To provide a dental set for open bite treatment, which can easily depress molars in a short period of time without causing extrusion of front teeth when it is necessary to depress molars in open bite treatment, thereby enabling open bite treatment. [Solution] The dental set for open bite treatment has a plurality of brackets (201) attached to the patient's maxillary or mandibular teeth, an orthodontic wire (11) attached to these brackets, and an intermaxillary elastic (400). When indenting a patient's maxillary molars, the intermaxillary elastic is stretched by attaching the orthodontic wire to the bracket attached to the crown of the maxillary canine from above and stretching it, then hooking it from below to the bracket attached to the crown of the mandibular canine, and further hooking it onto a bondable tube (202) attached to the crown of the mandibular first molar. The same applies when indenting a patient's mandibular molars.

The invention discloses a control method, system and equipment for improving the flatness of an orthodontic steel wire bent part and a medium. The core of the method is that after bending operation is executed, information reflecting the flatness of an orthodontic steel wire bending piece is obtained through a sensing module (such as a visual system), and based on the information, the steel wire rotation compensation amount or the side notch height compensation amount used for compensating the flatness is determined; and the compensation quantity is applied to the subsequent bending operation, and after the compensation parameters are associated with the corresponding bending process parameters, the compensation parameters are stored through a database with transaction processing capacity, so that the data consistency is ensured for subsequent automatic calling. Aiming at multi-step bending, the invention initiates a collaborative leveling strategy: height compensation is adopted for steps in a single bending direction to realize single-side coplanar, and rotation compensation is adopted for steps in different bending directions to realize overall coplanar. According to the method, a compensation object is expanded from the angle to the flatness for the first time, the inherent technical problem that the plane is poor due to deformation of a machine tool, uneven springback and the like is solved, the method is totally different from the technical problem solved by angle compensation, the bending precision and efficiency of the orthodontic steel wire can be remarkably improved, and the method is particularly suitable for manufacturing the orthodontic steel wire in the dental department.

The invention relates to an intelligent control method and system for bending production of a short and straight orthodontic steel wire and a storage medium. According to the method, on the premise that no external measuring device is used, a fixed safety threshold value L = A + a + b is set based on an inherent geometric dimension chain of bending equipment, the residual length G of the steel wire is estimated in real time through feedback of an encoder of a wire feeding module, and a comparison result of G and L serves as an automatic gating judgment basis. And when G is smaller than or equal to L-delta, early warning shutdown is triggered, and after confirmation of an operator, production is recovered only when recalculated G 'is larger than L + delta'. According to the method, through the synergistic effect of a sensorless geometric monitoring model and state machine closed-loop control, the technical effect that the machining failure rate of the tail end of the short and straight orthodontic steel wire is lower than 0.5% is achieved, and meanwhile the material utilization rate is increased to 98.2% or above; the technical problems of material waste, low production efficiency, insufficient reliability of an external sensor and the like in the prior art are effectively solved.
