Systems and methods for orthognathic surgical planning are described herein. An example computer-implemented method can include generating a composite three-dimensional (3D) model of a subject's skull, defining a global reference frame for the composite 3D model, performing a cephalometric analysis on the composite 3D model to quantify at least one geometric property of the subject's skull, performing a virtual osteotomy to separate the composite 3D model into a plurality of segments, performing a surgical simulation using the osteotomized segments, and designing a surgical splint or template for the subject.

An additively manufactured dental crown with a wall having a bottom edge and an occlusal portion joined with the wall opposite the bottom edge. The wall and occlusal portion form an interior surface and an opposing exterior surface. By using additive manufacturing and materials for such, the dental crown can have thin walls with a thickness of less than 300 microns at the thinnest portion of it and can include fine printed features such as identifiers, internal ribs, slots, porous meshes, and retention elements.

Methods and apparatuses, including systems, for forming and modifying treatment plans, including modifying treatment plan in real time. In particular are methods and apparatuses for modifying and orthodontic treatment plan in real time that may include the use of an enhanced user interface including a 3D user overlay.

A customizable implant made of plastic including a thermoplastic which is reinforced with long fibers arranged multidirectionally in a targeted manner and has a modulus of elasticity E of 10-70 GPa is provided. A system for producing a customizable implant including a device for collecting patient data regarding the environment into which an implant is to be inserted, a computer program for creating a model for a customized implant based on the patient data collected, and a device for producing the customized implant based on the calculated model by means of 3D printing and/or laser sintering is also provided.

Provided is a method of forming a customized alveolar bone tissue. The method includes obtaining first data having image information corresponding to an original alveolar bone of an alveolar bone defect, obtaining second data having image information on a defective portion of the alveolar bone defect, calculating third data having image information on a barrier membrane covering the alveolar bone defect by using the first data and the second data, and forming a barrier membrane artificial tissue corresponding to the barrier membrane by using the third data.

The present disclosure provides methods, devices, systems, and computer-implemented methods for forming and placing attachments for use with dental appliances, and more particularly to the design, manufacture, and use of three-dimensionally printed attachment templates for use with orthodontic devices. Dental attachment templates include a cavity with one or more openings for injecting and bonding attachment material directly on a patient's tooth, which allow accurate placement of the attachments while providing the dental practitioner flexibility during the attachment forming process. Digital dental attachment template model techniques can be used to accurately place the cavity and opening.

The present disclosure provides a photopolymerizable composition comprising 50-90 wt % of at least one urethane component, 5-50 wt % of at least one reactive diluent, 0.1-5 wt % of a photoinitiator, and optionally an inhibitor, wherein said composition has a viscosity at a temperature of 40 degrees Celsius of 10 Pa.Math.s or less, as determined using a magnetic bearing rheometer using a 40 mm cone and plate measuring system at a shear rate of 0.1 l/s. The present disclosure also provides an article including the reaction product of the photopolymerizable composition, in which the article exhibits an elongation at break of 25% or greater. Further, the present disclosure provides a method of making an article including (i) providing a photopolymerizable composition and (ii) selectively curing the photopolymerizable composition to form an article. The method optionally also includes (iii) curing unpolymerized urethane component and/or reactive diluent remaining after step (ii). Further, methods are provided, including receiving, by a manufacturing device having one or more processors, a digital object comprising data specifying an article; and generating, with the manufacturing device by an additive manufacturing process, the article based on the digital object. A system is also provided, including a display that displays a 3D model of an article; and one or more processors that, in response to the 3D model selected by a user, cause a 3D printer to create a physical object of an article.

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.
