Corrección de una clase III esqueletal con anclaje óseo en paciente en crecimiento: Reporte de caso

Background: Skeletal class III is a dentofacial deformity where the lower third of  face is more prominent. The treatment is decided according to the etiology and age of the patient; If the patient is in growing, the malformation can be treated with an interceptive protocol and if possible, avoid a orthognathic surgery in the future. Objective: Improve the skeletal class, uncross the bite or obtain an edge-to-edge bite, improve the position of the upper lip and evaluate the initial-final relationship of ANS and ANB. Case report: 13-year-old male patient, with no reported pathological or family history; presents skeletal class III, vertical growth, molar class I and canine III; he was treated with the protocol of mini BAMP (bone anchored maxillary protraction) plates, intermaxillary elastics and a palate with flat tracks. Results: The orthopedic phase lasted five months and an edge-to-edge bite and skeletal class I were achieved. Discussion: Results were obtained with the use of mini implants without extraoral anchorage in less time compared to other methods that have to be used for 9-12 months. Conclusion: The BAMP protocol can be used in growing patients without a face mask to correct skeletal class III.
