Tooth arrangement process for movable stent manufacturing

Abstract

The application relates to the field of dentures, in particular to a tooth arrangement process for movable stent manufacturing. The tooth arrangement process comprises the following steps: S1, establishing a tooth feature 3D database of standard teeth; S2, extracting oral cavity feature information of a patient; S3, arranging teeth: a, determining an occlusion relationship of an upper jaw frame; b, selecting proper artificial teeth; c, determining the center line of a dental cast ; d, arranging anterior teeth; e, adjusting adjacent the gap of every two adjacent teeth in the same row of the anterior teeth of the upper jaw and the lower jaw, and automatically generating a posterior tooth arrangement line according to the arranged anterior teeth; and f, arranging posterior teeth; S4, repairing a wax pattern: a, making wax covers a region, between the artificial teeth and mucous membrane transition , on the cast; and b, carving the wax pattern; and S5, arranging complete teeth: a, determining the relationship of the upper jaw frame; b, selecting proper resin teeth; and c, arranging the teeth on the principle of complete denture arrangement. The tooth arrangement process has the effect of improving the tooth arrangement attractiveness and individuation degree of the complete dentures.

Description

technical field [0001] The present application relates to the field of dentures, in particular to a tooth arrangement process for making movable brackets. Background technique [0002] At present, edentulousness is a common oral disease, mostly in the elderly, and the proportion of patients with edentulous jaws is relatively high. According to the "Third National Oral Health Epidemiological Survey Report", the 65-74 age group tested Among the 46830 people, edentulous patients accounted for about 6.82%. As our country enters an aging society, the number of patients with edentulous jaws will continue to increase. At present, among the oral restoration methods for edentulous patients, complete denture restoration is the most common and main method. [0003] In the process of making complete dentures, obtaining an artificial dentition that fits the patient's oral characteristics is one of the key steps to the success of the restoration. A good artificial dentition can effectiv...

Problems solved by technology

[0005] At present, there are two main commercial softwares that support full denture CAD. One is “Dental System” developed by 3Shape Company in Denmark, and the other is “DWOS Full Dentures” developed by Dental Wings Company in Canada. The former adopts the method of adjusting the overall dentition Obtaining complete dentures and artificial dentition lacks the degree of personalization. The latter adopts the arrangement of scattered teeth to design the dentition, but it mainly reflects the design principles of complete teeth of Europeans and Americans, and there is a certain deviation from the design requirements of Asian complete dentures.
