RPD Review Questions

Answer to Question #107


The correct answer is

Incorrect. Although it could be used, there would be undesirable tissue coverage---especially since the ridges are good and the abutments strong.

Incorrect. A modified palatal plate is used for maxillary class II RPDs.

Incorrect. In general, a horse-shoe major connector is undesirable because it lacks rigidity unless quite bulky. It is only used to circumvent large inoperable tori or when the patient is a big-time gagger. Neither of these circumstances are mentioned in the question stem.

Correct. These are perfect circumstances for an anterior-posterior palatal strap major connector. The tooth-borne areas are large, the abutments are strong, and the residual ridges are of good size and quality.
