The analysis of quality of teeth preparation was carried out at manufacturing of metal-ceramic crowns. The taper of 57 prepared teeth was assessed on working casts in vestibulo-oral and medio-distal projections by means of an original technique. In most cases excessive taper was observed, sometimes up to 50°. The taper was greater in vestibulo-oral plane than in medio-distal plane.

Keywords:
