Orthodontic Treatment after Extraction of Ankylosed Second Primary Molars: A Case Report

Abstract
Ankylosed teeth are defined as the fusion of the cementum or dentin of the root surface with the surrounding alveolar bone. The etiology of ankylosis is divided into extrinsic and intrinsic factors. Extrinsic factors are local mechanical trauma, localized infection, chemical or thermal irritation. Intrinsic factors include a genetic or congenital gap in the periodontal ligament. Tooth ankylosis is important to orthodontists because the malocclusions associated with it become progressively worsen and the ankylosed tooth could not move by orthodontic force. This case report refers to an 18-year-old female who had orthodontic treatment with extraction of ankylosed lower primary second molars (75, 85) and upper left first premolar (24), following by protraction of lower first molars (36, 46) to close the ankylosed extraction space. After orthodontic treatment, the patient was satisfied with better chewing pattern and had Class I canine and molar relationship on both sides. The treatment time was approximately 2 years, and the patient was advised to wear upper and lower wraparound retainers full-time for 2 years followed by night time after the 2-year period. The reason for extraction 75, 85 was the severe root resorption that rendered corticotomy cannot be performed or proximal and occlusal not built up properly. Therefore, the treatment applied to this case was orthodontic space closure with a substitute, but the post-treatment radiographic finding shows some loss of marginal bone at the mesial of 36, 46 because of the surgical process in removing ankylosed 75, 85, which some bone had to be taken out
