Single Complete Dentures -74 3. Avoid a complete single denture against an opposing 6- 8 teeth in the anterior of an arch - it can lead to resorption, or loosening or fracture of the denture CONSIDER FABRICATING AN OPPOSING PARTIAL DENTURE IF THERE IS EXTENSIVE LOSS OF POSTERIOR TEETH IN THE OPPOSING DENTITION 4. If a partial denture is to be fabricated opposing a complete denture, the dentures should be made at the same time. RPD preparations are made, an impression taken, and the framework fabricated. While the framework is being fabricated, the final complete denture impression is made, and the record base constructed. The framework is adjusted, denture base is added to the framework and jaw relations recorded between a complete denture occlusion rim and an opposing occlusion rim on the framework. Setting the complete denture and RPD denture teeth at the same time allows maximum control of tooth positions to optimize the occlusion. Any crowns or bridges should be waxed up against the <strong>CD</strong> tooth setup for the same reason. 5. Setting of the anterior teeth is more difficult. Setting them for esthetics may result in a placement which produces excessive overbite in relation to the natural teeth. This will compromise stability of the denture. Anterior teeth are often set in a compromised position, taking esthetics and function into consideration. Maxillary teeth may have to be set higher to avoid excess overbite, which compromises display of the incisal edges. 6. Posterior denture teeth require more grinding to obtain stable centric contacts. Tip: After obtaining the proper vertical dimension, increase the incisal pin height 1mm on articulator (i.e. increase OVD 1mm) set all posterior teeth, let wax harden, return pin to original position and grind occlusion until pin touches table. Use a type IV stone (e.g. Silky Rock) on the opposing dentate cast to minimize abrasion during setup.
Single Complete Dentures - 75 7. A cast metal complete denture base can be considered if fracture of denture has occurred repeatedly. Fractures usually are caused by the heavy forces from the natural dentition in combination with occlusal contacts on inclines (causes flexing of the denture) or impingement on a bony midline (again causing wedging forces on opposite sides of the denture). 8. Denture teeth will wear more rapidly against natural teeth. Patients must have more frequent recalls to adjust the denture occlusion to prevent changes in stress distribution. 9. Never use porcelain denture teeth against natural teeth - they can cause severe attrition of the natural teeth. It is preferable for the denture teeth to wear, rather than the natural teeth.
