Cross-joint correcting device matched with invisible correcting device
Technical Field
The utility model relates to an invisible correcting device, in particular to a crossing correcting device matched with an invisible correcting device.
Background
The bracket-free invisible appliance is a removable movable appliance formed by pressing a transparent film with the thickness of 0.8 mm, is favored due to the advantages of lightness, thinness, transparency, beauty, soft stress and the like, but has the characteristic of soft stress and the defect of insufficient force expression in certain type of mismatch correction. If the teeth are crossed, the teeth are mostly arranged on the last molar or a plurality of molars at one side or two sides, the upper molar crosses the outer side of the lower posterior teeth, the teeth lose the occlusion function, and the crossing occurs at the rear end of the dentition along with the over-sprouting of the related upper and lower teeth, and the occlusion is locked due to the over-sprouting growth of the related teeth, so the crossing is also called locking; the force of the invisible appliance is far from the correction requirement, so the invisible appliance is not an indication for correction. Aiming at the problems, the traditional correction method is to implant bone nails at the buccal side of the upper posterior tooth area, the buccal side of the lower posterior tooth area and lower posterior tooth area, press the upper and lower related posterior tooth areas down and simultaneously correct the type of the malocclusion by matching the bonding drag hooks on the buccal surface of the upper posterior tooth and the lower posterior lingual surface; however, the implantation of the bone screw is invasive, and the pulling hook is adhered to the buccal surface of the last molar of the upper dentition and the lingual surface of the last molar of the lower dentition, which adds great difficulty and challenge to the clinician.
