Clinical Step-By-Step Approach for Posterior Cantilevered Single- Retainer All-Ceramic Resin-Bonded Fixed Dental
Purpose:
This clinical report describes, in detail, a step-by-step protocol for the fabrication and adhesive luting of a posterior cantilevered single-retainer all-ceramic resin-bonded fixed dental prosthesis (PC-RBFDP) on the basis of current clinical knowledge and scientific data.
Materials And Methods:
A 32-year-old patient presented with a missing mandibular molar previously extracted due to endodontic-periodontal complications. After rejecting implant therapy, a PC-RBFDP was proposed and accepted. The restoration was designed as a partial occlusal veneer retainer in 3Y-TZP zirconia, with a feldspathic buccal veneer and a compressive pontic. Tooth preparation was limited to enamel, and the intaglio surface was sandblasted with 50 µm aluminum oxide and treated with a universal primer. Adhesive luting cementation was performed using preheated resin composite under rubber dam isolation and a strictly light-cured protocol following the 'no-finishing concept.' Clinical adjustments were completed, and postoperative occlusion was verified.
Results:
The restoration exhibited proper occlusal integration and aesthetic blending. Postoperative control confirmed accurate seating and the absence of excess luting material. Maintenance was facilitated by the compressive pontic design. A three-month follow-up revealed excellent functional integration.
Conclusions:
This report outlines the first complete clinical workflow for PC-RBFDPs in posterior regions, providing clinicians with a detailed guide for implementing this minimally invasive treatment in selected cases where implant placement is not indicated.
