Embodiment Construction

[0058] The present invention will be further described in detail below with reference to the drawings and specific embodiments.

[0059] Step 1) Obtain the patient's initial dental model. The model 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 scanning the patient's mouth, or by Obtain the silicone rubber impression of the patient, and then obtain the impression or plaster scan. The initial relative position P0 of the model reflects the patient's current bite in the mouth.

[0060] Step 2) The patient's mandibular repositioning, according to the initial relative position P0 of the model, determine the mandibular repositioning model P1.

[0061] For the determination of the mandibular relocation model of a certain patient, the purpose is to adjust the position of the mandible to achieve the normal anteroposterior position of the maxilla. The posit...

Abstract

The invention discloses a preparation method of an appliance for abnormality repositioning of mandible. The method comprises the steps: firstly, obtaining an initial dental jaw model of a patient, wherein the occlusion relation of upper and lower dentitions in the initial dental jaw model serves as an initial relative position of the model; determining a lower jaw repositioning model after repositioning the lower jaw of the patient according to the initial relative position of the model; designing an upper molar jaw pad group and a guide inclined plane model group according to the lower jaw repositioning model, and fusing the structures of the upper molar jaw pad group and the guide inclined plane model group to obtain a printing model group; designing an appliance accessory model group adhering to the labial surface or the lingual surface of the teeth; and combining the lower jaw repositioning model, the printing model group and the appliance accessory model group A, printing through3D to obtain an upper jaw model and a lower jaw model, and forming and cutting the printed model through a hot pressing film to obtain the lower jaw repositioning appliance. In the process of lower jaw repositioning correction, invisible correction and functional correction are simultaneously carried out.

Description

Technical field [0001] The invention belongs to the field of orthodontics, and in particular relates to a preparation method of an appliance for abnormal repositioning of the mandible. [0002] technical background [0003] In the classification of malocclusion in the field of orthodontics, in addition to crowding of the dentition, there are also abnormal development of the mandible, and the development of the mandible is backward relative to the maxillary. In the state of the patient, the first molar shows a distant relationship, and such patients have symptoms of mandibular retraction. For skeletal class III patients, in addition to the crowding of the dentition, the development of the mandible is relative to the state of the maxillary extension, and the first molar shows a mesial relationship. Such patients have symptoms of overdevelopment of the mandible . Bone deformity has a great influence on the appearance of patients. [0004] The correction of skeletal class II and skele...
