Atrophic maxilla rehabilitation is a complex treatment procedure and the treatment involves bone reconstruction with bone grafts, dental implants placement and restorative phase to require function and esthetics to the patient. The aim of this case report was demonstrate the effectiveness of the combination of bone reconstruction techniques with a tent-pole grafting and sinus floor elevation as treatment of an atrophic maxilla, both techniques were performed with Leukocytes Platelet-Rich Fibrin (LPRF) and implant placement association. A 51-year-old female patient with chief complains associated with removable dental prosthesis in maxilla and the planning were based in bone reconstruction for anterior and posterior maxilla. For anterior maxilla, screws of titanium were positioned following the tent-pole technique and for posterior maxilla were performed sinus augmentation bilaterally, both techniques for bone reconstruction were associated with a xenograft (BioOss®, Geitslich, Switzerland) in conjunction with L-PRF membranes and six dental implants were installed. After 6 months, the second-stage was performed to change the abutment for prosthesis confection, and L-RPF was over again inserted in the surgical area to increase the soft tissue. After 90 days the patient received the final restoration made with ceramic and coated with zirconium (e-Max ceram). The patient showed thorough of 9 months of follow-up since baseline, good overcomes in implant stability, and bone augmentation demonstrated that reconstruction techniques performed in this case can be an alternative to patient with atrophic maxilla when associated with L-PRF.
