简要总结
There were no discernible differences in clinical outcomes among immediate, early, and delayed implant placements in elderly patients. However, the early implant placement protocol with an IT range of 30-40 Ncm appeared to achieve superior outcomes. Early implant placement significantly enhanced implant stability in elderly patients. Implant placement protocols did not influence 1-year MBLCs in this population.
