The answer is as follows: 1. For adults, what is the most effective and safest corrective operation for alveolar bone protrusion? The most effective treatment is orthodontics-orthognathic therapy, and the operation is not 100% safe. At present, the "anesthesia accident" can't be controlled at home and abroad, but the incidence is very small, 15000. 2. What is the therapeutic effect of this operation? Will there be sequelae? The effect is positive, and the only sequela is that very few people will have numbness of their lower lips. 3. Treatment time? 2 years 4, treatment costs? The cost of surgery is about 30,000-40,000, and the cost of correction is 25,000. Would you please estimate the degree of improvement according to the image data (I have never made a special film) and age? Not too old
