9. Preparation of the Remaining Dentition

Unfortunately, the preparation of the remaining dentition is often neglected. This is especially regrettable, since in many cases the optimum cast partial denture can only be achieved when the teeth to be clasped are properly prepared, This preparation involves:

-  improving the position of the survey line

-  removing interferences to the path of insertion

-  the preparation of recesses for dental rests

In all cases, diagnostic models (also known as study or planning models) are required. These models are surveyed, but not in a casual manner, as if only for provisional information. On the contrary, a definitive survey line and the final path of insertion must be determined at this stage in the treatment plan.

This is certainly possible, since the path of insertion is determined by the undercuts present. When the model is fixed in the position representing the path of insertion, the survey line is drawn. Only after the preceding steps have been taken can one recognize which, if any, corrections must be made on the remaining dentition.
