To evaluate the presence of titanium particles in the peri-implant mucosa of unloaded single implants.
Materials and Methods
Forty participants with single unloaded implants were selected. They were divided equally into two groups: Group 1 with mild and Group 2 with moderate-to-severe peri-implant mucositis. Cytologic smears of peri-implant mucosa were obtained using cytobrush during second-stage surgery.
Study states that 60% of participants of Group 2 were positive for titanium particles in peri-implant cytology.
This study concludes that the titanium particles might be the initiators of the inflammation around implant.
