Effects of Different Prophylaxis Procedures on Titanium Implant Fixture: A Scanning Electron Microscopy Study

摘要

This study aimed to describe the effects of different prophylaxis procedures on titanium implant fixture surfaces under Scanning Electron Microscopy (SEM). Fifteen BEGO Semados庐 implant fixtures were mounted on stone stands and randomly divided into 3 groups which were Control (C) (n=5), Air Flow (AF) (n=5) and Rubber Cup with Pumice Powder (RC) respectively. After 2 minutes of prophylaxis procedures, all treated samples were irrigated with normal saline and fixed with 2.5% glutaraldehyde. They were air dried, wrapped and stored in individually labeled and sealed compartments. One fixture was randomly selected from each group and they were observed under SEM at x1000 and x2000 magnifications. SEM showed that surfaces from C group displayed machine lines due to milling process with minimal pits and scratches. The surfaces from AF group had generalized micro pits and pores with the machine lines still observed. In RC group, the surfaces demonstrated homogeneous line of scratches that identical to the rotational movement of the RC. The machining marks and lines were also disappeared. Based on the findings, the titanium implant fixture surfaces treated with RC revealed less invasive and more effective compared to AF.
