简要总结
Patients with long span, narrow edentulous ridge in the posterior mandible underwent piezotomed ridge splitting and osseodensification with simultaneous implant placement.
详细描述
This study is a single arm clinical trial. Patients of both genders, who are indicated for ridge splitting, were recruited from the outpatient clinic, Faculty of dentistry, Alexandria University.
The PICO question: "What is the effect of piezotomed ridge splitting and osseodensification on implant placement in narrow posterior mandibular ridges?"
Ethical approval for the study was obtained from the regional Ethical Review Board of the Faculty of Dentistry. All patients were informed about the procedure details, and each participant signed a written consent.
Ridge expansion was accomplished by piezotomed ridge splitting and osseodensification. Simultaneous implant placement was done in the same procedure.
Implant stability was assessed. Also, bone width gained and bone density were measured around the dental implants using cone beam computed tomography.

结局指标
主要结局
The score of primary implant stability
时间窗: immediately at time of implant insertion
- Primary stability of the implants is measured using: * insertion torque and * resonance frequency analysis by Osstell ISQ device (Osstell ISQ, W\&H, Sweden)
次要结局
- The width of bone gained(3 months postoperative)
- The mean bone density around dental implants(3 months postoperative)
