Comparison of Zirconium and Tiantium Abutments With Peri-implant Mucositis: A Study in Dogs
Objectives: The purpose of this study was to investigate IL-1β and TNF-α in PICF around zirconium and titanium healing abutments with or without peri-implant mucositis in dogs.
Methods: The third and fourth premolars and the first molar of three beagle dogs were extracted. Eight implants were inserted into each dog after healing. Two months later, the zirconium and titanium healing abutments were connected and PICF were collected as the initial time. Then ligaments were placed around the neck of healing abutments to induce peri-implant mucositis. Four weeks later, PICF were collected again. The volume of PICF and IL-1β and TNF-α in PICF of zirconium and titanium healing abutments with or without peri-implant mucositis were analyzed.
Results: The volumes of PICF around zirconium healing abutments and titanium healing abutments in peri-implant mucositis groups were higher than control groups. The volume of PICF around zirconia healing abutments in peri-implant mucositis group was higher than that of titanium healing abutments. The levels of IL-1β and TNF-α in PICF of around zirconia healing abutments were lower than those of titanium healing abutments in peri-implant mucositis group and control group, while the levels of IL-1β and TNF-α in peri-implant mucositis groups were higher than control groups. However, there were no statistical differences.
Conclusions: Zirconium oxide may be promising as dental implant abutment material.
