Efficacy of a Polyglycol Dimethacrylate-Based Adhesive in Sealing the Implant-Abutment Interface

Abstract

Purpose:The purpose of this study was to assess the effectiveness of a polyglycol dimethacrylate-based adhesive in preventing bacterial leakage through implant-Abutment interfaces (IAIs).Materials and Methods:After implant installation, the adhesive was applied in the experimental group (n = 10). None was applied in the control group (n = 10). Samples were collected from the inner walls of implants on days 0 and 90. The real-Time polymerase chain reaction was used to detect bacterial DNA.Results:All samples from the control group, versus 30% from the experimental group, harbored bacterial DNA on day 90.Conclusions:This polyglycol dimethacrylate-based adhesive may be used to seal the IAI. Further studies are warranted to verify its effectiveness over longer time periods.
