Bone resorption at the peripheral edge of the implant can have a major impact on the aesthetic effect, especially when the patient is a smiling line. Titanium and titanium alloy are common materials for manufacturing the oral implant abutment, and the color of the titanium and titanium alloy is silver gray and can be penetrated out from the edge of the gum, so that the gum is green and gray, and the satisfaction degree of a patient is reduced. The titanium surface appears to have a color close to that of teeth in roots and gums and may be an effective method for improving the aesthetic appearance of the neck of the implant.
