ABSTRACT:
A Quick Release Adjustable Dental Band Clamp is intended to rigidly fix orthodontic attachments to a tooth. There are two major advantages to this invention. First, the band clamp can be compressed to a near-size fit by finger pressure, thereby, reducing operator time with the hand tool. Second, the clamp provides a quick release of tension, enabling fast removal. The clamp is a flexible metal strip with two free ends. One end contains a permanently fixed joining mechanism which is the heart of the invention. The other end is designed to be pulled by a joining mechanism into a created holes interior. The joining mechanism has two main operative parts: a worm and a locking pin. The worm draws the band material tightly and is governed by the locking pin, which is either engaged or disengaged with worm. When the locking pin is engaged with the worm only tightening is permitted. Loosening is allowed when the locking pin is disengaged.
