PURPOSE
This study measured maxillary sinus volume as an aid in determining graft bone volume before grafting of the maxillary sinus floor.
MATERIALS AND METHODS
Maxillary sinus size was measured in 32 cadavers (59 sinuses) using casts of the maxillary sinus made using dental impression material.
RESULTS
Anteroposterior length, height, width, and volume of the maxillary sinus (mean+/-SD) were 30.1+/-5.65 mm, 34.6+/-7.71 mm, 25.4+/-5.71 mm, and 11.3+/-4.60 cm3, respectively. When the sinus-lift procedure was simulated, inferior sinus volumes (mean +/- SD) were 3.51+/-1.23 cm3 for a 15-mm lift and 5.66+/-1.71 cm3 for a 20-mm lift.
CONCLUSIONS
In bone grafting of the maxillary sinus floor, taking into consideration individual differences in maxillary sinus volume and resorption of the grafted bone, 4.74 cm3 or more of the graft is required for a 15-mm lift, and 7.37 cm3 or more is required for a 20-mm lift.
目的
本研究测量上颌窦容积，以辅助确定上颌窦底植骨术前的植骨量。
材料与方法
使用牙科印模材料制作的上颌窦模型，对32具尸体（59个鼻窦）的上颌窦大小进行测量。
结果
上颌窦的前后径、高度、宽度和容积（均值±标准差）分别为30.1±5.65毫米、34.6±7.71毫米、25.4±5.71毫米和11.3±4.60立方厘米。当模拟鼻窦提升术时，15毫米提升高度时窦下容积（均值±标准差）为3.51±1.23立方厘米，20毫米提升高度时为5.66±1.71立方厘米。
结论
在上颌窦底植骨时，考虑到上颌窦容积的个体差异和植骨的吸收情况，15毫米提升高度需要4.74立方厘米或更多的植骨量，20毫米提升高度需要7.37立方厘米或更多的植骨量。
