Abstract

A method for manufacturing a removable dental prosthesis using a three-dimensional (3D) printer includes receiving dental impressions of a patient obtained using a dental impression tray assembly, the dental impressions including a bite registration and at least a mandibular impression or a maxillary impression; receiving information related to the patient's jaw relations obtained using the dental impression tray assembly, the jaw relations including a vertical dimension and a centric relation obtained during the patient's single visit to a dentist; scanning the received dental impressions with a 3D scanner to provide data representative of an edentulous shape of the patient; generating a 3D model of the dental prosthesis based on the data and the received information related to the patient's jaw relations using 3D design software; displaying the generated 3D model on a display, allowing customization of the 3D model; and 3D printing the dental prosthesis according to the 3D model.

Abstract

Photo-curable compositions for artificial teeth and denture base and a method for manufacturing denture by a three-dimensional printing system are provided. The compositions include photo-curable organic compounds, surface modified nano-sized inorganic filler, photo-initiator, colorant, and stabilizer. The composition is in a viscous liquid state having 1500 - 5000 cps at ambient temperature and has a low viscosity of 50 - 500 cps at jetting temperature or dispensing temperature. The composition also has an excellent curing rate for three-dimensional printing. Using the compositions, denture having a distinctive denture base and a set of artificial teeth can be manufactured via an inkjet type or digital light process type three-dimensional printing according to Computer Aided Design (CAD) data.

Abstract

In a method of obtaining a gum impression of a patient's mouth and measuring jaw relations, a dental impression tray assembly including a lower tray and an upper tray to fabricate a denture, is used. The lower tray includes a first piece and a pair of second pieces and the upper tray includes a third piece and fourth piece. The method includes inserting the lower tray loaded with an impression material into the mouth to take an impression; taking out the lower tray from the mouth and cutting the impression material along a borderline between the first piece and the pair of second pieces; separating the first piece from the pair of second pieces; attaching an intra-oral tracer to the first piece and inserting the first piece, to which the intra-oral tracer is attached, and the third piece into the mouth to measure the jaw relations.

Abstract

A dental impression tray assembly includes an upper tray and a lower tray operable with the upper tray, and the lower tray includes a first piece configured to measure jaw relations of a patient's mouth and a pair of second pieces detachably attachable to the first piece. The first piece of the lower tray is inserted into the patient's mouth independently of the pair of second pieces of the lower tray to measure the jaw relations and to obtain a bite registration. After the first piece is connected to the pair of second pieces, the assembly allows a final gum impression of the patient's lower gum to be obtained.
