Abstract
Abstract Background The present case report describes the orthodontic treatment and long-term follow-up of an adult female patient (27 years) who was diagnosed with a mild Class III malocclusion characterised by an anterior and lateral open bite and three periodontally-compromised first permanent molars. Aim The aim of treatment was to provide an acceptable aesthetic and functional occlusion while, at the same time, improving the periodontal prognosis. Methods The patient was treated with fixed orthodontic appliances utilising direct and indirect skeletal anchorage derived from two mini-screws placed in the palate and one mandibular buccal mini-screw. Results The objectives of good aesthetics, a functional occlusion, a healthy periodontium and a balanced profile were achieved. The total treatment time was 31 months, which comprised 13 months of maxillary fixed labial appliances and 25 months of mandibular fixed labial appliances. The three-year follow-up records showed stability of the Class III correction.
Highlights
The tooth most commonly lost to dental caries or periodontal disease is the first permanent molar.[1]
Treatment is more complicated if the patient has an anterior open bite and requires maxillary posterior intrusion
Titanium mini-implants have become popular for providing absolute anchorage during tooth movement as they are simpler, cheaper and more convenient than endosseous implants that have previously been used.[2,4,6,7,8,9,10]
Summary
The tooth most commonly lost to dental caries or periodontal disease is the first permanent molar.[1]. Treatment is more complicated if the patient has an anterior open bite and requires maxillary posterior intrusion. Titanium mini-implants have become popular for providing absolute anchorage during tooth movement as they are simpler, cheaper and more convenient than endosseous implants that have previously been used.[2,4,6,7,8,9,10] The mini-implants have pushed the envelope for tooth movement with the potential benefit of avoiding bimaxillary surgery in selected cases.[11] The commonly reported site for mini-implant insertion is the buccal dento-alveolar region, which may place the miniscrew in the path of moving teeth. The present case report describes the orthodontic treatment and long-term follow-up of an adult female patient (27 years) who was diagnosed with a mild Class III malocclusion characterised by an anterior and lateral open bite and three periodontally-compromised first permanent molars. Aim: The aim of treatment was to provide an acceptable aesthetic and functional occlusion while, at the same time, improving the periodontal prognosis. The three-year follow-up records showed stability of the Class III correction. (Aust Orthod J 2015; 31: 87–97)
