RPD Review Questions

Answer to Question #38


The correct answer is

Incorrect. The statement is true. The RPD will transfer stresses to the abutment teeth through the rests, guide plates, major and minor connectors, and retentive arms.

Incorrect. The statement is true. The RPD will transfer stresses across the arch through the rests, guide plates, major and minor connectors, and bracing and retentive arms. This is an important positive attribute because it is through this mechanism that stresses are dissipated throughout the arch rather than being concentrated in one area.

Incorrect. The statement is true. The completed RPD (with denture teeth in the posterior edentulous areas) will help to minimize super-eruption of the opposing teeth. It should be pointed out, however, that super-eruption will not be totally prevented. As the plastic denture teeth wear, some super-eruption will take place.

Correct. Although plating would prevent permanent tooth movement to the lingual, it will not prevent movement to the facial which is the normal direction of migration, particularly in the presence of periodontal disease.
