Customized self-ligating bracket appliance and manufacturing method thereof

Abstract

The invention discloses a customized self-ligating bracket appliance and a manufacturing method thereof. The manufacturing method comprises the following steps: S1, acquiring digital dentition data of a patient, and acquiring an STL (Standard Template Library) model of teeth of the patient; and S2, segmenting a dentition model into single teeth by using drawing software in a computer, marking a clinical crown center point of each tooth, setting a clinical crown long axis, and performing digital tooth arrangement simulation according to requirements of a doctor and actual conditions of an alveolar base bone and a dentition of the patient. The customized self-ligating bracket appliance comprises a plurality of brackets and buccal tubes which are connected in series through arch wires, each bracket comprises a self-ligating bracket body, a bracket connecting body and a bracket bottom plate, each buccal tube comprises a buccal tube body, a buccal tube connecting body and a buccal tube bottom plate, the self-ligating bracket bodies and the buccal tube bodies are both prefabricated finished products, and two bracket wings are respectively fixed at the upper end and the lower end of each self-ligating bracket body. According to the invention, accurate customization is carried out according to the tooth form of a customer, so that no difference exists in the use process, and accurate orthodontic treatment is realized.

Description

technical field [0001] The invention relates to the technical field of orthodontic bracket manufacturing, in particular to a custom-made self-locking bracket appliance and a manufacturing method. Background technique [0002] Due to the influence of genetic factors or environmental factors, the incidence rate of malocclusion is as high as 70%, which will have a certain impact on the aesthetics, function and psychology of patients. In the orthodontic appliance for treating malocclusion, on the traditional straight wire bracket appliance, the data on each bracket is designed and manufactured based on the average data of the teeth of the population, and relies on the doctor's experience to directly bond and position with the naked eye Orthodontic treatment on the tooth surface and with a general-purpose arch wire. Since everyone has some differences in the shape of teeth, and the shape of the alveolar base bone is also different, this traditional bracket appliance and arch wir...
