| Outline of Final Research Achievements |
Purpose: Evaluation of the effect of cultured autogenous periosteal cells (CAPC) on sinus lift (SL). Materials and Methods: SL with autologous bone and PRP plus CAPC [CAPC(+)SL] was performed in 23 cases. Pieces of mandibular periosteum were cultured in M199 medium with 10% FBS for 6 weeks. As control, 16 cases received SL with autologous bone and PRP [CAPC(-)SL]. High-resolution 3D-CT was performed before, 4 months and 1 year after SL, and stratified data based on CT numbers corresponding to soft tissue, cancellous bone, and cortical bone were subject to analysis. Results: CAPC(+)SL revealed an increase in CT numbers corresponding to cancellous bone as well as a decrease in those to cortical bone. CT numbers corresponding to cancellous bone were increased in CAPC(+)SL while they were decreased in CAPC(-)SL. Implant insertion torque was significantly higher in CAPC(+)SL. Conclusion: By promoting bone anabolic activity, CAPC is expected to aid osseointegration in clinical applications.
