Official Title: The Effect of Lithium Disilicate Glass-ceramic (IPS Emax) Versus Hybrid Ceramic (Vita Enamic) Superstructure Materials on Implant Stability in Implant Supported Restorations

Brief 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 Summary:

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.

Current Primary Outcome: Implant survival rate [ Time Frame: 12 months ]

Implant stability and success could be affected by crestal bone loss, if the implant is stable therefore high survival rate


Original Primary Outcome: Same as current

Current Secondary Outcome:

  • Crestal bone loss [ Time Frame: 12 months ]
    Crestal bone loss will be measured using a Cone Beam Computed tomography to measure the amount of bone resorbed from start date, and follow up for one year
  • Peri-implant tissue response [ Time Frame: 12 months ]
    Bleeding index, probing depth and gingival index
  • Patient satisfaction [ Time Frame: 12 months ]
    Patients will be asked to answer a questionnaire to know whether the procedure was not satisfied, accepted, or highly satisfied


Original Secondary Outcome: Same as current
