Description

颜色分区式牙体预备训练模型 技术领域
本发明属于口腔临床医学技术领域，涉及口腔医学实验教学中对专业人士进行牙体预备训练的模型。
背景技术
在口腔临床工作中，龋病等导致的牙体缺损、牙齿着色、牙列不齐、隐裂牙等是常见的临床问题。这些问题的解决过程中需要对牙体组织做特定的磨削(即牙体预备)，然后进行修复以达到治疗的目的。手部操作技能决定了口腔医师的处置能力，因此在口腔医学专业人员的培养过程中，实验教学是最为重要的组成部分之一。
传统牙体预备实验教学利用人脱落或拔除的牙齿(离体牙)进行训练，其优势在于磨除时的手感同临床操作一致。但缺点十分突出，包括来源困难、牙位随机性大、牙体磨耗以及龋坏导致牙体解剖结构破坏或不典型、训练不可重复等，且评估方式只能采用肉眼观察，评估结果受评估者的主观意念影响较大。为了弥补离体牙的上述不足，国内外许多牙科教育行业器材供应商推出了不同牙位的塑料牙，供训练者使用。现有塑料牙以用普通塑料制作为主，其优势在于牙体外形同人牙体外形一致、解剖结构清晰典型、同一牙位可重复练习、价格合理等，不足之处是训练时磨削目标不够明确，评估方式仍然只能采用肉眼观察，难于使评估结果客观，从而不利于引导受训者循序渐进提高操作准确度。此外，硬度与真实牙硬度有一定差异，导致手感有一定区别。
为了使牙体预备的评价更为客观，近年市面上陆续出现了数字化口腔教学评估系统，其优势在于通过对牙科涡轮机加载定位器以及外置探头，对术者的操作进行客观的过程评价；或是通过外置扫描仪对磨削完成的牙体模型体外扫描进而实现客观的结果评价。然而其也具有一定的局限性，例如过程评价的设备价格高昂(约75万元人民币一台，且训练时需一人一机)、定位器的加载导致涡轮机后部重量大幅增加进而对受训者的操作带来明显的影响、探头信号容易被物体遮挡中断、占地面积较大等；结果评价设备在工作时必须把牙模取出放入扫描器进行影响评估的流畅性、评估结束后受训者还是不知道具体如何改进、评估过程操作较为复杂。
发明内容
本发明的目的在于克服现有技术的不足，提供一种颜色分区式牙体预备训练模型，以便使受训者磨削目标明确，并可实时客观反馈训练结果，引导受训者循序渐进提高操作准确度。
本发明所述颜色分区式牙体预备训练模型，由对应于各牙位的牙体预备训练模型组成，对应于各牙位的牙体预备训练模型均由固定部段和预备训练部段构成，所述预备训练部段是由材料相同、颜色不同的目标区域、误差允许区域和禁止区域结合成的一体化结构，所述目标区域是训练时需要磨除的区域，所述误差允许区域是训练时可以磨除的区域，所述禁止区域是训练时不能磨除的区域，误差允许区域位于目标区域与禁止区域之间，且环绕目标区域。
上述颜色分区式牙体预备训练模型，其误差允许区域的厚度(即误差范围)可根据受训者的受训程度或考察要求设定，一般为0.05～0.8mm。在此误差范围内，可设计和制备不同厚度误差允许区域的牙体预备训练模型，满足不同层次受训者的需求。
上述颜色分区式牙体预备训练模型，包括人的20颗乳牙预备训练模型或32颗恒牙预备训练模型。
上述颜色分区式牙体预备训练模型，制作材料为工程塑料，以便使其硬度更接近真实牙，受训者通过训练后在临床上的操作不因训练与临床的手感差异受到影响；所述工程塑料可以是聚甲醛(polyformaldehyde，缩写为POM)、ABS塑料(丙烯腈-丁二烯-苯乙烯塑料)等。
上述颜色分区式牙体预备训练模型的制备方法为注塑或3D打印。
本发明所述颜色分区式牙体预备训练模型具有以下有益效果：
1、由于本发明所述牙体预备训练模型的预备训练部段含有颜色不同的目标区域、误差允许区域和禁止区域，因此使用该牙体预备训练模型进行训练，受训者磨削目标明确，并可实时客观反馈训练结果，避免了指导教师或评估人员由于主观因素造成的误差，统一了训练标准。
2、使用本发明所述颜色分区式牙体预备训练模型进行训练，受训者可以自主练习及评估，并根据牙体颜色分布及时作出改正，循序渐进提高操作准确度，因而不仅可大大节约师资，而且单位时间内的训练量可以显著提升，让实验教学过程变得更加高效、简单。
3、由于使用本发明所述牙体预备训练模型可实时客观反馈训练结果，因而不需通过数字化口腔教学评估系统对训练结果进行评价，不仅可节约设备购买费用，而且训练结果的评价方式更为简单、流畅，同时受训者知道具体如何改进。
4、由于本发明所述牙体预备训练模型的制作材料为工程塑料，因而与现有塑料牙体预备训练模型相比，其硬度更接近真实牙，可使受训者通过训练后在临床上的操作不因训练与临床的手感差异受到影响。
5、由于本发明所述颜色分区式牙体预备训练模型可以3D打印制备，因而训练内容可以个性化设计，与临床病例数据结合，使训练更贴近临床实际情况，进一步改善训练效果。
