Abstract

A 28-year-old male patient visited our clinic office with a chief complaint of incisor protrusion and open-bite. He was diagnosed with an asymmetrical anterior open‑bite, asymmetrical occlusion, unilateral crossbite, gummy smile, skeletal Class II pattern, loss of six molars, periodontal defect and restorative complication on the mandibular left first molar. He refused the surgical-orthodontic treatment option, although he wanted to correct the malocclusion. After periodontal treatment and initial alignment with Edgewise appliances .022”  .028” and the Tweed technique, differential intrusion of anterior and posterior teeth, left and right side in maxillary arch was necessary to maximize the skeletal treatment effects using two mini-implants as a temporary anchorage devices (TADs). These TADs were inserted at convenable areas on maxillary arch to allow reasonable biomechanics using archwires with accentuated curves of Spee. After a hopeful improvement of the malocclusion, extraction of the condemned mandibular left central incisor was done and the space was closed with a central loop to contract the mandibular arch, to shift dental midline and to mesialize the mandibular left dental sector achieving a compromised occlusion. These simple mechanics contributed to the effective intrusion of entire maxillary arch and differential intrusion of the anterior and posterior teeth, left and right side were achieved to treatment of the malocclusion with maximize skeletal treatment effects and a considerable improvement of the smile and profile, offering an alternative to orthognathic surgery for this patient.
