Description

Technical Field

[0001] The utility model belongs to the technical field of medical appliances, in particular to an average value full-mouth edentulous tray. Background Art

[0002] With the change of population structure in my country, the number of elderly people is gradually increasing, and there will be more and more patients with full mouth edentulousness. In recent years, with the improvement of people's quality of life and the increase of economic income, more edentulous patients also need to replace the second and third sets of full mouth dentures. I really feel that the number of patients suffering from edentulous jaws is increasing day by day. A suitable full mouth tray is needed to make full mouth dentures. The average full mouth edentulous tray is also a universal full mouth edentulous jaw tray. The tray is designed by taking the average value of the inter-jaw distance of edentulous jaw patients, so that the impression material is quickly and evenly compressed, and the impression material flows to all corners, so as to take out a more accurate and suitable full mouth model. The average full mouth edentulous tray is relatively simple and efficient to make impressions. There are three clinical models of universal edentulous jaw trays, namely large, medium and small. Men choose large size, because gay men have wider dental arches and crowns and fuller bones, so most patients choose large size. Women usually choose medium size, and patients with tooth defects caused by trauma or congenital reasons choose small size.

[0003] Most of the full-mouth edentulous trays we use now are imported from Europe, America, Japan, etc., and many problems will occur when they are clinically applied to the oral cavity of the elderly in my country. Eating is chewing, which awakens the vitality of the brain and prevents brain aging. Only by tasting food and enjoying life with high-quality full-mouth dentures can the elderly feel the happiness of life. Patients suffering from edentulous jaws are eagerly looking forward to high-quality medical services. Find a full-mouth tray suitable for Chinese people, take out more precise impressions, take out the anatomical landmarks and suitable base edges we need, and a suitable full-mouth edentulous tray provides possibilities for more elderly patients without open jaws.

[0004] In addition, by providing overflow holes on the base plate, cheek wall and tongue baffle of the full-mouth edentulous jaw tray, excess impression material can be squeezed out conveniently, thereby reducing the impact of excess impression material on the impression. However, in practice, it is found that most of the excess impression material directly overflows into the patient's mouth through the overflow holes, causing certain discomfort to the patient and making it inconvenient to clean and collect.
