Methods of making the dental retainer devices are also provided. The methods can included additive manufacturing. Methods are also provided for customization of a dental retainer device based on the patient specific anatomy. The methods for customization can include providing a dentist with different options for anterior teeth coverage, posterior teeth coverage, and palatal configurations for the dental retainer devices.
Method for manufacturing surgical guide and crown, abutment in mouth for dental implant
Provided is a method for manufacturing a surgical guide, and a crown and an abutment in a mouth for a dental implant, including an operation of obtaining a primarily scanned image through scanning of inner and outer surfaces of a denture which has a first image matching groove matched with a patient's tooth implanting portion and in which a plurality of reference markers are attached to an outside, obtaining a secondarily scanned image through oral scanning of upper and lower jaws while the denture is installed, preliminarily matching the secondarily scanned image with the primarily scanned image, obtaining an integrated scanned image considering a vertical dimension by reversing the first image matching groove so that an image of the first image matching groove is dimensionalized from the primarily scanned image, and obtaining a CT image through CT scanning of the upper and lower jaws.
Image guided navigation system
An image guidance system for tracking a surgical instrument within the oral cavity. The image guidance system includes a plurality of cameras adapted to be located within the oral cavity to provide intraoral images of optically visible patterns within oral cavity. A processing system receives and processes the intraoral images to recognize patterns and triangulate the locations and orientations of each camera. The processing system uses a reference dataset which defines a reference coordinate system based on alignment to a portion of the oral anatomy. The processing system determines the location and orientation of the tracked instrument based on the reference dataset. In an embodiment, the system includes an oral fixture that is removably attachable to teeth in a patient and is configured to hold one of the cameras.
Filling undercut areas of teeth relative to axes of appliance placement
The present disclosure provides computing device implemented methods, computing device readable medium, and molds for filling undercut areas of teeth relative to an axis of placement. Filling undercut areas of teeth relative to an axis of placement can include calculating an undercut area of a tooth relative to an axis of placement of part of a dental appliance over a number of teeth and a height of contour that is defined based on the axis of placement. Filling undercut areas of teeth relative to an axis of placement can also include filling in a part of the undercut area of the tooth with a virtual filler wherein the undercut is filled to within a threshold distance from the tooth that is defined relative to the axis of placement and the height of contour.
Prosthodontic and orthodontic apparatus and methods
System and method for developing a treatment plan for achieving a treatment goal including creating a virtual model of a dental patient's dentition; transforming the virtual model of the dentition using virtual prosthodontics to facilitate achievement of the treatment goal; transforming the virtual model of the dentition using virtual orthodontics to facilitate achievement of the treatment goal; iterating on the transforming steps until substantially achieving the treatment goal; and generating an orthodontic treatment plan and a prosthodontic treatment plan based upon the substantially achieved treatment goal.
Systems and methods for determining a tooth trajectory
A method and a system for determining a tooth trajectory for a given tooth of a subject are provided. The method comprises: generating, by executing an optimization algorithm, based on a 3D model of the given tooth, a plurality of segments defining a tooth trajectory of the given tooth from its initial position to its target position. The executing comprises: determining, based on the stress values range, an initial force to be applied to the given tooth, the initial force causing a maximum displacement of the 3D model of the given tooth from the start position associated with the given segment towards the target position associated with the given tooth, thereby identifying an end position associated with the given segment. The method further comprises determining a respective force applied to at least one other 3D model by the maximum displacement of the 3D model of the given tooth.
ASCERTAINING THE SPATIAL POSITIONS AND ORIENTATIONS OF IMPLANTS ANCHORED IN A JAW OF A PATIENT
A method is proposed for ascertaining the spatial positions and orientations of at least two implants (120) anchored in a jaw of a patient, said method having the following steps: 1. An adhesive bond aid (100) is produced that bridges the implants and has negative molds (140) of adhesive caps (110), wherein the negative molds fit on the adhesive caps if these are affixed to the implants, and wherein the negative molds allow a clearance relative to the adhesive caps. 2. The adhesive caps are affixed to the at least two implants in the jaw of the patient. 3. The adhesive bond aid is positioned over the adhesive caps. 4. The clearance between the adhesive caps and the negative molds is filled with adhesive. 5. The adhesive is cured. 6. The adhesive caps are released from the implants. 7. The obtained adhesion key is removed from the patient. Using this adhesion key, in the production of restorations that rest upon multiple implants, it can be ensured that the implant arrangement is correctly transferred into the mouth of the patient.
TOOTH-BORNE GUIDE PLATE, MUCOSA-BORNE GUIDE PLATE, BONE-BORNE GUIDE PLATE, AND PREPARATION AND APPLICATION METHODS THEREFOR
The present invention relates to a tooth-borne guide plate, a mucosa-borne guide plate, a bone-borne guide plate, and preparation and application methods therefor. The method for preparing a tooth-borne guide plate comprises: a) bonding a radiopaque material to teeth, bonding the radiopaque material to the gingival mucosa or/and bonding the radiopaque material to other anatomical features; b) performing CBCT photography, and acquiring CBCT data with radiopaque material information; c) acquiring oral cavity surface STL data with radiopaque material information; d) matching the CBCT data with the STL data; e) determining the positions of an implant and a retention pin; f) generating a base guide plate; g) generating an in-place guide plate; h) generating an implant guide plate; and i) generating a repair guide plate. By means of the tooth-borne guide plate, the mucosa-borne guide plate, the bone-borne guide plate, and the preparation and application methods therefor provided in the present invention, the precision and success rate of data matching can be improved, thereby improving the patient's comfort, reducing the number of subsequent visits, and reducing clinical medical costs.
Therapeutic Tooth Bud Ablation
Ablation probe tips (108, 148, 320, 360) and physical and virtual stents (110) for use in tooth bud ablation procedures that result in tooth agenesis as well as tooth bud ablation methods are described herein.
System and Method for Making Dental/Medical Devices Using Patient Mouth as Articulator
Creating a replacement tooth or set of teeth by using the patient's mouth as an intra-oral articulator. Also, a medical appliance can be created by using the patient's mouth as an intra-oral articulator. A mechanism is fitted within the patient's mouth which can hold one or more replaceable teeth. The dentist adjusts the size, color, location and placement of the teeth within the patient's mouth until a best fit is achieved. Then, the device, with the artificial and temporary teeth secured thereto, is further processed into a final replacement tooth (teeth). Also, the present system can be used for any dental or medical appliance in or about the mouth, i.e., using the mouth of the patient as the intra-oral articulator will result in superior results.
