ABSTRACT:
An improved surgical implant, including dental implants, formed of Ti and its alloys and a process of its manufacture are disclosed. The improved surgical implant is designed to withstand fretting wear and abrasion occasioned by vibrating micromotion of the implant against the surrounding bone structure. Such micromotion has caused undesirable blackening in the surrounding tissue and has required premature replacement of the implant.
