Computer-based Simulation System for Dental Procedures

描述（由申请人提供）：近年来，临床牙科培训受到模拟技术快速发展的显著影响。计算机图形学的引入，加上力反馈（触觉）设备，有可能进一步改善广泛技能获得的临床培训。鉴于牙科修复手术是在复杂的3D空间中进行的有计划的干预，这些技术的应用将使学生和临床医生都能在虚拟的3D世界中练习技能。本计划的目的是进一步发展和评估一个基于计算机的牙科程序模拟系统。我们的第一阶段项目成功地证明了项目所有具体目标的技术可行性。这种新颖的系统集成了3D注册多模态成像数据（微ct和微磨削），为用户提供了3D空间中交互式的、立体的、3D计算机生成的成像数据重建，并允许与许多虚拟仪器进行数据集交互，同时使用独特的、先进的分布式处理系统以每秒1000次更新的速度生成实时触觉反馈。在该系统中开发的先进核心技术将被用于II期SBIR，以产生有用的，无废话的，临床验证的各种临床医生通常会遇到的牙齿准备的模拟。这样的系统对牙科学生的初步培训是有用的；为学生评价提供客观、定量的指标；对临床医师的持续培训、评估和再培训具有一定的指导意义。

DESCRIPTION (provided by applicant): In recent years training in clinical dentistry has been significantly impacted by the rapid growth of simulation technology. The introduction of computer graphics, together with force-feedback (haptic) devices, has the potential to further improve clinical training across a broad range of skills acquisition. Given that a restorative dental procedure is a planned intervention in a complex 3-D space, the application of these technologies would allow the student and clinician alike to practice skills acquisition in a virtual 3D world. The aim of this project is to further develop and evaluate a computer-based simulation system for dental procedures. Our Phase I project was successful in demonstrating technical feasibility of all specific aims of the project. This novel system integrated 3D registered multimodal imaging data (microCT and microgrinding), presented the user with an interactive, stereoscopic, 3D computer-generated reconstruction of the imaging data in a 3D space, and allowed for the interaction with that dataset with a number of virtual instruments while generating real-time haptic feedback at over 1000 updates per second using a unique, advanced distributed processing system. The advanced core technologies developed in this system would be leveraged for this Phase II SBIR to produce a useful, no-nonsense, clinically-validated simulation of the complete variety of tooth preparations that clinicians would typically encounter. Such a system would be useful for initial training of dental students; would provide for objective, quantitative metrics for student evaluation; and would be useful for continual training, evaluation and retraining of clinicians in practice.
