Background: Dentoalveolar ankyloses of the deciduous tooth may lead to collapse of the dental arch complicating eruption and development of the succedaneous permanent dentition. The early interceptive orthodontic treatment is recommended to avoid complications on the eruptive process of the successor tooth. Objective: The aim of this article is to report the orthodontic treatment of a patient with dentoalveolar ankylosis of the deciduous upper molar and impaction of the succeeding permanent teeth. Materials and methods: A 15 year-old female patient presented with a complaint about severely intruded maxillary left second deciduous molar and inclination of the adjacent tooth. Computed tomography scam (CT) showed that the premolars were found to be ankylosed and were extracted. The extraction spaces were closed by moving the posterior teeth mesially through NiTi closed springs with miniscrew anchorage. Results: In the maxillary arch, the first molars were positioned in the place of the second premolars. The occlusal posttreatment evaluation revealed a Class II molar and Class I canine relationship on the sides, normal overjet and overbite, and good intercuspation. Ideal functional occlusion was obtained. Panoramic radiography revealed good positioning and good periodontal health of the teeth, and the parallax of the roots of the teeth. The patient’s skeletal pattern was not altered by the mechanics and the facial esthetics was not compromised. Conclusion: It is important to diagnose the dental ankyloses or impaction problems as early as possible in order to treatment planning achieve better results with a great long-term stability.
