A case of extreme distal migration of the left maxillary canine is reported. The canine had erupted buccal to the contact area between the left second premolar and first molar. Past reports of similar ectopia are reviewed.
Pathologic tooth migration (PTM) is a common complication following moderate to severe chronic periodontitis, which lead to the undesirable consequences such as traumatic occlusion and impaired aesthetic appearance. Multidisciplinary approach had been successfully used in overcoming the problem. However, since periodontal tissue support is reduced in PTM, further migration of teeth may occur as they were always subjected to the external forces such as occlusion and soft tissue pressure during function. This case report described a 41 year-old male with a further migration of his upper right central incisor after periodontal therapy. After multidisciplinary approach was carried out to overcome the problem and the tooth was on stable condition, permanent splinting was placed to secure the tooth.
