Abstract
Implants with hydrophilic surfaces have been to better maintain surface integrity compared to hydrophobic surfaces. This underscores the importance of surface hydrophilicity in enhancing implant stability during the osseointegration period, especially in challenging bone conditions. Despite the benefits associated with hydrophilic surfaces, it is essential to understand the limitations and optimal methods for achieving and maintaining surface hydrophilicity. This study aims to spectroscopically differentiate the aqueous substances used by Straumann® and assess variations in surface wettability of dry Singular® implants before and after immersion in the aqueous substance. Material and Methods: Dental implant samples were divided into two groups: Group 1 (n=6) comprised SLActive Straumann® implants, commercialized in an aqueous medium, and Group 2 (n=4) consisted of dry Singular® implants. Wettability evaluations were conducted initially, followed by immersion of dry implants in the aqueous solution of SLActive Straumann® implants. After 180 days, samples were reevaluated to observe changes in surface wettability, the analysis was employed to analyze the aqueous substance. Wettability analysis was performed using the contact angle technique. Data analysis involved tabulation and application of the Shapiro Wilk test for normality verification, followed by paired t-tests for wettability analysis. Spectroscopic analysis revealed significant similarities among the samples, with characteristic peaks indicating the presence of water molecules. Contact angle measurements indicated a statistically significant reduction after immersion in the aqueous medium, transitioning the surface from hydrophobic to hydrophilic. Most analyzed samples exhibited high water concentrations, indicating the presence of water as the primary component. The saline solution showed potential for improving osseointegration by reducing contact angles, suggesting enhanced wettability. Classification of surface wettability indicated a shift from hydrophobic to hydrophilic after immersion in the aqueous medium, aligning with previous studies on SLActive surfaces. Our study demonstrates that immersion in an aqueous medium alters implant surface wettability, regardless of surface treatment.
