About

This study was designed to investigate the use of minimally invasive Piezo knife to harvest vascularized interceptal bone pedicle in treating intrabony defects.

Full description

Sixteen non-smoking patients with severe chronic periodontitis participated in this prospective, randomized clinical study. Patients were randomly assigned into one of a 2 groups (8 patients each): bone substitute grafting of the intrabony defect, control group (Gr1), intrabony defect osseous wall swaging (OWS) combined xenograft (Gr2). In both groups root surfaces where treated with a neutral 24% EDTA gel and saline irrigation. Clinical and radiographic measurements were reassessed at 6 months after surgery.

Enrollment: 16 patients

Ages: 25 to 60 years old

Volunteers: No Healthy Volunteers
