简要总结

Patients with missing back teeth can be restored with an inlay retained bridge.The inlay retained bridge designs include inlay shaped, tub shaped or proximal box shaped.In this study a clinical evaluation will be commenced to evaluate two designs the inlay shaped and the tub shaped.The hypothesis of our trial is that the new design may show longer survival rate due to less stress applied on the restoration which allow the restoration to function for longer period as the inlay shaped bridge showed clinical problems during survice.

详细描述

: This trial will be conducted on patients from the Outpatient clinic in the Fixed Prosthodontics Clinic, Faculty of Oral and Dental Medicine, Cairo University.

  • Adherence session will take place in the presence of the patients in the initial visit. This include that the patient will be informed by Abdelfattah M about the study steps and maintenance of oral hygiene instructions. Participants will be asked by Abdelfattah M about if they have any problems like pain.

Motivation and enforcing the maintenance of oral hygiene measures by Abdelfattah M.

The visits will be designated as follows:

Visit 1: Preoperative records, face-to-face adherence reminder session, clinical examination, radiographic examination, intraoral photography and primary impressions (Zhermack ) for diagnostic cast construction ( Zhermack ) . Visit 2: teeth preparations, secondary impression ( Zhermack ) and temporization (Tempofit) .
