Evaluation of Periodontal Pocket Depth around Single Tooth Implant with Cement and Screw-retained Implant Prosthesis

Abstract

This clinical trial was planned to examine the long-standing clinical achievement of dental implants equipped either with cemented or screw-retained systems. A total of 100 teeth were selected based on the following inclusion criteria: should have a particular implant by means of cement and screw implant prosthesis, participants should have superior oral hygiene, non-alcoholic and non-smoker patients, and aged between 20 - 65 years. They were separated into two groups; 50 teeth were cemented (group A) and 50 by a screw (group B) system. At least 24 months evaluation was integrated to measure the periodontal pocket depth. Statistical analysis was done by using SPSS (Statistical Package for Social Science) where comparisons were assess by using the Chi-square test, Fisher's exact test; a P-value <0.05 was considered significant. It was found that at six months, periodontal pocket depth was increased in 2.0% of teeth in Group-A, but none in Group-B. Periodontal pocket depth increased significantly in group A (20%) at 12 months comparing to group B (4.0%). In the same way, at 18 and 24 months, teeth in group-A had significantly higher periodontal pockets (64.0% and 84.0%, respectively) than in group-B (8.0% and 32.0%, respectively). It can be stated that comparing to the cemented implant, the screw implant prosthesis perform better in terms of their periodontal pocket depth.
