摘要： One embodiment of the apparatus and method is a computerized system (3000) comprising; a handpiece (106) integrating at least one sensor (110) and attaching a cutting tool (104); and at least one other sensor (110) adhered to an arch (112), the arch (112) having a tooth (108) to receive a crown. Another embodiment comprises the computerized system (3000) having a capacity to facilitate configuring of a prepared tooth to generate a digital file. Another embodiment comprises the computerized system (3000) having the capacity to produce an auditory, lighted, or vibration signal, alerting the dentist to increase or decrease the line-of-draw surface tapers (118) as needed to fit a crown. Another embodiment comprises the computerized system (3000) having the capacity to produce signals, alerting the dentist to move on to other surfaces of the prepared tooth as soon as the reduced surface (116) has been adequately reduced to fit a crown. Some of the digital workflow embodiments facilitate configuring of the prepared tooth that fits a premanufactured crown while other embodiments create the digital file that facilitates fabrication of a custom crown.

摘要： Proposed is a method of manufacturing a dental composite blank. The method of manufacturing the dental composite blank includes (a) pressurizing a laminate for a composite blank having multiple layers having different colors at a first pressure (P1), (b) pressurizing the laminate for a composite blank, pressurized at the first pressure, at a second pressure (P2), and (c) manufacturing a composite blank by curing the pressurized laminate for a composite blank, in which steps (a) and (b) are each independently performed once or multiple times, and the first pressure (P1) is less than or greater than the second pressure (P2), ultimately making it possible to manufacture a dental composite blank that is similar to a natural tooth and thus exhibits a superior aesthetic appearance and high interlayer bonding strength.

摘要： Disclosed is a machinable dental bulk block that is a glass ceramic block including an amorphous glass matrix and crystalline phases introduced into the matrix. A major crystalline phase is lithium disilicate and minor crystalline phases are lithium phosphate and at least one of spodumene and virgilite. The dental block is made of a functionally gradient material in which the major crystalline phase exhibits a gradient of particle sizes in a depth direction of the dental block and which has no interface at a point where the gradient of particle sizes of the major crystalline phase changes. The dental bulk block is useful for production of a dental prosthesis (artificial tooth) similar to a natural tooth. The dental bulk block can reduce time and the number of processing steps to manufacture a dental prosthesis and provides improved structural stability through good force distribution obtained by functionally graded mechanical properties.

摘要： 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.

摘要： The invention relates to a method of producing a dental prosthesis from a one-piece or multi-piece prosthesis blank which is constructed from a gum-colored material and a tooth-colored material (32), in particular in each case on a plastic base. It is characterized by being connected to each other at connecting surfaces, having an interface between the gum-colored and tooth-colored materials. This interface, when viewed along the connecting surfaces has an undulating shape and viewed in the vestibular direction has a radial shape. In order to finish the dental prosthesis, a CAD/CAM device determines the exact course of a gingival line, based on patient-specific data, and produces the prosthesis.

摘要： The present invention relates to an apparatus and method for three-dimensionally laminating a ceramic denture in a color-and-transmittance variable manner. A base slurry and a light transmissive slurry are mixed at a ratio regulated by a main controller according to a slurry ratio parameter datum, and then a slurry mixture is laid on a substrate by a laying module to form a slurry layer; next, the slurry layer is photocured by a photocuring module according to a laminated graphic under control of the main controller; in such a manner, the slurry layers are laminated and cured one by one so that a denture green body is formed; finally, the denture green body is sintered at a high temperature to form a ceramic denture. The present invention allows each slurry layer to exhibit different color and transmittance, resulting in quite natural gradation of color and gradation of transmittance.

摘要： A method for directly printing orthodontic and dental appliances on the teeth of a patient. The tooth is scanned with a scanner which is communicated with a computer controller configured to recognize the anatomy of the tooth. The surface of a tooth of the patient is then prepared in order to receive the type of appliance designated for the patient. Using image data from the print head, the computer controller prepares a three-dimensional blueprint or design of an appropriate orthodontic or dental appliance. The computer controller controls the type and amount of material that is distributed through the print head only when the print head passes over the recognized anatomy so as to directly print the corresponding appliance onto the tooth layer by layer as the print head makes successive passes over the surface of the tooth.
