摘要： A toothbrush construction is described in which a bristle head is made moveable with respect to a handle and contains adjustable springs to permit presetting of the brushing pressure. The springs are so formed as to have a break away feature. The user is thus made aware whenever he exerts more than the preset pressure and can learn to brush at a pressure which permits good cleansing and minimizes brushing damage to his teeth and gingival tissue.

摘要： An adjustable band for orthodontic use which is formed of a strip of relatively soft material, such as annealed metal or flexible plastic, is provided. In one embodiment, one end of the band contains tabs which are formed into a shackle and flexible projections. The other end of the band comprises a tang which contains rectangular indentations into which the projections fit. In another embodiment of the invention, the band is formed in a one-piece construction of molded plastic. The band of the second embodiment comprises a strip having a tang portion on one end and a shackle portion on its opposite end, where the shackle incorporates a slot through which the tang can be inserted. In both embodiments, when the tang is placed into the shackle, a cylindrical loop is formed which can be placed over a tooth and drawn into approximately the diameter of the tooth. Further tightening creates forces which shape the band around the tooth to match the contour of the tooth.
摘要翻译：提供了由诸如退火金属或柔性塑料的相对软的材料条形成的用于正牙使用的可调节带。在一个实施例中，带的一端包括形成为钩环和柔性突起的突片。带的另一端包括一个包含凸起配合的矩形凹陷的柄脚。在本发明的另一个实施例中，带形成为模制塑料的一体式结构。第二实施例的带包括一条带，其一端具有一个柄脚部分，而另一个端部具有一个钩环部分，其中钩环包括一个插槽，通过该插槽可插入柄脚。在两个实施例中，当将柄脚放置在钩环中时，形成圆柱形环，其可以放置在牙齿上并且被拉入大致直径的牙齿。进一步的紧固产生使牙齿围绕牙齿成形以匹配牙齿轮廓的力。
