The invention provides a dentition movement track indicator and a tracing method. The device includes an intra-oral fixation assembly and an extra-oral movement indicating assembly, wherein the intra-oral fixation assembly includes a lower denture base, a left side retention steel wire, a right side retention steel wire and a positioning steel wire. The lower denture base is arranged on the lingual side of the lower dentition and respectively extends from a lower incisor to the far center of the last tooth on the left side and the right side and clings to the lingual mucous membrane. The left side retention steel wire and the right side retention steel wire are distributed in a left-right symmetry mode. The extra-oral movement indicating assembly includes a connecting rod, an arc rod, an indicating plate and a plurality of rectangular parallelepiped thin rods. According to the dentition movement track indicator, an intra-oral fixation assembly.

A method of making a maxillary tray appliance comprises obtaining a first virtual model of an edentulous maxillary gum of a patient, and obtaining a virtual component, where the virtual component comprises a virtual contacting surface. The method further comprises receiving the first virtual model, aligning the first virtual model or the virtual component in 3D space, generating a virtual tray appliance, and fabricating a maxillary tray appliance using the virtual tray appliance.

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.

Herein are provided methods, systems, computer-readable media, techniques and processes for occlusion estimation in dental prosthesis design. These include determining a first contact point between antagonist teeth, then simulating motion in order to determine additional contact points. Various of the determined contact points may not be used in the simulated motion, based on the simulated physics. When one or more predetermined stopping criteria have been met, then the contact points may be used to define the relative occlusal positions of antagonists. In some embodiments, sets of teeth in a bridge or crown, e.g., may be simulated as moving separately and a new state for each set of teeth may be determined.

The invention relates to a denture, made of teeth, in particular prefabricated teeth, and of a denture base made of a gingival material, comprising cavities for teeth in which cavities for the teeth are mounted, in particular attached by bonding, characterized in that the denture base (12) is produced by a CAD/CAM process forming the cavities (20) for the teeth (14), and in that cervical areas (40a) of the teeth (14) extending through the basal surface (16, 18) of the denture base (12) are removed, in particular abraded or milled.

A method for producing partial dental prosthesis having at least one surface for forming a chewing surface of a posterior tooth is provided. The method includes (i) providing a composite material with at least one organic binding agent and solid particles that consist of glass as filler; and (ii) applying a laser to at least some regions of a surface of the chewing surface such that the at least one organic binding agent is burnt off in laser-treated regions and the solid particles are melted and fused together to form a continuous enamel layer.

A dental tray appliance system including a maxillary tray appliance and optionally a mandibular tray appliance. The maxillary tray appliance includes a first base portion, a first premolar tooth form, optionally a first contacting portion, optionally a contralateral first premolar tooth form, and optionally a central incisor tooth form. Each premolar tooth form has no lingual cusp as part of improvements in occlusal registration components. The mandibular tray appliance includes a second base portion, optionally a second contacting portion; and optionally a second bite material accepting portion.
