Recombinant human bone morphogenetic protein 2 (rhBMP-2) is an alternative bone substitute for extensive maxillary bone defects which avoids the disadvantages associated with other grafting materials. This report details a case of a 32-year-old female with a severe vertical and horizontal maxillary bony defect that developed after tumor removal. She underwent two unsuccessful regenerative surgeries with an iliac bone graft. Reconstruction of the maxillary defect was planned by offlabel use of rhBMP-2/absorbable collagen sponge (ACS) combined with a bone marrow aspirate concentrate (BMAC) and allograft in a titanium mesh covered in platelet-rich fibrin (PRF). Clinical and radiographic evaluations showed good quality and quantity of bone formation, and she was rehabilitated with dental implants and prosthodontic treatment. Based on this case, the use of rhBMP-2 as a graft material appears encouraging with a satisfying outcome. The present case is aimed at reporting the clinical and radiographic effectiveness of rhBMP-2/ACS in combination with PRF and a titanium mesh for severe maxillary bone defects. Future investigations will be required to ascertain the long-term survival of implants in areas grafted with rhBMP-2.
重组人骨形态发生蛋白2(rhBMP-2)是一种用于大面积上颌骨缺损的替代骨替代物,可避免与其他移植材料相关的缺点。本报告详细介绍了一例32岁女性患者,该患者在肿瘤切除后出现严重的上颌骨垂直和水平骨缺损。她接受了两次使用髂骨移植的再生手术,但均未成功。计划通过非标签使用rhBMP-2/可吸收胶原海绵(ACS)联合骨髓抽吸浓缩物(BMAC)和同种异体骨,并将其置于富含血小板纤维蛋白(PRF)覆盖的钛网中来重建上颌骨缺损。临床和影像学评估显示骨形成的质量和数量良好,患者通过牙种植体和修复治疗得以康复。基于此病例,使用rhBMP-2作为移植材料似乎前景乐观,结果令人满意。本病例旨在报告rhBMP-2/ACS联合PRF和钛网治疗严重上颌骨缺损的临床和影像学效果。未来需要进行研究以确定在使用rhBMP-2移植的区域中种植体的长期存活率。
