Introduction: After the loss of the dental element, the process of bone loss and adaptation of the soft tissues begins, allowing a remodeling of the edentulous area, creating defects in height and width of the residual bone, which may lead to pneumatization of the maxillary sinus, impairment the aesthetics, function and oral health of the patient. The quality and quantity of tissue and bone graft and conjunctive membrane are considered to be fundamental to the successful implantation of the implant. The technique of maxillary sinus lift and the installation of osseointegrated implants has made it possible to recover the aesthetics and function for the patient. Case report: Patient R.L.M.S., 43, female, leucoderma, sought care in a private clinic reporting dissatisfaction with the absence of dental elements and the aesthetics of her smile and desire to perform dental implants. At the clinical examination, it was observed low in the cortical bone at the height of the element 15 due to the loss of it and accommodation of the soft tissues on the region. Radiographically and tomographically, bone remnants are observed at reduced height and width, in addition to pneumatization of the maxillary sinus in the region of 15. Final considerations: It is corroborated that the technique of maxillary sinus lift, assisted with bone graft and heterogenous membrane for immediate installation of the osseointegrated implant in the posterior region of the right maxilla, it is configured as an optimal reconstructive technique, since it does not allow the accomplishment of two surgical steps for the patient, lower costs, and reduced treatment time.
