Evaluation of the Effect of PEEK Versus Co-Cr Digital Telescopic Mandibular Partial Denture on Patient Satisfaction and the Supporting Structure

Краткое описание

This study evaluates and compares the clinical performance, retention, and patient satisfaction between Polyetheretherketone (PEEK) and Cobalt-Chromium (Co-Cr) digital telescopic mandibular removable partial dentures. Patients requiring mandibular telescopic removable partial dentures receive digitally fabricated prostheses to assess retention, abutment tooth preservation, periodontal indices, and patient satisfaction over a 12-month follow-up period.
