Unilateral scissors bite treated with a removable plate that incorporates a Ti-Ni wire

Orthodontics (Chic.). 2013;14(1):e222-6. doi: 10.11607/ortho.921.

Abstract

A plate that incorporates a Ti-Ni alloy wire can rapidly correct scissors bite. This article describes its use in the successful treatment of scissors bite. A female patient aged 7 years, 5 months with mixed dentition presented with a Class I molar relationship, Class I skeletal pattern, and average Frankfort-mandibular plane angle. The maxillary right central incisor was in a crossbite. A unilateral posterior scissors bite was also present on the left side. The plate was fitted and prescribed for nighttime wear. Positive overjet was achieved after 1 month of treatment. The posterior scissors bite was corrected after 3 months of treatment, and the midline shift was ameliorated. Because a Ti-Ni wire maintained a weak continuous force, the treatment period was minimized.
