Tooth preparation for full coverage-basic principles and rationalized clinical procedures
1Department of Oral Rehabilitation and the Dental Material Science Laboratory, Hadassah School of Dental Medicine, Jerusalem.
Abstract:
The basic principles of tooth preparation for full coverage are discussed and an efficient method is described for the operative procedure. The purpose of each of the four stages in this technique and of the five different diamond instruments which are used in their performance, is discussed. Modifications of the procedure are given for posterior and anterior teeth as well as for teeth with periodontal involvement. Comparing the relative merit of different types of finishing lines, the chamfer type was found most suitable for the majority of preparations.
