Embodiment Construction

[0057] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0058] Step 1) Obtain the patient's initial dental model, which includes the 3D digital model data of the upper and lower dentition of the teeth, and record its initial relative position as P0. The patient's initial dental model can be obtained by intraoral scanning of the patient, or by A silicone impression of the patient is taken, followed by an impression or plaster scan. The initial relative position P0 of the model reflects the patient's current occlusion in the mouth.

[0059] Step 2) Repositioning of the mandible of the patient. According to the initial relative position P0 of the model, a mandibular repositioning model P1 is determined.

[0060] For the determination of the mandibular repositioning model of a certain patient, the purpose is to adjust the position of the mandible so that it can reach the normal anteroposterio...

Abstract

The invention discloses a method for preparing an appliance for abnormal mandibular repositioning. First, obtain the patient's initial dental model, and the occlusal relationship of the upper and lower dentition in the initial dental model is used as the initial relative position of the model; after repositioning the patient's mandible according to the initial relative position of the model, the mandibular repositioning model is determined; according to the mandibular repositioning model, design Maxillary molar jaw pad group and guiding slope model group, the printed model group is obtained after the structure of the maxillary molar jaw pad group and guiding slope model group is fused; the orthopedic accessory model group that is bonded to the labial or lingual surface of the teeth is designed; the mandibular The repositioning model, the printing model group and the orthotic accessory model group A are combined to obtain the maxillary model and the mandibular model through 3D printing, and the printed model is formed and cut by hot-pressed film to obtain the mandibular repositioning orthosis. The invention realizes invisible correction and functional correction at the same time in the mandibular repositioning correction process.

Description

technical field [0001] The invention belongs to the field of orthodontics, and in particular relates to a method for preparing an orthodontist for mandibular abnormal repositioning. Background technique [0002] In the classification of malocclusion in the field of orthodontics, in addition to the crowding of the dentition, the skeletal class II patients also have abnormal development of the mandible, and the development of the mandible is set back relative to the process of the maxilla. In this state, the first molars exhibit a distal relationship, and such patients have symptoms of mandibular retrusion. For patients with skeletal class III, in addition to the crowding of the dentition, the development of the mandible is in a state of protruding relative to the maxilla, and the first molars are in a mesial relationship. Such patients have symptoms of mandibular hyperplasia. . Bone deformities have a great influence on the facial appearance of patients. [0003] The corre...
