Column How it’s done – Functional mandibular propulsor and intra-maxillary and mandibular propellant supported on skeletal anchorage

Vol. 13 – Number 49 – 2020 Column How it’s done Page 17-23 Functional mandibular propulsor and intra-maxillary and mandibular propellant supported on skeletal anchorage João M. Baptista¹ Introduction This article aims to describe step by step the clinical use of a new approach to sagittal treatment of Class II and Class III malocclusions. We initially developed the Functional Mandibular Propulsor (FPM), capable of acting through practically constant forces. The Nickel-Titanium spring produces an optimum force for Class II correction in a physiological manner. We are now developing intramaxillary thrusters, using skeletal anchorage both in the maxilla and mandible. It should be noted that we do not know until now the existence of any propellant to be used in the maxilla with skeletal anchorage. Therefore, our work is the first to describe this possibility. ¹ Specialist in Orthodontics and Dentofacial Orthopedics – CFO, Visiting Professor at the Postgraduate Orthodontics School – UFPR.
