Abstract
In some embodiments, the current invention relates to a method and/or system for using a standard dental handpiece for endodontic cleaning. For example, a dental adapter is disclosed having a fitting for a standard dental handpiece, a torque limiter and/or a mount for an endodontic file. For example, the adapter may be single use and/or multi use. In some embodiments, the mount includes the torque limiter. For example, an endodontic file may be connected to the mount with a friction fitting that allows rotation of the file with respect to the mount at high torque. Optionally the mount is positioned eccentrically with respect to the fitting.
Claims14
A system for endodontic procedure comprising:
- an endodontic file including a friction fitting adapted for holding and spinning the file;
- a high torque dental handpiece having a chuck;
- an adapter including:
- a chuck fitting having a proximal portion inside said chuck and held reversibly by said chuck and
- a mount including a cavity having a distal opening with said friction fitting reversibly inserted into said cavity;
- said cavity reversibly holding said friction fitting stationary with respect to the cavity transmitting a transmitted torque to said endodontic file up to a predetermined threshold torque and allowing slippage of said friction fitting in said cavity when said transmitted torque is greater than said threshold torque thereby limiting said transmitted torque between said high torque dental handpiece and said endodontic file to said threshold torque, and
- wherein said chuck fitting of said adapter includes a friction fitting configured to limit said transmitted torque transferred between said handpiece and said adapter.
