Step 1 in RPD Framework Design: Surveying
Posted on 10/11/2011
The first step* for proper design of the RPD framework is to survey the diagnostic cast. If possible, surveying should be done by the practioner using a flat surface table and a surveyor. Should the practioner not have a surveyor or not feel comfortable surveying, the lab will need to perform the initial survey before teeth are prepared.
The purpose of surveying is to determine:
1. Path of Insertion: Determine the most effective and advantageous path of insertion from both functional and aesthetic requirements
2. Guiding Surfaces: Determine which if any teeth can be used as guiding surfaces naturally or through preparation
3. Undercuts: Locate and measure recesses and undercuts
4. Interferences: Identify potential hard or soft tissue interferences
