Evaluation of the Effects of Osteoperforation and Piezocorticision on Canine Retraction

Evaluation of the Effects of Osteoperforation and Piezocorticision on Canine Retraction: Randomized Controlled Clinical Trial.

The primary objective of this research is to compare the rate of canine retraction following the osteoperforation and piezocorticision procedures in cases of first premolar extractions. The secondary objectives are to compare the second order movement of the canine (tipping), the amount of root resorption associated with the procedures, the inflammation process by measuring the inflammatory markers in the gingival crevicular fluid, the loss of posterior anchorage by measures on the cone beam computed tomography (CBCT) 3-dimensional radiograph and on the casts and to evaluate the pain level and the impact on quality of life following each procedure using the questionnaire of the visual analogue scale (VAS) of pain.

Inclusion Criteria:

• Dental and/or skeletal Cl I and II requiring maxillary first premolar extraction.
• Young adults 16 years and older.
• Good overall health.
• Complete adult dentition.
• Cooperative.
• Acceptable hygiene.
• Absence of any periodontal disease (gingivitis, periodontitis).

Exclusion Criteria:

• Non-cooperative, fearful patients or patients with intellectual disability.
• Patients requiring the regular use of nonsteroidal anti-inflammatory drugs (NSAID).
• Use of antibiotics in the last 6 months.
• Previous or current use of bisphosphonates, corticosteroids or immunosuppressive drugs.
• Smokers.
• Patients suffering from uncontrolled systemic diseases (ex. diabetes type I and II).
• Presence of oral or maxillofacial malformations (ex. cleft palate) or dental pathologies (ex. ankylosis, abscess).
