Glazing adjacent surfaces is also called slicing. Within a certain range, the adjacent parts between the teeth are slightly ground off to obtain the gap where the teeth can move, and then the gap is closed by correction.

Normal enamel removal is not too harmful, but it is usually sensitive and prone to dental caries, which requires good care and is irreversible. The advantage of adjacent enamel removal is that the crowding gap of dentition is 2. Five to five. The marginal case of 0mm is a difficult problem in clinical correction. Simple arch expansion can easily lead to dental arch protrusion and recurrence. Other conventional orthodontic techniques are difficult to achieve molar recession without micro-implant anchorage, and dental orthodontics can easily lead to excessive recession of front teeth, resulting in uneven face.
