Modified Palatal Plate Major Connector
Posted on 11/11/2011
Given the drawbacks to the design of the palatal plate - especially the diminished sense of taste and compromised tongue function - an alternate design termed the "modified palatal plate" was introduced. The design is used specifically for Kennedy Class II RPDs and especially in cases of an inoperable torus.
The design elements include:
1. Anterior and posterior borders are determined by the location of the most anterior and most posterior rest seats.
2. The plate is extended to create a lateral plate on one of the palate. This extension ends with a butt joint at the entrance to the hamular notch.
3. All borders of the plate are beaded. The beads should end 6mm from the gingival margin.
Advantages to the modified palatal plate:
1. Less coverage of the palate than the palatal plate
2. Offers excellent rigidity and support via the posterior extension
3. Offers a good solution for inoperable torus
