Osseodensification Regular and Short Burs Densah Type
Description of Osseodensification Burs Kit :
including Short Burs is the best value for your practice if you use multiple implant systems. These Densah type burs use external irrigation and are compatible with all available sized implants upto 6.0 leaving you with the flexibility to do more with less. The flute design allows the bur to work in 2 modes:
- Cutting Mode (Clockwise rotation) at 800-1500 RPM.
- Densifying Mode (Counter-Clockwise rotation) at 800-1500 RPM.
Features :
Osseodensification Burs kit technology is based on a novel biomechanical bone preparation technique called “osseodensification.” Unlike traditional dental drilling techniques, osseodensification does not excavate bone tissue. Rather, bone tissue is simultaneously compacted and auto-grafted in outwardly expanding directions
from the osteotomy. When a Osseodensification Bur is rotated at high speed in a reversed, non-cutting direction with steady external irrigation, a strong and dense layer of bone tissue is formed along the walls and base of the osteotomy. Dense compacted bone tissue produces stronger purchase for your favorite dental implant and may facilitate faster healing.
Biomechanical1 as well as histologica validation studies of the osseodensification and the procedure utilizing the Osseodensification Densah Burs technology concluded that, in porcine tibia and Sheep Illiac Crest, osseodensification may facilitate bone expansion, increase implant stability and create a densification layer around the preparation site by compacting and autografting bone particles along the entire depth of the osteotomy.
Advantages :
Regular twist drills or straight fluted drills have 2-4 lands to guide them through the osteotomy. Osseodensification Burs are designed with 4 or more lands, which precisely guide them through bone. More lands means less potential chatter. During osseodensification, Osseodensification Burs produce a controlled bone plastic deformation, which allows the expansion of a cylindrical osteotomy without excavating any bone tissue.
Modes:
Osseodensification Burs progressively increase in diameter throughout the surgical procedure and are designed to be used with standard surgical engines, to preserve and compact bone
(800-1500 rpm) in a counter clockwise direction (Densifying Mode), and to precisely cut bone if needed (800-1500 rpm) in a clockwise direction (Cutting Mode).
Motion:
The Osseodensification Burs are always to be used with copious irrigation in a Bouncing-Pumping motion (vertical pressure to advance the drill into the osteotomy, then a minor pull out for pressure relief, then advance with vertical pressure again and so on in an in/out fashion). The duration and number of bouncing-pumping episodes (in/out) are usually dictated by bone density and desired length.

Osseodensification Densah Burs Marking
Osseodensification Burs are externally irrigated and designed to be used at drill speeds of 800-1500 rpm. They are marked with laser markings1 from 3-20 mm depth. Osseodensification Burs have a tapered geometry; catalog number is a reflection of their minor and major diameter dimension. E.g., Osseodensification Bur VT3848 has a (minor-diameter) of 3.8 mm and a coronal (major-diameter) of 4.8 mm at 11.5 mm laser mark with an average-diameter of (4.3 mm) at the 8 mm laser mark which becomes the crestal diameter for short implants length ≤ 8 mm.
Drilling Depth
Measure the drilling depth of the Osseodensification Bur from the widest
part of its tip to the indication line. Regardless of the Osseodensification Bur
diameter, the maximum additional tip depth is 1.0 mm.
Short Osseodensification Bur Marking
Short Osseodensification Burs are externally irrigated and designed to be used at drill speeds of 800-1500 rpm. They are marked with laser markings (1) from 3-15 mm depth. Eg., Short Osseodensification Bur V3848-S has a (minor-diameter) of 3.8 mm and a coronal (major-diameter) of 4.8 mm at the 10 mm laser mark.
NOTE: Cutting and Densifying must be done under constant water irrigation. A pumping motion is required to prevent over heating. Surgical drills and burs should be replaced every 12-20 osteotomies2 or sooner when they are dulled or worn.
Drilling Depth
Measure the drilling depth of the Short Osseodensification Bur from the widest
part of its tip to the indication line. Regardless of the Short Densah® Bur diameter, the maximum additional tip depth is 1.0 mm.
