Telescopic Posterior Cantilevered Resin-Bonded Fixed Dental Prostheses: An Interesting Alternative for Severely Tipped Teeth Illustrated by a Case Report

Abstract

Purpose: To present a clinical case demonstrating the fabrication of a two-stage telescopic posterior cantilever resin-bonded fixed dental prostheses (PC-RBFDP) on severely mesially tipped mandibular molars to replace a missing premolar and molar with a one-year follow-up.

Materials and methods: To address clinical challenges, premolars and molars were replaced using a telescopic two-stage design. Half-occlusal veneer preparations were performed on mesially tipped molars. Two frameworks were fabricated with a 3Y-TZP/5Y-PSZ multilayer zirconia framework, onto which two glass-ceramic crowns were secondarily bonded. This approach enabled prosthetic axis adjustment, thus avoiding the contraindications of a monobloc PC-RBFDP and the biological challenges induced by an implant-supported crown. Digital impressions and CAD-CAM technology were utilized to manufacture PC-RBFDPs, and bonding was achieved with a universal resin luting cement containing 10-methacryloyloxydecyl dihydrogen phosphate (10-MDP). Haut du formulaire Results: After one year, the clinical case demonstrated functional and aesthetic success. The telescopic design facilitated the fabrication of a PC-RBFDP for a patient who refused implant therapy, thus overcoming the limitations of a monobloc design.

Conclusions: Despite the limited clinical follow-up and the need for further evidence to support this therapy, the telescopic design shows potential as a viable solution for fabricating PC-RBFDPs in cases where the abutment tooth is severely tipped. This innovative approach may expand the indications for PC-RBFDPs.
