|20130171580||3D DIGITAL ENDODONTICS - A method and system are described for 3D digital endodontics characterized in that 3D imaging equipment such as a CT or MRI scanner, ultrasound or the like are used to digitize the infected tooth or teeth, a 3D representation of the root canal system is extracted from the image data and visualized on a computer screen, a surgical template is designed to guide the endodontic instruments to localize the root canal(s) intra-operatively and said guide is manufactured by means of a computer driven system (e.g. milling, rapid prototyping, etc.).||07-04-2013|
|20130089837||CUSTOM HEALING CAP FOR DENTAL IMPLANTOLOGY AND METHOD FOR DESIGN AND MANUFACTURING THEREOF - A computer based method is used to design a healing cap of an implant. The method is based on a 3D computer plan of the implant comprising digital representations of positions of implants in the mouth of the patient. The method comprises loading the 3D implant plan into a computer and combining the 3D implant plan with information about a prosthetic setup. The method determines a marginal edge of a healing cap of an implant based on a 3D representation of the existing patient anatomy, the 3D implant plan and the prosthetic set-up. The healing cap is then manufactured to the custom design.||04-11-2013|
|20120317080||METHOD AND SYSTEM FOR ARCHIVING SUBJECT-SPECIFIC, THREE-DIMENSIONAL INFORMATION ABOUT THE GEOMETRY OF PART OF THE BODY - A method and system for archiving 3D geometry information for a plurality of subjects, and on a particular part of the body (which may also be the whole body) is described. The method and system allow an organizing and an analyzing step, resulting in scalable characteristic components for the particular part of the body, and an approximation of the geometry of that particular part of the body for a specific subject by a combination of a sub-set of those characteristic components with corresponding scale factors, which are then stored. The method comprises the steps of: *organizing for each of said plurality of subjects the 3D geometry information according to a pre-determined standard, thus obtaining organized 3D geometry information; analyzing the organized 3D geometry information of said plurality of subjects, resulting in averaged 3D geometry information of said particular part of the body; and—scalable characteristic components of said particular part of the body; such that for each of said plurality of subjects said organized 3D geometry information can be approximated by a combination of said scalable characteristic components relative to said averaged 3D geometry information; comparing, for at least one out of said plurality of subjects, said organized 3D geometry information with said averaged 3D geometry information and determining a subset of said scalable characteristic components and corresponding scale factors, for approximating to a given accuracy said organized 3D geometry information relative to said averaged 3D geometry information by a combination of said scalable characteristic components out of said subset, each characteristic component scaled with its corresponding scale factor; storing, for at least one specific subject out of said plurality of subjects, said approximated organized 3D geometry information by storing—said averaged 3D geometry information;—said subset of said scalable characteristic components and said corresponding scale factors for said specific subject.||12-13-2012|
|20120010740||METHOD FOR PLACING AND MANUFACTURING A DENTAL SUPERSTRUCTURE, METHOD FOR PLACING IMPLANTS AND ACCESSORIES USED THEREBY - Method for placing and manufacturing a dental superstructure, method for placing implants, and accessories used in these methods.||01-12-2012|
|20110191081||METHOD TO DETERMINE THE IMPACT OF A PROPOSED DENTAL MODIFICATION ON THE TEMPOROMANDIBULAR JOINT - Use of computer technology for image-assisted risk assessment/evaluation of proposed dental treatments is described, in particular a method and apparatus for determining the impact of a proposed dental modification on the temporomandibular joint(s), e.g. to obtain information relating to that impact. Use of a virtual articulator is described to determine the impact of a proposed dental modification on the temporomandibular joint(s). This dental modification includes, but is not limited to, the replacement of one or more teeth by artificial teeth, the replacement of one or more parts of a tooth by a prosthetic reconstruction such as a dental crown or veneer, the rearrangement of one or more existing teeth (orthodontic treatment), the distraction of one or both jaws in order to reposition the teeth (orthognatic treatment) and/or modifications of the occlusal surfaces of the teeth.||08-04-2011|
|20100280798||TOOTH MOVEMENT SYSTEM AND METHOD - A patient's dentition is analysed to determine an orthodontic treatment plan by simulating an intervention in advance. 3D imaging techniques and computer technology are used to simulate and predict tooth movement as a function of the chosen treatment, i.e. a specific orthodontic appliance. In this way treatment options can be compared and the most optimal (shortest treatment time, lowest forces . . . ) treatment for each individual patient can be selected. Sub-steps of the tooth movement are not predefined but computed based on a simulation of orthodontic elements and wire as they would be used in the orthodontic treatment of the patient. This means that the sub-steps are calculated based on the relationship between the applied loads and the tooth movement; only one of both parameters can be chosen freely. Thus, either the tooth load is specified and applied in order to calculate the resulting tooth movement or vice versa the tooth movement is specified and applied in order to calculate the tooth load that should be applied. Moreover, the current invention allows predicting the time at which brackets and/or archwire should be changed, and comparing different treatment options with respect to tooth loading and duration.||11-04-2010|

|20090187393||METHOD FOR CREATING A PERSONALIZED DIGITAL PLANNING FILE FOR SIMULATION OF DENTAL IMPLANT PLACEMENT - The present invention provides a method for creating a personalized digital planning file for simulation of dental implant placement. After planning, the digital representation in a plaster model may be used to design and produce dedicated surgical templates to assist the surgeon in transferring the implant plan to a patient during medical intervention.||07-23-2009|
