In-depth science on self-ligating braces: the differences, principles and advantages of metal self-ligating brackets

Metal bracket correction can be divided into two types, self-ligating and non-self-ligating. Regarding self-ligating braces correction, many dental friends have a vague understanding, so today we will do an in-depth science popularization of self-ligating bracket correction. Five questions and five answers to solve the doubts of dental friends.

1. What is the force-adding principle of self-ligating brackets?

The principle of corrective force application of self-ligating brackets is to bond the brackets to the teeth, and then use the tensile force of the orthodontic wire to displace the teeth in a predetermined direction. The main force-applying principle is the same as that of non-self-ligating brackets, but the difference is that it can reduce The effect of friction and force in non-self-locking will be greater.

2. How to open the self-ligating bracket? How to close it?

Under normal circumstances, self-locking bracket correction cannot and is not recommended to be opened by yourself. If there are abnormal circumstances that require the brackets to be opened, it is better to go to the hospital and have a specialist open and adjust them. Because the tightness of the steel wires in the self-ligating brackets is adjusted by the doctor, opening them without authorization may affect the release of force, thereby affecting the orthodontic process.

3. Will self-locking brackets adjust automatically? Can they tighten automatically?

Self-ligating bracket correction does not automatically adjust or tighten. Dental friends can go to the hospital for follow-up consultations according to the time and schedule required by the doctor. The doctor will check the tooth displacement and tighten it manually.

4. Is the correction time of self-ligating brackets shorter than that of non-self-ligating brackets?

Under the same conditions, the correction time of self-ligating brackets is indeed shorter than that of non-self-ligating brackets, and the correction speed is relatively faster. This is mainly because self-ligating bracket correction reduces the friction of non-self-ligating correction rubber bands or wires, resulting in greater pulling force. At the same time, the follow-up time period for self-ligating orthodontics is relatively slow. Generally, follow-up visits are once every 2-3 months, which is more time-saving.

5. What are the differences between self-ligating brackets and non-self-ligating brackets?

Although they are both bracket corrections, the difference between self-ligating and non-self-ligating is still relatively large:

The fixing methods are different: non-self-locking ones use traditional ligature wire or rubber bands to fix them, which are easy to hang on the mouth and are not ideal in terms of comfort and appearance. The fixation method of self-locking bracket correction is locking plates, which avoids a series of problems caused by ligature wires and provides a better experience.

The follow-up time is different: the follow-up visit period of non-self-ligating correction is about 6-8 weeks shorter than that of self-ligating correction. In the entire orthodontic cycle, self-ligating correction can require about 4 to 5 fewer follow-up visits than non-self-ligating correction, making it more economical. Save time and effort. Of course, the specific number of follow-up visits depends on the dentist’s orthodontic plan and the progress of teeth correction.

Oral hygiene maintenance is different: Regarding self-ligating and non-self-ligating braces, self-ligating bracket correction is relatively better at maintaining oral hygiene. Of course, this cannot be compared with invisible braces. Everyone still needs to compare at the same latitude.
