A positioning jig for positioning dentures

Abstract

The invention relates to the field of false tooth machining and refurbishment equipment, in particular to a locating fixture for locating a false tooth. Locating holes are formed in the bottom of thefalse tooth. The locating fixture for locating the false tooth comprises a base, an expansion supporting device and a telescopic clamping device; the expansion supporting device is arranged on the base and is embedded into the locating holes to support the false tooth; and the telescopic clamping device is arranged on the base and is used to clamp the outer surface of the false tooth. According tothe locating fixture for locating the false tooth, through the matching of the expansion supporting device and the telescopic clamping device, the false tooth is clamped in multiple directions, and multipoint locating mounting of the false tooth is realized; the locating fixture has the advantages of convenience in locating operation, low control difficulty and high locating accuracy; the expansion supporting device supports the false tooth, so that overall shape deformation of the false tooth due to stress after being clamped is avoided; and by adopting the telescopic clamping device for clamping, the fixing effect on the false tooth is good.

Description

technical field [0001] The invention relates to the field of denture processing and repairing equipment, in particular to a positioning fixture for positioning dentures. Background technique [0002] In recent years, with the continuous development of my country's economy and the continuous improvement of people's living standards, oral health problems have become an important factor affecting people's quality of life. Therefore, people pay more and more attention to oral health problems.

Problems solved by technology

[0003] Among them, for dentures, since the specific shape of dentures varies from person to person, dentures have the characteristics of complex curved surfaces, small structural dimensions, and low rigidity, which makes it impossible to use conventional fixtures to position dentures. Therefore, the current Denture processing and refurbishment is mainly carried out under the condition of manual hand-held, but it is difficult to guarantee the processing accuracy, and the work efficiency is also low
