Patent number: 10891403Abstract: Herein are provided methods, systems, computer-readable media, techniques and processes for occlusion estimation in dental prosthesis design. These include determining a first contact point between antagonist teeth, then simulating motion in order to determine additional contact points. Various of the determined contact points may not be used in the simulated motion, based on the simulated physics. When one or more predetermined stopping criteria have been met, then the contact points may be used to define the relative occlusal positions of antagonists. In some embodiments, sets of teeth in a bridge or crown, e.g., may be simulated as moving separately and a new state for each set of teeth may be determined.Type: GrantFiled: November 25, 2015Date of Patent: January 12, 2021Assignee: Biocad Medical, Inc.Inventors: Myriam Manai, David Giasson, Bin Hang

Patent number: 9934360Abstract: Presented herein are methods, systems, devices, and computer-readable media for dental data planning. In various embodiments, an operator of the system can design a dental data plan, have it checked, and see various aspects of the plan on the display. The plan may be designed in the abstract and that abstract plan can be checked for compliance with material and product constraints. Also from that abstract plan, a list of necessary scanning tasks may be produced and displayed. In some embodiments, plans for multiple patients can be designed and the scanning for those patients may commence before all of the patients are completed.Type: GrantFiled: February 10, 2010Date of Patent: April 3, 2018Assignee: Biocad Medical, inc.Inventors: Jean-Philippe Lajoie, David Giasson

Patent number: 9615902Abstract: The present disclosure relates to a method and device for producing a dental component. The method includes: a) providing a piece of material attached to or held by a first holder; b) shaping the piece of material to form the dental component and at least one support pin maintaining the dental component attached to the first holder or the initial piece of material; c) engaging a second holder to the dental component while the dental component still is attached to the first holder or the initial piece of material via the at least one support pin; and d) removing the at least one support pin from the dental component while the dental component is engaged by the second holder.Type: GrantFiled: November 18, 2011Date of Patent: April 11, 2017Assignee: BIOCAD MEDICAL INC.Inventors: Florent Miguel, Gilles Arnaud

Patent number: 9179988Abstract: Presented herein are methods, systems, devices, and computer-readable media for dental prosthesis connector design. Embodiments include providing a computer-based interface for manipulating a connector that connects a first dental restoration component and a second dental restoration component in a dental prosthesis; providing, via a cross-sectional representation of the connector, an acceptability design constraint for the connector, such as whether the connector meets production constraints and/or encompasses the intersection between neighboring teeth; modifying the connector based on operator input; determining whether the modified connector is acceptable with respect to the acceptability design constraint; and providing an acceptability indication for the modified connector, wherein said the acceptability indication is determined based at least in part on whether the modified connector is acceptable with respect to the acceptability design constraint.Type: GrantFiled: May 25, 2010Date of Patent: November 10, 2015Assignee: Biocad Medical, Inc.Inventors: Ion Dumitrescu, David Giasson

Patent number: 9089387Abstract: Herein are provided methods, systems, computer-readable media, techniques and processes for surface manipulation in dental prosthesis design. These include providing an interface for modifying the surface of a model of a dental prosthesis. This interface may be provided to an operator, dentist, dental practitioner, or any other appropriate person via a computer and a computer display. The operator provides areas in which the operator would like to add a layer or other limited manipulation to the surface of the model. This may include an addition to the surface or a subtraction from the surface. As the operator is defining additional areas to manipulate on the surface (e.g., add or subtract a layer), invariably some of them will overlap. Unlike previous methods, this overlap will not cause the amount added to the surface to increase beyond the predefined limit for the layer. This allows operators to define cleanly added layers or cleanly subtracted layers from dental prostheses.Type: GrantFiled: July 23, 2010Date of Patent: July 28, 2015Assignee: BIOCAD MEDICAL, INC.Inventor: Jean-Philippe Lajoie-Dorval

Patent number: 8949730Abstract: Presented herein are techniques methods, systems, devices, and computer-readable storage media for library selection in dental prosthesis design. Embodiments include presenting two or more dental morphology libraries for use in a dental plan and receiving a selection of one or more tooth morphologies from one of the presented dental morphology libraries. The selected tooth morphologies can then be placed in the dental plan at particular tooth positions. An operator can also replace all tooth morphologies in a dental plan with those of a particular library or “mix and match” tooth morphologies from multiple libraries in a dental plan.Type: GrantFiled: July 14, 2010Date of Patent: February 3, 2015Assignee: Biocad Medical, Inc.Inventors: David Giasson, Jean-Philippe Lajoie-Dorval

Patent number: 8712733Abstract: Herein are provided methods, systems, computer-readable media, techniques and processes for adjusting dental prostheses based on soft tissue. These include allowing an operator to define the surface of a dental prosthesis, such as an abutment, that is proximal to the patient's gum relative to a 3D scan of the patient's gums. The operator can define the offset of that surface as well as the limits of that surface.Type: GrantFiled: September 17, 2010Date of Patent: April 29, 2014Assignee: Biocad Medical, Inc.Inventors: Jean-Sebastien Auclair Beaudry, David Giasson

Patent number: 8594820Abstract: Methods systems, computer-readable media, techniques and processes for crown or prosthesis manipulation in dental prosthesis design include presenting a 3D model of a multi-tooth prosthesis relative to an area to be reconstructed. An operator may manipulate one or more prosthetic teeth in that 3D model in order to alter the overall shape of the prosthesis. The techniques may also include the determination of occlusion with respect to antagonist teeth—of the entire 3D model of the prosthesis and/or of individual 3D models of prosthetic teeth in the model. The position or shape of the 3D model of the prosthesis may be modified based on the occlusion.Type: GrantFiled: September 17, 2010Date of Patent: November 26, 2013Assignees: Nobel Biocare Services AG, Biocad Medical, Inc.Inventors: Myriam Manai, Adam Roberts, David Giasson, Bin Hang

Patent number: 8457772Abstract: Presented herein are methods and devices for designing dental components, such as physical models of a patient's anatomy, crowns and bridges. An operator of a prosthetic designing system can receive information, such as from a scanner, which provides information on the topology of the patient's dentition. The operator can use this information to design a custom prosthetic to fit the patient. Part of the designing process involves using a finish line defined for a preparation as a segmentation line for a physical die corresponding to the preparation, and using a path of draw line as an insertion axis line for a dental prosthetic.Type: GrantFiled: February 10, 2010Date of Patent: June 4, 2013Assignee: Biocad Medical, Inc.Inventors: David Giasson, Philippe-Armand Laberge, Marc Bedard, Urban Nilsson, Per-Olof Karlsson, Anna Persson
