Description

Functional appliance capable of dynamically monitoring correction force value based on flexible electronic system and preparation method thereof
Technical Field
The invention belongs to the technical field of tooth correction, and particularly relates to a functional corrector capable of dynamically monitoring a correction force value based on a flexible electronic system and a preparation method thereof.
Background
In 1982, Clark, scotland scholars, first proposed a double-pad appliance as an important component of a functional appliance, which plays an important role in the early correction of juvenile malocclusion deformity, and can fully utilize masticatory muscles to generate corrective force, transmit the force to bone tissues, stimulate mandible growth and limit maxilla growth. The traction force generated by the inclined guide plate continuously stimulates the jaw bone and promotes the bone tissue adaptability reconstruction. However, the amount of tractive effort generated by the appliance ramp guide, typically derived from the experience of the clinician, is currently a dispute, 32429. Generally, the sum of the mandibular advancement amount and the vertical opening amount is 8 to 10mm, and it is also believed by scholars that the sum of the mandibular advancement amount and the vertical opening amount is not more than 12mm, which is a safe traction force.
The Anurag scholars take a malocclusion patient as a research object to simulate the joint stress condition when the functional appliance opens the occlusion and guides the lower jaw forwards. It has been found that when the mandible is advanced, there is greater tensile stress on the superior posterior aspect of the condyles, and as the bite height opens up, the tensile stress on the condyles increases. The Kanghong et al have found that the change of the tensile stress in the range of 5% strain of the articular disc belongs to the physiological strain and the tensile rigidity is 9.04-13.65MPa by the uniaxial tensile test of the articular disc. Excessive stress or abnormal directional stress can lead to degeneration of the joint disc, and the occurrence and development of temporomandibular joint disorder. Studies by scholars have found that the greater the degree of displacement of the articular disc, the more evident the structural changes of the articular disc and the more severe the symptoms of the temporomandibular joint disorder.
Therefore, in order to avoid the excessive stress of the joint area, it is necessary to dynamically monitor the force applied to the mandibular area by the functional appliance, so as to avoid the joint lesion caused by the excessive stress of the temporomandibular joint area, and simultaneously promote the reconstruction of the temporomandibular joint area under the stimulation of proper traction force, so as to realize the early correction of the malocclusion deformity and the beautiful occlusal surface effect.
