Orthodontic positioning guide plate

Technical Field

The utility model relates to an orthodontic field, concretely relates to just abnormal location baffle.

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.

However, existing indirect bonding transfer devices generally do not hold the bracket securely, such that the bracket tends to fall off easily when transferring the bracket to the tooth. Therefore, the stability of indirect bonding is poor, so that the orthodontic doctor often needs to repeatedly mount the bracket on the transfer device for many times, the working strength and the operation time of the orthodontic doctor are increased, and the original purpose of reducing the working strength of the orthodontic doctor by indirect bonding is overcome.

And existing indirect bonded transfer devices are typically provided for square brackets, but do not require indirect bonded transfer devices for spherical brackets.
