数字化标准牙冠在牙体解剖教学中的应用

Application of digitized standard teeth crown in dental anatomy instruction

目的建立标准牙冠三维可操作平台,为牙体解剖学教学提供多媒体手段。方法利用三维激光扫描仪获取28颗标准恒牙的表面数据,在Matlab 5.3软件平台上编写软件,对标准牙冠进行三维重建,并对数据进行一定的处理,使其满足教学的需要。结果获取了28颗标准恒牙的表面数据,建立了标准牙冠的操作平台,对其进行了三维重建,在牙冠上定义了特征区,并实现了剖面的功能。结论数字化标准牙冠模型可以成为牙体解剖教学的有力计算机辅助手段。

Objective To establish a software platform of standard teeth crowns and provide a multimedia method for dental anatomy instruction. Methods 28 standard teeth crowns were scanned using a 3-D laser scanner, software was written on the basis of Matlab 5.3, the 3-D models of the crowns were reconstructed and the acquired data were processed to fulfil the requirements of dental anatomy instruction. Results The 28 crowns data were obtained, on the platform of software the crowns models were reconstructed, the characterized regions were defined on the surfaces of digitized crowns and the section plane could also be viewed. Conclusion The digitized models of standard teeth crowns could provide a new computer aided method for dental anatomy instruction.
