Clinical Trial Summary

Patients with long span, narrow edentulous ridge in the posterior mandible underwent piezotomed ridge splitting and osseodensification with simultaneous implant placement.

Description:

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	The score of primary implant stability	- Primary stability of the implants is measured using: insertion torque and; resonance frequency analysis by Osstell ISQ device (Osstell ISQ, W&H, Sweden)	immediately at time of implant insertion
Secondary	The width of bone gained	Width of bone gained at the crest of the ridge is measured by cone beam computed tomography in mm	3 months postoperative
Secondary	The mean bone density around dental implants	The mean bone density around dental implants is measured by cone beam computed tomography in grey scale values	3 months postoperative
