Abstract
Placement devices for positioning orthodontic attachments, such as, brackets, on the lingual and facial side of teeth are described. A tooth engagement plate or other member, which engages the facial side of a tooth for lingual placement or the lingual side for facial placement, is mounted for pivotal movement at least about a horizontal transverse axis. An orthodontic bracket holder is mounted to a handle for both horizontal and vertical movement to permit placement of an orthodontic bracket on the opposite side of a tooth to that engaged by the plate. In operation, for lingual placement, the tooth engagement plate is positioned in engagement with the facial 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. The same procedure is used for facial placement, except that the plate engages the lingual side and the bracket is drawn into engagement with the facial side.
