ABSTRACT
Introduction: Skeletal class II is the most common dentofacial deformity in our country wich most of the times combines skeletal and dental components and depending on its severity, if it is not detected at an early age, it can require treatments that combine orthodontics and orthognatic surgery. The success of this type of treatment depends on multiple factors, of which the most important are: to obtain an adequate diagnosis and treatment plan in interdiscipline with Maxillofacial Surgery and the patient cooperation.
Material and methods: A 20-year-old female patient, with combined skeletal class II malocclusion and vertical maxillary excess, dolichofacial biotype, convex profile, bilateral molar class II, bilateral canine class II, increased
overjet and clinical absence of the teeth #14, #24 and #44, which were extracted in previous orthodontic treatments.
Objective: To improve the maxilo-mandibular relationship three-dimensionally, obtaining stability and occlusal function and providing an improvement in the facial aesthetics of the patient through an interdisciplinary treatment.
Results: We obtained an adequate maxillo-mandibular relationship, improvement in facial aesthetics, bilateral molar class I, bilateral canine class I, occlusal stability and periodontal health.
Conclusion: The case reported in this article fulfills the expected results in a patient with this type of dentofacial deformity, which was achieved through an interdisciplinary treatment, and through treatment alternatives that would allow us to work with what has been done in the previous orthodontic treatments.
