Clinical Assessment of All Ceramic Single-retainer Using Upper Canine as Abutment With Minimum Preparation on the Lingual Surface, to Replace the Upper Lateral Incisor and Will be Compared With the All Ceramic Single-retainer Using Upper Central Incisor.

Overview

The Intervention Will be All Ceramic Single-retainer Resin Bonded Fixed Partial Denture Using the Upper Canine as Abutment With Minimum Preparation on the Lingual Surface Within the Enamel Providing Maximum Area for the Retainer Bonding, to Replace the Upper Lateral Incisor and Will be Compared With the Control/Comparator Group Which is the All Ceramic Single-retainer RBFPD Using the Upper Central Incisor. The Participants in This Study Will be Recruited by the Researcher From the Clinic of Fixed Prosthodontics Department, Clinic of Orthodontics Department and Clinic of Diagnosis Department, Cairo University Without Any Financial or Non-financial Incentives.

The intervention will be all ceramic single-retainer Resin Bonded Fixed Partial Denture using the upper canine as abutment with minimum preparation on the lingual surface within the enamel providing maximum area for the retainer bonding, to replace the upper lateral incisor and will be compared with the control/comparator group which is the all ceramic single-retainer RBFPD using the upper central incisor. This intervention will be done by one investigator in all study groups who has master degree in fixed prosthodontics with eight years of experience. The intervention will be carried out in the clinic of the department of Fixed Prosthodontics, Cairo University under supervision of PhD holder staff members. The self-adhesive dual cure resin cement will be used for cementation in all groups. In the first session, the participant will be informed about all steps from the beginning to the end. All participants will be encouraged to maintain good oral hygiene and attend the regular follow up visits and in case of any complain related to the investigated restoration.
