• Lead Sponsor: Cairo University

Brief Summary

comparing retention of CAD CAM metallic and Poly Ether Ether Ketone (PEEK) partial dentures in Kennedy class I casses

Detailed Description

partially edentulous patients with Kennedy class I classification will be recruited for the trial and then randomly distributed on two groups; experimental group will receive CAD CAM PEEK partial denture and control group will receive CAD CAM metallic partial denture. then primary impressions will be made and then mouth preparation followed by secondary impression then scanning of the master cast using extra-oral scanner then designing the partial denture using blender for dental then the frame work will be printed.

then frame work will be processed into either PEEK or Metal according to randomization.

retention will be measured at zero and 3 months.
