Disposable dental handpiece

A sterile, substantially maintenance free disposable dental handpiece is constructed from two shells and a center core, the center core having a flow deflector on one end. The shells are joined around the core with mating protrusions and/or tapered walls to form the body and head of the handpiece. A base is integrally-formed with the center core. The base has conduits that allow entry of light and pressurized air and/or water into the body. The head at the opposite end of the body from the base rotatably mounts an impeller assembly having an impeller shaft. The impeller shaft includes blades driven by the pressurized air. The blades can have cavities to reduce weight.

DENTAL HAND INSTRUMENT

Dental curing light having unibody design that acts as a heat sink

A dental curing light includes a device body that efficiently conducts heat away from the light emitting diode portion of the curing light. The device body includes a proximal gripping end and a distal head end. The device body is formed from a thermally conductive body material. Excellent heat conduction away from the LED dies is achieved using a thermally conductive layer disposed over the device body. The thermally conductive layer serves as a conduit to quickly conduct heat away from the LED dies for dissipation within the material of the device body In this manner, the material of the device body serves as a highly efficient heat dissipater. The surface area coupling the thermally conductive layer to the device body is sufficiently large that a majority (e g, substantially all) of heat being conducted by the thermally conductive layer is transferred to the device body during operation of the device.

Hybrid method for dental implant treatment planning

A hybrid method for dental implant treatment planning and a corresponding approach to make a surgical guide. After digital treatment planning is performed with CT scan data, a master model is created, which embodies the patient anatomy and entire treatment plan. Jaw bone, tooth surfaces, soft tissues and nerves are all contained by the master model. The plan details including implant sizes and positions, surgical guide drill options, as well as the choice of a surgical kit, are all conveyed by the master model. Meanwhile, models of specially designed “implant inserts (or replicas)” are also generated, which have one end that fits into the implant holes on the master model and another end to make the surgical guide. The master model and inserts are manufactured with rapid prototyping technology. A surgical guide is later on made from them with conventional lab processes. A main characteristic of this approach is that the master model and the inserts are the physical embodiment of a virtual treatment plan. With them, the surgeons can continue the treatment planning for operations like tooth extractions and bone modifications before making the surgical guides. Therefore the treatment planning workflow is a combination of digital treatment planning and a physical model based planning, in other words, a hybrid approach. A differentiator in this invention is the generation of a closed solid model of the soft tissue, as part of the master model, from the scan data. This approach can be applied to create both bone-borne and tissue-borne surgical guides with low cost process, which is a big advantage over other approaches.
