A dental system including a computer and a display, and one or more dental sensors communicating with the computer. Some of the dental sensors could be operative to provide information or an image of one or more oral components and communicate the image to the computer or computer memory. The image stored in the memory could be a graphic image and the information could also include an image and a predetermined dental treatment protocol. It could be an X-ray image, a two-dimensional image, a three-dimensional image, a panoramic image, and a CT image. This superimposed dental image, received from a number of dental sensors, and the dental instrument image facilitates correction of errors and inaccuracies in instrument location and/or angle of dental instrument positioning and tooth penetration as well as various measurements such as number and length of root canals and other parameters required for performing an accurate dental procedure.

Abrégé

The invention provides a device for monitoring the orientation of a hand-held surgical or dental tool. The device includes one or more orientation sensors that generate signals indicative of an orientation of the device. A processor calculates from the signals a current orientation of the device, where the current orientation is specified by a unit vector defined by a first angle formed between the unit vector and a predetermined first fixed axis and a second angle formed by the unit vector and a second predetermined axis. The processor compares a current orientation of the device with a predetermined reference orientation of the device stored in the memory and provides an indication of the deviation between a current orientation of the device and the reference orientation.

Abrégé

An apparatus for accurate dental implant fixture location determination including an inductive Eddy current effect based dental implant fixture location sensor and a handle. For detection and determination of the dental implant fixture location, the apparatus with the sensor is inserted into a patient mouth and moved in a scanning motion over the gums into which one or more dental implant fixtures have been earlier inserted.
