The main reasons for deep composite include overgrowth of anterior alveoli, underdevelopment of posterior alveoli, and different correction methods. The deep composite flat guide or support nail can also be divided into situations, such as minor deep composite and auxiliary tools required for deep composite.

Let's look at the correction method of deep composite flat guide or anchorage nail

Let's see whether to use flat guide nails or anchor nails for deep composite:

1、 Deep overlying caused by anterior alveolar overgrowth:

1. If it is mild deep overlap, that is, one degree of deep overlap, it can be improved by simply wearing an appliance;

2. If the second degree of deep occlusion is slightly stronger, it can be adjusted by pressing down the auxiliary arch, or by wearing a flat guide to lower the front teeth, lengthen the rear teeth, and open the occlusion;

Horizontal guide correction can be used for depth compounding

3. In case of strong deep occlusion of 3 degrees, the movement of teeth can be controlled through the supporting nails to lower the upper anterior teeth and open the occlusion;

But beauty ♀ good ♀ Netsize ♀ The editor reminds everyone here that you should know that the correction is a deep covering that will not achieve the effect of jaw attachment, because the correction can only change your tooth condition, and will not change your jaw shape;

But for some people with low mandibular angle, in other words, this is a national face. After correction, the rear teeth are raised to make the chin rotate backward, increasing the length of the mandibular angle by 1/3. Visually, there is a feeling that the chin is getting longer, and the Chinese face looks less square;

Anchoring nail can be used for the auxiliary correction of depth composite three degrees

2、 Deep overlying caused by hypoplasia of posterior teeth:

For the deep complex caused by insufficient posterior alveolar development and low height, the molar can be used to extend the posterior teeth backward to open the occlusion. If it is a fixed appliance, it can also be pulled with arch wire to lower the front teeth, raise the rear teeth and open the occlusion;

The difference between tooth deep complex and bone deep complex

Now, my friends know whether to use horizontal guide or anchorage nail for deep overlap. The tools used are naturally different due to the different situations of deep overlap. Let's compare the correction methods of mild deep overlap, deep overlap of two degrees, and deep overlap of three degrees.
