Description

Adjustable occlusion positioning plate for occlusion reconstruction in child correction

Technical Field

The utility model belongs to the technical field of medical instrument, concretely relates to an adjustable interlock locating plate that interlock was rebuild in was rescued to children.

Background

Occlusion reconstruction in functional appliance treatment refers to changing the position of the lower jaw in the three-dimensional direction, extending or retreating the lower jaw, removing the reverse occlusion of occlusion alignment or opening the occlusal gap, triggering the reflection of neuromuscular, repositioning the lower jaw, and establishing a new coordinated occlusal-maxillofacial relationship. Occlusal reconstruction is an essential key step in the manufacture of functional appliances. Reconstruction of craniocortical surface of temporomandibular joint, craniofacial suture, erupted tooth and alveolar bone by the appliance in a new three-dimensional space is an important component of the function appliance mechanism. The position of the occlusal reconstruction is highly personalized and needs a doctor to determine according to the classification, severity, growth potential, appliance type, etc. of the malocclusion deformity of each patient. The upper and lower midlines are aligned in most cases, the sagittal aspect of the lower jaw needs to be extended or retracted to different degrees to be covered shallowly, aligned or covered excessively by 1-2mm repeatedly, the vertical height of the upper and lower anterior teeth may not exceed the spacing of the closed teeth or greatly exceed the spacing of the closed teeth by 5mm, but the clinical vertical occlusion of the anterior teeth is opened by 2-6cm more frequently.

Chinese patent CN202122372920.4 discloses a device for determining the positional relationship between the upper and lower jaws of the oral cavity, which carries out occlusion reconstruction of the fabrication of the oral appliance for obstructive sleep apnea syndrome through a three-way chute and an anterior tooth positioning groove, and can relatively accurately carry out reconstruction of the three-dimensional occlusion relationship of the anterior appliance. Functional correction in children may require mandibular advancement or withdrawal depending on the type of patient. Simultaneously, incisor rigidity V-arrangement maintenance groove is not applicable to the children that need be rescued (the malocclusion that needs to be rescued is many with the torsion of tooth uneven and dislocation), and this product structure is complicated, and the great unsuitable children of combined module volume, and easily arouse children and fear. Meanwhile, the complex slider combination device is not favorable for clinical disinfection and sterilization requirements.

The above-mentioned problems should be considered and solved in the recording of the maxillomandibular position in the three-dimensional direction of the child's bite reconstruction.

In the prior art, a doctor orders a patient to practice after determining an ideal personalized jaw position, the doctor uses a wax sheet with the thickness of 1mm to heat and fold, and then manufactures a wax jaw with the shape similar to a dental arch of the patient and the proper thickness on site, and the wax jaw is heated again to the proper thickness and then occluded and reconstructed by a method of biting the wax jaw by the patient. The specific method comprises the following steps: the patient is relaxed to do the lower jaw protrusion or retreat exercise by the patient after explaining the ideal jaw position, the exercise is maintained for 2 to 3 minutes, the patient can be accurately positioned by repeating the exercise for 2 to 3 times, the horseshoe-shaped wax dike with the shape similar to the dental arch and the proper thickness is manufactured on site, the patient is ordered to actively engage or the patient is ordered to stop engaging after the wax dike is induced to be correct in the three-dimensional direction by assisting a manual, and the patient is immediately flushed with cold water until the patient is completely cooled after taking out the wax dike.

The prior art then suffers from the following disadvantages:

1. the children patients are mainly concentrated on 3-10 years old, the ideal jaw position indication of doctors cannot be understood necessarily, and the children patients may not cooperate with each other due to low age, discomfort and the like in the process of guiding the manipulations of the operators, so that the occlusion reconstruction cannot be carried out.

2. The infant needs to be exercised repeatedly, a doctor needs to make a wax jaw after heating and softening a wax sheet on site, the whole process is time-consuming, and the occlusion position guides the height matching of the patient.

3. The wax levee can operate for a limited time after being heated and softened, and the wax jaw is easy to deform before being cooled and hardened. The infant patient often fails to control the biting force and may bite the wax levee askew. The occlusal reconstruction fails because of over-occlusion caused by too large occlusal force or over-large occlusal force due to inadequately insufficient occlusal force.

4. The wax sheet can not resist high temperature and high pressure or chemical soaking, and the disinfection and sterilization are relatively difficult.
