Abstract

Telescopic denture has advantages such as transfer the occlusal force to the long axis of the abutment, easiness of oral hygiene management, increase of retention and stability, splint effect due to secondary fixation between abutments and have been reported a higher success rates than conventional removable partial denture (RPD). However, there are disadvantages such as complex laboratory procedures, long treatment periods and high costs, and high incidence of complications. This clinical report describes two cases, a 4-point supported telescopic denture using telescopic crown and a 2-point supported telescopic denture using conical crown with functionally satisfactory results. Frequent complications of telescopic denture, which are reported in various literature were reviewed. Clinical and laboratory procedures were performed in consideration of complications that reported.
