Aim: Immediately placed implant is lucrative and offers several advantages. This study was done to find out any hard tissue changes around the implants in bucco-lingual direction before and after 6 months of implant placement. Materials and Methods: This study was done on 18 patients who has undergone extraction and immediate implant placement. Implant system used was Alpha-Bio®. Pre- operative test includes computed tomography (CT) scan of the jaw, OPG and IOPA were done to assess the quality and quantity of the bone, proximity with anatomical structures and dimention of the tooth to be replaced and facio-palatal/lingual width of bone at the crest, 3 mm apical to the crest and 6 mm apical to the crest was calculated. Second stage surgery was carried out after 4 to 6 months depending upon the quality of the bone. Results: Statistical analysis was done on SPSS ver 15 software. The results were tested using Normality tests (Kolmogorov-smirnov & shapiro-wilk). The mean value bucco-lingual width, at the crest was 5.62±0.87 mm before implant placement and 5.35±0.78 after 6 months, 3 mm apical to the crest was 9.08±1.25 and after 6 months it was 8.87±1.21 and 6mm apical to the crest was 10.81±1.61 and after 6 months 10.55±1.64mm. Results from this present study showed statistically significant bone loss in bucco -lingual/palatal direction. Conclusion: We can say that immediate implant placement is a safe and predictable option, and bone remodelling bound to occur after implant placement but the facio-palatal/lingual changes are clinically not significant.
