Description

Auxiliary device and correction method for improving malocclusion

technical field

The invention belongs to the technical field of oral orthodontics, and particularly relates to an auxiliary device and a correction method for improving malocclusion.

Background technique

Common malocclusions in clinical practice include posterior locking, molar elongation, and anterior functional crossbite.

Posterior locking, which can occur unilaterally or bilaterally, is common in the upper and lower premolar and second molar areas. Posterior occlusion can be divided into posterior ortho-occlusal and posterior cross-occlusion. The main clinical manifestation of posterior ortho-occlusal is that the buccal cusps and buccal slopes of the lower posterior teeth are occluded on the lingual side of the lingual tips and lingual slopes of the maxillary posterior teeth. The main clinical manifestation of posterior cross-occlusion is that the lingual tip of the posterior teeth and its lingual slope are occluded on the buccal tip of the upper posterior teeth and the buccal slope of the buccal slope, and there is no contact between the upper and lower posterior occlusal surfaces. As shown in Figure 5, in order to release the locking of the posterior teeth, the straight wire orthodontic technique is often used, and the glass ion occlusal surface of the posterior teeth is raised to cooperate with interactive traction. The risk of dental arch deformation and vertical loss of control.

Elongation of molars is often caused by long-term loss of posterior teeth leading to elongation of the opposite teeth, as shown in Figure 6. Although the use of implant nail anchorage technology to assist in lowering the molars can achieve good results, the patient faces the risk of implant nail loosening and falling off, resulting in the failure of orthodontic treatment.

Functional crossbite is caused by the labial inclination of the mandibular anterior teeth, or the lingual inclination of the maxillary anterior teeth, or a combination of the two, or individual tooth interference, and poor bite habits, such as protruding the mandible and forcing anterior displacement of the mandible, resulting in The anterior crossbite and the molars are Angle class III occlusion. Clinically, it is mostly manifested as functional mandibular displacement, with muscle position and tooth position imbalance. The mandible can be retracted manually to incision, and the patient can also retract the mandible by himself. As shown in Figure 7, for functional anterior crossbite, the traditional straight wire orthodontic technique mostly directly uses Class III traction to correct the anterior crossbite, and cooperates with the posterior occlusal surface elevation, but this method may cause the maxillofacial elevation material to fall off repeatedly. , Individual posterior teeth are not uniformly stressed.

Occlusion of posterior teeth, elongation of molars, and functional cross-occlusion of anterior teeth will not only cause different degrees of occlusal interference, but also seriously affect the patient's masticatory function, temporomandibular joint health, and facial aesthetic symmetry, and even lead to some patients. Psychological disorder occurs.

To sum up, when metal braces are used to correct malocclusion in the prior art, the height pads and implant nails are easy to fall off, resulting in poor correction effect and long correction time.
