Abstract

Autogenous tooth transplantation is one of the options used in combination with an orthodontic treatment in cases of missing, embedded or impacted tooth. Those who undergo tooth transplantation should be physically evaluated to rule out contraindications, if any, for surgery. The donor tooth should possess three-quarter root formation without abnormal root morphology while the bony wall at recipient site should be at least 0.5 mm. Tooth transplantation can be performed in several areas, i.e. incisor, canine, premolar and molar. Its success rate is 50-97 percent. After transplantation, the tooth must be fixed for periodontal healing with wire, acrylic splint, acidetch composite resin splint, orthodontic appliance or suture material. Surgical complications to be observed are infection, pulp necrosis, internal and external root resorption. Within 6 months after transplantation, evaluation of pulpal healing by the presence of pulp canal obliteration gives more certain result than by electric pulp testing. However, the optimal time for tooth movement should be after periodontal healing and before total pulp canal obliteration, which is 3-9 months after transplantation. Pulp necrosis has been reported to increase in a multi-rooted tooth following a rotation movement. Therefore, such type of tooth movement should be taken care of.
