Objective:
This case report describes the orthodontic treatment and follow-up of a patient with Angle Class III malocclusion.
Cases:
This article described a 37-year-old male with anterior crossbite. Clinical examination showed a straight facial profile and average mandibular plane angle. The treatment include extraction of third molars. Orthodontic miniscrews were inserted at bilateral lower buccal shelf for anchorage. We bonded lower posterior teeth and skipped anterior teeth to avoid round tripping in the distalization phase. Bilateral sliding jigs and inter-arch elastics were then used for lower dentition distalization. When space created, mandibular anterior teeth were en-masse retracted. After 20 months, canine and molar Class I relationship with normal overbite and overjet were established. Facial profile was improved. One year post-treatment follow up shows stable result.
Discussion and Summary:
In treating dental Class III adult patient without skeletal discrepancy, orthodontic camouflage treatment is the choice. Usually bicuspids were extracted to relieve crowding and achieve better overjet. Lower dentition distalization is another treatment alternative. This case demonstrates that by using orthodontic miniscrews as anchorage for lower dentition distalization is a viable option when treating Angle Class III malocclusion with anterior cross-bite.
