Anterior cross bites are one of the most common malocclusions, and fortunately, one of the easier ones to correct for most animals. Following are a few options for correcting anterior cross bites:
Finger Springs: For small to medium breeds, bonded orthodontic bands with back action finger springs can be cemented in place, loaded, and no further action is needed for the doctor, or the client. Within a matter of days or weeks, notable tooth movement will occur. These devices are non intrusive, well tolerated and require little maintenance.
Expansion Devices: Medium to large breed dogs often need a more aggressive approach to tooth movement. On these cases, we utilize a standard orthodontic expansion screw that is anchored on the maxillary canine teeth, which are used to hold a lingual pad that engages the lingual surfaces of the incisors. Once cemented in place, the screw is turned to move the pad, pushing the anterior teeth out correcting the alignment. These devices will need periodic adjustment, and will need daily cleaning, though they are generally well tolerated.
Labial Arch Bars: Depending on the age, tooth movement in large breed animals can be especially challenging. In these cases, we often recommend a cast labial arch bar, with buttons to secure elastic power chain. These elastic ligatures are anchored to the tooth via a bonded button or bracket. Once pulled out labially towards the bar, bar position will determine the amount and direction of tooth movement, though small adjustments can be made by the clinician with ligature angles.
