Three-dimensional reconstruction of embryological structures from histological serial sections is necessary when researching questions concerning formal development and mutual influences due to neighboring relationships. Graphical reconstructions can be performed by personal computers. In the present paper the need for 3D-reconstructions is explained, and examples showing the development of human dental primordia and their surrounding structures of specimens ranging between 18 and 64 mm CRL are presented. The contour-line plots that are provided by the software HISTOL are graphically reworked to anatomical drawings. Spatial impediment as one of the factors responsible for development of tooth form is discussed on the basis of the 3D-reconstructions.
在研究有关形态发育以及相邻关系所产生的相互影响等问题时，从组织学连续切片对胚胎结构进行三维重建是很有必要的。图形重建可通过个人计算机来完成。在本文中，解释了三维重建的必要性，并展示了人类牙原基及其周围结构在头臀长18至64毫米标本中的发育情况。由HISTOL软件提供的轮廓线图被加工成解剖学绘图。基于三维重建讨论了空间阻碍作为牙齿形态发育的影响因素之一。
