Abstract: A three-dimensional-based modeling method and system designed for dentistry and related medical (and appropriate non-medical) applications. Data capture means produces a point cloud representing the three-dimensional surface of an object (e.g., dental arch). Three-dimensional recognition objects are provided, particularly within those areas in the image field that have low image definition, and particularly in such of these areas that appear in overlapping portions of at least two images, to provide the three-dimensional image processing software with position, angulation, and orientation information sufficient to enable highly accurate combining (or “stitching”) of adjoining and overlapping images. Alignment, and creation of aligned related objects or models thereof, such as maxillar and mandibular arches, is facilitated.

Abstract: Impression copings used to take an impression of local dentition are attached to a platform. This platform also can include a reinforcing member for stiffening the impression of the local dentition.

Abstract: Fasteners having two or more threaded portions seat impression copings which are used to take an impression of local dentition and related methods. The threaded portions are of a different size.

Abstract: A customized dental abutment is provided which replicates a tooth being replaced. The dimensions of the abutment are determined by a computer algorithm that modifies standard tooth type models according to a series of measurements taken of the site of desired tooth replacement. Methods of the invention relate to talkng a series of measurements of the site of desired tooth replacement, determining the type of tooth being replaced, and preparing or selecting a customized dental abutment based on the measurements and determination. The preparation or selection is made by modifying standard measurements for the type of tooth being replaced in conformity with the measurements taken of the site of desired tooth replacement.

Abstract: An impression coping device for customized implant restorative systems comprises a head having an end for mating with a dental implant fixture. The mating end of the head has a plurality of axially extending, radially resilient fingers for a radial friction fit onto an implanted dental fixture.

Abstract: An impression coping device for customized implant restorative systems comprises a head having an end for mating with a dental implant fixture and a guide stem attached to that head for insertion into a dental implant fixture. The mating end of the head has a plurality of axially extending, radially resilient fingers for a radial friction fit onto an implanted dental fixture.
