Osseo-integration continues to be the primary challenge that implantologists encounter. There are multiple factors that can lead to failed osseo-integration between the implant and surrounding bone; such factors include low bone density in the site of implantation, incorrect positioning, tissue damage or overloading. In the case of low bone density, the sinus lift and bone graft remain to be the optimal procedures to increase bone mass. But a new set of dental instruments and techniques from the Versah group might assist the dental world in improving current procedures for low bone density implant sites.
A recent study from the Biomaterial Clinical Research Association evaluated a new surgical technique for implant site preparation. The Italian group of researchers developed a technique that sought to enhance bone density, implant secondary stability, and ridge width.
Two sheep were used as the test subjects and the results of the in-vivo evaluation were observed. In each sheep, the edge of the iliac crests were inserted with the dental instruments Dynamix implants. The left side (control group) of the crests were inserted with 3.8 x 10-mm implants with conventional drilling. The right side (test group) of the crests were inserted with 5 x 10-mm implants using Versah osseo-densification procedure. This procedure uses Densah Burs that are rotated in reverse at 800-1500 rpms. When this method is coupled with irrigation, bone is densified hydro-dynamically through osseo-densification.
The observations were recorded after two months of healing. The results showed that there were no implant failures in either test group. The test group demonstrated a significant increase in ridge width and bone volume percentage (%BV). The researchers noted that %BV was approximately 30% higher in the test group. The test group also recorded improved removal torque values and micro-motion under lateral forces.
The osseo-densification technique demonstrated strong evidence in improving the implant preparation site. By increasing %BV and around the implants, the method showed to play a role in improving implant stability and reduce micro-motion. Further research will be conducted to provide additionally confirmation on the success rate of Versah osseo-densification.
