No results posted yet for this study

Summary

The importance of this trial lies in testing if intraoral digital impressions will increase the accuracy of impressions of full arch implant cases over conventional impression techniques thus improving the passivity of full arch screw retained prosthesis and decreasing the prosthetic complications in turn.

Conditions

  • Passivity
  • Prosthetic Complications

Interventions

DEVICE

Digital impression technique

3D printed generic Scan bodies with unified shape and length replacing the traditional transfer copings will be press fitted on the trans-mucosal abutments and pickup cylinders that are screwed on the implants to capture their position and intra-oral scanning will be done.

OTHER

Open tray impression technique

Transfer copings will be screwed to the multiunit abutments on the existing implants, and splinted together using pre-cured printed resin splinting framework that will be fixed to the copings using flowable composite . A one step impression technique using putty and light addition silicon will be made, where light impression material will be injected all around transfer copings and putty silicon will be loaded in tray and then will be seated intra-orally making sure to fully expose the screws of transfer copings through the impression material.
