A retrospective comparative cephalometric evaluation of non-extraction multiloop edgewise archwire and bicuspid extraction therapies in anterior open bite treatment.

Objectives: This study aimed to compare treatment efficacy and cephalometric outcomes between extraction and non-extraction MEAW therapies in non-growing open-bite patients.

Materials And Methods: 22 Multiloop Edgewise Archwire MEAW patients (11 males, 11 females) and 15 bicuspid extraction patients (3 males, 12 females) were selected according to a strict inclusion criterion. Comprehensive data collection related to age, sex, Cervical Vertebral Maturation CVM staging, and severity of the Anterior Open Bite AOB (1 = 0-1 mm; 2 = 1-2 mm; 3 = > 2.
