Scalp-Split Technique: A Concept of Bone Splitting and Expansion for Thin Alveolar Ridges to Place Dental Implants.

Bone expansion is when the existing bone at the implant site is split and separated to create a gap to widen it. This article introduces a novel concept of bone expansion for the ultrathin alveolar ridges to place dental implants with zero wastage of existing natural bone in long-term edentulous arches. Instead of using twist drills and piezo surgery kits, the bone is split with a surgical scalpel blade to prevent natural bone wastage.
