| 20110223559 | DENTAL HANDPIECE SYSTEM WITH REPLACEABLE TREATMENT TIPS - A dental hand piece with replaceable tips at either end of a tubular handle, each of the replaceable tips including a tip assembly having an instrument working tip end at a distal end of a main tip body and a shank extending from the instrument working tip end to a proximal end of the main tip body. The tip assembly may be provided with a flat-blade extension end at the proximal end of the main tip body. The flat-blade extension end passes through a keyway-shaped slot provided in a locking component, and engages locking structure provided on a cylindrical barrel member. Replaceable tips at the ends of the tubular handle may be secured in 180° orientation to one another. A spring arm member may additionally or alternatively engage notches along an interior wall of the cylindrical barrel member. | 09-15-2011 |
| 20110177474 | Handpiece for a Magnetostrictive Power Generator - A magneto strictive sterilizable handpiece ( | 07-21-2011 |
| 20110143304 | Adaptor for Lighted Dental Device - Embodiments of an adaptor for a lighted magnetostrictive device, a lighting system for a hand-held dental delivery device including an adaptor, and a method of providing light at a magnetostrictive hand-held device using an adaptor are disclosed. The adaptor may securely connect to a hand-piece of the device, and may include a self-contained electric power storage device to power a light source, an adaptor light channel for delivering light from a light source to the insert, or both. The light source may be disposed within the hand-piece, the adaptor or the insert. A user may switch the light source on and off, and/or may dim or brighten an intensity of the light. The light source may provide illumination even when a tip of the device is not activated, and the electric power storage device may be inductively re-charged. | 06-16-2011 |
| 20110140815 | Integrated, Lighted Ultrasonic Inserts - Embodiments of a magnetostrictive device, a dental lighting system, a method of illuminating a lighting apparatus and a lighting apparatus are disclosed. The embodiments may include a lighting apparatus with a light source, an electrical power storage device and a switch. When the switch detects a magnetic field, the switch may complete an electrical connection between the electrical power storage device and the switch, thus illuminating the light source. The magnetic field may be magnetostrictively or non-magnetostrictively generated, and maybe be produced by a receptacle, a hand-piece or the lighting apparatus itself. A user may switch the light source on and off. In a magnetostrictive device, the light may be illuminated even when a tip is not activated, and the electrical power storage device may be inductively re-charged. The lighting apparatus may be included in an insert of a magnetostrictive device, such as a magnetostrictive ultrasonic hand-held dental device. | 06-16-2011 |
