AI Technical Summary
The existing fixed orthodontic appliances have a rigid connection between the upper and lower dental arches, which cannot be flexibly adjusted according to the patient's oral movement state. This results in poor wearing comfort, may generate excessive stress, affect the orthodontic effect, and the occlusal adjustment structure is not flexible enough to accurately adapt to the occlusal angle and orthodontic stage needs of different patients, increasing the treatment period and patient discomfort.
It adopts a compression spring and telescopic rod structure between the left and right maxillary blocks, combined with the elastic connection design of the upper and lower orthodontic components. Through the rotatable hinge structure of the upper and lower orthodontic components and the elastic fastening of the X-shaped rubber sleeve, it realizes the adaptive extension and contraction of oral movement and the flexible adjustment of the occlusal angle.
It improves the wearing comfort of the orthodontic device, reduces stress concentration, shortens the treatment cycle, reduces patient discomfort, can adapt to the needs of different orthodontic stages, and improves the orthodontic effect.
