Implant stability is a prerequisite for successful implant osseointegration. Over the years, implant site preparation has been refined taking into consideration the fact that, the bone is a viable tissue. Even minor alterations in the steps of osteotomy like overheating, increased pressure etc. could lead to failure in osseointegration. This could be due to an alteration in the microvascular dynamics. Implant site osteotomies have been prepared using conventional drills since several decades. These drills are designed so as to excavate the native bone to create room for the implant to be placed. Contrary to that, a new technique is introduced which instead of excavating the bone tissue compacts and autografts the bone in an outwardly expanding directions from the osteotomy. This novel approach termed osseodensification, aids to preserve the bony bulk, increase primary stability through densification of the osteotomy walls, hastens the healing and facilitates ridge expansion. This narrative review focuses on the new bone drilling concept, namely osseodensification and its advantages over the standard subtractive drilling techniques. |
