Two-Stage Bone Expansion Technique Using Spear- Shaped Implants Associated with Overlapped Flap: A Case Report

Abstract

The conventional method of ridge expansion uses a mucoperiosteal flap elevation to allow bone corticotomy, which is followed by bone expansion performed with chisels and bone expanders. To facilitate corticotomy and avoid flap elevation, bone expansion can be performed in 2 stages. This case report presents a modified 2-stage bone expansion technique to achieve better implant stabilization and wound closure. This modified approach may be an efficient procedure for minimizing complications.
