ABSTRACT:
A method for installing dentures using an implant and an abutment employs a sealing material. The implant has a threaded bore which receives the abutment at a later date. The abutment has a threaded shank and a downward facing shoulder that engages the rim of the implant. Prior to installation, a technician will place a measured amount of bone wax on the abutment shoulder. In another method, the technician places an excess amount of wax and heats the abutment to cause the wax to melt. The technician then screws the abutment into an analog to mold the contour of the wax. The technician then reheats the abutment to cause the wax to reform according to surface tension. The dentist secures the abutment into the implant in a conventional manner.
