tooth wear

Users wear a specially designed headband which is hooked up to a Blue tooth device that wirelessly sends commands to a Nokia N73 mobile phone.

用户需要佩戴一个连接蓝牙设备的特制头部饰带，通过该装置向诺基亚N73手机发送无线信号，然后回应大脑发出的信号。

Tooth wear progresses throughout one's life.

牙齿磨耗（Tooth wear）贯穿人的一生。

Objective : To investigate the metal-porcelain in the fixed prosthesis treatment of advanced tooth wear.

目的: 观察金属烤瓷牙修复面重度磨耗的临床治疗效果.

The specimens made from Bayer tooth, thermosetting plastic, copper base alloy, titanium and its alloy have relatively good wear resistance as well and are thus idea prosthetic materials.

拜尔牙、热固塑料、铜基合金、钛及钛合金是较为理想的牙科修复材料；

Conclusions: The 3-d computer assistant measure system can accomplish the analysis and measurement to the tooth wear, and further research in clinical application is required.

结论：该系统能进行牙磨耗图像的三维分析计算，其临床广泛的推广应用还有待于进一步研究。

The results show that in the case of the same cutting resistance, pick-shaped teeth enjoys advantages over knife-shaped teeth, as a result of it better combined performances, such as freedom of fragment, the lower tooth cost and wear-proof.

结果表明：在截割阻力相同的情况下，镐形齿具有不易被击碎、齿耗低、耐磨等优点，其综合性能优于刀形齿。
