The present disclosure reveals a provisional dental restoration for use at the time of dental implant surgery and while the permanent long-term restoration is being fabricated and implants are healing, which aids in the surgical process and selection of potential abutments at the time of surgery. Also revealed is a new digitally designed impression prosthesis from which the doctor is able of capturing the occlusal record, an impression of the soft tissue and critical aspects of the tooth position and orientation in a single procedure.

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 tray appliance system is usable for obtaining a bite registration and includes a maxillary tray appliance and optionally a mandibular tray appliance. The maxillary tray appliance includes a first contacting portion that extends downwardly from a first base portion. The first contacting portion includes a first contacting surface, a first ridge line, and a first ridge line midpoint. The optional mandibular tray appliance includes a second contacting portion that includes a second contacting surface, a second ridge line, and a second ridge line midpoint. The first contacting portion and second contacting portion contact each other when a patient bites down with the maxillary tray appliance and the mandibular tray appliance situated in the patient's mouth.

The invention relates to a method for producing a dental prosthesis having the following chronological method steps:

a) a first, provisional dental prosthesis comprising at least one first prosthetic base (1) and several provisional prosthetic teeth (4) is produced, whereby data that indicate at least the 3-dimensional form of the occlusal surfaces (6) of the provisional prosthetic teeth (4) of the provisional dental prosthesis are stored as data record A or have already been stored as data record A

b) after subtractive occlusal processing of at least one of the provisional prosthetic teeth (4), at least the 3-dimensional occlusal surfaces (6) of the processed provisional prosthetic teeth (4) of the first dental prosthesis are determined, or the 3-dimensional surface of the first dental prosthesis is determined as a whole

c) data that indicate at least the 3-dimensional form of the occlusal surfaces (6) of the processed provisional prosthetic teeth (4) are stored as data record B

d) via a computer comparison of data record B with data record A, the differences in the forms of the provisional prosthetic teeth (4) before and after the subtractive occlusal processing are calculated and, from this, at least desired lengths for final prosthetic teeth (20) are calculated, and

e) final prosthetic teeth (20) are produced at least with the calculated desired length using a CAM method from virtual models of the final prosthetic teeth (20), whereby the desired length of the final prosthetic teeth (20) is set by a basal shortening of the virtual models of the final prosthetic teeth (20), and the final prosthetic teeth (20) produced in such a manner are firmly connected to the at least one first prosthetic base (1) or at least one second prosthetic base.

The invention further relates to a dental prosthesis produced with such a method.

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 zirconia teeth or zirconia tooth segment members, resulting in a natural fit, feel, and wear essentially equivalent to the wear properties of natural teeth, with wear and durability properties superior to dentures known in the art.
