简要总结
different possible osseodensification techniques used to improve bone density around dental implants, using either ] osseodensifying drills, reverse drilling of conventional drills, and rotary expanders.
详细描述
the study include 3 groups with different implant drilling protocols; group 1 where osseodensifying burs are used, group 2 where conventional drills with reverse motion are used, group 3 where rotary expanders are used
