Treatment of the ankylosed mandibular permanent first molar: a case study.

The treatment of ankylosed teeth has been reported. While the diagnosis of the condition can be readily made, the etiology remains unknown. Treatment of these teeth is aimed at preventing malocclusions and periodontal defects from developing. Once diagnosed, these teeth require careful evaluation and prompt treatment. Delaying treatment nearly always results in a less favorable outcome. In the case presented, it was thought best to attempt luxation rather than to extract the mandibular first molar to overcome the ankylosis. This reasoning was based on the fact that there was adequate space for the first molar to erupt into and the maxillary first molar had not over-erupted. Selection of the best mode of treatment will depend upon many factors, including space available for the eruption of the involved tooth, inclination of the tooth, stage of development of the dental arches and overall health of the involved tooth.
