The most important factor in the implant is the primary stability of implant mostly in the low-density bone which affects the integrity of the implant. Previously many different techniques have been discussed to increase the stability of implant but the promising result has not achieved. Recently Sala Huwais in 2013 introduces the novel implant site preparation technique termed osseodensification. A specially designed bur known as densah bur used in this technique which creates compaction of an auto graft layer at the periphery and apex of the implant rotating in a clockwise and counter-clockwise direction. This review article aims to emphasize osseodensification drilling concept and its various evidence-based study is discussed which proves that osseodensification concept is valid as biomechanical and histological and gives higher insertion torque value which increases the primary stability of the implant.
