Description

Appliance for correcting and curing diseases

Technical Field

Background

With the gradual development of the bracket-free invisible orthodontic technology, the invisible orthodontic device has the characteristics of convenient taking and wearing, easy clinical use, being beneficial to the sanitary cleaning of the oral cavity and the like, so that the bracket-free invisible orthodontic technology is more and more popular.

In the process of correcting teeth, the integral movement of premolars and molars is always a difficulty of invisible correction technology, the requirement of the integral movement is that crowns and roots of the teeth move together to a target position, the movement distance is completed according to the requirement of a doctor, and at the moment, the teeth need to act as a pair of force couples. The root is disturbed by the periodontal tissue, so that an increased force component is required to move the whole body against the resistance of the periodontal tissue. Because the tooth root is covered by the alveolar bone and the periodontal tissue, the correction force can only be applied to the tooth crown when correcting the teeth, which causes that the center of the resistance of the periodontal tissue and the center of the correction force generated by the corrector cannot coincide, and the corrector and the accessories need to be adjusted by the correction doctor by experience, so that the final resultant force of the correction force and the resistance points to the expected correction position. This may cause some probability of error in designing the appliances and attachments such that the resultant direction of the appliance force and the resistance force is not the intended direction of tooth movement, possibly resulting in overall movement failure.

Especially, most of patients' premolar tooth crown surfaces are all arc surfaces, when a horizontal rectangular accessory is used, the height of the middle part of the accessory cannot be guaranteed, when the arc height is higher, the height of the middle part of the accessory is only 0.1-0.5 mm, the accessory with the height can influence the stress state of the tooth and the wrapping property of the appliance, and the accessory moving effect is weakened.

In view of the above situation, it is necessary to design a horizontal arc-shaped attachment to improve the correction efficiency, to control the movement of the premolars and the molars more precisely, and to match the correction force generated by the attachment with the correction device to differentiate and balance the resistance generated by the tooth environment, to maintain the target movement direction, and to avoid the inclination and movement failure of the premolars and the molars caused by the attachment and operation.
