Following are the results of a study made on the influence to the prepared tooth form, when the abutment tooth preparation with full cast crowns are done for the Maxillar Left Fixed Prosthodontics three-unit bridge in Random Position. The prepared teeth are the Second Premolar and the Second Molar (The "Second Premolar" is abbreviated to [figure] and the "Second Molar" is abbreviated to [figure]). 1. The reduced extent of occlusal surface was excessively large at [figure] and [figure] buccal cusps, while it was excessively small at Central grooves. 2. The reduced extent of axial surface was excessively small at [figure] and [figure] all surfaces. 3. The reduced extent of subgingiva tended to be shallower than the designated depth of 1.0mm at the all portions. 4. As for the degree of axial taper, its made steeper toward the buccal and distal surface both [figure] and [figure]. 5. As for the relative degree of axial taper, it get the largest in degree on bothsides between [figure] medial surface and [figure] distal surface.
