Repairing aBroken Complete Denture 223putty while it is soft to provide retention of the putty to the plaster base of the repair cast. Treating the Complete Denture Patient, First Edition. Edited by Carl F. Driscoll and William Glen Golden.© 2020 John Wiley & Sons, Inc. Complete denture (if few teeth left, with poor prognosis); if replacement of missing teeth is very complex or costly D. Indications for RPD's 1. lengthy edentulous span (too long for a fixed prosthesis) 2. no posterior abutment for a fixed prosthesis 3. COMPLETE DENTURE PROSTHODONTICS A Manual For Clinical Procedures Other systems will have a screw hole in the top of the ball and a screw that is placed in the hole to attach it to the implant. The denture pieces are removed from the cast and the area under the fracture site is inspected for any defects. If this were done on a patient’s denture, a repair acrylic matching the denture’s original acrylic would be chosen. This study was carried out on 40 Iraqi patients with an age range between ( 55 – 65 ) years . You may discover that you're not cleaning your dentures often enough, not using the right cleaners, or damaging your dentures as you clean them. Whenever I put on the full complete denture, caused soreness on my corern tooth and facing problem of using it to eat. Although this option is not a definitive treatment, the patient and his parents were satisfied with his improvement in chewing and speech, as well as with the aesthetic benefits. The quick‐setting plaster will not bond with this material and will need to have some sort of mechanical retention provided. It is necessary that this amount of gap be present to allow enough visual and working access, so the repair acrylic can be placed and fill the entire repair site. Dentures should not be considered a replacement for teeth. As with any fracture, this must be corrected if the repair is to be successful. Replacing Teeth onaComplete Denture 217Figure 35.7 Place the matrix containing the replacement tooth into position on the denture.Figure 35.8 Overfill the prepared areas of the denture with autopolymerizing repair resin.Figure 35.9 Several teeth in this denture have fractured.Figure 35.10 Carefully remove the broken teeth.Figure 35.11 Select replacement teeth and fix them in place with sticky wax. For demonstration Figure 36.1 The most common fracture of a complete denture is the midline fracture of the maxillary complete denture.Figure 36.2 Align the parts of the fractured denture and splint them into position with coat hanger wires.Figure 36.3 “Tack” the wires to the teeth with sticky wax.Figure 36.4 Cut pieces of paper clip and bend them into a loop to make good retainers for the repair cast.Figure 36.5 Block out the ridge area away from the fracture site with polyvinylsiloxane putty. Moisture from the water bath in the pressure pot can cause a rough surface to form, which must be removed after the denture is cured. A mounting plaster base is poured to complete the repair cast.

The brush is first “wetted” in the liq-uid monomer, then it is dipped in the polymer powder. Implant tooth is out since I am a diabtetes. The parts are “tacked” with sticky wax into position on the cast base. complete dentures. But denture adhesives should not be used to fix old or poorly fitting dentures - and should generally be avoided. Sticky wax is placed on the lingual (palatal) surface of the tooth to hold it in place (Figure35.3).The labial margin of the tooth is not disturbed. Denture adhesives help your dentures stay in place and make them feel more secure. This can occur with plastic teeth as Figure 36.29 Place the repair cast with the denture in a pressure pot water bath to cure.Figure 36.30 Check to see that the acrylic is of good quality and covers all the desired areas.Figure 36.31 Fit the dentures together to ensure that they occlude properly. In patients with severe resorption of the alveolar ridge, a portion of the inferior alveolar nerve may be exposed (Figure 34.50). See our Privacy Policy and User Agreement for details. The repair can then be shaped and polished to finalize the repair.Figure 35.16 Slightly overfill resin in the prepared area.Figure 35.15 Apply resin to the repair site by the brush-bead method. Special burs are required for adjustment of silicone elastomers. This usually is the result of an accidental drop, although it can occur during function. After the acrylic has set for 10 min-utes, the repaired denture is removed from the stone matrix (Figure 36.12) and finished with successively finer abra-sives until a high shine is achieved (Figure36.13). Complete dentures are relatively economical, easy to fabricate and repair, and provide a level of esthetics and function acceptable to many patients. Edited by Carl F. Driscoll and William Glen Golden.© 2020 John Wiley & Sons, Inc. 2. If this step is forgotten, the acrylic will harden and the brush will be ruined (Figure36.28).

Pink acrylic repair resin is used here to contrast to the red Duralay resin to show the area repaired. They are contraindicated, however, in patients with poor oral hygiene or xerostomia. A conventional complete denture was planned and constructed following the same steps of technique as recommended in adults. Treating the Complete Denture Patient222The following pictures demonstrate how a fracture of a mandibular compete denture is successfully repaired. Neuromuscular control may be the single most significant factor in […] The existing denture is modified to be worn while laboratory work is done so that the implants are not stressed.37Using Implants toStabilize aComplete Denture, Troubleshooting Complete Denture Problems, Denture adhesive powder is sprinkled on the, Equilibrating Complete Dentures Set in a Monoplane Occlusion, Resilient Anchoring and Supporting Elements, Telescopic Anchoring and Supporting Elements. Each patient asked about the problems arises after insertion of complete dentures . Common Denture Problems: Common Causes / Solutions: Denture slipping and moving: Due to shrinkage of jaw bone and surrounding gum tissue, the gums and bone do not support the denture in speaking or chewing -- Reline, rebase or replacement per a dental professional’s recommendation. In this example, the repair acrylic has permeated the crack in the denture tooth. 1. It is very important not to torque the implant by overtightening. Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. Components could be fractured or their threads stripped, or the implants could fail to augment to the bone.In the following example, yellow cap attachment trans-fers are snapped onto the ball abutments (Figure37.6). The easiest method of blocking out the ridge area away from the fracture site is to use polyvi-nylsiloxane putty. A spacer is made to accom-modate the ball abutment transfer. This leads to a constant rocking effect which accelerates bone loss of the residual ridge and causes a steady loss of stabil-ity of the denture, in time leading to a stress fracture of the denture base.The second most common fracture of a complete den-ture is the mandibular fracture. Red repair resin is used here on this technique denture. Treating the Complete Denture Patient22636.2 SummaryFractures occur on dentures most frequently when the residual ridge resorbs to the point where the denture is unstable. Sticky wax is used to lute these braces to the denture base. The replacement tooth for the missing tooth is placed in the matrix and secured in place with sticky wax (Figure35.6).The matrix containing the tooth is placed into position on the denture (Figure 35.7) and can be held there with sticky wax. 4. Treatment plan for restoring the edentulous maxilla with implant-supported restorations: Removable overdenture versus fixed partial design. These are “tacked” to the teeth with sticky wax (Figure36.3). Extra acrylic is added to overbuild the repair site area to assure that there is enough thickness of high‐quality acrylic. The matrix is luted back into place and “tacked” to both proximal areas with sticky wax. Red Duralay resin is used so that the juncture can be easily seen. Gently wet it under a small stream of water (Figure34.53).Permanent soft liners (silicone elastomers) may be indi-cated and are usually limited to mandibular dentures for the treatment of chronic soreness, bruxism, and in the case where no attached gingiva exists (Figure34.54). They must be placed into the putty before it sets, and the loop section needs to extend into the area that will be filled by the plas-ter. Triad® (uncured), clay, or Play‐Doh® can be used to help hold the teeth in place.A matrix of quick‐setting plaster (best) (Figure35.12) or polyvinylsiloxane putty (Figure35.13) is made. 30. • Introduction • Fabrication of complete dentures is dependent on technical, biological, and psychologic interplay between the clinician and the patient. However, most people end up with about 20% efficiency of their natural teeth. Problem #5: They Don’t Stop Bone Loss Diatoric interlocks can be cut into the tooth to provide additional mechanical retention (see arrow).

Note the Triad being used to help hold the teeth in place to make the teeth more stable when the matrix is made.Figure 35.13 A matrix is made of polyvinylsiloxane putty.Figure 35.12 Make a matrix of quick-setting plaster. Cap attachments with stainless steel housings are pressed over the transfers (Figure 37.7). These beads are placed in the repair site to make the repair. The basic design of dentures hasn’t changed in a long time because suction is the best possible way to keep them in place. The denture pieces are replaced on the cast and examined to ensure that they fit precisely back into place (Figure36.20).Approximately 1.5 mm of acrylic is removed from the proximal surfaces of the fracture line on the polished sur-face and 1 mm on the tissue side, forming a gap of 2 mm on the tissue surface and 3 mm on the polished surface (Figures36.21 and 36.22). This process is called “rabbeting” and provides an increased surface area that affords a stronger joint between the old and new acrylic (Figure36.24).Al‐Cote®, a tinfoil substitute, is painted on the area under the site to be repaired (Figure36.25). Cleaning Problems. Enough acrylic is removed from the polished surface side of the denture to allow a gap of 8–10 mm (Figures36.23 and 36.24). Nov. 11, 2020.

A complete denture (also known as a full denture, false teeth or plate) is a removable appliance used when all teeth within a jaw have been lost and need to be prosthetically replaced.In contrast to a partial denture, a complete denture is constructed when there are no more teeth left in an arch, hence it is an exclusively tissue-supported prosthesis. The tissue side is checked for irregularities and these are repaired or smoothed. The “brush‐bead” method is used to overfill the repair areawith repair acrylic (Figure36.11). One must look closely to discern the repair site because the repair acrylic blends together so precisely with the original acrylic (Figure 36.32). The majority of complete denture cases which present in everyday practice can be addressed with the aid of knowledge contained in this instruction manual. Denture Troubleshooting Guide *Burning sensations are usually caused by pressure on a nerve as it leaves nasopalatine or by under-cured bases. The procedure for making a complete denture is as follows: Emergency treatement. 1. This can be a simple hex wrench that the dentist will use to hand‐tighten the screw based on their own judgment and experience, but better sys-tems are designed to be tightened by a torque wrench.These abutment components are attached to the implants and tightened with a torque wrench which will not allow the abutment to be overtightened. www.indiandentalacademy.com. With a little time and focus the prosthesis provided to the patient should provide years of satisfaction and … This not only makes it fit more poorly, it also makes it more brittle and prone to fracture. Troubleshooting Complete Denture Problems 213 Beware of the inferior alveolar nerve! If you continue browsing the site, you agree to the use of cookies on this website. A plaster matrix is made on the labial or buccal side of the tooth being replaced (Figure35.4). Any small pieces are left out and replaced entirely with repair acrylic.Separating medium is painted on the cast at least 10 mm to either side of the fracture line (Figure36.10). A generous area (about 8–10 mm) close to the fracture site is left free of putty coverage (Figure36.5).After the plaster has set, the bracing rods and sticky wax are carefully removed.

Cleaning dentures isn't the same as cleaning natural teeth, so your new daily routine can take some getting used to. “Troubleshooting Dentures” is based on 22 years of experience in denture treatment. The denture and cast are immersed in warm water (115 °F) in a pressure pot for 10 minutes. Repair resin that is closest in color to the denture base would be used with a real-life patient. It is essential that the dentures are inspected to ensure that they fit together before making the repair cast. The ball or reverse cone‐shaped abutments are the most popular (Figure37.5) because they allow for appliance movement. A magnetic metal stud is placed in the endo-dontically treated tooth abutment (Figure37.3) or the mag-nets can be cast to a metal stud (Figure 37.4). complete dentures, it is particularly importantly to accurately capture the vestibular tissue anatomy, in order to create an effective seal for retention. Of course a central recommendation is that there be as close as possible collaboration between dentist and dental technician, both with each other and with the patient. Zitzmann NU, Marinello CP. The sur-faces of the tooth and parts of the denture that will be cov-ered by the matrix are lightly lubricated. They offer the advantage of allowing freedom of movement in several directions.Some abutments are designed to screw into an implant. These magnets corrode very easily and are placed in the overden-ture itself to allow for easy removal.Implants also have improved retention and allow for a variety of implant abutment types.
