Summary

The purpose of this study was to assess the effect of Bio-Hpp versus Co-Cr custom abutments in fixed-detachable implant-supported mandibular partial dentures clinically and radiographically in Class I Kennedy classification (split-mouth study)

Detailed description

Participants with bilateral partial edentulism in the posterior mandible received two implants at the positions of the second premolar and second molar on both sides; one side was restored with BioHpp based screw-retained FDP (test group) and the other side was restored with Co-Cr based screw-retained FDP (control group). All patients were clinically examined at the time of prosthesis insertion, and 6,12 months later for fracture of implant or framework, fracture, or looseness of the screw, veneer chipping, and fractures, modified bleeding index, modified plaque index, peri-implant probing depth, as well as radiographically for marginal bone loss

Conditions

• Edentulous Alveolar Ridge
