最近的一项调查显示，在口腔种植手术中发生的事故中，近30%与骨小梁区的下颌管有关，其中大多数与钻孔过程有关。其中一个已知的原因是由于临床医生缺乏知识和经验。为了克服这个问题，我们通过教育的方法，提出并开发了一个新的系统，主要是为口腔学院的学生，重点是钻下颌骨小梁骨。该系统以口腔种植手术训练模拟器的形式出现，使学生能够在钻孔过程中感受到反作用力。然后，由专家临床医生和牙科学院的学生评价开发的系统。共有8名临床医生和24名学生测试了钻削力数据库的所有三个样本。要求临床医生根据刚度量表描述钻削力，而要求学生在钻削第三个样本之前先钻削两个样本。他们被要求根据之前样品的比较绘制第三个样品。基于所做的评估，发现钻削期间感测到的力的量化可以从钻削力和钻削速度的组合导出，钻削力和钻削速度通过与先前或累积的钻削经验进行比较的相对值而获得。本研究结果亦显示，口腔植牙手术训练模拟器可帮助学生透过重复使用及练习，了解不同骨质对钻削力觉的差异。
A survey done recently showed that almost 30 percent of the accidents occurred during oral implant surgery were concerned with the mandibular canal in the trabecular bone region and most of them were related to the drilling process. One of the reasons known is due to the clinicians’ lack of knowledge and experience. In order to overcome the problem, through the educational approach, we proposed and developed a new system mainly for dental colleges’ students, by focusing on drilling the mandibular trabecular bone. The system comes in the form of an oral implant surgery training simulator that enables student to sense the reaction force during drilling. The developed system was then evaluated by expert clinicians and dental college’s students. A total of 8 clinicians and 24 students tested all three samples of drilling force database. The clinicians were asked to describe the drilling force based on a stiffness scale while the students are required to drill two samples first before drilling the third sample. They were asked to sketch the third samples based on the comparison of previous samples. Based on the evaluation done, it was found that the quantification of force sensed during drilling could be derived from the combination of drilling force and speed obtained through the relative value of comparison with the previous or accumulated experience of drilling. The results of this study also indicate that the oral implant surgery training simulator could help students learn the difference of drilling force sense dependent on the bone quality through repeated usage and practices.
