Description

Limiter for bracket bonding

Technical Field

The utility model relates to the field of orthodontic treatment, in particular to a limiter for bracket bonding.

Background

At present, in the orthodontic treatment process of oral teeth, a fixing correction means is one of the most mature correction means, specifically, an orthodontic bracket is fixed on a tooth surface, an arch wire passes through an arch wire groove on the bracket, the arch wire is arranged in the bracket arch wire groove in a ligation mode or through a self-locking structure, correction force of the arch wire is transmitted to the teeth through the bracket, and the teeth are enabled to move in an expected mode, so that the aim of correcting the teeth is achieved.

Whether the positioning position of the bracket adhered to the tooth surface of the patient is accurate or not can directly influence the success or failure of correction. Accurate positioning of the bracket on the tooth surface is a precondition for correctly expressing an expected target and effectively controlling tooth movement, and improper bracket pasting positions can cause the problems of poor occlusion relationship, unparallel tooth root arrangement, poor contact of adjacent surfaces, food impaction and the like, so that the treatment effect is obviously influenced, and secondary bonding and treatment course extension are often caused.

At present, the bracket bonding mode is two modes of direct bonding and indirect bonding. Direct bonding is the most traditional bracket bonding mode, a doctor manually marks the expected position on the teeth, and then bonds the bracket to the marked position, the method is extremely dependent on the personal experience level and the technical operation level of the doctor, the bonding quality is unstable, the operation environment is limited to the doctor in a clinic, and the time at the chair is long.

The indirect bonding mode is bonding by adopting a bracket positioning guide plate. The bracket positioning guide plate is internally provided with a containing cavity capable of containing the bracket, the bracket is placed in the corresponding containing cavity, an adhesive is smeared on the bottom plate of the bracket, then the bracket positioning guide plate is buckled on the dental crown of a patient, and after being irradiated by the light curing lamp, the bottom plate of the bracket is adhered and fixed on the preset position of the dental surface. However, the current positioning guide has the following drawbacks: (1) The existing positioning guide plate wraps the outer surface of the bracket through the inner cavity of the positioning guide plate, the positioning guide plate is sleeved on the whole tooth and covers the whole tooth surface, the volume of the positioning guide plate is relatively large, the surface of the bracket is completely covered, the intraoral operation of a doctor can be influenced, and the irradiation and bonding operation of the light curing lamp are blocked. In addition, as the fluidity of the adhesive is not very good, the residual adhesive can only overflow to the tooth surface and can not flow to the gum for removal, and the residual adhesive overflowed to the tooth surface can be blocked by the positioning guide plate and is difficult to remove, so that the bracket position adhered to the tooth surface is inconsistent with the expected position, the adhesion deviation is caused, and the correction efficiency and effect are prolonged. (2) The positioning guide plate needs to be provided with a certain thickness, the strength is guaranteed to meet the requirement, so that the relative position relationship between the positioning guide plate and the bracket can be stable, and the accuracy of the bonding position is guaranteed. The requirement also makes the positioning guide plate difficult to remove, and the positioning guide plate often wraps the upper wing and the lower wing of the bracket (the upper wing and the lower wing extend in opposite directions), so that the operation difficulty of a doctor when tearing the positioning guide plate is great, and if the operation is not careful, the bonded bracket is easy to deviate from the original position, which is a time-consuming and labor-consuming work for the doctor.
