20230059202 · 2023-02-23 ·

Reciprocal positions of negative casts (2, 3) upper and lower dental arches, of a subject (S) recipient of a dental prosthesis (1), by means of an attitude detection device (40).

These positions are then transferred to a manual articulator (50) to be able to positionpositive models (20, 30) of the same upper and lower dental arches with a dentation model form for a dental prosthesis (1).

Using a column template (6), (50) adjustments are detected and brought back to an articulator robot (90), operated by actuators (94).

Chewing movements of the subject (S) are video-taped and digitized, so that a program generator (80) provdes a sequence of commands for driving the robot to move the models (20, 30) to replicate mandibular movements of the subject (S) so as to enable evaluation of correctness of the dentation model form, and possibly modify.

These methods and systems include both model-based services and CT (computed tomography) guided surgery services. Using these services, improved surgical guides for dental implants are constructed.

System and Method for Predicting a Crown and Implant Feature for Dental Implant Planning

A method for predicting at least one of a tooth crown or implant feature, said method comprising the steps of: receiving at least one of a volumetric or surface scan image, wherein the volumetric image is a three-dimensional voxel array of a maxillofacial anatomy of a patient and the surface scan image is a polygonal mesh of a maxillofacial anatomy of the patient; segmenting at least one of the volumetric image or surface scan image into a set of distinct anatomical structures by assigning each voxel an identifier by structure and assigning at least one of a vertices, face, or points on the mesh an identifier by structure for the volumetric image and surface scan image, respectively, wherein the distinct anatomical structures include at least one of a tooth, jaw, mandibular canal, maxillary sinus, fossae, and a missing tooth; and predicting at least one of a tooth crown or implant feature in place of the segmented missing tooth, wherein the predicted crown and/or implant feature is at least one of generated or selected from a library.

Methods of designing and manufacturing customized dental prosthesis for periodontal or osseointegration and related systems

Methods of manufacturing dental prosthesis/implants each to replace a non-functional natural tooth positioned in a jawbone of a specific pre-identified patient are provided. An example method includes the steps of receiving imaging data such as x-ray image data and surface scan data of a dental anatomy and/or a physical impression of the dental anatomy of a specific preidentified patient. The steps can also include forming a three-dimensional virtual model of at least portions of a non-functional natural tooth positioned in the jawbone of the specific pre-identified patient based on the imaging and surface scan data, virtually designing a dental implant based upon the virtual model, exporting the data describing the designed dental implant to a manufacturing machine, and custom manufacturing the dental implant for the specific patient.
