Assessment of Piezoelectric Periodontal Surgery Effects on Orthodontic Treatment: a Prospective Pilot Study

EXPECTED RESULTS Orthodontic treatment accelerated by piézocicison will be completed within one year and will be 50% faster than a traditional treatment. The ratio benefit / risk of performing the piezocision will be acceptable for the patient and the orthodontist. We expect the following results: low pain, and absence of dental and periodontal deleterious effect (no root resorption, no tooth vitality loss and no bone loss). The same cohort can be used in future studies to assess the long term stability of the treatment.
