- Abstract
Objective: This study aims at carrying out a descriptive comparative analysis of four types of surfaces of commercially pure titanium implants by means of scanning electron microscopy (SEM). Material and Methods: Four implants of different commercial brands were used, as follows: Conexão - Sistemas de Próteses (Prosthesis system) and Straumann. The samples had their surfaces machined by means of acid etching, anodization (Conexão) and blasting followed by acid etching (Straumann) techniques, and were divided into four groups with one implant each. The areas of thread top and valley were determined for SEM analysis at different magnifications. Results: All samples assessed presented characteristics of surface rugosity, including the machined surfaces. The implants treated by anodization and blasting followed by acid etching had a greater surface pattern in comparison to the implants treated by acid etching due to their greater degree of rugosity. Conclusion: Surface treatment influences surface macro structure. Surfaces treated by anodization and blasting followed by acid etching presented a surface pattern that provides a greater area for bone apposition.
