摘要：

背景：在临床口腔正畸领域中，磨牙带环起着非常重要的作用，但传统带环存在试戴繁琐、需提前分牙、占用较大间隙及易导致带环磨牙牙周炎症等缺点。因此，有些学者使用磨牙颊面管来代替磨牙带环，但其存在脱落率相对高，不能在其上制作横腭杆、Nance弓等附件问题。

目的：发明一种新型磨牙C形开口纳米带环(已获得中国国家发明专利，专利号为ZL2011 10057699.1)作为临床常用的磨牙固位装置以解决上述问题。
方法：制作0.18-0.20 mm厚度、一定长度的预成型不锈钢条带，将不锈钢条带制作成具有颊侧面、舌侧面、远中面3个面及颊舌两侧游离端向近中面延伸的C形开口形状。为增强固位，在其内表面涂覆纳米级羟基磷灰石，并在临床使用时通过树脂加强型玻璃离子黏固剂与磨牙牙冠黏结在一起。

结果与结论：新型C形开口带环由带环的颊侧面、带环的舌侧面、带环的远中面、带环的颊面管、带环近舌轴线角处向近中面的延伸段、带环近颊轴线角处向近中面的延伸段组成；从设计方式上看，与传统带环相比，新型带环具有其自身的优点，如无需提前分牙及反复试戴，对牙周组织刺激小等。

Abstract:

BACKGROUND: In the field of orthodontics, molar bands play an important role. But traditional bands have some weakness difficult to be solved in clinical use, for example, trying on cumbersomely, having to separate the adjacent teeth beforehand, occupying bigger space and tending to cause periodontitis of molars with bands. So some clinicians use a buccal tube instead of the molar band, but it has relatively high losing rate and cannot be fixed with Transpalatal Arch and Nance.

OBJECTIVE: To invent a new open “C”-shaped molar band with nanomaterial (patent number: ZL201110057699.1) to solve the above problems as a common molar appliance. 
METHODS: We made some stainless steel strips of 0.18-0.20 mm thickness and a certain length. The stainless steel strips were made to the new bands composed of buccal, lingal, distal surface and bilateral extention caused by removable parts extending to mesial surface. In order to improve retention force, its inner surface was coated by nano-hydroxyapatite and it bound to the molar crown by resin reinforced glass ionomer cements in clinical use.
RESULTS AND CONCLUSION: The new open “C”-shaped molar band with nanomaterial overcomes shortcomings of conventional band and buccal tube. From the design, in contrast with traditional band, it not only has no need to separate teeth beforehand and to try on repeatedly, but also less stimulates periodontal tissues. So the new band can be more suitable for clinical use.
