Many dental friends are struggling with whether to correct. In fact, most of them are struggling about whether to extract teeth for correction. If I told you that it could be 5-7mm without extraction, would you believe it?

There are three ways to get clearance
1. Distal upright posterior teeth
Distally upright teeth can create gaps to ease crowding.
Generally speaking, we choose five, six and seven good teeth. If these three teeth can stand upright for 10 degrees, a gap of 7 mm can be obtained; When 5, 6 and 7 teeth are upright for 15 degrees, a gap of 7-10 mm can be obtained.
This is equivalent to our orthodontic extraction of four orthodontic teeth, because the adduction of the extracted four orthodontic teeth is about 7 mm.

2 teeth twist forward
Correction of mesial lingual torsion of molars will also lead to gap contact crowding.
Some customers twist their molars forward, and then we correct them to the correct position. There will be a gap of 3mm in front of the molars, and a gap of 6mm on the other side.

3. Pantograph dilatation
In fact, this method is very common. In addition to expanding the arch, space can be obtained, such as pulling out wisdom teeth and pushing molars. There are also many cases of this situation.

If your teeth just meet the above three types, the orthodontist you are looking for has rich experience. I think it can achieve orthodontics but does not need tooth extraction.
At present, several orthodontists in China are very powerful. When they do orthodontics again, their first consideration is not tooth extraction, but how to get more space without tooth extraction
Therefore, if you find a reliable doctor, you can collect 5-7mm without tooth extraction!
