Application of single-retainer all-ceramic resin-bonded fixed partial denture in replacing single anterior tooth

doi:10.7518/hxkq.2017.04.011

Abstract

Abstract:

Objective In this study, we aimed to evaluate the clinical effect of single-retainer all-ceramic resin-bonded fixed partial denture (RBFPD) on the single anterior tooth loss patients. Methods A total of 20 single-retainer all-ceramic RBFPD were fabricated and evaluated in a two-year follow-up observation. The restorations were examined on the basis of the Ame-rican Public Health Association (APHA) criteria. Results A total of 20 single-retainer all-ceramic RBFPD achieved class A evaluation after a six-month follow-up observation. One single-retainer all-ceramic RBFPD was classified as class B for secondary caries after a one-year follow-up observation. After a two-year follow-up observation, one single-retainer all-ceramic RBFPD was classified as class B because of secondary caries, and one single-retainer all-ceramic RBFPD was classified as class B because of fracture. Conclusion Single-retainer all-ceramic RBFPD is a promising and optional method in replacing single anterior tooth.

Key words: single-retainer resin-bonded fixed partial denture, single anterior tooth loss, all-ceramic
