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.

Interventions

Type	Name	Description
PROCEDURE	CAD PEEK frame-work	Construction of PEEK framework will be done conventionally by lost wax technique using a vacuum press device. The wax pattern will be invested in a mold using special investment. Then it will be heated and melted to produce a mold into which PEEK will be vacuum pressed. The framework will be fitted on the master cast
