Abstract: A device and method is presented for enhancing the shape, mass, and strength of alveolar and intramembranous bone, primarily in areas of bony deficit. In one embodiment, the device is made up of a hollow body which forms a housing to contain a drive train and provide a surface for attaching mounting elements. A worm gear activating element which meshes with a threaded lead screw acts as the drive train. A carrier is coupled by threads to the lead screw. As the worm gear is turned, the lead screw rotates and causes the carrier to move along the axis of rotation of the lead screw. In this embodiment, the soft tissue in a region of tooth loss is reflected to expose the atrophic bone site. A piece of bone harvested from the exposed area or other bone attractant material is attached to the carrier. The soft tissue is adapted over the carrier and sutured, and the assembly is attached to available dental structures.

Abstract: Computer control apparatus uses sensing apparatus converts a mechanical movement into a direct current electrical signal. An electrical interface circuit is connected to the sensing apparatus for converting the direct current electrical signal into a pulse output used in controlling a computer. The preferred sensor is an inclinometer, which comprises an opaque body having a chamber. A light source is connected to the body to provide light in the chamber. Photocell apparatus is connected to the body to receive light emitted from the light source for providing an electrical resistance in relation to the amount of light received. Supported in the chamber is a liquid filter medium to absorb light emitted from the light source. A sufficient quantity of liquid filter medium is provided in the chamber to prevent light emitted from the light source from impinging upon the photocell apparatus in response to the angular placement of the body with respect to gravity.
