摘　　要：目的根据咬肌及颞肌的解剖学特点,利用激光三维扫描结合解剖技术重建咬肌、颞肌三维数字化模型,探索肌肉等软组织建模及形态学研究的新方法。方法 1例颌面部形态正常的男性成年新鲜标本,解剖完全暴露咬肌、颞肌浅面,激光三维扫描系统对标本多次扫描;切成咬肌、颞肌后再次对标本进行多次扫描,形成轮廓点云文件;在Geomagic软件中处理,并进行观察测量。结果利用激光三维扫描的点云文件,在Geomagic软件中重建形成具有解剖特征的咬肌、颞肌3D数字化模型。结论通过激光3D扫描的点云文件重建的咬肌、颞肌数字化模型形态真实,并可进行形态学测量,为其形态学研究及生物力学分析提供了基础。Objective To explore a new method for establishing digital models of the masseter and temporal muscles and superficial soft tissue using three-dimensional laser scanning technique.Methods One adult male cadaveric head without malformation was dissected to expose the superficial portion of the masseterand temporalis.Multiple aspects of the sample were scanned with three-dimensional laserscanning system,and the point clouds of the masseterand temporal muscles were generated.The specimenwas scannedagainafterthe masseterandtemporal muscles had been removed.The digital model of the muscles was reconstructed with the point clouds using Geomagic software,and the morphology of the muscle model was observed and measured.Results The 3-D digital models of the masseter and temporal muscles with the anatomical characteristics were reconstructed based on the point clouds using Geomagic 8.0 software.Conclusion The digital model of the muscles can vividly demonstrate the muscle contours,whichprovides abasis formorphological study andbiomechanical analysis of the muscles.
