Prosthodontics
Core concepts
Understand complete and partial denture design, including support, retention, stability, and the biomechanics of removable prostheses. Know Kennedy classification for partially edentulous arches and the components of a removable partial denture: rests, clasps, connectors, and the denture base. Know the principles of fixed prosthodontics: tooth preparation, margins, impression techniques, provisional restorations, and cementation.
Occlusion and implant prosthodontics
Know occlusal concepts relevant to prosthodontics, including centric relation, maximum intercuspation, and balanced occlusion in complete dentures. Understand implant-supported prostheses: single crowns, bridges, and overdentures, and the importance of passive fit and occlusal loading.
Traps
Questions often test the difference between support (from rests and tissue) and retention (from clasps). Another trap is confusing Kennedy Class I (bilateral free-end saddle) with Class II (unilateral free-end). In fixed prosthodontics, margin fit and minimal preparation are commonly tested. Do not assume a denture complaint is purely aesthetic - check occlusion, extension, and fit.
Rule of thumb
For any prosthesis, assess support, retention, and stability before adjusting; most complaints trace back to one of these three.
Worked example
A patient with a Kennedy Class I partial denture complains of movement: the free-end saddles lack distal support, so the design must rely on rests and a major connector, and the impression must capture functional tissue form.
