Elevation of the sinus floor allows the correct number and length of oral implants to be placed. The sinus membrane is dissected blindly, usually by a crestal approach, but several internal configurations of the maxillary sinus or intrasinus septa can cause problems. We studied 150 sinuses from 40 male cadavers, and 35 randomised male patients by anatomical dissection and computed tomography. Forty-six subjects (61%) had no bony septa or had septa less than 4mm. Twenty-nine (39%) had bony septa of which seven were incomplete, one had a complete bony septum in each maxillary sinus, and 20 had symmetrical bony septa. We present the results of a study of bony intramaxillary sinus septa and the potential problems they can cause during elevation of the sinus floor.
上颌窦底提升可使口腔种植体植入的数量和长度正确。通常通过嵴顶入路盲目剥离窦膜,但上颌窦的几种内部结构或窦内间隔可能会引发问题。我们通过解剖和计算机断层扫描研究了40具男性尸体的150个鼻窦以及35名随机选取的男性患者。46名受试者(61%)没有骨间隔或骨间隔小于4毫米。29名(39%)有骨间隔,其中7个不完整,1名在每个上颌窦中有一个完整的骨间隔,20名有对称的骨间隔。我们展示了一项关于上颌窦内骨间隔及其在窦底提升过程中可能引发的潜在问题的研究结果。
