A method may include receiving and digitally storing a preoperative data set including scan coordinates of at least one of a tomography and a topography of an oral structure of a patient, a dental impression of the oral structure, a dental cast of the oral structure, a prosthesis of the patient, and/or a prosthesis as applied to the oral structure. The method may also include digitally designing a digital preoperative dental model based on the preoperative data set and saving coordinates of the digital preoperative dental model in a CAD/CAM compatible file format. The method may further include digitally designing a dental appliance set based on the digital preoperative dental model, storing coordinates of the dental appliance set design, which are oriented to the digital preoperative dental model, in a CAM compatible file format, and manufacturing at least a part of the dental appliance set using a CAM method.

A method for auto-distribution of dental fixtures includes importing, via a processor, data corresponding to a computer-guided dental surgery to be performed, and analyzing, via the processor, the imported data to identify an optimal placement site for one or more implants of a dental fixture, the optimal placement site based on anatomical guideline parameters and biomechanical guideline parameters, the biomechanical guideline parameters including determination of a prosthesis-implant arch area ratio

Pre-surgical planning for cranial and facial reconstruction includes preparing a computer generated jaw or skull model for determining a locational position for a dental implant, a surgical bone implant to repair missing bone in the cranium, install ear prostheses, and/or install nose prostheses. The computer generated jaw or skull model is made from medical imagery and computer aided design. A surgical guide is prepared with oversize holes in registration with analogs for the dental or surgical bone implants to be inserted in the jaw or cranial skull model. The surgical guide is fitted atop each analog, and bonded to the jaw or skull model at a predetermined angle of the analog in the jaw or skull. The surgical guide is removed and attached to the jaw or skull of a patient for accurate drilling for insertion of the implants into the jaw or skull of the patient.

The present invention relates to a system which comprises a dental implant (10) and a replacement ring (28). The dental implant (10) has an insertion portion for anchoring in a jaw bone. The replacement ring (28) serves for replacing a subtractively removable annular material region in a coronal region of the insertion portion, the shape of the replacement ring (28) being inscribable into the shape of the dental implant (10) in the coronal region at least to some extent such that an inner lateral surface (32) of the replacement ring (28) lies within the shape of the dental implant (10).

A method of producing a dental splint comprising the steps of: obtaining a set of 3D surface data, the 3D surface data representing a surface of a patient's oral situation, and generating a support structure model in dependence on the 3D surface data, and producing the dental splint in dependence on the support structure model, wherein a 3D distance map image of the 3D surface data is used to generate the support structure model.

Provided is a guide pin for dental implant surgery, providing guidance so that a practitioner easily determines a location and angle of an alveolar bone of a patient when forming an implant hole in the alveolar bone to place an implant in the alveolar bone. By using the guide pin for dental implant surgery according to the inventive concept, a practitioner may perform the surgery by determining an accurate location and shape of the alveolar bone of the patient when drilling an implant hole in the alveolar bone, and thus, the success rate of the implant surgery may be increased.

The invention relates to manufacturing a surgical guide to be placed in a patient's mouth. The patient's mouth is scanned to obtain surgical-region scan data at a region where an implant is to be located. The patient's mouth is also scanned in the opened position to acquire dental conditions opposite from the surgical region so as to obtain opposing-condition scan data. A virtual model is developed using the surgical-region scan data and the opposing-condition scan data. Using the virtual model, a surgical plan is developed that includes the location of the implant to be installed in the patient. A virtual surgical guide is also developed based on the surgical plan. The dimensions of instrumentation to be used with the surgical guide are checked to ensure they will fit within the mouth by use of the opposing-condition scan data. After checking, final surgical-guide manufacturing information is obtained for manufacturing the surgical guide.

A method for producing a drilling jig to drill a drill hole in a jaw of a patient to insert a tooth implant therein includes providing a prosthesis with an individualized part and a standardized plate part. The prosthesis is adapted to and placed on the at least one of the jaw and teeth of the patient. A three-dimensional digital jaw model is created. The tooth implant is designed and digitally constructed in the three-dimensional digital jaw model. A drilling model is formed with a drilling model drill channel using the three-dimensional digital jaw model showing the planned tooth implant. The drilling model is mounted on the prosthesis. A prosthesis drill channel is drilled into the prosthesis in alignment with the drilling model drill channel to form the drilling jig for drilling the drill hole in the jaw of the patient for the tooth implant.

A tracking and guidance arrangement for a surgical robot system and related method are provided. The arrangement includes a patient-interacting device including an instrument engaged a distal end of a guide arm and a fiducial marker coupled to maxillofacial anatomy of the patient. A detector is connected to an articulating arm and co-operable therewith to be positioned adjacent to the fiducial marker, with the detector being configured to interact with the fiducial marker. A controller device is configured to receive data from the detector relative to the interaction thereof with the fiducial marker, to determine a spatial relation between the fiducial marker and the detector based on the data, to determine a spatial relation of the instrument relative to the fiducial marker, and to direct the instrument to interact with the maxillofacial anatomy of the patient according to the determined spatial relations.

A dental implant surgical guide device and method for guiding a surgical bur to a center location adjacent to at least one tooth during placement of an implant are presented. The dental implant surgical guide device may include a triangular body portion that may be inserted in a gap between two teeth, and a channel portion formed through the center of the body portion to allow the surgical bur to pass through the channel portion without contacting the body portion. Accordingly, a drill hole, and thus the implant, may be placed at the optimal, center location between the two teeth adjacent to the gap, and a distance between the two teeth may be accurately determined.
