Ectopic Eruption (Part II)

Another common situation where a permanent tooth is not in its normal path of eruption is when the first molars (six year molars) are attempting to come in too far forward thus resorbing the roots of the baby tooth that is ahead of it. If this situation is allowed to continue, then it will cause the baby tooth to be lost prematurely. The offending permanent molar will then erupt too far forward, thus leaving no room for the bicuspid to erupt later. I have found that by pushing the molar back before the baby tooth is lost, then the baby tooth can be retained until its normal time to come out. The procedure is call distalization. I connect orthodontic bands on a couple of molar teeth and connect them to a spring. I then bond a hook on the chewing surface of the offending tooth and engage the spring. This pushes the tooth back into its normal position. I remove the spring and allow the tooth to erupt normally. The process takes from two to four months.
