Rehabilitation of one-piece screw-retained implant crowns placed at second-stage surgery-a retrospective patient series.

Objectives: To evaluate the esthetic and functional rehabilitation of single implants delivering the final crown during second-stage surgery.

Materials And Methods: In 26 single-tooth implants, the impressions were taken immediately after implant placement to fabricate the final crowns. During the second-stage surgery, the screw-retained hybrid crowns were delivered.

Accuracy of a robotic system for the reproduction of condylar movements: a preliminary report.

Objective: Methods in restorative dentistry have to meet stringent accuracy requirements. The accuracy of robotic systems used for the reproduction of condylar movements has not been determined. The purpose of this study was to assess the accuracy of the robot system, ROSY, a robotlike electronic simulator (developed by the author) that reproduces condylar movements previously recorded on a patient.
