Localized Piezoelectric Alveolar Decortication for Orthodontic Treatment in Adults: A Randomized Controlled Trial

Area of Science:

• Dentistry
• Orthodontics
• Periodontology

Background:

• Piezocision is a minimally invasive corticotomy technique used in orthodontics.
• Conventional orthodontics can involve lengthy treatment times.

Purpose of the Study:

• To evaluate the benefits and clinical outcomes of piezocision in orthodontic treatment.
• To compare treatment acceleration and patient-centered outcomes between piezocision and conventional orthodontics.

Main Methods:

• A randomized controlled trial involving 24 adult patients with mild overcrowding.
• Patients were allocated to either conventional orthodontics or piezocision-assisted orthodontics.
• Periodontal parameters and patient-reported outcomes were assessed.

Main Results:

• Piezocision reduced overall orthodontic treatment time by 43%.
• No significant changes in periodontal parameters (recession, pocket depth, plaque, bleeding) were observed.
• Patient satisfaction was significantly higher in the piezocision group.

Conclusions:

• Piezocision effectively accelerates orthodontic tooth movement with improved patient satisfaction.
• No negative periodontal effects or increased root resorption were noted.
• Potential for scarring may limit its application in patients with high smile lines.
