Introduction: The difficulties in correcting the bone discrepancies of class iii malocclusions due to the complexity of existing treatments, the unpredictability of bone growth, the development and treatment outcomes for young patients, and the evident physical characteristics of the subjects who suffer from them make them a challenge when considering successful treatment plans for correction.   Case: A 10-year-old male patient attended the maxillary orthopedics clinic of the graduate program Pediatric Dentistry and Maxillary Orthopedics of the School of Dentistry at the Universidad del Valle (Cali-Colombia) for re-evaluation. He does not report family history of skeletal or dental anomalies; a prominent chin is clinically observed.   Aim: To assess the effect of a treatment with hybrid hyrax, protraction mask and mini-implants in a patient for the correction of class iii malocclusion.   Results and conclusions: The combination of hybrid hyrax, face mask and Alt-ramec protocol responds to a real skeletal change due to the direct transmission of forces to the bone, thus abolishing the den- toalveolar camouflages that produce satisfactory results at the dental, facial and even psychological levels in patients with class iii skeletal malocclusion.
