摘要: Background: Chemical and physical properties of an implant surface have a major influence on the structure peri-implant bone thus may clinical performance implant. This study aims to evaluate microstructure around implants with without added nanometer-sized calcium phosphate particles.Methods: An dual acid-etched (control) CaP nanoparticles (test) were placed in posterior maxilla 15 patients. Bone was evaluated for osteocyte density (OD), vessel volume (BVVD), mineral (BMD).Results: BVVD 1.806 ± 0.05 test 1.533 0.10 control (P 0.05). OD 575.6 63.7 mm2 471.2 61.9 imp...
