摘要:
A method, device and system for modifying the gingival margin of a patient is disclosed. A method includes obtaining an electronic model of the dentition of a patient, determining an incision path along the gingival surface based on the electronic model, generating and fabricating a guide arrangement to assist in cutting the gingival surface of the patient, mounting the guide arrangement to the dentition of the patient, and cutting the gingival surface of the patient with the assistance of the guide arrangement. A guide arrangement includes a mounting portion and a template portion coupled to the mounting portion along the gingival surface of the guide arrangement and positioned to provide a desired incision path. A system includes a three dimensional scanner, a computer system and a fabricating device.
摘要:
By matching a first data set including digital, three-dimensional, dental models with a second data set including digital, cranio-facial 3D medical scan records, missing or inaccurate portions of the cranio-facial 3D medical scan record can be improved. Example methods for matching the data sets include automatically positioning the dental model with respect to the 3D medical scan record and automatically eliminating common (i.e., overlapping) portions from one of the data sets. Two-dimensional images can be mapped onto images generated from either of the first and second data sets to enhance accuracy and/or photo-realism.

A method, apparatus, and article of manufacture provide a system for electronically generating a color dental occlusion map within electronic model images. With the advances recently made computational systems, these computer based image systems may be used to permit end users to replace paper and physical models with electronic images. A mechanism to capture image representations of physical objects accurately and with sufficient resolution is provided in a form that is both inexpensive to operate while providing rapid turn-around for users. Second, a mechanism to visually display interaction between parts of an object is also provided. These features are expressly addressed for impressions of human teeth that are scanned to allow electronic images of the models of a patient's teeth to be represented and manipulated.

摘要:
A method for simulating tooth movement utilizes electronic modeling to represent the teeth. Instant centers of rotation are determined and projected paths of movement are plotted. The electronic model provides improved precision and provides a method for simulating movement in three dimensions. The movement from growth and/or correction is shown with the electronic model. The simulation provides for improved correction.

A method, apparatus, and article of manufacture provide a distributed computing system delivering and manipulating electronic model images to end users. One aspect of the present invention includes a method for providing electronic delivery of electronic model images. The method generates one or more electronic model images, a portion of the electronic model images being generated from scanned electronic data of a physical object, stores the electronic model images within computer readable memory of a server-based computing system, delivers the electronic model images to a remote client computer over a distributed communications network, manipulates the electronic model images upon the remote client computer, and performs analysis and a course of action using the manipulated electronic model images. The electronic model images comprise in part a polygonal mesh representation of the physical object.
