Abstract
Abstract An absorbable mesh material useful as a dental implant. The mesh is cut by lasers to afford smooth edges which will not unravel. The implant may be attached by a ligature or suture material, generally formed from the same material as the implant, and attached to the implant by, among other things, laser or ultrasonic welding or interweaving.
