Disclosed is a method for modeling a denture for a patient, where the denture comprises a gingival part and artificial teeth, wherein the method comprises providing a 3D scan comprising at least part of the patient's oral cavity, virtually modeling at least part of the denture using the 3D scan, obtaining virtual teeth to represent the artificial teeth, virtually modeling at least one of the virtual teeth to obtain a set of modeled virtual teeth and using a dynamic virtual articulator for simulating occlusion of the teeth set comprising the modeled denture and any teeth still present in the patient's mouth.

A method of making a dental restoration is provided. The dental restoration comprises a frame and a veneer. An inner veneer surface and an outer frame surface are adapted to be mated with one another to form the dental restoration. The method in particular comprises steps of (a) providing an outer veneer surface; (b) determining an outer frame surface, based on the outer veneer surface; (c) determining an inner veneer surface, based on the outer frame surface; and (d) providing an inner frame surface, based on a natural tooth surface. The method may be advantageous for rapid, precise and inexpensive manufacturing of a dental restoration.

A fatigue-resistant Nitinol instrument has a working portion in the deformed monoclinic martensitic state and an austenite finish temperature in the range of 40° to 60° C. Because the operating environment of the instrument is about 37° C., the working portion remains in the monoclinic martensitic state during its use. The relatively high austenite finish temperature and fatigue resistance is achieved by subjecting the nickel-titanium alloy to a final thermal heat treat in a temperature range of about 410° to 440° C. while the nickel-titanium alloy is under constant strain of about 3 to 15 kg. Further, the high austenite finish temperature is achieved without subjecting the alloy to thermal cycling to produce shape memory. Additionally, there are no intermediate processing steps occurring between obtaining a finished diameter of the wire or blank through cold working and the final thermal heat treat under constant strain.

The present invention relates to a clear aligner, a manufacturing method thereof, a traction device for a clear aligner, and an auxiliary tool for a traction device for a clear aligner. More particularly, the present invention relates to a clear aligner (10), a manufacturing method thereof, a traction device for a clear aligner, and an auxiliary tool (40) for a traction device for a clear aligner, wherein the clear aligner can improve orthodontic effects by increasing a correction force by traction of a clear aligner using an elastic band when it is impossible to correct teeth only with the clear aligner due to uneven teeth.
