[Use of telescopic crowns for rehabilitation with removable dentures. 1. Principles].

This paper sheds light on retention systems using telescope crowns in fixed and removable partial denture prosthodontics. Although relatively old in concept, these procedures are enjoying renewed interest due to the considerable progress made in precision machining at the dental laboratories. The use of these rehabilitations, simple to understand, nonetheless requires absolute precision regarding their achievement. The practitioner and dental technician must bring to this kind of work a maximum of complementarity; communication must be constant for the reciprocal understanding of the problems faced by each of them. It is important to emphasize the ease of application and the number of solutions proposed by these telescope systems which, despite the ever growing quantity of new techniques must be maintained in the prosthetic and therapeutic possibilities.
