Aim and objective: Correction of skeletal class II malocclusion by using myofunctional therapy. Background: B.R, a 12-year old female, reported with the chief complaint of irregularly placed teeth. Clinical examination and analysis of records showed that she had an Angle's Class I molar relationship on a Class II skeletal base with retrognathic mandible and deep mentolabial sulcus. There was reduced vertical proportion. Growth pattern was horizontal. There was increased overjet with lower central incisors missing. Transposition between 42 and 43 was seen. Oral hygiene status was fair to poor. Lips were incompetent at rest (Fig. 1). Treatment Objective was positive, the saddle angle was normal and mandibular retrognathism was due to the reduced corpus length. The patient had not attained menarche. The cervical vertebral maturation status showed the acceleration phase of growth CVMI 2 (Cervical Vertebrae Maturity Index) (Fig. 2). Treatment involved orthodontic fixed appliance mechanotherapy using metal brackets with 0.022 × 0.028 MBT prescription. Optimal orthodontic and esthetic result was achieved by nonextraction treatment protocol.
