title: Uprighting mesially impacted mandibular molars with 2 miniscrews.
abstract: Mesially tilted or impacted mandibular molars cause occlusal disharmony and periodontal problems. For proper restoration of the occlusion and to prevent further periodontal damage, uprighting of tilted molars is the recommended treatment option. Although several orthodontic methods including miniscrews have been proposed, most of them have innate limitations and problems such as the possibility of unwanted tooth movement. In this case series, we introduce a new system that uses 2 miniscrews with slots that can accommodate rectangular orthodontic wires to 3 dimensionally control the tilted molar in 3 patients. We also discuss the advantages and possible disadvantages of this new system.
