Individual displaced teeth are generally treated orthodontically or prosthetically. But in cases of ankylosed teeth, the orthodontic approach, even when used with corticotomies, do not work at all. In cases of rotated teeth, it has a greater propensity for relapse. On the other hand, the prosthetic approach sacrifices the healthy tooth structure and may produce a somewhat compromised esthetic result. Single-tooth dento-osseous osteotomy is one of the orthognatic surgeries only for correction of individual tooth-bone segment alone. By attempting to use single-tooth dento-osseous osteotomies for ankylosed teeth and rotated teeth, we obtained satisfactory results. The advantages are: it is rapid and will move, a slight propensity for relapse and a good esthetic result. In order to successfully use this method, be especially careful to maintain the blood supply to the tooth-bone segment and when cutting Lbetween adjacent teeth so as not to injury to them.
