ABSTRACT
Emphasis has been placed in earlier chapters on the general approach to planning. Here the process is taken to the final, practical stages. The following factors should be considered before clinical tooth preparation is started: • Study casts • Photographs • Trial preparations • Appearance • The final impression • The temporary crown
Full arch study casts are useful in a variety of planning procedures described earlier (Chapter 5) and below. In addition, the opposing cast may be articulated with the working cast, provided that it has not been damaged during the planning stages and there has been no occlusal adjustment or other restorations since the impressions for the study casts were taken.
