    • A lingual placement device for positioning orthodontic attachments, such as, brackets, on the lingual side of teeth is described. The device includes a handle which is pivoted to a handle extension to permit access to both anterior and posterior teeth in the mouth of a patient. A tooth engagement plate, which engages the front side of a tooth, is pivoted about a horizontal transverse axis. An orthodontic bracket holder is mounted to the handle extension for both horizontal and vertical movement to permit placement of an orthodontic bracket on the lingual side of a tooth. In operation, the tooth engagement plate is positioned in engagement with the front side of the tooth, the bracket is located in its desired position adjacent the lingual side of the tooth by up and down movement of the handle and vertical movement of the bracket holder. The bracket, to which adhesive is applied, is drawn into engagement with the lingual side of the tooth to grip the tooth between the front plate and the bracket until the adhesive has cured sufficiently to adhere the bracket to the tooth. The bracket then is released and the device is removed from the mouth.
    • 描述了用于在齿的舌侧上定位正畸附件(例如支架)的舌部放置装置。 该装置包括手柄,该手柄枢转到手柄延伸部,以允许进入患者口腔内的前牙和后牙。 与齿的前侧接合的齿接合板围绕水平横向轴线枢转。 正畸托架支架安装在手柄延伸部上以进行水平和垂直运动,以允许将正牙托架放置在牙齿的舌侧上。 在操作中,齿接合板定位成与齿的前侧接合,托架通过手柄的上下移动和托架保持器的垂直运动位于邻近牙齿的舌侧的所需位置。 将施加有粘合剂的托架拉入与牙齿的舌侧接合以夹持前板和支架之间的齿,直到粘合剂已经充分固化以将支架粘附到牙齿上。 然后将支架释放,并将装置从口中取出。
