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.

Provided is a system and method for smart dental unit. The system provides smart dental unit restoring one or more teeth, including: a prosthetic base structured and arranged to engage with mouth tissue. The prosthetic base supports at least one tooth and at least one sensor system structured and arranged to detect at least one event. The sensor system further has a processor coupled to a wireless transceiver operable to communicate with at least one remote computing system. The smart dental unit also has a unique identifier. In response to a detected event the processor generates data communicated by the wireless transceiver to the remote computer. The unique identifier is also used by the remote computer to determine the location of the smart dental unit. An associated method for making a smart dental unit and a system for dental based patient care are also disclosed.

A computer-implemented method of generating a dental model based on an objective function output, including creating an objective function including at least one quality estimation function which trains at least one machine learning method that generates quality estimation output, and an objective function output is the output of the objective function providing a model as an input data to the objective function and generating model-related objective function output; and modifying the model based on the model-related objective function output to transform the model to a generated model, wherein the generated model is the dental model.

A method of placing a dental implant analog in a physical model for use in creating a dental prosthesis is provided. The physical model, which is usually based on an impression of the patient's mouth or a scan of the patient's mouth, is prepared. The model is scanned. A three-dimensional computer model of the physical model is created and is used to develop the location of the dental implant. A robot then modifies the physical model to create an opening for the implant analog. The robot then places the implant analog within the opening at the location dictated by the three-dimensional computer model.

A method of making a physical object by additive manufacturing. The method has the steps of providing a light hardenable primary material (11), building up the object (100) by successively hardening portions of the light hardenable primary material (11) by irradiating the portions with light, coating at least a part of the object (100) with a light permeable coating or oxygen protective material; and irradiating the coated object (100) with light and thereby post-hardening any light hardenable material (11).

The present invention relates to a method for fabricating a dental restoration, comprising the steps of rendering (S101) a first digital tooth model with a first material combination for generating a first actual data set representing the optical properties of the first digital tooth model; determining (S102) a first deviation between a target data set and the first actual data set; rendering (S103) a second digital tooth model based on a second combination of materials to generate a second actual data set representing the optical properties of the second digital tooth model; determining (S104) a second deviation between the target data set and the second actual data set; and fabricating (S105) the dental restoration based on the first digital tooth model when the first deviation is less than the second deviation and fabricating the dental restoration based on the second digital tooth model when the second deviation is less than the first deviation.

A method of additive manufacturing of three-dimensional objects by sequentially dispensing and solidifying layers. The layers may include (i) stacks of model layers arranged in configured patterns corresponding to shapes of one or more objects and being made of one or more modeling materials; (ii) an intermediate layer surrounding said shapes of one or more objects and comprising at least a support material, and (iii) a flexible overlay surrounding said first intermediate layer, the intermediate layer and flexible overlay forming a flexible sacrificial structure. The model stack or stacks can be removed from the flexible sacrificial structure by application of pressure to the flexible sacrificial structure, separating the model stack from the flexible structure along the intermediate layer.

A dental alignment guide system for dental implant placement has an anatomical guide, a tooth supported guide and a surgical guide. The system further can have an articulation piece, a prosthetic seat, an analog anatomical model and artificial teeth. The system has a plurality of implants, the implants being abutments, preferably multiunit abutments, a plurality of screws for attaching the anatomical guide to bone, pins to removably attach the various guides and the artificial teeth to the anatomical guide as assemblies during the method of practicing the invention.

Systems, methods, and/or computer-readable media described herein provide technical solutions to the highly technical problems of machine generation of dental restorations. In particular, these systems, methods and/or computer readable media may provide technical solutions to aid in the creation of dental restorations that more closely resemble a natural tooth (including its internal optical structure). These systems, methods and/or computer readable media may help in virtually rendering a tooth, including its internal optical structure, and apply these renderings (e.g., digital models) to the fabrication of the dental restoration.
