Description

Self-adaptive indirect bracket pasting bracket

Technical Field

The invention relates to the field of bracket pasting, in particular to a self-adaptive indirect bracket pasting bracket.

Background

At present, in the orthodontic treatment process of oral teeth, an orthodontic bracket is fixed on the tooth surface, an arch wire passes through an arch wire groove (also called a square wire groove) on the bracket, the arch wire is directly ligated into the bracket arch wire groove through a ligation rubber ring or a ligation wire, the correction force of the arch wire is transmitted to the teeth through the bracket, and the teeth generate expected movement so as to achieve the purpose of correcting the teeth. The bracket has strict requirements as to the attachment position on the tooth, since this is an important factor affecting the orthodontic effect. The traditional bracket pasting position selection method has two types, one is to mark the tooth according to experience and then paste, and the pasting effect is greatly influenced by the skill level of a doctor. Moreover, the method can only be carried out by doctors specialized in clinics, and inconvenience is brought to patients and doctors in the process of back and forth correction. In addition, in the process of placing the bracket, the bracket has small volume and limited operation space in the oral cavity, so that the treatment time is greatly prolonged, the extremely poor treatment experience is brought to the patient, and the time is wasted.

Chinese patent CN201710993718.9 discloses a bracket bonding positioner, a manufacturing method thereof and a bracket positioning method, the technical scheme has the following advantages that a computer is used for simulation creation of the bracket bonding positioner and simulation matching is performed, thereby reducing the discomfort of direct operation in the oral cavity of a patient, optimizing the treatment environment of the patient and simplifying the whole treatment process. The matching opening is simulated, so that the mounting position of the bracket can be accurately set, and operations such as taking a tooth model mark and the like are not needed to be carried out on site. During the entire creation of the socket positioner, the patient need only provide a three-dimensional scanned prototype of the oral teeth to the practitioner to complete the preliminary preparation. Provides possibility for commercialization and flow line production. However, in the operation process, because the shape and the position deviation of human teeth are large, manual adjustment is sometimes needed, so that the installation bottom plate and the bracket are required to have high degree of freedom, so that the adjustment is convenient, and meanwhile, the whole installation mechanism also has the characteristic of being capable of simultaneously installing.
