Uncontrolled orthodontic movements and compensation to avoid orthognatic surgery can cause unwanted bone resorption, which can cause future problems. Bone morphogenetic protein Rh-BMP2 (BMP®) has been shown to be effective in inducing bone regeneration, obtaining observable and favorable results in a short period of 8 to 10 weeks. The objective was describing a case of guided bone regeneration using BMP® to counteract bone resorption of the lingual mandibular bone of lower anterior teeth resulting from orthodontics. Female the 36- year-old patient with long-standing orthodontic treatment. Radiographically, lingual mandibular bone resorption is seen. Bone reconstruction and orthodontic treatment was planned to preserve affected teeth. A full thickness intracrevicular approach was from lower left first premolar to lower right second premolar. Liquid BMP® was used and mixed with BCP and particulate bone, covered with collagen membrane, finally activated oxygen with lactoferrin was applied. Subsequently, BMP® was infiltrated into the surgical site 21 days after the surgical procedure. Clinical control was performed at 7, 14, 21 days and tomographic control at one month and 6 months. Bone regeneration was evident to begin orthodontic treatment to reestablish the correct position of the lower anterior teeth. We can conclude that the multidisciplinary management and the use of bone growth factors can improve the prognosis of severe cases of resorption resulting from uncontrolled orthodontic movements.
