20 Tooth movement and related problems

Case 1

Summary

Darren, a 13-year-old boy, has been undergoing upper removable appliance therapy for 6 months to retract and align image, following extraction of image. Tooth movement has been very slow with no movement recorded at the last two visits.

Tension zones

Following initial application of a light force, the blood vessels vasodilate and the periodontal ligament fibres are stretched, while fibroblast and preosteoblast proliferation occurs. The stretched fibres become embedded in osteoid, which later mineralizes. The normal periodontal ligament width is eventually regained by simultaneous collagen fibre remodelling.

With heavy forces, rupture of blood vessels and severing of the periodontal ligament fibres are likely but both are restored with the remodelling processes.
