Abstract
Objective Dental implant is an effective treatment for tooth replacement, with modern prosthetic materials like lithium disilicate and zirconia enhancing esthetics. However, they are susceptible to peri-implant diseases such as mucositis and peri-implantitis. Poor oral hygiene and bacterial biofilm accumulation are key factors contributing to these conditions. This study aimed to investigate the surface roughness of four different prosthetic materials: lithium disilicate, titanium, polyether ether ketone (PEEK), and zirconia, after being treated with cleaning instruments. Materials and Methods This study was performed on 100 specimens, comprising 25 samples each of lithium disilicate, titanium, PEEK, and zirconia. The surface of the samples was treated with different types of cleaning instruments: piezoelectric ultrasonic scaler (P5 scaler), two air polishing devices (Airflow Classic and Airflow Plus powder), and prophy paste with rubber cup (Prophy paste). Changes of surface roughness and surface topography were measured with a profilometer, and scanning electron microscopy was used for visual analysis. The data was analyzed using the independent-sample Kruskal-Wallis test. Results Compared to the control, the lithium disilicate showed significantly higher roughness when treated with Prophy paste; the titanium showed significantly higher roughness when treated by air polishing (Airflow Classic and Airflow Plus powder), Prophy paste; the PEEK showed significantly higher roughness when treated by air polishing (Airflow Classic and Airflow Plus powder); and zirconia showed significantly higher roughness when treated with the P5 scaler and Airflow Classic. Conclusion It showed that the roughness parameters (Ra and Rz) were affected when treating with various cleaning instruments. From this study, air polishing devices should be used with caution with titanium, PEEK, and zirconia; Prophy paste should be used with caution with titanium and lithium disilicate; and P5 scaler should be used with caution with zirconia. Further studies are required to study the clinical outcomes.
