初步选定的测量项目有四部分136项，颅颌面硬组织立体形态图具有能多方向观察、光滑、透视感强等特点。
Four parts items consisting of 136 items are selected first and 3-D perspective curving illustrations may be rotated for viewing in all directions.
目的：将种植体植入相应部位的组织内，以提高对颅颌面赝复体的支持和固位作用。
Objective: To improve the supporting and stabilizing function of craniofacial-maxillofacial prostheses by implants implanted in the corresponding positions.
结论：该模型可用于颅颌面硬组织在正中矢状面上的形态特征及因生长、正畸矫治、正颌手术引起的形态变化研究。
Conclusions:This model may be applied for the study of morphologic characteristics and changes induced by growth, orthodontic treatment and orthognathic operation on middle sagittal plane.
