The maxillary sinus is the largest among paranasal sinuses, lined with Schneiderian membrane having an innate osteogenic potential. The alveolar ridge resorption and pneumatization of the maxillary sinus are inescapable findings postextraction, which may diminish the vertical bone dimensions needed for endosteal implant placement. To overcome these problems, maxillary sinus augmentation using bone grafting materials has been advocated but the cost of graft materials, chances of graft contamination, graft allergy, etc., are the disadvantages/risks associated with it. In order to accomplish passable density of stable peri-implant bone, which aids in increasing implant primary stability; Densah bur-assisted osseodensification approach is highly recommended. To improve Schneiderian membrane, osteogenic potential and bone volume platelet-rich fibrin (PRF) are advocated. The present case described the successful outcome of single-stage graftless immediate implant placement in the edentulous maxillary first and second molar region with ≤3-4 mm of vertical alveolar bone height utilizing lateral window and implant with PRF plug as well as PRF membrane-assisted tenting approach at 1-year follow up.
上颌窦是鼻窦中最大的，内衬具有先天成骨潜能的施奈德膜。拔牙后牙槽嵴吸收和上颌窦气化是不可避免的现象，这可能会减少骨内种植体植入所需的垂直骨尺寸。为克服这些问题，有人主张使用骨移植材料进行上颌窦提升，但移植材料的成本、移植污染的可能性、移植过敏等都是与之相关的缺点/风险。为了实现有助于提高种植体初期稳定性的稳定种植体周围骨的可接受密度，强烈推荐使用Densah钻辅助骨致密化方法。为改善施奈德膜，有人主张使用富含血小板纤维蛋白（PRF）来提高成骨潜能和骨量。本病例描述了在垂直牙槽骨高度≤3 - 4毫米的无牙上颌第一和第二磨牙区域，采用侧窗技术、植入带有PRF塞以及PRF膜辅助帐篷技术的种植体，单阶段无移植即刻种植在1年随访时的成功结果。
