Management Of Skeletal Class Ii Malocclusion With Twin Block And Headgear: A Case Report

Background. The main concern of patients and their parents seeking orthodontic treatment has always been the sagittal relationship between the jaws and dentition. The most commonly observed sagittal problems are skeletal class II maxillomandibular relationship which affects about one-third of the examined patients who seek orthodontic treatment. This case report demonstrates the use of the Twinblock appliance and high-pull headgear in a skeletal Class II Division 1 patient with a prognathic maxilla and a retrognathic mandible. A 9 year old male patient reported to Department of Paediatric and Preventive Dentistry with a chief complaint of forwardly placed upper front teeth. On extraoral examination, it was found that the patient had a convex profile, incompetent lips, increased maxillary anterior teeth visibility, acute nasolabial angle, receded chin and deep mento labial sulcus. Superimposition of Post treatment with pre-treatment lateral cephalograms showed a reduction in the sagittal discrepancy. With the retraction and intrusion of maxillary anteriors by the use of head gear along with mandibular advancement by the use of twinblock gave the desired result.
