A surgical drill type cutting tool includes a shank and an active portion extending in the extension of the shank, with chip areas extending along the active portion, and a ring surrounding a part of the active portion, an inner surface of the ring engaging the active portion without closing off the chip areas, allowing irrigation fluid to provides useful irrigation over most of the length of the active portion of the surgical drill bit.

The high-speed turbine dental handpiece adapted for single safe use comprises a nose, a handle connected to the rear end of the nose, a plug connector disposed at the rear end of the handle, and a clip ring for fixing the handle and the plug connector, wherein the plug connector is provided with a first fixing slot at a side wall, the tail end of the handle is provided with a second fixing slot matched with the first fixing slot, the inner wall of the clip ring is provided with bumps matched with the first fixing slot and the second fixing slot, and when the clip ring is hooped on the plug connector, the bumps are embedded into the first fixing slot and the second fixing slot to limit and fix the handle and the plug connector. The invention effectively prevents the disposable dental handpiece from being reused in various ways, it is simple in structure and convenient to detach and thus can be conveniently detached and destroyed after being used, and in addition, with the disposable light-emitting component, whether the dental handpiece is used can be identified simply and clearly. According to the inventor, the concept of one handpiece for one patient for single use as advocated by the WHO in the field of oral health can be achieved, effectively solving the problem of iatrogenic cross infection in the field of stomatology. The invention is similar to a disposable syringe but with a more complex structure as a dental handpiece.

The invention relates to a dental tool having a shank region, which is formed for coupling to a dental handpiece, and also having a work region, which is connected to the shank region. In this case, the shank region of the dental tool is formed so that there is the possibility of latchable insertion and removal without actuation. In particular, at least the shank region can consist of plastics material. As a result, inter alia facilitated handling of the tool and inexpensive production of the tool are rendered possible.

A snap-on snap-off drill stop device for boring into a tooth and or in bone. The stop device that impedes insertion of the bore device into the tooth or bone tissue beyond predetermined depths at pre-selected stages of a drilling process by simplifying the tedious process of exchanging drill bits and drill stops for the ultimate size and depth bore.

An orthodontic system and method for moving and aligning at least one tooth of a set of teeth of at least one of an upper jaw and a lower jaw of a patient. In the system and method an orthodontic appliance can be provided which may include a force exerting member for applying a force to and moving the at least one tooth, a tooth movement sensor member for obtaining at least one of tooth movement data, tooth position data, and tooth identification data, and a tooth movement monitor for calculating at least one of an amount of tooth movement and tooth position from the at least one of the tooth movement data, the tooth position data, and the tooth identification data obtained with the tooth movement sensor arrangement. An electronic control console may be operatively connected to the force exerting member and in data communication with the tooth movement monitor, for controlling the operation of the force exerting member based on the at least one of the tooth movement data, the tooth position data, and the tooth identification data received from the tooth movement monitor.
