Stability, Marginal Bone Loss and Occlusal Load Analysis of PEEK Abutment Supported on Short Implant

Faculty of Dental Medicine for Girls12 enrolled

Overview

this study will be directed toward evaluating stability, marginal bone loss and occlusal load of posterior customized PEEK abutments on Ti-bases supported by short implant

although short implant solved many clinical problems; it is sometimes associated with loss of osseointegration which is firstly expressed by peri-implantitis and marginal bone loss. Also, PEEK is a very promising material characterized by low modulus of elasticity thus it can act as a shock absorber. Whether constructing superstructure components of short implant from PEEK will improve their performance or not is lacking in the dental literature. To conduct the present study, the following will be used: 1. Customized screw retained PEEK abutment/crown on a Ti base. 2. Prefabricated titanium abutment. 3. Short implant. The study will be conducted on 12 patients with missing single posterior tooth indicated for short implants) near anatomical structure or atrophic ridge), attending the outpatient clinic of the Crowns and Bridges department, Faculty of Dental Medicine for Girls, Al-Azhar University.
