Intraoral vs Extraoral Cementation of Zirconia Bridges on Ti-Bases: Microstrain Evaluation

Sponsor: Universitat Internacional de Catalunya

Summary

This prospective clinical study compares two cementation techniques for implant-supported zirconia fixed partial dentures on titanium bases (Ti-bases): extraoral cementation performed on the working model and intraoral cementation performed chairside. Thirty clinical cases with two osseointegrated implants requiring a multi-unit zirconia restoration will be recruited at the UIC Dental Clinic. For each case, two restorations with identical design will be produced: one will be cemented extraorally (control) and an identical replica will be cemented intraorally (test). Micro-deformation will be assessed as peri-implant microstrain (µε) using a standardized strain-gauge setup and the same recording protocol for both techniques. The primary analysis compares microstrain between intraoral and extraoral cementation within each case; implant/prosthetic events will be recorded descriptively.
