Summary

The aim of this study is to assess the effect of the newly introduced (hybrid dental ceramic) superstructure materials, Vita Enamic versus IPS Emax on implant stability, patient satisfaction and crestal bone loss.

Detailed description

This study will be conducted on patients requiring single implant replacement in the maxillary premolar area, admitted to the Outpatient Clinic of Fixed Prosthodontics Department, Faculty of Oral and Dental medicine, Cairo University. After a period of healing of 6 months, an implant abutment of accurate diameter and angulation will be placed to fit precisely into the internal hex of the fixture after removal of the cover screw. The platform matched abutment will be then secured into its final position using the abutment screw. Alginate impression will be taken and poured into dental stone. Using the impression transfers, impressions with polyvinylsiloxane are taken. After taking the impressions, the Impression transfers are removed and fixed to the implant replica. Surgeons' assistants will be asked to open the sealed envelope containing the information regarding the crown placement. The impressions will be sent to dental laboratory with the result of the sealed envelope, for preparation of the future crowns, either vita enamic crowns or Ips e max crowns.
