Abstract

The invention relates to a jaw position recording tray and a method for determining a jaw position relation. According to the jaw position recording tray, the shape of the tray is matched with the oral cavity structure of an edentulous jaw patient; the tray comprises a base support and supporting tables which are respectively located at two sides of the base support; a tray handle connected with the base support is arranged at the front end of the tray; the tray handle is a flange inclining downwards and outwards; a supporting rod hole is reserved in a position, corresponding to the first molar of the upper jaw of the human body, of each supporting table; a screw joint mechanism is arranged in each supporting rod hole; and each screw joint mechanism is matched with a supporting rod with threads. The jaw position recording tray provided by the invention is reasonable in structural design, and can reduce the operation difficulty of a doctor for determining the jaw position relation during complete denture repair of the edentulous jaw patient. By using of the method for determining the jaw position relation through the jaw position recording tray provided by the invention, the jaw position relation can be determined by sequentially determining the plane, vertical distance and horizontal relations, and is easy in operation and accurate in jaw position recording.

Description

technical field [0001] The invention relates to stomatology, in particular to a jaw position recording tray and a method for determining the jaw position relationship. Background technique [0002] According to the fourth national oral health epidemiological survey report, the edentulous rates of the 55-64 and 65-74 age groups were 1.1% and 4.5%, respectively. If the terminal dentition has only a few residual roots or loose teeth that are not extracted, the prevalence of edentulousness will be even higher. Considering the overall aging of the population and the huge population base, there is still a great demand for restoration treatment of patients with missing dentition in dental clinics. [0003] Complete dentures (including implant overdentures) are the main way of clinical treatment for edentulous patients. In the restoration of complete dentures, a very critical and difficult link for beginners is to determine the jaw position relationship. At present, the common wa...
