Preparation in the Mouth for RPD Frameworks
Posted on 03/20/2012
We are now at the final topic of discussion for removable partial denture frameworks - mouth preparation. While we often see doctors sending an unprepared cast to the laboratory for lab preparation, ideally, the preparation should be done prior to impressioning. Our discussion over the next several blogs will discuss the various tooth preparation guidelines.
First, we will focus on the order of the tooth preparation.
We recommend the following sequence for tooth preparation:
1. Create guide surfaces including those for guide plates, minor connectors, lingual plating and esthetics
2. Reduce interferences such as inclined teeth
3. Contour teeth for improved clasp location and placement
4. Create access for minor connectors between the rests and the major connector
5. Prepare rest seats
6. Prepare retentive recesses
