    • An oral hygiene device in the form of an elongated strip of resilient material having in use a generally arcuate or U shape for insertion into a user's mouth and having a pair of opposed jaw members (10, 11; 12, 13) which receive the user's teeth. A connecting portion (20) extends between the jaw members so that the jaw members move towards each other upon pressure being applied to the connecting portion (20) by the user's teeth biting onto the connecting portion so as to press the jaw members (10, 11; 12, 13) into engagement with the front and back faces of the teeth. Further relative movement of the user's upper and lower teeth with a grinding, rotary or reciprocating movement causes the opposed jaw members to rub against and clean the front and back faces of the teeth. The inner faces (16, 17; 18, 19) of the jaw members (10, 11; 12, 13) which face each other and engage with the teeth are composed of a mildly abrasive material. The connecting portion (20) includes a raised structure (21, 22, 31) projecting into the region (14, 15) between the opposed jaw members (10, 11; 12, 13) so that the raised structure (21, 22, 31) can engage in and assist dislodgement of particles from the facing teeth surfaces of particularly the premolars and molars of the upper and lower jaws of the user. The connecting portion (20) is provided with a cavity (23) or a central core region (36) of softer material than the surrounding material of the connecting portion (20) so as to facilitate deformation.
    • 一种具有弹性材料的细长带形式的口腔卫生装置,其使用中大致为弧形或U形,用于插入使用者的口中并具有一对相对的夹爪构件(10,11; 12,13),其接纳使用者的 牙齿。 连接部分(20)在钳口构件之间延伸,使得钳口构件朝着彼此移动,当使用者的牙咬在连接部分上时,压力被施加到连接部分(20)上以便将钳口构件 11; 12,13)与牙齿的前表面和后表面接合。 使用者的上下齿与磨削,旋转或往复运动的进一步的相对移动导致相对的夹爪构件摩擦并清洁牙齿的前表面和后表面。 夹爪构件(10,11; 12,13)的彼此面对并与齿接合的内表面(16,17; 18,19)由轻度研磨材料构成。 连接部分(20)包括突出到相对的夹爪构件(10,11; 12,13)之间的区域(14,15)中的凸起结构(21,22,31),使得凸起结构(21,22, 31)可以参与和协助从特定的使用者的上颚和下颚的前磨牙和磨牙的面对牙齿表面移除颗粒。 连接部分(20)设置有比连接部分(20)的周围材料更软的材料的空腔(23)或中心芯区域(36),以便于变形。
