Peri-implant Inflammation Defined by the Implant–Abutment Interface
Abstract: An interface of implant-abutment at the alveolar bone crest is allied with sustained peri-implant inflammation; though, whether extent of inflammation is correspondingly reliant on interface position remains unknown. This study compared the distribution and density of inflammatory cells surrounding implants with a supracrestal, crestal, or subcrestal implant-abutment interface. All implants established a parallel pattern of peri-implant inflammation: neutrophilic polymorphonuclear leukocytes (neutrophils) extremely collected at or proximately coronal to the interface. …
