Abstract

Tooth extraction simulation with force feedback can provide a valuable training tool for dental students, familiarizing them with the detailed motion and force patterns involved in this procedure. This simulation encounters two major challenges - replicating the forceps' 7-DoF motion and accurately simulating the distinct phases of tooth extraction. This paper presents a comprehensive haptic simulation framework for simulating tooth extraction with force feedback, combining both hardware and software solutions. A pivotal feature of this system is the 7-DoF haptic rendering algorithm capable of simulating the 7-DoF motion of forceps. Additionally, a haptic handle resembling the extraction forceps and offering robust connectivity is developed. Furthermore, a multi-phase tooth extraction framework is proposed to simulate the entire tooth extraction process. This framework incorporates physical models to emulate the haptic characteristics of different extraction phases and includes predefined entry criteria for each phase to achieve accurate identification and seamless transitions. The system's effectiveness is validated through objective and subjective experiments, confirming its ability to faithfully replicate the unique haptic features of each extraction phase. Feedback from dental novices and experts indicates that this system could make a significant contribution to tooth extraction training, providing distinct advantages over traditional oral model practices.

多阶段拔牙过程的触觉渲染。

带力反馈的拔牙模拟可以为牙科学生提供有价值的训练工具，使他们熟悉拔牙过程中涉及的详细运动和力模式。这个模拟遇到了两个主要的挑战——复制镊子的7自由度运动和准确地模拟拔牙的不同阶段。本文提出了一种综合的基于力反馈的拔牙触觉仿真框架，结合硬件和软件解决方案。该系统的一个关键特征是能够模拟钳子7自由度运动的7自由度触觉渲染算法。此外，还开发了一种类似于拔牙钳的触觉手柄，并提供强大的连接。此外，提出了一种多阶段拔牙框架来模拟整个拔牙过程。该框架结合了物理模型来模拟不同提取阶段的触觉特征，并包括预定义的每个阶段的进入标准，以实现准确的识别和无缝过渡。通过客观和主观实验验证了该系统的有效性，证实了其能够忠实地复制每个提取阶段的独特触觉特征。来自牙科新手和专家的反馈表明，该系统可以为拔牙训练做出重大贡献，提供比传统口腔模型实践明显的优势。

期刊介绍： IEEE Transactions on Haptics (ToH) is a scholarly archival journal that addresses the science, technology, and applications associated with information acquisition and object manipulation through touch. Haptic interactions relevant to this journal include all aspects of manual exploration and manipulation of objects by humans, machines and interactions between the two, performed in real, virtual, teleoperated or networked environments. Research areas of relevance to this publication include, but are not limited to, the following topics: Human haptic and multi-sensory perception and action, Aspects of motor control that explicitly pertain to human haptics, Haptic interactions via passive or active tools and machines, Devices that sense, enable, or create haptic interactions locally or at a distance, Haptic rendering and its association with graphic and auditory rendering in virtual reality, Algorithms, controls, and dynamics of haptic devices, users, and interactions between the two, Human-machine performance and safety with haptic feedback, Haptics in the context of human-computer interactions, Systems and networks using haptic devices and interactions, including multi-modal feedback, Application of the above, for example in areas such as education, rehabilitation, medicine, computer-aided design, skills training, computer games, driver controls, simulation, and visualization.
