A bone expander contains: a body including a limitation section formed on an upper end of the body, a drill tip formed on a lower end of the body and extending from a bottom of the limitation section, a defining shoulder formed in an expanding umbrella shape and between the bottom of the limitation section and the drill tip, and multiple spiral ribs formed on the drill tip and the limitation section. The drill tip has multiple chip delivery grooves, and a respective chip delivery groove is defined between the drill tip and a respective spiral rib. The limitation section has multiple guide flutes corresponding to the drill tip and extending from the multiple chip delivery grooves, the drill tip has a cutting portion extending from a distal end thereof, and the cutting portion has a conical face formed thereon.

A dental prophylaxis and air appliance having a pressurized air source, a hand piece, and a manually actuated slurry container containing a mixture of dry or wetted abrasive and non-abrasive components. The compressed air is delivered to the hand piece by a line that combines the compressed air with the components and discharges the post-mixed water slurry of abrasive or non-abrasive components. The hand piece is configured to include a series of valves adapted to define one or more stages for containing components and encourage mixing thereof during operation.

A method including fixing a dental drill template with a fixation pin including a rod and a head attached to the rod. The dental drill template can be fixed by inserting the rod into the drill template or a sleeve provided in the drill template such that a bearing surface of the head bears at least partially on the drill template. The rod has a shape of an essentially circular cylinder and extends from the bearing surface of the head at an essentially right angle. A diameter of the head at the bearing surface is larger than the diameter of the rod.

A dental implant whereby an osteotomy cavity is formed in jawbone and then a base member of the implant is positioned into the cavity. The base member serves as a platform to secure an abutment member of the implant that in turn receives a dental restoration, such as a crown or denture.

A fixation pin for fixing a dental drill template. The fixation pin has a head having a bearing surface that is intended to bear at least partially on the drill template, or a sleeve provided in the drill template. The fixation pin has a rod having a shape of an essentially circular cylinder and extending from the bearing surface at an essentially right angle. The rod is intended to be inserted into the drill template or the sleeve provided in the drill template.

A dental light device which has a light output for providing blue light, and an air outlet arranged adjacent the light output. The air outlet is connected or connectable to an air supply. The dental light device provides for simultaneously irradiating an object and cooling the object.

A dental matrix according to the present invention comprises (a) a metal matrix band comprising an internal surface and an external surface; and (b) an organic light emitting diode (OLED) layer disposed on at least a first portion of the internal surface of the metal matrix band, the OLED layer comprising a first electroluminescent polymer disposed between a first and a second electrode layer. Applying an electrical current across the OLED generates light energy suitable for curing dental restoration material with the light energy being applied from the interproximal space.

Apparatus and method for installing a multi-tooth dental prosthesis in one session are shown and described. A first tool attaches to the jawbone, and serves as a foundation for subsequently used guides. Existing teeth and dental fixtures are removed, and the bone tissue is removed to accommodate the prosthesis. Subsequently, a drill guide is used to drill implant holes. An abutment guide is then used to place abutments. Copings are then installed. Next, the prosthesis may be installed and cemented to the copings. A resinous filler material may be applied to fill gaps and holes in and between the copings and the prosthesis, and is sanded smooth.

A system is disclosed. The system contains an instrument configured to fit in a patient's anatomy, an optical sensor associated with the instrument, a processing unit receiving data from the optical sensor, and a display displaying position of the instrument in the patient's anatomy based on the data from the optical sensor.

In one embodiment, a light guide includes an emitter and a light guide body optically coupled to the emitter. The light guide body may define a cylindrical body that tapers along an angled plane from a top end towards a bottom end. The bottom end may define a light entrance to the light guide body.
