The purpose of this research is to evaluate the possibility of implantation in chronic
periodontally infected sites The research sample comprised of 20 implants were placed in 6
patients from both sex , the sample were divided into 2 groups: the co
ntrol group, 10
implants were placed after waiting period of four months after the extraction and the test
group, 10 implants were immediately placed after extraction in areas of chronic
periodontally infected sites. Gingival index GI, marginal bone loss MBL, proping depth
PD, Implant survival, evaluated for both groups. The results of the present study showed
that the survival rate was 100% in control group and 80% in test group. There was no
statistical difference between the test and control regarding, GI, while there was statistical
difference between the test and control regarding MBL and PD during periods of follow
up.
