针对计算机辅助口腔修复体设计中的缝合问题,根据修复体腔底表面和上表面的生物医学特征,提出了一种基于拉链啮合机制和最小化全曲率能量函数的缝合算法.该算法首先采用由局部最优化权值驱动的虚拟拉链,对修复体腔的底表面和上表面边界进行拉合,得到对应的初始缝合曲面片.其次,对初始缝合曲面片进行细分优化,并根据牙齿的生理医学特性,对缝合曲面片进行变形调整,构造出符合实际生理医学特征的缝合曲面片,实现修复体腔底表面和上表面的光滑连续缝合.实验结果表明,利用所提方法设计出的修复体在形态和配合精度上,均能满足临床口腔医学要求. 相似文献

主要通过文献资料法、访谈法、问卷调查法、数理统计法、逻辑分析法,从中学生体能素质审视家庭对学生“三高”形成的影响,即：龋齿率高、近视率高、肥胖率高．调查研究发现,现在中学生体质正在逐渐下降,引起这一下降的原因有很多,通过研究发现：家庭是中学生的“三高”的形成的主要因素之一．因此,我们要提高学生体质,重视家庭教育． 相似文献

Tooth morphology has a pivotal role in the dental curriculum and provides one of the important foundations of clinical practice. To supplement tooth morphology teaching a three-dimensional (3D) quiz application (app) was developed. The 3D resource enables students to study tooth morphology actively by selecting teeth from an interactive quiz, modify their viewpoint and level of zoom. Additionally, students are able to rotate the tooth to obtain a 3D spatial understanding of the different surfaces of the tooth. A cross-over study was designed to allow comparison of students’ results after studying with the new application or traditionally with extracted/model teeth. Data show that the app provides an efficient learning tool and that students’ scores improve with usage (18% increase over three weeks, P < 0.001). Data also show that student assessment scores were correlated with scores obtained while using the app but were not influenced by the teaching modality initially accessed (r2 = 0.175, P < 0.01). Comparison of the 2016 and 2017 class performance shows that the class that had access to the app performed significantly better on their final tooth morphology assessment (68.0% ±15.0 vs. 75.3% ±13.4, P < 0.01). Furthermore, students reported that the 3D application was intuitive, provided useful feedback, presented the key features of the teeth, and assisted in learning tooth morphology. The 3D tooth morphology app thus provides students with a useful adjunct teaching tool for learning dental anatomy. Anat Sci Educ 00: 000–000. © 2018 American Association of Anatomists. 相似文献

Student struggles in gross anatomy coursework at the professional level can result in hours of remediation along with a need to allot time and other resources by both the student and the faculty. Since this course typically occurs in the first semester of the first year, programs can turn to admissions data to try to determine which of these students may struggle. This study looked at two years of medical (n = 280) and dental (n = 78) students to determine if there is a relationship between pre-admissions anatomy coursework and performance in gross anatomy at the professional school level. Students provided data regarding their past anatomy coursework and final grades in professional school gross anatomy courses were obtained. In addition, students responded to questions regarding their feelings of preparation and how they valued the prior anatomy coursework as it related to the professional course. Statistical analysis showed no difference in final course grade between students with and without prior anatomy in either program. Counter to the numerical data, 96.6% of the students in the study recommended an anatomy course prior to pursuing a health science degree. The primary reasons given for this recommendation were the benefits of repeated content exposure, knowledge of the anatomy terminology, and decreased stress regarding the course. The results from this study suggest that the benefits of prior anatomy may be seen more in the students’ stress and quality of life rather in the numerical performance of course grades. 相似文献

喉音与牙音是五音中最为活跃的两个音类,这种活跃不仅体现在近古以后喉牙音的大量腭化与归零上,更体现在喉牙音内部的声转及喉牙音与其他音系的声转上。声转是喉牙音中最常见和最重要的语音现象,它对谐声、通假、声训、古书异文、一字多音等诸多语言现象有着重要的作用和影响。 相似文献

The first four levels of Bloom's taxonomy were used to create quiz questions designed to assess student learning of the gross anatomy, histology, and physiology of the gastrointestinal (GI) system. Information on GI histology and physiology was presented to separate samples of medical, dental, and podiatry students in computer based tutorials where the information from the two disciplines was presented either separately or in an integrated fashion. All students were taught GI gross anatomy prior to this study by course faculty as part of the required curriculum of their respective program. Student responses to the quiz questions were analyzed to assess both the validity of Bloom's cumulative hierarchy and the effectiveness of an integrated curriculum. No statistically significant differences were found between quiz scores from students who received the integrated tutorial and from those who received the separate tutorials. Multiple regression analyses provided partial support for a cumulative hierarchy where scores on the lower levels of Bloom's taxonomy predicted scores on higher levels. Notably, in the majority of regression analyses, the comprehension score was the key foundational predictor for application and analysis scores. This study supports the suggestion that educators increase the number of comprehension level questions, even at the expense of knowledge level questions, in course assessments both to evaluate lower order cognitive skills and also as a predictor of success on questions requiring application and analysis levels of the higher order cognitive skills of Bloom's taxonomy.
