最近推出了一种类似于贝壳或顶针冠的铜“带壳”。与标准铜带相比，它在使用建模化合物或弹性体为单个预备牙齿制作印模方面具有一定的优势。带壳有一个带有单个穿孔的“盖子”，并配有花边。它的规格、尺寸和长度与标准带相同。* 使用弹性材料制作印模时，盖子无需堵塞一端。在制作复合印模时，它会限制印模材料，并在加热、就座和移除过程中改善方向和控制。带壳还有助于组织回缩。预退火的带壳和造型化合物带的花边边缘有助于选择和调整带，并有利于其放置以进行初步装配。 1. 仔细装饰后，将带子的边缘斜切，并在其表面进行标记以供识别。使“盖子”凹陷，为手指 01 的指甲固定在底座上提供凸起的边缘（图 1）。盖子应距牙齿准备好的切缘 01 咬合面至少 1/4 英寸。对成品乐队进行多次试座。
A copper “band-shell,” similar to the shell or thimble crown, has recently been made available. It offers certain advantages over the standard copper band for making an impression of a single prepared tooth with modeling compound or elastomer. The band-shell has a “lid” with a single perforation and is supplied with a festooned border. It is supplied in the same gau, ye and length as that of the standard bands.* The lid eliminates the need to plug one end while making an impression with an elastomeric material. In making a compound impression, it confines the impression material and permits improved direction and control during heating, seating, and removal. The band-shell also assists in tissue retraction.PREANNEALED BAND-SHELL AND MODELING COMPOUND The festooned margin of the band aids in selecting and adapting the band and facilitates its placement for preliminary fittings. 1. After careful festooning, bevel the edges of the band, and mark its facial surface for identification. Indent the “lid” to provide a raised rim for finger 01 fingernail holds in seating (Fig. 1). The lid should clear the prepared incisal 01 occlusal surface of the tooth by at least 1/4 inch. Trial seat the finished band several times.
