目的    探讨Simodont虚拟仿真系统在口腔住院医师规范化培训中的应用效果。方法    选取于湖南中南大学湘雅口腔医院进行住院医师规范化培训的2020级住院医师20名,采用随机数字表法分为研究组和对照组,每组各10名。研究组和对照组住院医师分别使用Simodont虚拟仿真系统和传统仿头模培训系统进行G.V.Black Ⅱ类洞的制备训练。采用专业化评分和数字化评级比较两组训练效果,并对研究组住院医师进行Simodont虚拟仿真系统使用情况调查。结果    两组住院医师分组训练前的专业化评分及数字化评级比较,差异均无统计学意义(均P > 0.05)。研究组住院医师分组训练后的专业化评分和数字化评级均显著提高,且优于对照组,差异均有统计学意义(均P < 0.05)。研究组10名住院医师均完全认同使用Simodont虚拟仿真系统进行口腔科操作训练是未来的发展趋势,且认为Simodont虚拟仿真系统比传统仿头模更容易操作;但大部分住院医师也同样认为Simodont虚拟仿真系统对操作者的操作精度要求更高。结论    Simodont虚拟仿真系统的应用有助于提高口腔住院医师的操作水平。建议在充足的Simodont虚拟仿真系统专业培训前提下,将其广泛应用于口腔科临床操作训练。  相似文献

虚拟现实技术在口腔诊疗操作培训中的应用   总被引:1,自引:0,他引:1  
虚拟现实(VR)是近年来迅速发展起来的一项高新技术,其操作技能模拟器不但可以模拟实际临床中的常规病例和疑难病例,供学生反复练习其诊疗要领,还可以连续记录操作过程的三维运动和力数据,进行回放观摩和分析,使教学、训练和考核环节变得可量化和标准化,不依赖于特定教师的经验,便于教学和考核;具备沉浸感、想象性和交互性等本质特征.在口腔医学教育领域,VR技术通过建立集成力学和视觉显示的虚拟仿真环境,逼真地再现了口腔医师对真牙操作时的感觉和信息.VR技术在口腔医学各专业领域的操作技能培训中的应用,将改善当下业界仍主要采用体外牙和人工牙来训练口腔医师触觉感知能力及操作技巧的教育环境,有望探索出一条培训口腔医师操作技能的新方法.  相似文献

在三维计算机辅助设计(CAD)技术已经普及的情况下,如何更好地设计产品,就涉及到计算机辅助工程(computer aided engineering,CAE)技术。CAE技术是计算机技术与工程分析技术相结合而形成的新技术,它以CAD系统确定的数据为基础,利用计算机的分析计算和仿真功能,可预测产品性能、发现设计缺陷、优化产品设计、减少物理样机数量、提供产品性能便于多领域人员包括非技术人员之间的讨论、协作。CAE与CAD、计算机辅助制造(CAM)的不同之处在于CAD、CAM主要用于解决产品的结构设计和生产制造的问题,而CAE主要用于对产品进行模拟和分析,由传统的分析和校核扩展到优化设计属于更高层次的应用。其常用的两种技术为有限元分析和优化设计。本文就CAE技术及其在口腔种植体中的应用作一综述。  相似文献

OBJECTIVE: The study addressed the impact of the frequency of tutorial-enriched augmented visual feedback, provided by a virtual simulation system (DentSim), on the skill acquisition for a cavity preparation task in novice dental students. METHODS: Thirty-six subjects were assigned to two training groups and a control group. The task consisted of a geometrical cross preparation on the lower left first molar. All subjects performed a pre-test to assess their basic skill level. The training groups received simulation feedback, enriched with tutorial information, across acquisition. One group trained under continuous augmented feedback, while a second group trained under an intermittent (66% of the time) feedback. At both 1-day and 4-month interval, subjects performed a retention test to explore learning specific effects. Two transfer tests were added to assess the extrapolation of the learned skills to an adjacent molar. All tests were performed in the absence of feedback. A control group performed all the tests, without preceding training. All preparations were graded by the simulation system. RESULTS: The training groups performed similarly across acquisition and improved with practice (ANOVA, P<0.001). After 1 day and 4 months of no practice, the training groups outperformed the control group on a retention test (ANOVA, P<0.001) and transfer test (ANOVA, P<0.001). CONCLUSIONS: Performance and learning of a cavity preparation task on a simulation unit was independent of the frequency of tutorial-enriched augmented visual feedback within the range tested. Training sessions on a simulation unit could be alternated with training sessions in the traditional phantom head laboratory.  相似文献

Objectives: The profession of dental hygienist is one of the few in which the primary function of the practitioner is to prevent oral disease and to promote the well‐being of patients. The aim of this study was to investigate clinical training conditions in schools of dental hygiene in eight countries (the USA, Canada, the UK, Sweden, Denmark, Thailand, South Korea and Japan). Methods: In 2006, we sent out a questionnaire in which we asked dental hygiene schools about how they educate dental hygiene students. Results: The techniques taught to students in schools in Western industrialised nations, such as the USA, Canada, Denmark, the UK and Sweden, were mainly related to dental preventive measures and dental health guidance. By contrast, training schools in South Korea and Japan placed less emphasis on dental preventive measures and dental health guidance. Dental hygienists in Thailand are trained to perform local anaesthesia and to fill and extract deciduous teeth although the country does not have a specific qualification system. Conclusions: The contents of clinical training and education in schools of dental hygiene differ greatly among countries.  相似文献

The main objective of this study was to compare the stability of the surgery-first and surgery-late approaches according to the standardized centre protocols, by three-dimensional evaluation after 1 year of follow-up. A retrospective study was designed that included a test group (surgery-first protocol) and a control group (surgery-late protocol), with a follow-up period of at least 1 year (average 14 months; range 12–24 months). Stability was evaluated using linear and angular measurements by superimposing cone beam computed tomography images obtained at specific points in time: preoperatively, 1 month after surgery, and at the end of the orthodontic treatment. A total of 56 patients with a mean age of 32.2 ± 11.1 years were included in the study. After surgery there were significant changes in all of the measurements in at least one dimension in both groups (except for the transverse maxillary dimension), which remained stable at the end of the treatment, with no statistically significant differences between the two groups. At the 1-year follow-up, both groups presented a SNA angle relapse; this relapse was more significant in the surgery-late group (P = 0.031) and was present only in Class III patients (P = 0.013). In conclusion, an equivalent three-dimensional stability between surgery-first and surgery-late protocols was demonstrated after 1 year of follow-up when eligibility criteria were strictly adhered to.  相似文献

Most dental foundation year 2 (DF2) training takes place in oral and maxillofacial surgery (OMFS) units. We did a survey of DF2 trainees in these units by telephone interviews and an online questionnaire to find out about their experience of training and their career aspirations. A total of 123 responded, which is roughly 41% of the total estimated number of trainees. Trainees applied for these posts mainly to improve their dentoalveolar skills (50%), and this was cited as the best aspect of the training. Most (81%) were on-call at night and this was generally thought to be a valuable training experience (77%), but 20% thought that it was the worst aspect of the job. Most did not regret taking up the post although the experience had caused 75% to alter their intentions about their future career; general dental practice was the commonest choice. In conclusion, trainees are generally satisfied with their training and these positions have guided their choices about future careers.  相似文献
