Prosthetic Complications in Fixed All-On-Four Prosthesis Reinforced with Poly Ether Ether Ketone (PEEK) Versus Cobalt Chromium (Co-Cr) Framework

Summary

Prosthetic complication will be measured for all-on-four fixed prosthesis in the mandibular arch in completely edentulous patients.

Detailed description

Four implants will be placed in the edentulous mandible following all on four surgical protocol. After 3 months as a healing phase, a definitive prosthesis will be fabricated after ensuring the complete osseointegration of all implants. Provisional restorations will be removed, and final impressions will be taken for each patient using addition silicon impression materials. Framework will be constructed using either Cobalt Chromium (Co-Cr) or Poly Ether Ether Ketone (PEEK) according to the randomization process. Jaw relation and try-in will be done to ensure the correct centric relation. Final prosthesis is then screwed to the abutments and the screw hole channels are closed with composite resin restorations. Occlusal adjustments will be done after the delivery and in the subsequent follow up visit. Prosthetic complications (primary outcome) and biological considerations (secondary outcome) will be measured every 3 months along the follow up period which is one year.
