Embodiments of the invention can accommodate multiple variations and goals of impressions, including but not limited to dental and orthodontic models. To adapt embodiments of the invention for multiple purposes, and to standardize the process, embodiments include a housing that allows for impressions to be suspended and/or sealed in the housing so that modelling material can pour up the impression, form a model base or some other type of design, and/or articulate the models if desired, without the need for or with reduced need for trimming and substantial reduction of time and use of modelling material (hereafter “MM”) like gypsum, stone, plaster, resin, etc. Embodiments allow models to be created and formed and articulated if desired. Professionals may pour up impressions, form base models, and, optionally, articulate models, allowing less waste, material, and use of time than traditional and current methods.

A head frame apparatus is secured to a human head during maxillofacial surgery and includes devices to easily position and secure an endotracheal (breathing) tube and an anesthesia delivery circuit for the patient that reduces the likelihood that the flow of oxygen through the tube is restricted thereby reducing the risk of severe injury or death. The head frame apparatus also includes a removable reference indicator, which may be easily attached and removed while identifying a reference point of the patient's face. Also the reference indicator includes a universal joint and pointer with an attached ruler. A transport apparatus positions multiple preset reference indicators and allows for preoperative transportation and removal, while protecting the preset reference indicators from inadvertent adjustment. A bendable reference indicator used in an articulator for preoperative modeling allows for easily identifying reference points in a cast model. An orbiting segment apparatus positions a portion of a cast of a jaw in relation to a condyle ball of the articulator.

A denture including a denture base where artificial teeth are fixed, the denture base includes a reference denture base member to which the artificial teeth are fixed and an adjusting member formed of a cured body of a curable denture base material, the adjusting member being joined to the reference denture base member, the adjusting member includes an anterior adjusting member that is joined to a mucosal surface of a base anterior region to form an anterior region together with the base anterior region, and a posterior adjusting member that is joined to a mucosal surface of a base posterior region to form a posterior region together with the base posterior region, and at least parts of base edge side distal end regions in the anterior region and the posterior region are formed of the anterior adjusting member and the posterior adjusting member, respectively.

The present invention relates to a digital three-dimensional tooth model system. The digital three-dimensional tooth model system includes: an articulator mounted in a scan region of a tooth model scanner that creates virtual 3D tooth model data by scanning a tooth model and having a tooth model to be scanned installed thereon; an output unit connected to the articulator and matching and outputting position data of a tooth model scanned by the tooth model scanner and data storing anatomically ideal positions on an image; a reference mark composed of lines that can be vertically and horizontally analyzed; a tooth model unit composed of an upper jawbone tooth model and a lower jawbone tooth model designed by a digital tooth design program, and having modules each composed of the reference mark and the upper jawbone tooth model and the lower jawbone tooth model, respectively; and a tooth analyzer disposed between the upper jawbone tooth model and the lower jawbone tooth model. Accordingly, it is possible to increase accuracy by accurately positioning a tooth model in a peculiar scan region, using a tooth model scanner required to fabricate a digital three-dimensional tooth model at a dental clinic or a dental laboratory, and to enable smooth mastication and good pronunciation by enabling tooth models to be quickly and accurately engaged at ideal positions through modularization of a digital three-dimensional model and a reference line that enables positioning at anatomically ideal positions.

A device for making, duplicating and fixing dental models in articulator, using dental replicas (19) of plaster or other material with bases (20) for the manufacture of dental models (18).
