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 control 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.
