Brief Summary

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

Conditions

Retention

Outcome Measures

Primary Outcomes (1)

• retention

  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

  3 months

Study Arms (2)

CAD PEEK frame-work

EXPERIMENTAL

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

Procedure: CAD PEEK frame-work

CAD metallic frame-work

ACTIVE COMPARATOR

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.

Procedure: CAD PEEK frame-work
