Interdisciplinary treatment in an adult patient with skeletal class III malocclusion and retained upper canines: case report

Résumé

Introduction: Class III malocclusion is considered the most severe within the classification of malocclusions. In most patients, the etiology may be divided in skeletal and dentoalveolar components. In the adult patient, because skeletal growth has ceased, treatment options are reduced to two possibilities: camoufl age or orthognathic surgery. These complex cases require careful planning, a multidisciplinary approach and patient cooperation. Material and methods: A 44-year-old female with skeletal class III malocclusion, brachyfacial biotype, concave profi le, bilateral molar class III, nonassessable canine class due to the presence of temporary canines; an edge-to-edge incisor relationship and anterior crossbite of the temporary canines. Objective: To improve the maxillo-mandibular relationship obtaining good occlusal function as well as to improve the aesthetics of the patient through a multidisciplinary treatment. Results: Maxillo-mandibular relationship was improved, canine guidance was achieved with implants and prosthesis, a bilateral class I molar relationship was obtained as well as good occlusal function. Periodontal health was maintained. Conclusion: The multidisciplinary approach was successful in achieving the desired therapeutic results of improved function, improved aesthetics and improved self-esteem in this patient.
