Lower incisor extraction for dental camouflage

Lee, Won You; Lee, Young Taek

Abstract

There is a variation in the range of normal occlusion, and we must fit our treatment to the needs of each patient. If the upper or lower incisors are congenitally missing, malformed, or crowded, the extraction of the incisor has some advantages over the extraction of premolars and nonextractions. The advantages are l) simple mechanics, 2) reduced treatment time, 3) less relapse tendency, and 4) fewer facial profile changes. In order to decide which incisor should be extracted, we must consider certain factors: l) discrepancies in anterior arch length, 2) anterior tooth ratio, 3) periodontal and tooth health condition, and 4) the relationship between the upper and lower midline. Diagnostic set-up can be helpful to plan the treatment and show us the post treatment result.
