Rate of marginal bone loss around screw–retained and cement retained single implant prostheses – a split mouth study

Dr. Litty Francis, Dr. S. Babukuttan Pillai

Abstract :

Implant supported restorations have become an integral part of main contemporary dental care. The prostheses can be attached to implants with screws or can be cemented

Aim and Objective:

To compare and evaluate rate of marginal bone loss around 30 implant supported screw–retained and cement–retained prostheses for a period of 12 months in a split mouth design

Material and methodology:

The sample consists of 30 single tooth implant restorations, placed bilaterally; one on either side of the arch; in 15 patients. The mean age of the sample was 29.4+–8.17 years. The sample was divided in to two groups screw–retained (Group I) or cement–retained (Group II) and were evaluated radiographically for rate of marginal bone loss for a period of twelve months.

Results:

The cement –retained implant supported prosthesis had shown significantly (p>0.05) more rapid marginal bone loss.
