Classification Case report
  “impacted” means that a tooth either has not erupted when expected or a tooth that cannot erupt because it does not have room or may be coming in the wrong direction or position. What causes an impacted tooth may not be known. Genetics can play a role, so if a parent had an impacted tooth, their child may experience the same problem.
    The impacted tooth usually happened at third molars, maxillary canine and second premolar etc. Fixing an impacted tooth can range from relatively simple to complicated. It all depends on the extent of the problem. In this report, a growing 12 year-old girl with bilateral mandibular second molars impacted was treated with different orthodontic methods. The mesial tilting second molars were uprighted by using the twisted copper wire and the Ni-Ti wire in the other side. These two local orthodontic methods were both preformed with simple ways, but they still needed to align with the archwire in the finished stage.
    Although the tooth buds of the third molars existed on the distal side of the impaceted second molars, they didn’t interfered the uprighting pathways of the tilting teeth in this case. Another issue that we can notice was the second molars had the erupting potential during treatment period, and it might shorten the treatment time. We will keep following this case and treat other space problems in the suited time.
