Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings.

[0028] refer to Figure 1 to Figure 6 , a personalized orthodontic method based on shape-memory polymer archwires. After reconstructing a three-dimensional oral model including bones and teeth from the patient's CT data, it overlaps with the scanned and reconstructed data of the patient's dental model. According to the patient's tooth arrangement and skeletal conditions, formulate an orthodontic treatment plan, and obtain the final dentition arrangement after treatment; on this basis, select the bracket and determine the bracket position on each tooth; design the orthodontic archwire according to the bracket position, and its The shape matches the position of the dentition and brackets after orthodontic treatment, and is the shape in the memory that the SPM archwire needs to restore; during clinical operation, the archwire is placed in a certain temperature environment...

Abstract

An individuation orthodontic method based on a shape memory polymer (SMP) arch wire includes: reconstructing a three-dimensional oral cavity model comprising skeletons and teeth according to computed tomography (CT) data of a patient, overlapping the three-dimensional oral cavity model with data of a patient tooth model after being scanned and reconstructed, and drawing up an orthodontic treatment scheme and obtaining a final dentition arrangement after treatment according to a tooth arrangement and a skeleton condition of the patient; then selecting brackets and determining bracket locations of all tooth on this basis; designing an orthodontic arch wire according to the bracket locations, wherein the shape of the orthodontic arch wire is matched with a dentition and bracket locations after orthodontic treatment and is the shape needed to be recovered in the memory of the SPM arch wire; and enabling the arch wire to soften after placing the arch wire in a set temperature environment during the clinical operating process, and therefore the arch wire can be conveniently fixed in the bracket on a central tooth of a patient oral cavity. The individuation orthodontic method based on the SMP arch wire can effectively achieve individuation orthodontic and eliminate potential safety hidden dangers.

Description

technical field [0001] The present invention relates to an orthodontic method. Background technique [0002] Fixed oral orthodontics is aimed at tooth alignment deformity or malocclusion (occlusion is a word, the same below), using orthodontic devices composed of arch wires, brackets, etc., to apply mechanical orthodontic force and torque to the teeth, and adjust the facial bones, teeth, etc. The balance and coordination between the maxillofacial and maxillofacial muscles will improve the facial shape, align the dentition and improve masticatory efficiency after a period of orthodontic treatment. At the beginning of the 20th century, American dentist Edward Angle, known as the father of modern orthodontics, began to design dental appliances. In 1928, he introduced the square wire arch orthodontic technology, which laid the foundation of modern orthodontics. In 1970, American orthodontist Andrews proposed six criteria for the best natural occlusion, and invented the straight...
