Techniques are described for automating the design and manufacture a dental restoration appliance for restoring the dental anatomy of a patient. For example, a system processes a digital three-dimensional (3D) model of a future (desired) dental anatomy of a patient, the future dental anatomy representing an intended shape of at least one tooth of the patient. The system includes a landmark identifier configured to automatically compute, based on the digital 3D model of the future dental anatomy of the patient, one or more landmarks of the future dental anatomy of the patient. The system also includes a custom feature generator configured to automatically generate, based on the one or more landmarks, one or more custom appliance features for a dental appliance for restoring the at least one tooth of the patient. The system further includes a memory device configured to store a digital model of the dental appliance.

A biomimetic composite material includes a bioactive cement material, an autologous dentin matrix, and an inorganic nano-reinforcement material. A dental implant includes a body including a biomimetic composite material, wherein the biomimetic composite material includes a bioactive cement material, an autologous dentin matrix, and an inorganic nano-reinforcement material.

A dental matrix includes an outwardly extending column, which is engaged by an instrument, allowing the dentist to move the instrument and maneuver the matrix into position on the operative tooth to create a cavity for the veneer. The cavity is filled with curable material, which is cured by light, such as ultraviolet light, and once curing is complete, the matrix is removed from the tooth, which now has the veneer formed thereon.

Various embodiments described herein generally relate to apparatuses and methods for performing bone implants such as, but not limited to, dental implants, knee and joint replacements, and various types of bone anchored prosthesis. For a better understanding of how the various apparatus and methods can be used for bone implants, an example will be given herein with respect to dental implants.

A process for the production of a dental shaped body, such as a dental blank or a dental restoration, in which a suspension of a zirconium oxide starting material is gelled by means of a gelling agent, and the use of a suspension of a zirconium oxide starting material as dental material, the suspension containing a gelling agent.

Polymerizable resin compositions and methods are provided for preparing shaped parts such as dental prosthetic devices and non-prosthetic dental appliances. The compositions are amenable to 3D printing and the polymerized compositions are capable of exhibiting improved strength properties, increased toughness, and good flexibility.

A method for scaling the porcelain material of a restoration and the associated machining process is invented, which comprises: establishing a data model of the restoration (S100); dividing the bonding surface or interface between veneer porcelain to be prepared and a restoration substrate into a finite number of element surfaces (S200); establishing the direction coordinate axis on every element surface as its reference axis for setting up a size and a thickness value of veneer porcelain of each element surface (S300); determining and specifying the size and thickness of the veneer porcelain of every element surface according to the preset size and thickness value, and completing the bonding surface by covering it with the veneer porcelain composed of all the element surfaces as scaled with those sizes and thickness values as referred to (S400); generating the outer contour of the veneer porcelain of a clinic restoration (S500).

Methods for taking a scan of a patient's oral cavity for use in fabricating a dental prosthesis. Such methods may include providing a healing cap configured to be received within a subgingival void of a given tooth position, taking a first scan of the healing cap, wherein the first scan is taken outside of a patient's oral cavity, seating the healing cap, taking a second scan, which is an intraoral scan of the healing cap and surrounding surfaces once the healing cap is seated, taken inside the patient's oral cavity; and integrating the first scan of the healing cap with the intraoral second scan of the healing cap and the surrounding surfaces into an overall oral cavity scan. A third scan, (e.g., 3D cone beam scan), can also be taken, which is overlaid or otherwise integrated with the first and second scans, for use in fabrication of a dental prosthesis.

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

The present invention relates to a method of manufacturing a dental component, in particular a dental prosthesis or a partial dental prosthesis, by means of a dental furnace, comprising the following steps: (i) preparing a virtual model of the dental component; (ii) automatically selecting one, two or more programs and/or automatically preparing one, two or more programs and/or preparing one, two or more suggestions for a program for operating the dental furnace on the basis of the virtual model of the dental component; (iii) producing a model of the dental component; (iv) embedding the model in an investment material; (v) removing the model from the investment material, in particular by heating or burning out, to obtain a negative mold of the model; (vi) inserting a raw material required for manufacturing the dental component into the negative mold; and (vii) producing the dental component in the negative mold in the dental furnace on the basis of the selected, prepared, or suggested program.
