Quantity of Exudation from Peri－implant Sulcus of Bonefit^®

Abstract

The quantity of exudation from peri-implant sulcus was measured by Brill's method using Periotron Economy^® apparatus. Implants were 2 part-hollow screws of Bonefit^®. In some cases,Periotron values were very high (40～60) at first (after implantation), but dropped below 10 as time passed. In other cases values were always below 10. In non-functioning conditions of 11 cases over 90 days after implantation, the values of 9 cases were below 10 and the value of only one case was over 20. No inflammation of the peri-implant mucose was observed in the above cases. In functioning conditions of 17 cases, the values were below 10 in 11 cases and over 20 in 2 cases respectively. Thus, Periotron values of most cases were below 20 in functioning conditions as well as in non-functioning states.
