Bonding positioning device convenient to dismantle

Technical Field

The invention relates to the field of orthodontic correction, in particular to a splicing positioning device convenient to detach.

Background

In current orthodontic treatment, direct bonding is generally used when bonding brackets to tooth surfaces. Since the prior art direct bonding technique is a manual bonding based on the experience of the doctor, this method is highly dependent on the skill of the doctor for bonding and the visual observation. The working intensity is high, the efficiency is not high, the repeatability is not good, and the accuracy is not ideal. Nevertheless, due to its intuitiveness, it remains widely used in clinical practice by most orthodontists.

To overcome these disadvantages of the direct bonding technique, an indirect bonding technique has been developed. Indirect bonding techniques place the brackets in a transfer device, through which the brackets are transferred to the tooth. At present, most of the transferring devices in the market are difficult to take down the transferring devices from the tooth surfaces through orthodontic tools after bonding brackets on the tooth surfaces, the transferring devices need to be manually operated by an orthodontist to take down the transferring devices from the tooth surfaces, but the oral environment is narrow, the orthodontist does not have a large operable space to take down the transferring devices, a large amount of time and energy are generally needed to be spent, the working strength and the operating time of the orthodontist are increased, and the original purpose of reducing the working strength of the orthodontist by indirect bonding is overcome. And the orthodontic experience of the orthodontic correction patient is poor, so that an orthodontic doctor usually abandons an indirect bonding technology, and adopts a direct bonding technology to bond a bracket for the orthodontic patient.
