Guiding Surface Preparation for Minor Connectors and Lingual Plating
Posted on 03/28/2012
While guiding surface preparation for guide plates is the most common guiding surface preparation, there are two other framework designs that may require guiding surface tooth reduction: minor connectors and lingual plating.
Minor Connectors:
In situations where the minor connector passes between two teeth into the rest seats, it is often necessary to reduce the interproximal area to create adequate space. Please see the picture to the left.
Lingual Plating:
In mandibular RPDs with a lingual plate major connector, it is often necessary to prepare the lingual surfaces for the plating. This is also applies to posterior teeth that require lingual plating for stability. Any reduction should avoid impact on the cervical third of the tooth.
