ABSTRACT:
A self-tapping dental implant includes a body which is substantially covered by a random surface roughening without adversely affecting the cutting edge and thus the amount of torque needed to thread the implant into bone tissue. During the surface treatment process, the cutting edges of the implant are covered with a removable shield. The shield may engage the implant through openings on either side of the cutting edge. The shield is adaptable for use with implants having multiple cutting edges since the shield may include a plurality of arms connected by a base. The shield may be snapped onto the distal end of the implant.
