Prior
Patient's \_\_\_\_ Appt: • Medical & Dental History • Panoramic & periapical radiographs of potential abutment teeth- must be within previous year. • Complete periodontal & restorative charting • Diagnostic Casts • Pulpal evaluations of potential abutment teeth
First Appt
Patient's \_\_\_\_ appt: • Review radiographs • Any additional radiographs taken • Identify any additional teeth requiring extraction • Pulp test potential abutments, if not previously done • Identify teeth requiring endodontic treatment • Need for periodontal therapy already determined • Diagnose necessary restorations: – Some identified at first visit – Amalgams, composites – Single crowns, FPDs, RPDs, complete denture – Surveyed crowns: abutment • Large amalgam • Extensive caries • Inappropriate contours: not determined until diagnostic cast surveyed – Soft tissue, residual ridge support – Vertical space • Patient in occlusion, Diagnostic cast • Bony interference: tuberosity • Supra-erupted teeth • Diagnostic Cast evaluation – If necessary, remake impression for adequate extensions for final impression trays • If needed, periodontal treatment of remaining teeth – Also if periodontist advises to perform deep scaling and root planing and re-evaluation: You need to have the long-term prognoses of the remaining teeth obtained prior to the prosthodontic consult.
Second Appt
____ abutments should not be clasped
Usually seen in PM regions of maxilla
- Stand alone tooth with edentulous spaces on
