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.
Claims19
A system for use of a dental handpiece for an endodontic procedure comprising:
- an endodontic file including a friction fitting adapted for holding and spinning the file;
- an adapter including:
- a chuck fitting having a proximal portion configured to be reversibly held inside a chuck of said dental handpiece;
- and
- a mount including a cavity having a distal opening, said cavity configured for reversibly holding the friction fitting of the endodontic file
- and for transmitting a transmitted torque to said endodontic file and for allowing slippage between said cavity and the friction fitting of endodontic file when said transmitted torque is greater than a predetermined threshold torque thereby limiting said transmitted torque between said dental handpiece and said endodontic file to said threshold torque, wherein said cavity is fixed in position with regard to said chuck fitting and an axis of said cavity is offset in relation to an axis of said chuck fitting.
A system for use of a dental handpiece for an endodontic procedure comprising:
- an endodontic file including a friction fitting adapted for holding and spinning the file;
- an adapter including:
- a chuck fitting having a proximal portion configured to be reversibly held inside a chuck of said dental handpiece;
- and
- a mount including a cavity having a distal opening;
- said cavity configured for reversibly holding the friction fitting of the endodontic file and for transmitting a transmitted torque to said endodontic file and for allowing slippage between said cavity and the friction fitting of endodontic file when said transmitted torque is greater than a predetermined threshold torque thereby limiting said transmitted torque between said dental handpiece and said endodontic file to said threshold torgue, wherein said cavity is positioned eccentrically with respect to said chuck fitting such that rotating of said chuck fitting around an axis thereof by said handpeces rotates said endodontic file around said axis on a path that is eccentric to an acis of the file.
A system for performing an endodontic procedure using a high torque dental handpiece having a chuck comprising:
- an endodontic file including a friction fitting adapted for holding and spinning the file;
- an adapter including:
- a chuck fitting having a proximal portion configured to be 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 wherein said cavity is fixed in position with regard with said chuck fitting and an axis of said cavity is eccentric in relation to an axis of said chuck fitting.
