OSSEODENSIFICATION USING THE DENSAH® BUR SYSTEM (VERSAH®) IN IMPLANT DENTISTRY: A NARRATIVE LITERATURE REVIEW

Abstract

The predictability of treatments with osseointegrated implants is directly related to the achievement of adequate primary stability, particularly in regions with low bone density. In this context, the osseodensification technique emerged as an alternative to conventional implant site preparation protocols, proposing the preservation and compaction of bone tissue during osteotomy through the use of Densah® burs, developed by Versah®. Unlike conventional burs, which promote bone tissue removal, osseodensification is based on controlled plastic deformation of bone, favoring trabecular compaction, autogenous bone particle translocation, and increased peri-implant bone density. These biomechanical changes have been associated with increased insertion torque, primary stability, and bone-to-implant contact, expanding clinical possibilities, particularly in areas with low bone density, such as the posterior maxilla. The aim of this narrative review was to gather and analyze the main scientific evidence regarding the use of the Densah® bur system, addressing its biological and biomechanical principles, clinical applications, advantages, limitations, and future perspectives in Implant Dentistry. For the development of this review, indexed scientific articles and classic studies investigating the osseodensification technique were consulted, with emphasis on experimental research, clinical studies, and literature reviews. The available evidence indicates that this technique represents a promising alternative for optimizing implant site preparation and promoting greater primary stability, particularly in low-density bone. However, prospective long-term clinical studies are still required to establish its indications, limitations, and clinical outcomes.
