Bimaxillary Modification with Bone Anchored Protraction in Patients with Cleft Lip and Palate


Bone Anchored Maxillary Protraction (BAMP) has proven to be an effective alternative for treating moderate Class III malocclusion in growing individuals. This lecture will present the research outcomes from a fifteen-year experience at a single center regarding the use of BAMP in patients with cleft lip and palate, with a follow-up period of up to five years. The lecture will address several topics: What is the impact of BAMP on the zygoma-maxillary complex? How does BAMP treatment affect the soft tissue profile? Does BAMP treatment hinder the growth of the upper airway? Can BAMP treatment induce remodeling of the mandibular fossa? Can predictive factors for favorable results be identified? What are the typical problems and complications associated with BAMP treatment? This lecture aims to provide a comprehensive understanding of the indications and contraindications for BAMP treatment in patients with cleft lip and palate.
