Vinholi GH, Brum IS, Devita RL, Amorim JCL, de Carvalho MAA, de Carvalho JJ. Utilization of nano-hydroxyapatite mixed with platelet rich fibrin for reconstruction of severe atrophied over pneumatized maxilla: A case report. Edorium J Dent 2021;8:100042D01GV2021.ABSTRACT
Introduction: With the current need for large bone reconstructions due to very robust losses in skeletal architecture, not only of the maxillary and mandibular regions but also in other regions of the body, this guided bone regeneration has been increasingly used.
Case Report: A leukoderma patient at 52 years of age sought the implantology clinic of the Brazilian Dental Association (ABO) to solve his case of tooth loss. The patient presented overly aggressive bone loss in the total maxilla, and, because of this, it was planned to reconstruct the lost area with a synthetic particulate nano-biomaterial (Blue Bone, Curitiba, Brazil), with the help of the platelet aggregate (PRF). For the surgery, 6 grams of this biomaterial were used, in the anterior region of the maxilla, tent screws were placed to stabilize the grafted bilateral and maxillary sinus lifting surgeries were performed in the posterior regions. The entire regenerated area was covered with L-PRF membrane for better stability and healing. An incredibly significant gain in bone volume was observed six months after surgery throughout the regenerated region, enabling the placement of dental implants (Systhex, Curitiba, Brazil) and later the placement of the supported prosthesis.
Conclusion: The nano graft presented a very favorable result in the gain of bone volume, proving to be an excellent indication for more severe cases of bone loss.
