In this case with lowbone density, the design of the implant and drills combined with sub-instrumentation played a differential role in achieving high primary stability. And to optimize primary stability, it is interesting to use a cutting implant to cut and to stabilize in the cortical nasal cavity and a compacting body to optimize the quality of the bone throughout the implant. Features we find in Helix GM ® . What were the other treatment options? “We could make the solution with overdentures, but it would be semi-fixed, which would not offer the same comfort and quality of treatment as the fixed solution. Added the possibility to install a fixed prosthesis on the day of surgery. There was any challenge during the treatment? The lack of bone in the posterior area was solved by tilting the implants, using the NeoArch ® concept. Remaining low density bone, was solved with sub-instrumentation of the implants and bicortilization. TIPS In some cases with low quantity of bone in the posterior area, it is possible to avoid bone grafts by tilting the implants. In low density bone, it is possible to sub- instrument and fix the apex of the implant in the cortical nasal cavity to achieve greater primary stability. u
