Clinical Step-By-Step Approach for Posterior Cantilevered Single- Retainer All-Ceramic Resin-Bonded Fixed Dental...

Area of Science:

• Dental Prosthodontics
• Minimally Invasive Dentistry
• All-Ceramic Restorations

Background:

• Missing mandibular molars present treatment challenges.
• Implant therapy may not be suitable for all patients.
• All-ceramic resin-bonded fixed dental prostheses (PC-RBFDPs) offer a conservative alternative.

Purpose of the Study:

• To describe a detailed step-by-step protocol for fabricating and adhesively luting posterior cantilevered single-retainer all-ceramic resin-bonded fixed dental prostheses (PC-RBFDPs).
• To provide clinicians with a guide for implementing this minimally invasive treatment in selected cases.

Main Methods:

• Fabrication of a 3Y-TZP zirconia PC-RBFDP with feldspathic buccal veneer and compressive pontic.
• Minimal enamel preparation and intraoral sandblasting with aluminum oxide.
• Adhesive luting using preheated resin composite and a strictly light-cured protocol ('no-finishing concept').

Main Results:

• Successful fabrication and adhesive luting of the PC-RBFDP.
• Restoration exhibited proper occlusal integration and aesthetic blending.
• Three-month follow-up showed excellent functional integration and ease of maintenance.

Conclusions:

• This report presents the first comprehensive clinical workflow for posterior PC-RBFDPs.
• The described protocol offers a detailed guide for clinicians.
• PC-RBFDPs are a viable, minimally invasive treatment option for posterior tooth replacement when implants are not indicated.
