ABSTRACT

Generalized external root resorption represents a problem when performing orthodontic treatment, it requires making decisions that should always be based on the diagnosis carried out by an interdisciplinary team. Objective: To describe the treatment of a patient with generalized radicular resorption with a complete diagnostic process that must be followed in order to preserve the tooth structure and the connective insertion. Case report: 14-year-old female patient, with reason for consultation: «I have a tooth out of place»’, with a dolichofacial biotype, class II skeletal malocclusion, class I molar, class I dog, negative osseous discrepancy, convex profile, lip incompetence, superior lateral incisor crossed, generalized radicular resorption, which predominates in upper anterior incisors. The treatment was orthodontics (with Roth slot 22 fixed appliances), extractions of upper and lower second premolars, accelerated space closure and occlusal adjustment. Result: At the end of the treatment, aesthetics, preservation of the insertion and dental structure and a functional occlusion were achieved. Conclusions: Patients with generalized root resorption need to be diagnosed correctly, it is important to know that the results are limited to use light and controlled forces and it is very useful to take advantage of the phenomenon of regional acceleration that is given by the dental extractions, closing the spaces from initial stages of treatment.
