摘要 |
The invention is an improved endodontic apparatus device for holding instruments, particularly endodontic drill files that are energized and vibrated by ultrasonic means. The invention also provides for the flow-through of solutions during debriding and irrigating of root canals. The invention consists of a hollow tube-like means for conducting solution and directing it in the axial direction of the endodontic drill file; the hollow tube-like means incorporates a special holding means at the outboard end thereof for mounting the drill file in a position so that ultrasonic waves can be transmitted to the drill file to cause it to vibrate in a manner that improves debriding of the root canals. The special holding means at the end of the hollow tube-like means retains the drill file in a firm position to receive the transmitted ultrasonic waves.
