Abstract

A few authors have reported good clinical results using double crown removable partial denture (RPD) with a few remaining teeth. Hybrid telescopic double crown is a good indication for a patient with poor periodontal condition and/or few remaining teeth after extraction, especially located in cross-arch position. In this case, there was a poor periodontal condition with teeth mobility. Several teeth with poor prognosis were extracted. Remaining anterior teeth was restored with fixed prostheses and edentulism was restored with Kennedy class I removable partial denture in maxilla. In mandible, it was hard to restore with clasp removable partial prostheses because of bilaterally isolated remaining teeth so that hybrid double crown removable partial denture with friction pin was suitable for this case. The objective of this report is to discuss the characteristics and the utility of hybrid double crown prostheses using a few remaining teeth in mandible.
