Invisible mandibular advancement orthotic method and invisible orthotic apparatus based on same

Abstract

Theinvention discloses an invisible mandibular advancement orthotic method and an invisible orthotic apparatus based on same. The invisible mandibular advancement orthotic method comprise the following steps of acquiring related conditions of to-be-treated teeth; determining a target advancement position of a maxilla and a target advancement position of a mandible; according to a target distance of mandibular advancement relative to maxilla advancement, advancing the mandible from an initial position of the mandible to the target position of the mandible through a plurality of steps; according to tooth arrangement conditions, adjusting and controlling each tooth in an tooth arch in a three-dimensional direction including a horizontal direction, a vertical direction and a sagittal direction; determining a target position to which a first molar of the maxilla moves to according to a target distance of mandible advancement; and moving the first molar of the maxilla from an initial position to the target position. The invisible orthotic apparatus comprises an invisible orthotic three-dimensional dental brace, a mandibular advancement slant tooth fit pad, and an anterior tooth press down auxiliary guide board. The invisible mandibular advancement orthotic method and the invisible orthotic apparatus based on the method can advance the mandible and push distal molar movement simultaneously, and improves the orthotic efficiency of angle class II malocclusion cases.

Description

technical field [0001] The invention relates to the technical field of stomatology, in particular to a method for invisible correction of mandibular advancement and an invisible correction device based on the method. Background technique [0002] Usually, in addition to mandibular retrusion, Angle's class II malocclusion patients are often accompanied by symptoms such as maxillary protrusion, narrow dental arch, and deep overbite. For such patients in the growth and development stage, the more effective treatment method is to first apply a functional appliance to guide the mandible forward, then move the maxillary molars away, and then retract the anterior teeth to establish an Angle I occlusal relationship. [0003] For patients with mandibular retrusion deformity in the growth and development stage, a variety of leading mandibular functional appliances are commonly used clinically to improve the relationship between the upper and lower jaws. Orthopedic methods are used to...

AI Technical Summary

Problems solved by technology

But this appliance still has the following deficiencies: 1. For cases accompanied by the advancement of maxillary molars and crowding of the upper anterior teeth, the appliance can only lead the mandible and align the teeth, but cannot correct the teeth in the dental arch. Adjust and control the three-dimensional directions of horizontal, vertical, and sagittal directions, and the molars cannot be moved away at the same time; 2. Patients need to be treated in stages, which makes the treatment period long and low in efficiency; 3. For patients with deep overbite at the same time In some cases, especially in an open mandibular preocclusion, anterior tooth depression is less effective

Moreover, the comfort of the traditional molar remote movement device is poor, and the success of its treatment depends to a large extent on the cooperation degree of the patient.

To solve the problem of protruding teeth, it takes a long course of treatment and effort
