A wax model of a required coping is produced using CNC machining techniques based on a virtual model of the coping created from digital data obtained from the intraoral cavity. The dental coping is then fabricated from the wax model.

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 invention relates to a coloured curable composition for use in an additive manufacturing process, the composition comprising a curable resin composition comprising radiation curable components, a photo initiator, a dye composition comprising a dye D1 and a dye D2, dye D1 having a light absorption maximum within a wave length range from 400 to 530 nm, dye D2 showing a light absorption maximum within a wave length range from 540 to 650 nm. The invention also relates to a 3-dim composite article obtained by processing the curable composition in an additive manufacturing process.

A custom tool for forming a dental restoration in a mouth of a patient includes a mold body providing for a customized fit with at least one tooth of the patient. The mold body includes a facial portion forming a facial surface corresponding with a facial surface of the tooth, and a separate lingual portion forming a lingual surface corresponding with a lingual surface of the tooth. The mold body is configured to combine with the tooth of the patient to form a mold cavity encompassing missing tooth structure of the tooth.

A manufacturing method for a prosthetic apparatus for dental purpose according to one aspect of the present invention includes: acquiring scan data of a model that is a reproduction of at least a part of an inside of an oral cavity of a patient; creating shape data of a shaped body for dental purpose on a basis of the scan data; producing a shaped body on a basis of the shape data; covering at least a part of the shaped body and at least a part of a model with film, the shaped body attached to the model; releasing air in a part covered with the film to deform the film and bring the shaped body into close contact with the model; and curing the shaped body in a state where the shaped body is in close contact with the model.

Provided herein are systems and methods for scoring a post-treatment tooth position of a patient's teeth. A patient's dentition may be scanned and/or segmented. Raw dental features, principal component analysis (PCA) features, and/or other features may be extracted and compared to those of other teeth, such as those obtained through automated machine learning systems. A classifier can identify and/or output the post-treatment tooth position of the patient's teeth.

Modelling material which includes (a) at least one radically polymerizable monomer, (b) at least one initiator for the radical polymerization and (c) at least one inert component. The inert component (c) is soluble in the polymer formed by polymerization of the monomer (a), wherein the solubility of component (c) decreases as the temperature increases, with the result that a phase separation takes place above a particular temperature. The material is suitable in particular for the production of models of dental restorations for investment casting processes.
