The Importance of Dental Appliances for Oral Commissure Reconstruction in Trauma-Induced Microstomia: A Clinical Report.

Reconstruction of the oral commissure is necessary after trauma, pathological resection, or electrical, chemical, or thermal burns. Using dental appliances is strongly recommended to prevent microstomia in victims with oral commissure injury caused by burns. These appliances can be modified from dynamic to static for more patient comfort during the healing period and used in trauma patients to prevent rounding of the labial commissure. Preventing relapse of microstomia and forming acute angles at the corner of the mouth are 2 optimal goals when performing this surgery.
