars). 1 Connectors, the portion of a fixed dental prosthesis that unites the retainer(s) and pontic are concentrated on them . Changes in residual ridge, opposing occlusion and proximal space affect the success of the restoration. A correctly designed posterior pontic should have the following characteristics. Metal-ceramic pontics are stiffer and withstand occlusal forces better if they are made fairly thick and if the porcelain is carried right round them from the occlusal to the ridge surface leaving only a line of metal visible on the lingual surface or none at all. for example a complete gold crown retainer with a metal-ceramic pontic. Contacts with the ridge extends beyond midline. They are supplied with an uncontoured porcelain gingival surface and usually with two retentive forms on lingual side. Pontic may be connected to a retainer through a rigid connector such as a cast joint or soldered joint or a non-rigid connector such as key and keyway or as in telescopic retainer. – If space between gingival surface of pontic and ridge is less may lead to tissue proliferation. Change ), You are commenting using your Facebook account. The interpontic embrasure in filled in anterior segment using pink porcelain which also solves the esthetic problem and in cases of moderate ridge resorption and loss of papillae between pontic and abutment. They have a wider scope and most commonly used and widely accepted. Restores function and stabilizes adjacent with opposing teeth. only to manage excessive (single/multiple) pontic space(s), but also to splint pathologically migrated teeth effectively.3 Loop connector is a non-rigid connector and consists of a loop on the lingual aspect of the prosthesis that connects adjacent retainers and/or pontic.9 The loop may It cannot be used when there is reduced interocclusal distance due to the presence of a large gingival bulk. Such cases can be treated by two methods: One is to modify the pontic and fill the entire embrasure space with pink porcelain. It should be made as convex as possible, with only one point of contact at the center of the residual ridge. Gingival surface is shaped like arch may mesiodistally. Its convex tissue surface resides in a soft tissue depression or hollow in the residual ridge. Cast connectors are stronger than soldered connectors. It should be positioned over the backing such that the gold porcelain junction does not contact the tissues. and should not contain any junctions between different materials. In these types of bridges, the abutment teeth require preparation and reduction to support the prosthesis. The design is based on the aesthetic, functional and hygienic requirements. Cases with severe residual alveolar ridge resorption should be treated with ridge augmentation, tissue grafts, etc. According to Eissmann (1971) The boundaries of edentulous space are residual ridge opposing occlusal surface, proximal surface of abutment teeth and musculature of tongue and cheek or lips. Pontic facing was made of porcelain denture teeth multiple drill holes of 2mm deep were made using frill press on the lingual surface of the facing. SELECTION CRITERIA FOR PONTIC AND PONTIC DESIGNS. Lingual contour should be in harmony with that of the adjacent teeth. – When PFM retainers are used PFM pontics are selected. Occlusal gingival height and mesio distal width of edentulous area. Loop or a spring type Design considerations for a posterior pontic. They resemble sanitary facings but they have positive pinpoint tissue contact. complete denture an appliance replacing all the teeth of one jaw, as well as associated structures of the jaw. Â Â Tissue contact is very important for a pontic. Place a post into the hole and should be seated snugly in the shaft to ensure there is no movement towards the ridge. Kindly find the references stated at the end of each blog. Fabrication of a small anterior pontic gives an ugly appearance. Possess all or nearly all convex surface. rigidly fixed to the retainer provides adequate strength and . Amazon.com: electrical cord retainer.  An FPD with the pontic . In the maxillary teeth the buccal cusps provide aesthetics. The pontic should not be designed to pressurize the alveolar mucosa, as it may ulcerate. Replacement of missing permanent teeth in which the Retainer/Abutment teeth have a favorable long term ... Connector Bar Connector Bars may be indicated to brace individual Retainer/Abutment teeth with considerable coronal ... D6243 Pontic – porcelain fused to titanium and titanium alloys D6245 Pontic – porcelain/ceramic Causes tissue inflammation and hence not used. An innovative revolutionary Inzoma pontic. The primary purpose of the dental bridge is to receive the forces of occlusion and to transmit them through the abutments so that occlusion is … The result after 6 months of observation showed that. The pins in the porcelain tooth are ground off and the tooth is altered and customized according to the ridge. (The pins in the backing are fabricated according to the facing and not the vice versa). The components of a bridge are retainers, pontics and connectors. It is used in the form of key (tenon) attached to pontic and keyway (mortise) placed within the retainer. 28-8 In the presence of a diastema that is to be maintained, a loop connector may be indicated. Hygiene maintenance (flossing) is more important than the pontic design itself. The connecting link between the major connector or base of partial removable dental prosthesis and other components of the prosthesis, such as the clasp assembly, indirect retainers, occlusal rests, or cingulum rests. Smaller pontic will compromise esthetics and hygiene. This slot and the proximal bevels provide retention. Amount of Occlusal load that is anticipated for that patient. The contour of the residual alveolar ridge. Study by Reichenbach E 1931 stated that it was used to prevent the extraction site from collapsing after removal of a tooth and to imitate the natural emergence profile of the tooth. For two things to be joined together there should be a medium for it. These facings are used when the tissue contact of the pontic should of glazed porcelain. 6. This means that they must be smooth and highly polished or glazed. If it is placed more anteriorly, food accumulation may occur, The pontic should have minimal facial contact to obtain good tissue response. In such cases, a proper pontic cannot be placed and the design of the pontic should be compromised. The lingual surface should be designed such that it is similar to adjacent teeth from the cusp tip till the height of contour, then it should recede sharply and concavely from the height of contour towards the facial surface to form a pinpoint contact on the labial surface of the residual alveolar ridge. Complete the retainers and contour the proximal and tissue surfaces of the pontic for the desired tissue contact. Castings are done in usual manner the pontics are either cast connected or soldered. The only disadvantage of this design is its poor aesthetics, which results due to wide embrasures. – Blocks self-cleansing mechanism of tongue and cheeks. This means that the groove or depression in the minor retainer (the female part of the attachment) always have a good base against which the male part of the attachment can seat. Conventional bridges are bridges that are supported by full coverage crowns, three-quarter crowns, post-retained crowns, onlays and inlays on the abutment teeth. It is indicated in cases with reduced occluso-gingival height. $63.52 $ 63. In such cases, abutment teeth are repositioned orthodontically or modification of abutment teeth with complete coverage retainers are done. The pontic on an implant supported bridge is reported using the conventional pontic code representing the material used (e.g., D6245 for a porcelain/ceramic pontic). 2.Buccal and lingual surface follow a normal tooth form from cusp tip to height of contour and tapers from here to gingival surface. 4.0 out of 5 stars 25. 5. 7). Pin pontic modification of long pin pontic, is intend to grind the tissue surface for appropriate contact and then polished or glazed. Roughness of pontic material and dental plaque â JPD 1990 (23) 407-411. The pontic replaces the missing tooth. It is indicated for the replacement of mandibular posterior teeth where aesthetics is not a major concern. It is important that the embrasure space between the connector and the gingival tissue be as open as possible to ensure that there is good access for cleaning. This pontic is very easy to clean and maintain. 2. Class I : Loss of faciolingual ridge width,with normal apricocoronal height. Tripodakis A P 1990 : Contour of alveolar ridge requires a convex basal seat in the design of pontic to prevent the impairment of esthetics , function , phonetics. The buccal and lingual surfaces of a pontic will be designed as a result of deciding the ridge surface. All the functions should be executed in a manner compatible with oral health and comfort. Change ), Fixed Prosthodontics – Components of the Dental Bridge. Other disadvantages include the need for surgical tissue management and the associated cost. Modified ridge lap pontics where tissue contact is strictly limited to the labial surface of the ridge. – Can not be used of occlusogingival space is very less. Bodirsky H 1992, Spear F M 1999 also stated that immediate pontic technique can be used as a modified application, to maintain the topography of alveolar ridge after the extraction of the tooth. A three unit FPD consists of a pontic, two retainers on each side of Pontic and connectors which connect pontic to retainers. Create a free website or blog at WordPress.com. It is more aesthetic; hence, it is indicated for anterior teeth. To these facings, the gingival area is again built with porcelain and glazed for tissue tolerance. Class II : Loss of ridge height, with normal width. Ovate pontic was designed by Deeway and Lugsmith in 1933. Longevity of fixed partial denture and abutment rely on In the conventional bridge, the pontic is joined to the retainer solely by means of a solder joint which forms the connector. Studer S 1997 stated that because of lack of interdental gingiva , open interproximal spaces appear , thus increasing exchange of saliva and air , presents a high risk of food impaction. Access to them and the patient’s dexterity should be taken into account in designing pontics. If the contact ‘is extended onto the alveolar mucosa, severe ulceration may be produced, All ceramic gingival masks made of pressed glass ceramics. Porcelain is added to the gingival surface and contoured according to the ridge, finally glazed and finished. Donald A. stated that, the fused multiple pontics design, which was thought to be best for mandibular posterior segment can be used in other parts of mouth also. The major disadvantage of this system is its complex design, which leads to accumulation of plaque and gingival inflammation. Ridge lap pontic in which tissue surface is inaccessible to cleaning devices. The saddle pontic has a concave fitting surface that overlaps the residual ridge buccolingually. Otherwise it will not serve the same occlusal functions. The occlusal surface of the pontic should resemble the occlusal surface of the tooth it replaces. What are types of minor connectors? – Mechanical failure due to improper framework. 52. Pontic designs are classified into two general groups: Mucosal contact & Non-mucosal contact based on the shape of the gingival side of the pontic. It must look as tooth-like as possible. – Food entrapment leads to tongue habits. Highly glazed porcelain is the material of choice for this surface. Tinker 1918 named it âSanitary Dummyâ pontic. Conventional bridges are named depending on the way the pontic (false teeth) is attached to the retainer. connectors • the portion of a fixed partial denture that unites the retainer and pontic 54. connectors Classification 1. If veneer is to be applied cut back the wax pattern approximately. – Anterior segment â modified ridge lap is the design of choice, as esthetics influences the pontic design. Belorend introduced multiple fused pontics in 1981. Stein RS 1966- Stated that pressure free contact over a small area produce highly esthetic results in contrast to classic requirements for pontics as this design produces an emergence profile looking similar to that of the natural tooth. Traumatic extraction results in severe bone resorption, surgical ridge augmentation, and soft tissue correction enhance esthetics. Lute the pontic to the retainers and, for additional stability, connect its cervical aspect directly to the master cast with sticky wax. FREE Shipping by Amazon. Portion of a fixed bridge that unites retainer and pontic. Shoher and Whiteman introduced Inzoma pontic in 1983. 1. 10 Unusual Denture for most common conditions! This is necessary when they are made of different materials. During treatment planning, the diagnostic cast should be thoroughly examined. In the lower teeth the lingual cusps aid to protect the tongue. Fill in your details below or click an icon to log in: You are commenting using your WordPress.com account. Conical pontic- placed in extraction site. The connector consists of a loop on the lingual aspect of the prosthesis that connects adjacent retainers and/or pontics. Tissue contact area of pontic is passive. Alignment of abutment teeth and retention. The design of the sanitary pontic allows easy cleaning, because its tissue surface remains clear of the residual ridge. Tissue contacting is rounded bluntly and set in concavity of the ridge. Also called âFish Belly Appearanceâ. In cases with overhanging hyperplastic tissues, surgical excision of these issues should be carried out. FPDs in which only one side of Pontic is attached to a retainer … Use of precious metal is saved because of framework. The modified ridge lap design is the most common pontic form used in areas of the mouth that are visible during function. Large angle embrassure spaces around tissue contact collect debris. The retainers are cemented to the prepared abutment teeth. – They determine tissue contact and clearance. The ovate pontic is the most esthetically appealing pontic design. The mandibular molars are provided with large embrasures for better cleaning and aesthetics is not critical. Often called egg-shaped, bullet-shaped, or heart-shaped. 4. Nonrigid connectors have been advocated for fixed partial dentures. Patient must be instructed in how to clean the gingival surface of the pontic with floss. Rigid connector cast connector soldered connector 2. semi-rigid connector -interlocks custom made 3. They are indicated for cases with reduced inter-arch space, the pontic should give the appearance of an exaggerated occlusoÂgingival dimension. Span: The length of the alveolar ridge between the natural teeth where the bridge will be placed. Minimal-preparation minor retainer(s) are also used for minimal-preparation where the occlusion is favourable. Contact with the labial slope of the ridge should be minimal (pin point) and pressure free (modified ridge lap design). 3. pontic, connectors, and retainers. 3. 20-44). A major retainer for a conventional posterior bridge should not be less than an MOD inlay with full occlusal protection. volume of ridge tissue is established, a socket depression is sculpted into the ridge with surgical diamonds or electrosurgery. In fixed Prosthodontics, connector refers to the portion of a fixed partial denture that unites the retainer and pontic. This pontic is more aesthetic as it appears to arise from the ridge like a natural tooth. It is attached to the backing occlusally with the help of retentive pins. Changes in the residual ridge, opposing occlusion and proximal space affect the success of the restoration. This geometry permits increased connector size. Glossary of Prosthodontic Terms ( GPTâ No. When vertical height is insufficient, residual ridge is contoured is reshaped. The movement in a nonrigid connector is enough to impede the transfer of stress from segment being loaded to the rest of the FPD. Commercially available porcelain denture teeth with pins can be altered to obtain this facing. Gingival response to pontic: JPD 1968 (19). Arlon G. (1968) studied the effect of various pontic materials on gingiva. Retainers. Excellent class I defect is corrected by subepithelial or submucosal graft. Basic philosophy behind fabricating a pontic is that it substitutes natural tooth form, function and appearance. Reichenbach E 1931, Dewey K W 1933 also stated that after extended periods of service the adjacent soft tissue tends to become inflamed, and the alveolar bone is resorbed. stability to the prosthesis and also minimizes the stresses . ( Log Out / An inverted orientation of the nonrigid connector … Made entirely of metal if esthetics is not important. Cemento-enamel junction of abutment tooth/ teeth used as vertical reference points. a) all pontics materials tested produced some change when they were in contact with the gingival tissue. The lingual surface is designed with hygiene as the primary concern. 4.Occlusal contacts must be placed so as to avoid metal porcelain fracture during centric and eccentric movements and contacts. Class III : Loss of both ridge width and height. But studies have shown that the finish of the surface is more important than the material used in maintaining tissue health.Â. Pontic or the artificial crown derives its name from a latin word “Pons” which means bridge. Design of multiple pontics â JPD 1981 (46) 634-636. There are three types of fixed connector: They are made by wax patterns of the retainers and pontics connected by wax being produced so that the bridge is cast in a single piece. Clinical results showed that plaque formation was noticed in all the pontic materials used. o Connector: connects the pontic to the retainer. It has two proximal slopes/bevels on either side of the central bulk. Only 3 left in stock - order soon. With time-lapse after extraction, there is a migration of adjacent and opposing teeth â they should be orthodontically repositioned and modified with complete coverage. Saddle or ridge lap designs should be avoided because the concave gingival surface of the pontic is not accessible to cleaning with dental floss, which will lead to plaque accumulation. and pontic, is usually recommended in such situation. Pontic is defined as an artificial tooth on a fixed partial denture that replaces a missing natural tooth, restores its function and usually fills the space previously occupied by the clinical crown. 5. Podshadley and stein (1968) contradicting didnât find any relevance between soft tissues and pontic fabricated from gold alloys ,resins gazed ceramics . Can i know your references? The major factors that determine the design of a pontic are: Space available for the placement of the pontic. Thus a thorough consideration and implementation of above said will contribute towards the successful design of a pontic, Majority of researchers believe that inflammation of alveolar mucosa under pontic is caused by the accumulation of plaque on the basal surface – Stein R S (1966). Anterior pontic design â JPD 1984 (51): 774-76. Study 59 Pontics and Connectors flashcards from Ashley Z. on StudyBlue. Gingival colored prosthesis is a solution for correcting large alveolar defects associated with esthetics and phonetic problems, The success of a fixed partial denture depends on the proper design of the pontic. If mesiodistal width is reduced, metal pontic with porcelain or acrylic facing is advised. Backing with retentive pins to accept a reverse pin facing. Cary P. et al in 1997 derived a simplified techniques for stabilization of the pontics. A smooth rounded ridge is best for the placement of a pontic. – Provides access to oral hygiene procedure. [ den´cher] a complement of teeth, either natural or artificial; ordinarily used to designate an artificial replacement for the natural teeth and adjacent tissues. Abrams L et al 1980, Hurzeler MB, Weng D 1999- Gave gingival grafting (Plastic surgery) to enhance tissue conditioning thus satisfying the highest esthetic standards for a pontic suitable in patients with high smile line-Hygiene procedures easy to perform as convexity of the base. Cut the other end of the post so it does not interfere with the occlusion, otherwise leave it as long as possible. Occlusogingival Height and mesiodistal width of edentulous space: PFM ridge in long span with reduced occlusogingival height can result in porcelain fracture. He also suggested this design for posterior segment. Major or minor. It is important too that the embrasure spaces and connectors should be smooth and cleansable. In the case of a long-span bridge, A technique derived by Ruhlam et al 1967 may be advanced. Occlusal plane correction is done before the fabrication of the fixed prosthesis as in the case of supra eruption of opposing teeth. – If complete metal retainers are used â all metal pontic. its emergence from the ridge appears identical to that of a natural tooth. Fig. Occlusogingival thickness of pontics should be no less than 3mm and adequate space below it for cleansing. Tissue contact should pertain to the crest of the ridge. ... Conntek RL-70046-GB Upto 15-Feet Heavy Duty 12/3 Coiled Spring Extension Cord 15/20-Amp female Connector. However, the bridge retainer codes vary depending on whether or not an abutment was used to attach the bridge retainer to the implant body. – When partial veneer retainers are used, prefabricated facings are indicated using same metal as retainers. This pontic has a convex tissue surface, which contacts the tissue at one single point without any pressure. Conical- placed directly in an extraction socket, Modified ridge lap- satisfies esthetics and hygiene, 3. Horizontal tubular slot in the facing runs from centre to lingual side. Perel in 1972 presented modified sanitary pontic. 5. namely retainer, pontic and connectors Connectors are the components of partial fixed prosthesis or splint that join the individual retainers and pontics together. Thanks! – Not used in long span and high-stress areas. Both intracoronal and extracoronal restorations can be … Refine the pontic cut-back where access is improved by removal of the first retainer. It is indicated in cases with limited inter-arch distance. The authors concluded that, whatever material used maybe and are smoothened as much as possible, they must be cleaned regularly. Facing and backing available with the gingival backed tip. The gingival surface is the most interesting aspect of the pontic design. Facings are supplied with standardized metal backings with male plug which fits into female groove on lingual aspect of facing. Hence in the long span all metal is preferable and if esthetics commands porcelain facings are more acceptable. [The retainer is an important appliance that unites the abutment teeth with the suspended portion of the bridge. Variables that may influence the longevity of an FPD and its abutment include occlusion, span length, bone loss, and quality of periodontium. The facing consists of a flat lingual surface with two retentive pins. ( Log Out / COMPONENTS FPD has three elementary components, that are: Retainer Pontic Connector 5. Cannot be used in decreased occlusogingival height. Main advantage is increased strength, fever laboratory steps used in high stress, mandibular posterior region and even in bruxist. Pontics and Connectors - Fixed Prosthodontics 6473 with James at University Of Minnesota School Of Dentistry - … Placement of modified full coverage retainers. All the functions should be executed in a manner compatible with oral health and comfort. Tissue contact should resemble a letter T whose vertical arm ends at the crest of the ridge. The space created due to the loss of a tooth is usually sufficient for the fabrication of a good pontic. ( Log Out / In 1987 Abrams H et al in a retrospective study of partially edentulous patient showed that 91% of edentulous anterior section â Alveolar defects . Fixed-movable bridges have a major retainer at one end of the pontic and a minor retainer (carrying the movable joint) at the other. Conversely, nonrigid connector functions as a stress breaker between retainer and pontic and have thus been recommended to diminish the forces instead of usual rigid connector. 1.Should provide uniform veneer of porcelain of approximately 1.2mm. Notes from lectures during the course of Dental Technology. Stein R S 1966 , Cavazoz E 1968 : the convex basal surface , which rests on small area on alveolar ridge , fulfills the recommendations made in dental literature with regard to hygiene procedures and prevention of irritation of underlying soft tissues. These are prefabricated pontic facings, which resemble sanitary pontics described before. Round and cleanable but tip is too small in relation to overall size of the pontic. Ovate pontic-appears to emerge from gingiva like a natural tooth. Â Â Wider embrasures are provided for posterior teeth for better cleansing. Can wear Dentures overnight invites Denture Stomatitis? When an occlusal load is applied to the retainer on the abutment tooth at 1 end of a fixed partial denture with a pier abutment, the pier abutment may act as a fulcrum. Occupies missing space acts as space maintainer. He also showed that, plaque accumulation and calculus deposition are eliminated and no: of surfaces the patient must clean is reduced and maintaining oral hygiene is simplified. Tissue contact should be made by the backing and not the facing backing junction. The gingival surface is usually supplied uncontoured. Socket-preservation techniques should be performed at the time of extraction to create the tissue recess from which the ovate pontic form will emerge. The indications for the use of nonrigid connector in fixed prosthodontics are. Pontic serves to restore the mastication, speech to maintain tooth relationships, both interarch and intra arch, and also to satisfy patients esthetic and psychological needs by eliminating the space in dentition. They are not used while opposing natural dentition and resin tooth. This can be done in aesthetically low profile areas like lower anteriors and upper posteriors. They should also be as easy to clean as possible. It should be remembered that the entire gingival bulk is custom fabricated in a modified pin facing whereas in a harmony facing a portion of the gingival bulk is custom fabricated. Criteria for choosing a suitable retainer includes: The principles guiding the design of the pontic are : All surfaces of the pontic especially the ridge surface, should be made as cleansable as possible. Change ), You are commenting using your Google account. Therefore mentioned measures taken for soft tissue conditioning are repeated at intervals of 2 weeks until satisfactory contour and pseudo/papillae are formed. Weakest part of an FDP • FDP material o Can be metal, metal ceramic, ceramic, lab processed composite, fibre reinforced acrylic/composite o Fibre reinforced composite is only used in medically compromised older adults needing esthetic anterior tooth replacement • Pontic design Joseph et al (1990) studied the relationship between surface roughness of the pontics and dental plaque accumulation. Contact with the facial /buccal surface of the ridge is essential to provide a natural appearance. Â Tissue surface of the pontic shows a ‘T’ shaped contact. Attach sprue, invest, cast and finish as normal, the post is removed during finishing stage, after the pontic is attached to the retainers. Prepare a working cast in the usual manner. – 3mm of clearance is recommended for hygiene reasons. When the vertical height is insufficient, the residual ridge is lowered and reshaped to allow space for physiologic pontic. The conical pontic is easy for the patient to keep clean. Concavity is created using provisional restoration and also surgically. Â Contact with the buccal slope of the ridge should be minimal (pin point) and pressure-free (modified ridge lap design-discussed later). If a pinpoint contact is given for a case with ridge resorption, unaesthetic black spaces may become visible. The occlusal forces applied to a fixed partial denture (FPD) are transmitted to the supporting structures through the pontic, connectors, and retainers. They differ from Harmony facings (discussed later) in that the entire gingival portion of the facing is custom-made.
