In a 64-years-old patient, the maxillary dental implants were removed due to peri-implant inflammation and replaced with a upper full denture. The patient was satisfied with this treatment.
Bacteriological investigation was carried out for the necks and bodies of the removed implants and the remaining natural teeth. In all the areas examfined, bacterial flora was predominated by Streptococcus. The ratios of Streptococcus isolated from the natural teeth, the necks of the implants and bodies of the implants were 52.5,39.7 and 23.0% respectively. The ratios of Staphylococcus isolated from the natural teeth, the necks of the implants and the bodies of the implants were 3.4, 13.8 and 19.7% respectively, demonstrating high ratios of Staphylococcus in the implants.
These results suggested that since Staphylococcus have a severely pathogenic and phlogogenic action,the degree of inflammation at the implant-support may be estimable to a certain degree from the degree of multiplication of these bacteria, this may be usefull in the prediction of the prognosis.
