Abstract: Presently, the replacing of missing tooth via dental implants has become a widespread treatment modality. Dental implants inserted at the posterior region of the maxilla exhibit the lowest success rates as the low density bone in this area often jeopardize rigid fixation of the implant. For long-lasting clinical outcome of implant therapy it is necessary to achieve primary implant stability osseointegration. Other factors, such as bone quality and quantity, surgical techniques are important for achieving primary stability. Maintaining sufficient bone density and bone bulk are also essential factors to achieve bone-to-implant contact for obtaining a biomechanically stable implant. Recently, a new technique is developed which enhances the bone density around dental implants known as Osseodensification (OD), that creates an autograft layer of condensed bone at the periphery of the implant bed by the aid of specially designed burs rotating in a clockwise and anti-clockwise direction. This relatively new concept with universally compatible drills has been proposed to help in better osteotomy preparation, bone densification, and indirect sinus lift and also achieve bone expansion at different sites of varying bone densities. This procedure has also shown improvement in achieving better implant primary stability and better osteotomy than conventional implant drills. Numerous studies have been performed on this new surgical technique. The purpose of this review article is to discuss in detail on OD procedure.
