[The arrangement of trans-septal fibers in rotated and non-rotated emerged teeth in beagle dogs].
Transseptal fibers of the periodontal ligament are thought to play a role in relapse after orthodontic correction of rotated teeth. The aim of this study was to compare the location of the attachment site and the arrangement of the transseptal fibers in rotated emerged and non-rotated emerged teeth. In five dogs, unilaterally, the first upper premolars were reimplanted into a rotated position, before emergence. Histological evaluation showed that in the experimental as well as in the control specimens transseptal fibers developed. In all cases transseptal fibers bridged the shortest distance between two adjacent teeth. It was concluded that the attachment site of the transseptal fibers is not determined by tooth anatomy itself, but by the tooth position and its orientation in the dental arch during transseptal fiber development.
