INTRODUCTION. ; For an overdeveloped chin (an apparent prognathism, but no class II maloclussion), the treatment consists of a mentoplasty or chin reduction surgery. There are different categories of malocclusion: Class 1 malocclusion is the most common. Treatment by maxillary protraction is effective in Class III patients with an . Class II Division 2 is where the maxillary anterior teeth are retroclined and a deep overbite exists. Occasionally, orthodontists encounter traumatic loss of maxillary incisors in growing patients.
