Components of a Removable Partial Denture (RPD) Practice Test 2026 - Free Removable Partial Denture Exam Questions and Study Guide

The main idea here is that a palatal plate major connector covers a large area of the palate, and a palatal torus creates a bony prominence with potential undercuts that can block proper seating and cause pressure or trauma. If the torus would interfere with the plate, the connector would not fit passively and could irritate tissues, compromise fit, and hinder hygiene. Because of that, the design should be avoided when a palatal torus would interfere. In such cases, an alternative major connector that avoids covering the torus (like a horseshoe or other non-palatal design) is preferred, or surgical/relief options might be considered if appropriate.
