Provided is a reference denture alignment jig which guides reference dentures into an oral cavity or to an articulator in which upper and lower edentulous jaw models are fixed, and aligns the reference dentures in the oral cavity or in the articulator in which upper and lower edentulous jaw models are fixed, the jig having a reference denture holding portion for holding reference dentures.

The present invention to a method of denture manufacture that incorporates CAM-formed occlusal portions made of zirconia, resulting in a natural fit, feel, and wear essentially similar to the wear properties of natural teeth.

In a shell for adapting a retention element to an anchoring element, and a method of forming a further retention element on an anchoring element including a shell, the shell has an internal cavity, the dimensions of which are matched to the external dimensions of the retention element and which is connectable to the retention element in an integral or form-fitting manner, and has an outer surface which is formed as a further retention element.

Dental devices and systems and methods for making dental devices are described herein. In some embodiments, denture base material may be adapted to fit a model of a patient's mouth, and a pre-set arch of denture teeth may be adjusted the model. The pre-set arch may be impressed into the denture base material to create a channel. In some embodiments, the cure may be a partial cure and/or a releasing agent may be used such that the pre-set arch may be removed, if needed for further adjustments, after assessing the fit of the denture device. If the fit is correct, another cure may be performed to finish the denture device. If the fit is incorrect, a new bite registration and/or adjustments to the denture base material and/or pre-set arch of denture teeth may be made.

A method for forming and setting a denture has the following steps: using a stereoscopic scanner to capture a patient's maxillary, mandibular gum shapes to generate stereoscopic maxillary, mandibular gum data and an occlusion record of a patient's maxilla and mandible; using a computer tomography scanner to scan patient's maxilla, mandible shapes to generate tomographic maxilla, mandible data; using a 3D processing device to consolidate the stereoscopic maxillary, mandibular gum data, occlusion record of a patient's maxilla and mandible, tomographic maxilla, mandible data to generate 3D full-tooth data; planning detailed positions and sizes of a upper (lower) prosthesis adapted to set on the patient maxilla (mandible) side, a plurality of upper (lower) fixing elements for fixing the upper (lower) prosthesis through the 3D full-tooth data; and making the upper, lower prostheses, and using each upper (lower) fixing element to implant the upper (lower) prosthesis into the patient's maxilla (mandible).

To provide try-in dentures which make it possible to adjust a bite more easily with high accuracy, a denture base part 12; a dentition part 13; an adjustment part 15; and a base part 14 are included, the adjustment part and the base part being separable from each other, and the adjustment part includes all of occlusal surfaces 13b of the dentition part, and a face 15a parallel to an occlusal plane 10a, the adjustment part being formed so that a movement of the adjustment part parallel to the occlusal plane with respect to the base part can be performed, a rotation of the adjustment part in the face parallel to the occlusal plane can be performed, or both the movement and the rotation can be performed.

Computer implemented methods and user interfaces for facilitating the design of a so-called copy denture, whereby an existing denture is reproduced after making changes to the existing denture to improve fit, aesthetics or other parameters. A method may include the steps of obtaining a digital model of an existing denture, segmenting the digital model of the existing denture into an intermediate denture base model and at least one intermediate denture teeth model, and generating a digital data file of a final denture base model based on the intermediate denture base model and providing a digital data file of at least one final denture teeth model based on the at least one intermediate denture teeth model.

The invention relates to a method for producing a monolithic form body, in particular a dental restoration, comprising the steps of: providing of a blank, producing of the form body through pressing and/or machining of the blank, and softening of the form body exclusively in its surface region by irradiation with infrared radiation.

A dental material having at least one copolymer obtained by (I) copolymerizing one or more monomers M.sub.G having a polymerizable (meth)acrylate group, one or more OH group-containing (meth)acrylates M.sub.F, one or more strongly acidic adhesive monomers M.sub.H and optionally of one or more polymerizable carboxylic acid monomers M.sub.CS, (II) reacting the resulting copolymer A.sub.0 in a polymer-analogous reaction with a functionalized, radically polymerizable monomer M.sub.P, which reacts with the OH groups of the monomer M.sub.F in the polymer chain of A.sub.0 to form a copolymer A.sub.P having pendant polymerizable groups, and (III) neutralizing the copolymer A.sub.p with a base. The material is particularly suitable as a dental adhesive.

Various methods and systems are provided for multifunctional denture systems. In one example, among others, a multifunctional oral prosthetic system includes an oral prosthetic device that may be located in an oral cavity. The oral prosthetic device includes a plurality of sensors and an internal module in communication with the plurality of sensors. The internal module is configured to provide sensor data corresponding to at least one of the plurality of sensors to an external processing unit when located in an oral cavity.
