Background: The present study was conducted to clinically evaluate the periodontal parameters of osseointegrated immediate and delayed dental implants and to radiographically evaluate the difference in the crestal bone height after immediate and delayed placement of dental implant. Materials & Methods: The present study comprised of thirty implant sites, in patients age group of 18 to 65 years. The patients were randomly allocated to the immediate (Im) group (n-15) or the delayed (De) group (n-15). Periodontal assessment was done using plaque index, gingival index, probing depth and width of keratinized gingiva. Radio-Visual Graphs (RVG) with and without grid; Orthopantamogram (OPG) and intra oral peri apical radiographs (IOPAR) were taken. The periodontal status was evaluated at baseline (1st month), 3rd and 6th months for both groups. Results: The mean difference in plaque score from baseline to 3 months in group I was 0.09, in group II was 0.06, baseline to 6 months in group I was 0.07 and in group II was 0.00, 3 months to 6 months was 0.02 in group I and 0.06 in group II. Intergroup comparison was non- significant (P> 0.05). A statistically non- significant difference in mean value of gingival index at baseline (p value=0.57), 3month (p value=0.74), 6 months (p value=0.62) between Group I and Group II. A statistically non- significant difference in mean value of probing depth at baseline (p value=0.34), 3month (p value=0.62), 6 months (p value=0.36) between Group I and Group II. A statistically non- significant difference in mean value of width of keratinized gingiva at baseline (p value=0.32), 3month (P-0.61), 6 months (P-0.72) between Group I and Group II. A statistically highly significant difference in mean value of bone level on mesial side at baseline (p value=<0.001), 3month (P<0.001), 6 months (P<0.001) between Group I and Group II. A statistically highly significant difference in mean value of bone level at baseline (p value=<0.001), 3month (P<0.001), 6 months (P<0.001) between group I and group II. Conclusion: There was significant crestal bone loss in Group II (Delayed implantation) at both mesial and distal surface during 3rd to 6th month’s observation period. Also a continuous bone resorption was observed over the time in the both groups. Key words: Delayed implant, Probing index, gingival index
