Piezocision-assisted Orthodontic Treatment Combined With Alveolar Bone Regeneration
Piezocision-assisted Orthodontic Treatment Combined With Alveolar Bone Regeneration
This study was designed to enroll a series of 10 consecutive patients who met the inclusion
 criteria. Patients were treated in the Department of Orthodontics and Dento-Facial
 Orthodopedics of the University of Liège. Two senior's orthodontists and two senior's
 periodontists were involved in the orthodontic treatment and in the surgical procedures
 respectively. All clinical, radiographic and periodontal measurements and all orthodontic
 parameters were performed at baseline and after the orthodontic treatments. Tree examiners
 collected the overall data.
Inclusion criteria:

 -  Patients requiring at least mandible orthodontic treatment (both arches)

 -  Patient presenting alveolar bone thickness < XX mm

 -  Adult patients with completed growth based on the Cervical Vertebral Maturation Method
 (CVM) as described by Baccetti et al. (Baccetti et al. 2002)

 -  Minimal to moderate mandibular anterior crowding at baseline (irregularity index≤6)
 (Little 1975)

 -  American Society of Anesthesiology I or II (I = Normal healthy patient; II = Patients
 with mild systemic disease)

 -  Adequate dento-oral health (i.e., the absence of periodontal diseases, peri-apical
 infection, or untreated caries).

 Exclusion criteria were as follows:

 -  Controlled periodontitis with a loss of alveolar support > 10%

 -  Gingival recession > 2 mm

 -  Smokers

 -  Altered bone metabolism (e.g., due to anti-resorptive drug, steroid or
 immunosuppressant use)

 -  Mental or motor disabilities

 -  Pregnancy
