Lock washer for dental implant-supported restorations

A lock washer connection is added to a current screw used in dental implant practice.

Project Overview

Dr. Tipple uses the implant placement technique called the screwmentable. This technique allows the abutment and crown to be screwed directly into the implant through a passageway in the crown. This allows Dr. Tipple to adjust the crown as needed checking lateral, left and right occlusions and clench tests before the passageway is filled and sealed. The screw holding the abutment to the implant can become loose through everyday occlusal forces such as chewing. Adding a lock washer to the screw would sustain the 35 Ncm torque that is applied to the screw when placed in the implant. The lock washer is able to apply spring tension to keep the screw from loosening.
