Peri-implant tissue response to three implants engaging retained roots: a histologic report in the pig mandible

This preclinical report describes the histological response to three implants in contact with non-infected retained roots. In two specimens with partial root contact, bone was present at the interface and osseointegration was observed. In all three specimens, newly formed osteodentin was present at the implant interface, with evidence of early modeling and remodeling. Further controlled investigations are required to confirm these observations and to assess their reproducibility and broader biological relevance.
