Title:
HYBRID PRESS FIT-THREADED DENTAL IMPLANT
Document Type and Number:
WIPO Patent Application WO2001037758
Kind Code:
A3
Abstract:
A dental implant (10) has a body (12) with a press fit diameter fit into a hole drilled into a patient's jaw bone, and having a helical groove (14) machined into the body diameter to improve the rate of growth of bone tissue thereinto to securely lock the implant (10) in position. A shallow height oppositely wound helical thread (32) may be added to increase the holding force upon initial fitting of the implant (10). The shallow height and long pitch of the thread (32) produces only minimal stress of the surrounding bone tissue to insure long term retention.
