Passive Fit of CAD/CAM Screw-retained Metal Frameworks Versus Screwmented Ones

NCT04372901 · Status: UNKNOWN · Phase: NA · Type: INTERVENTIONAL · Enrollment: 8

No results posted yet for this study

Summary

CAD/CAM (computer aided design/ computer aided manufacturing) constructed screw retained implant supported frameworks give solutions for the problems arising from the lost wax technique by improving accuracy, adaptation and passive fit of the final restoration. However, concerns about the passive fit of a pre-implant insertion CAD/CAM constructed framework still exists due to the expected errors in imaging, registration, surgical guide construction, adaptation and hence transferring the planned position intra-orally.

Conditions

  • Edentulous
  • Jaw

Interventions

PROCEDURE

Digitally constructed frameworks before implant placement

Intervention group in which the edentulous area will be restored with 3-implant screwmented CAD/CAM frameworks constructed based on planned implant positions.

PROCEDURE

Digitally constructed frameworks after implant placement

Control group: edentulous area will be restored with 3-implant conventional screw retained CAD/CAM frameworks constructed after implant placement.
