A Novel Osseous Densification Approach in Implant Osteotomy Preparation to Increase Biomechanical Primary Stability, Bone Mineral Density, and Bone-to-Implant Contact

Abstract

This study confirmed the hypothesis that the osseous densification technique would increase primary stability, bone mineral density, and the percentage of bone at the implant surface compared with drilling. By preserving bulk bone, it is hypothesized that the healing process will be accelerated due to the bone matrix, cells, and biochemicals that are maintained in situ and autografted along the surface of the osteotomy site. The healing response requires further study in vivo.

Osseodensification for enhancement of spinal surgical hardware fixation

“…Moving further from previous failures in implant placement and stability, a new surgical method was studied in a sheep spine in the present study. This new technique, osseodensification, is performed via gradual compaction of bone tissue, forming the walls of the osteotomy through densification, essentially acting as an auto-graft to supplement implant fixation (Huwais and Meyer, 2016). In a hip model where low bone density is present, osseodensification drilling was determined to have superior primary stability as measured by insertion torque, and demonstrated no impairment to osseointegration when compared to regular drilling, irrespective of implant macrogeometry (Lahens et al, 2016).…”

“…Recently, a drilling approach termed osseodensification has been introduced for placement of endosteal fixtures (Huwais and Meyer, 2016). Osseodensification is performed in an attempt to develop a condensed autograft surrounding the implant, making it valuable in clinical settings where there is an anatomic paucity of bone (Lahens et al, 2016).…”

“…Osseodensification is performed in an attempt to develop a condensed autograft surrounding the implant, making it valuable in clinical settings where there is an anatomic paucity of bone (Lahens et al, 2016). Unlike traditional drilling protocols (which we refer to as subtractive drilling), osseodensification increases primary stability due to densification of the drilled osteotomy site walls centrifugally by means of non-subtractive drilling (Huwais and Meyer, 2016). The rationale is that compacted, autologous bone immediately in contact with an endosteal device will not only have higher degrees of primary stability due to physical interlocking between the bone and the device, but also facilitate osseointegration due to osteoblasts nucleating on instrumented bone in close proximity to the implant (Lahens et al, 2016).…”

Increasing the stability of dental implants: The concept of osseodensification

“…However, primary stability of the implant is greatly affected as bone is removed from the implantation bed 100 . Osseodensifying Furthermore it has been reported that insertion torque is directly related to the initial bone-to-implant contact percentage at the time of implant placement 25,71 .…”

Osseointegration- A Review

“…Despite of some relevance for biomaterials research, this approach has not been without drawbacks. Improvements of the surgical technique seem to be a reliable way of increasing [4] It is carried out using specially designed burs to increase bone density as they expand an osteotomy.…”
