Clinical examination and diagnosis<\/span><\/h5>\n

[\/vc_column_text][\/vc_column][vc_column width=”3\/4″][vc_row_inner][vc_column_inner width=”1\/2″][vc_column_text css=””]CLINICAL EXAMINATION:<\/p>\n

A 13-year-old male patient presented with a deep bite, characterized by near-complete coverage of the mandibular incisors. Clinical evaluation revealed bi-arch crowding, dental rotations, and proclination of the maxillary lateral incisors, contributing to the patient\u2019s esthetic concerns. The facial profile was retrusive, consistent with mandibular retrognathism, and no significant periodontal abnormalities were detected.[\/vc_column_text][\/vc_column_inner][vc_column_inner width=”1\/2″][vc_column_text css=””]<\/p>\n

DIAGNOSIS:<\/p>\n

The patient presented with a skeletal Class II relationship with bilateral molar and canine Class II and a Class II division 2 dental pattern. The deep bite was associated with anteroinferior crowding and an accentuated Curve of Spee. Facial analysis revealed good symmetry, a slightly increased lower facial third, and a convex profile characterized by mandibular and chin retrusion. Lip competence was mildly reduced, with a decreased nasolabial angle and mentalis hyperactivity, all of which compromised overall facial harmony.[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][\/vc_column][\/vc_row][vc_row][vc_column width=”1\/4″][vc_column_text css=””]<\/p>\n
