Conclusions
Within the limitations of this study and high attrition rate, the results revealed that the MAMP protocol can effectively increase the maxillary forward growth with sagittal control on the mandibular forward growth. The MAMP protocol provides good vertical control, which makes it one of the treatment choices in high-angle cases. Class III concave profile was improved due to the advancement of the upper lip and restraining of the soft tissue chin of the mandible.
