Mia-assisted orthodontic treatment for dental malocclusion secondary to periodontal disease.

In contemporary dental care, an increasing number of adult patients with periodontal disease are seeking orthodontic treatment. Achieving optimal results in such adult patients is difficult because decreased posterior tooth anchorage is risky. This case report demonstrates the use of miniscrew implant anchorage (MIA) in a Chinese male 21 years 5 months of age with maxillary and mandibular anterior dental spacing, bimaxillary protrusion, and severe bone loss caused by periodontal disease. Prior to orthodontic treatment, the patient underwent treatment to control his periodontitis. The patient was treated with 0.022-in straight-wire orthodontic appliances. After 17 months of active orthodontic treatment, the patient had healthier periodontal tissue with increased bone support, as well as improved facial esthetics and a functional occlusion. The results demonstrate that MIA is useful in enhancing anchorage in patients with bone loss associated with severe periodontal disease.
