目的研究髂嵴附近的解剖学特点及骨量参数,探讨其应用于下颌骨体部重建并行种植牙修复的适应性.方法选取16具防腐保存完好的人体骨盆标本.根据预设的位点,测量髂骨移植区骨块的长、宽、高及骨皮质厚度.结果髂骨移植区骨块长度(77.2±6.1) mm,高度[(38.2±4.2)～(41.9±4.7)] mm;宽度自髂嵴至基线逐渐减小,距髂嵴10 mm以内最小宽度为(8.4±2.2) mm,距髂嵴15 mm以内最小宽度为(6.5±2.1) mm；骨皮质截面最大厚度位于髂嵴顶部,为(2.9±1.3)mm～(3.4±0.8)mm.结论髂骨解剖特征适宜下颌骨体部重建并种植牙及恢复咬合功能.

Objective To investigate the anatomical features of iliac bone grafts used for mandibular reconstruction and dental implantation.Methods Sixteen cadavers were dissected.The length,width,height and cortical thickness of the iliac bone were measured with respect to points determined by the relative dimensions of the bone.Results The length of iliac bone graft was (77.2 ± 6.1) mm.The height was from(38.2 ±4.2) mm to (41.9 ±4.7) mm.The width decreased from iliac crest to base line.The least width 10 mm and 15 mm away from iliac crest were (8.4 ±2.2) mm and(6.5 ±2.1) mm respectively.The greatest mean cross-sectional cortical thickness at the intermediate line of the iliac crest was (3.4 ± 0.8) mm.Conclusions Anatomical features of iliac bone are suitable for designing bone grafts for mandibular reconstruction followed by dental implantation.
