Abstract

The purpose of this article is to classify the types of telescopic prostheses that protect natural teeth as an alternative to traditional removable prostheses, and to explain their advantages, disadvantages, indications and clinical significance in order to minimize the problems of removable dentures. Telescopic prostheses consist of an inner (primary) crown permanently cemented to an abutment and an outer (secondary) crown attached to the prosthesis. Primary crowns protect the abutment from bruises and thermal irritation, and also provide retention and stabilization of the secondary crown. The secondary crown combines the primary crown with the prosthesis to form a telescopic unit, providing prosthetic retention and stability.Â Â

Highlights

This Many different systems are improved for fixed partial dentures as a retention element in the prosthetic rehabilitation of partial edentulism [1,2]
These crowns consist of an inner or primary telescopic coping permanently cemented to an abutment and a compatible removable outer or secondary telescopic crown rigidly attached to a removable prosthesis
Telescopic crowns have been used successfully in removable partial dentures (RPDs) and fixed partial dentures (FPDs) supported by endosseous implants in combination with natural teeth, including overdentures [12,13]

Summary

Introduction

This Many different systems are improved for fixed partial dentures as a retention element in the prosthetic rehabilitation of partial edentulism [1,2]. At the beginning of the 20th century, telescopic crowns began to be used as retainers for removable partial dentures (RPDs). They are known as double crown and sleeve coping or Conusrone, a German term that describes the cone-shaped design. The term telescopic prosthesis refers to the type of prosthesis that includes double crowns as a retainer or attachment. These retainers consist of two crowns; a primary or inner crown cemented to the abutment and a secondary or outer crown connected to the prosthesis (Fig. 1) [10,11]. A telescopic prosthesis is a more versatile alternative for these patients because the prosthesis can be repaired without reconstruction of the entire superstructure, despite a localized failure
