Stability And Survival Rates Of A Hydrophilic Versus A Conventional Sandblast,acid-etched Implant Surface

Background: Modifying the implant surface by enhancing the wettability(hydrophilicity)improves osseointegration,thus reducing the healing period.In this study,the authors aimed to evaluate the stability and survival rates of implants with a hydrophilic surface compared to those with a sandblasted and acid-etched surface.Types of studies reviewed: The included studied(randomized controlled trials RCTs)were identified by searching the PubMed,ScienceDirect,and Cochrane library databases without date of publication restrictions.Quality assessment was performed using the Cochrane Collaboration’s tool.For the primary outcome,confidence intervals were set at 95%;weighted means across the studies were calculated using a fixed-effects model or using risk ratios and their 95% confidence intervals for the secondary outcome.Results: The authors included 5 RCTs(246 dental implants)in the systematic review which compared a hydrophilic with conventional sandblast and acid-etched implant surface.The implant stability(primary outcome)was measured at baseline and 3,6,and 8 weeks,and the implant survival rates were measured as a secondary outcome.Overall,compared with the control groups,no clinically significant differences in implant stability or survival rates were identified for the hydrophilic surface groups.Conclusions: results didn’t show any clinically significant effect of a hydrophilic surface on improving implant stability or survival rates.However,these findings must be analyzed carefully due to the limitations of this review,such as the small sample size and some differences among the included studies.
