The patient doesn't complain, but that's really the only difference for these dental students practicing in the world of mixed reality.
病人从不抱怨，这是这些牙科学生在混合现实世界中练习同进行真实手术的唯一区别。
The mixed part of the process is this dental training head.
这个过程的混合部分在于用于牙科训练的头模。
It's not much to look at and without the virtual reality goggles, it's even less impressive.
它本身没什么特别之处，不戴上虚拟现实头显的话，就更不会给人留下多少印象。
But when you place the VR over the fake head, a process called augmented reality, suddenly it's a real mouth and a real person.
但是，当你将VR头显放在头模上面时，这个过程就是增强现实，突然之间，你看到的是一张真正的嘴和一个活生生的人。
"I hope this technology will give more visual information
“我希望这项技术能够提供更多的视觉信息，
and help students imagine and understand what needs more caution during practice surgeries
帮助学生想象和了解在临床手术中，哪些地方需要加倍谨慎。
by revealing more information on non-visible areas.
当然前提是通过揭示不可见区域的信息。
This is something a textbook can't offer."
这是教科书无法提供的东西。”

The developers hope the training program will make dentists more comfortable with patients
研发人员希望这一培训项目能使牙科医生更加熟悉不同患者的情况，
and let them practice all kinds of different dental scenarios.
帮助他们模拟练习各种牙科情景。
"Usually we would have to use our imagination to determine the area that needs treatment
“通常我们必须运用想象力来确定需要治疗的区域，
and then think that information with what we are physically seeing in our patients,
然后根据我们在病人身上看到的症状来思考这些信息，
a process that requires experience, intuition and good sense.
这个过程需要经验、直觉和敏锐的洞察力。
But the merit behind this technology is that anyone can see the same information and implement treatment safely."
但这项技术的优点是任何人都可以看到相同的信息，并安全地实施治疗。”
The developers say this is the first time virtual reality simulation has been successfully paired with augmented reality.
研发人员表示，这是虚拟现实模拟和增强现实首次实现成功对接。
The Morita team says they expect to have a product ready for universities and hospitals in about 2 years.
Morita团队表示，他们希望在大约2年内将产品研制成功，供大学和医院使用。
