Disease analysis: Hello, your condition should be treated in a plastic surgery hospital. Generally, only surgery can be used, and the effect is very good. I can only introduce you to the basics. You have to make your own decision. There are four kinds of gum exposure.

1, for short teeth (insufficient eruption):

The ratio of length to width of teeth in this kind of patients is obviously uncoordinated (the width of central incisors is about 75%~80% of the length), and simple periodontal crown lengthening (gingivoplasty) or periodontal crown lengthening combined with veneer and porcelain crown can be used for restoration. 2. For tooth deformity:

Malocclusion, such as protrusion of bicuspid arch and deep overbite of anterior teeth, may cause gingival smile. Generally, it can be corrected by simple orthodontic treatment, but it takes about 2 years (depending on the complexity of malocclusion).

3. For patients with short upper lip:

Aesthetically, the importance of lips on the face is second only to that of eyes. The upper lip height of oriental males is 17.57mm, and that of females is15.70mm. Anything below 12mm is a low lip. Lip correction surgery can be used to increase the height of the upper lip (the height of the lip refers to the height of the skin of the lip, excluding the red lip), as follows:

Extraoral method: the height of upper lip can be increased immediately by using triangular flap pedicled with double alar, but there is scar on the bottom of upper lip nose.

Intraoral method: make an incision in the vestibular sulcus of maxilla, find out the quadratus muscle of the upper lip on both sides, cut off this muscle, extend the mucosal tissue of the frenum appropriately, and relax the upper lip; This method can not increase the height of the upper lip in the near future, and it must be effective through long-term exercise of the patient's labial muscle function.

4. For adult patients with severe maxillary protrusion:

Orthognathic surgery, such as LeFort osteotomy, is usually used to retreat the protruding maxilla to its normal position. This kind of operation must be carried out through accurate measurement and special surgical instruments, which has great trauma, long recovery time, certain risks and high requirements for doctors and hospitals. Orthognathic surgery has the power to turn decay into magic, which can greatly improve the appearance of patients.

Suggestion: Choose a regular hospital and wish you a speedy recovery.
