Abstract
- During orthodontic treatment of impacted teeth, use of appropriate anchorage against the traction force is important. Tooth anchorage with multi-bracket appliances is commonly used but sometimes it causes unwanted movements of adjacent teeth. Skeletal anchorage devices are therefore considered to minimize such side effects. Still their survival rate and positioning are highly limited according to the bone density and the interradicular space. This case report presents a case of two impacted teeth, one of which is dilacerated and horizontally angulated. Using the microplate with short screws and a bendable neck, negative effects on adjacent teeth were minimized and impacted teeth were repositioned with good stability.
