Cases of severely atrophic edentulous maxilla require reconstruction techniques employing bone grafts to promote adequate bone dimension for the successful placement of dental implants for prosthetic rehabilitation that reestablishes the patient's function and aesthetics. This study aims to present a severely atrophic edentulous maxilla reconstruction with the off-label use of recombinant human bone morphogenetic protein type 2 (rhBMP-2) associated with lyophilized particulate bovine bone xenograft for the prosthetic rehabilitation with osseointegrable dental implants. The paper describes a case of severely atrophic edentulous maxilla in a 42-year-old woman referred to the dental school with complaint of failure in adaptating to the dentures. The patient reported 27 years of maxilla edentulism and consecutive treatment failures, so the proposed therapy was the reconstruction of the maxilla with an association of rhBMP-2 and lyophilized bovine bone xenograft for increasing bone volume and further prosthetic rehabilitation with osseointegrated dental implants. The present report illustrates a case of atrophic edentulous maxilla in which the off-label use of rhBMP-2 was successful and the patient's prosthetic rehabilitation could be concluded. The 8 dental implants received prosthetic functional load during 1 year of follow-up with no complications. Based on the case presented, the association between rhBMP-2 and a bovine bone xenograft could be considered a viable option for the reconstruction of atrophic edentulous maxilla. After a year of functional prosthetic load follow-up, the patient is asymptomatic and satisfactorily adaptated to the prosthesis, which restored her functional and aesthetic demands.
