| What Is Densah ® and Versah ® LLC?|| |
Densah ® Burs were created by Versah ® LLC which was founded by Dr. Salah Huwais in 2014. He created Versah ® to be able to provide improved and unique way of preparing osteotomies for implant placement. Conventional osteotomy preparation involves excavating bone using drills, contrary to what Dr. Huwais wanted to change. His aim was to preserve the healthy bone and make space rather than to remove bone. This led to the development of the term “Osseodensification (OD)” and this is achieved by the proprietary instruments developed by Dr. Huwais called “The Densah Technology.”
| Plasticity of Bone|| |
Bone is a unique formulation of proteins and mineral structure that form together contradictory properties. It is stiff yet flexible and light yet strong. Bone is flexible enough to absorb energy and change shape without failing. It widens in compression and lengthens with tension. Bone is capable of undergoing plastic deformation.
| Osseodensification|| |
OD is a novel biomechanical site preparation technique. It produces low plastic deformation due to its nonextraction site preparation method which preserves bone to enhance host response.
It utilizes a multi-fluted densifying bur technology that creates and expands a pilot hole without excavating significant amounts of bone tissue through a unique, highly controllable, fast, and efficient procedure with minimal heat elevation. The taper design allows the surgeon to modulate pressure and irrigation. It is rotated at 800–15,000 rpm in counterclockwise in noncutting direction (densifying mode) and is a downward surgical pressure coupled with steady irrigation. This creates a gentle compression wave inside the osteotomy that works with the fluting to generate a densified layer through compaction and autografting the surrounding bone, while plastically expanding the bony ridge at the same time.
| Advantages of Osseodensification|| |
- Increase in bone mineral density around periphery and bottom of the OD holes
- Autografting of bony particles, creating a smoother OD hole
- Increased bone–implant contact and primary stability
- Preserving bone bulk and allowing for predictable ridge expansion, especially at coronal level.
The above four points are more important due to the immediate loading and early loading protocols being implemented these days. The result is an expanded osteotomy with preserved and condensed bone tissue that maintains alveolar ridge integrity and allows implant placement with enhanced stability.
Higher insertion torque values due to densification result in reduced micromotion and more predictable outcomes.
| Conclusion|| |
With advancement in dental material science and instruments, implant dentistry is an ever-changing and evolving science. It is hence imperative for every clinician to keep abreast with the advances and employ them for further advantage of their patients.
One such technology is Densah ®, although long-term clinical trials and randomized controlled studies are warranted. However, keeping in mind the bone physiology, it is here to stay.
