简要总结
comparing retention of CAD CAM metallic and Poly Ether Ether Ketone (PEEK) partial dentures in Kennedy class I casses
详细描述
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.

研究组 & 干预措施
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
干预措施: CAD PEEK frame-work (Procedure)
CAD metallic frame-work
A metallic framework will be obtained using the conventional lost wax technique and casting. After de-investing, finishing and polishing, the framework will be fitted on the master cast. Intraoral try in of the framework will be done followed by bite registration record. The next step will be teeth setting and try in. Heat cured acrylic resin denture base will be processed, finished and polished conventionally. The finished removable partial denture will then be checked intraorally for any needed modifications and finally delivered.

时间窗: 3 months
Measurements are performed for each RPD at the time of denture insertion, after one month and three months later. Measurements were carried out using digital force gauge which is an advanced type of force meter device, used to measure tension or compression up to 20 Kg
