Histologic Assessment of Peri-implant Tissues Around Endosseous Dental Implants Placed Along with Intentionally Retained Root Fragment in Animal Models: A Systematic Review.

Limited data and short-term preclinical evidence showed optimal peri-implant histologic findings of endosseous dental implants placed along with intentionally retained root fragments. However, further preclinical histologic evaluation with homogenous populations and long-term controlled clinical studies are needed to substantiate its applicability in clinical situations.
