ALFONSO VALDES, Hermes et al. The retropropulsor and Buño stimulator: use in mandibular prognathism, cephalometric changes. Rev Ciencias Médicas [online]. 2014, vol.18, n.3, pp.473-480. ISSN 1561-3194.

Introduction: a prospective study was conducted with the use of the retropropulsor and stimulator of Professor Indalecio Buño in 24 patients with mandibular prognathism in mixed dentition. Objective: to know the cephalometric changes during the use of the retropupulsor and stimulator. Material and methods: patients underwent lateral radiographs before and twelve months after, comparing cephalometric changes obtained as a result of skeletal and dentoalveolar changes achieved, taking into account sex too. Results: statistically increase of SNA angle and very significant reduction in SNB angle were found, which represented a significant change of the ANB angle. Conclusions: regarding sex, there were significant changes in the SNA angle in males and in females in SNB angle, in addition to a significant variation in females of 1 SNB angle. These changes helped in improving the profile, concave, and to uncross previous bites that characterize patients with class III mandibular prognathism syndrome.
