Purpose: This study was done to compare the outcome of implants placed immediately in partially edentulous periodontally compromised to periodontally healthy patients clinically and radiographically. Material and methods: Twenty immediately placed implants were followed up one year after loading clinically and radiographically. Patients were divided into 2 groups: 10 implants in group H (healthy, n=9) and 10 implants in group PD (moderate to severe chronic periodontitis, n=7). Clinical (modified bleeding index mBI, modified plaque index mPI, probing pocket depth PPD and degree of mobility using Periotest device) and radiographic parameters (Bone implant contact ratio BICR and vertical bone resorption) were assessed. Results: There were no significant differences in implant success rate between the 2 groups. Since the time of loading till the end of follow up period all implants were immobile, there was no pain or suppuration around the implants and there were no evidence of peri-implant radiolucency in the x-rays. Through all periods; there was no statistically significant difference between the two groups in the mPI or PPD, at any time point. At loading and 3 months post-loading; PD group showed statistically significantly higher mean mBI than healthy group. PD group showed statistically significantly lower mean PTVs (more stability) at time of loading (-1±2.1) and at 3 months PL (-1 ±1.8) than the H group at loading (0.5±0.7) and 3 ms PL (0.6±2) where P was 0.022 and 0.031for L and 3 ms PL respectively. Regarding the radiographic measures, there were no statistically significant differences between the two groups in the BICR and the VBL at any time point, through all the follow up periods P value ≤ 0.05. Conclusion: Immediate implants may be successful treatment modality in partially edentulous patients suffering from moderate to severe chronic periodontitis, provided that careful debridement of the extraction sockets is done and a good maintenance protocol is followed.
