Functional appliance capable of dynamically monitoring correction force value based on flexible electronic system and preparation method of functional appliance

Abstract

The invention discloses a functional appliance capable of dynamically monitoring a correction force value based on a flexible electronic system and a preparation method of the functional appliance, and belongs to the technical field of functional correction. The functional appliance comprises a retention device, a flexible electronic chip system, a maxillary resin base, a mandibular resin base, a maxillary occlusal pad, a maxillary inclined surface guide plate and a mandibular inclined surface guide plate, the maxillary resin base is adopted to cover the palatal side of the upper jaw of the oral cavity, the mandibular resin base is adopted to cover the tongue side of the lower jaw, and the tail end of the retention device is embedded in the bases. The maxillary inclined surface guide plate is arranged on the maxillary occlusal pad and corresponds to the mandibular inclined surface guide plate, and stress between the maxillary inclined surface guide plate and the mandibular inclined surface guide plate on the two sides is monitored through a sensor; the functional appliance is manufactured by adopting a novel injection molding process, the retention device and the sensor are embedded in the resin bases to form an integrated structure, the correction force value can be dynamically monitored, damage to temporal-mandibular joints caused by overlarge correction force in the correction process is prevented, the appliance can be adjusted according to correction force data, and a child patient can wear the functional appliance comfortably.

Description

technical field [0001] The invention belongs to the technical field of orthodontics, and in particular relates to a functional orthodontic device based on a flexible electronic system that can dynamically monitor the orthodontic force value and a preparation method thereof. Background technique [0002] In 1982, Scottish scholar Clark first proposed the double splint appliance. As an important part of the functional appliance, the double splint appliance played an important role in the early correction of juvenile malocclusion. The muscles of mastication generate orthodontic force and transmit the force to the bone tissue, stimulating the growth of the mandible while restricting the growth of the mandible. The traction force generated by the inclined guide plate continuously stimulates the jaw bone and promotes the adaptive reconstruction of bone tissue. However, the traction force generated by the inclined guide plate of the appliance usually comes from the experience of c...
