Open Bite Treatment in Adults

This case report presents an adult skeletal Class II hyperdivergent and dental Class I open bite case treated by using zygomatic miniplates as anchorage units. 17-year 7-month old female patient presented with a dental Class I molar relationship along with skeletally normal positioned maxilla (SNA:83°), retruded mandibula (SNB:74°) and increased vertical dimensions (GoGnSN:43°). Zygomatic miniplates were used for anchorage and fixed orthodontic appliances were used after extraction of four premolars. Molar intrusion, canine distalization and retraction of incisors were achieved by the help of zygomatic anchorage system. At the end of the treatment Class I canine and molar relationship was achieved, a good interdigitation was established, adequateoverjet and overbite were provided and crowding were resolved. While soft tissue profile was evaluated, it is seen that inadequate lip closure was eliminated and patient has favourable profile. In this case, patient gets access to a better esthetic, function and occlusion after the treatment with zygomatic miniplates.
