Reconstruction of atrophic maxilla with the use of allogenic bone graft and platelet concentrate – clinical case report

Resumo

The use of allogenic bone has the advantage of not producing donor area in the patient, which can decrease the morbidity. However, there is an important vascularization demand for this type of graft, which can be increased with the use of platelet concentrate. Objective: To report a case of atrophic maxilla reconstruction with particle allogenic bone associated with Platelet Rich Fibrin (PRF). Case report: A female patient, who presented a maxilla with a reduced alveolar ridge and pneumatization of the maxillary sinuses, underwent surgery to lift the maxillary sinuses and reconstruct the alveolar ridge, with macro and micro particulate allogenic bone associated with fluid/injectable PRF (i-PRF), and total covering of the graft with PRF membranes, for better accommodation and graft protection. The graft was osseointegrated and able to receive the implants. Conclusion: The technique was effective, presenting several advantages in relation to reconstruction with autologous bone, such as shorter surgical time, amount of material for the graft, and less surgical trauma.
