Implantation in the posterior maxilla is more challenging due to the insufficient bone height after maxillary sinus pneumatization and the low bone density. Osseodensification (OD) is considered a novel, less invasive, and more effective indirect sinus floor elevation technique.
A 52-year-old male presented to the oral and maxillofacial surgery department with a main complaint of chewing difficulties in the right posterior area maxilla (teeth numbers: 26 and 27). A cone-beam computed tomography (CBCT) imaging showed that the residual bone height ranged between 1 and 4 mm and the width ranged between 9 and 12 mm in the area of teeth numbers 16 and 17.
The treatment plan was to extract the teeth (numbers: 16 and 17) and conduct internal sinus lifting and bone grafting using the OD burs with immediate implantation.
OD is proposed as an alternative procedure to the direct (lateral window) sinus floor elevation procedure. The amount of vertical bone gain obtained by this technique in transcrestal sinus lifting can be the same as external sinus lifting in this case.
OD can be considered a promising technique for direct sinus floor elevation, considering the amount of vertical bone gain obtained by this technique.
由于上颌窦气化后骨高度不足以及骨密度低，在上颌后牙区植入种植体更具挑战性。骨致密化（OD）被认为是一种新颖、侵入性较小且更有效的间接上颌窦底提升技术。
一名52岁男性因右上颌后牙区（牙齿编号：26和27）咀嚼困难为主诉就诊于口腔颌面外科。锥形束计算机断层扫描（CBCT）影像显示，16和17号牙区域剩余骨高度在1至4毫米之间，宽度在9至12毫米之间。
治疗方案是拔除牙齿（编号：16和17），使用OD车针进行上颌窦内提升及骨移植并即刻植入种植体。
OD被提议作为直接（外侧开窗）上颌窦底提升术的替代方法。在此病例中，该技术在经牙槽嵴上颌窦提升术中获得的垂直骨增量与上颌窦外提升相同。
考虑到该技术获得的垂直骨增量，OD可被视为一种有前景的直接上颌窦底提升技术。
