建立口腔修复学教学及临床三维多媒体软件的初探

The prosthodontical three-dimensional multimedia system developed for dental education and chairside communication

目的为提高口腔医学院学生的学习效率和临床医患交流的质量,初步探讨建立辅助口腔医学教学和临床医患交流的三维多媒体软件的方法。方法在 Windows 系统下收集、建立一套正常牙颌组织以及口腔修复学相关实体的三维模型,赋予模型材质,制作三维虚拟场景,渲染生成三维图形和三维动画,最后编写三维多媒体浏览器,将三维虚拟场景、三维图形和三维动画、以及归纳整理的文字内容全部按照口腔修复学教材中的章节形式整合到三维多媒体浏览器中,完成整个口腔修复学教学及临床三维多媒体软件的建立。结果成功研发了一种可用于口腔修复学教学的三维多媒体软件,该软件包含文字、三维图形、三维动画和三维虚拟场景等形式的多媒体,内容涵盖普通高等学校口腔修复学教材的基本内容,该软件可用于辅助口腔修复学课堂和实验室教学以及临床医患交流。结论该软件的成功开发说明了建立辅助口腔修复学教学和临床三维多媒体软件在技术上是可行的,同时预示口腔医学其他学科开发类似软件的可行性和可能性。

Objective To develop a three-dimensional multimedia system for enhancing the efficiency of dental education and chairside communication. Methods A set of three-dimensional digital models of normal teeth and jaws related to dental education in prosthodontics were acquired or established under Microsoft Windows. The three-dimensional models were reedited and rendered with texture attached, producing a large number of three-dimensional pictures and short animated pictures. A software platform was established for displaying all sorts of media, including the three-dimensional models. Finally, all media files produced or gathered before were integrated into the platform, similar to the textbook in chapter adopted in dental education at university. Results The prosthodontical three-dimensional multimedia system was successfully developed. The system covered basic information within the current textbook of prosthodontics, three-dimensional pictures, animated pictures, and virtual three-dimensional scenes. The system might serve as an assistant tool in dental education and chairside communication. Conclusions It is technically feasible to establish the prosthodontical three-dimensional multimedia system, according to experiences in this study. The success also anticipates the possibility and feasibility of developing similar systems in other disciplines of dentistry.
