Abstract

Implants serve as a foundation for prosthetic support. The purpose of this study was to evaluate and compare buccolingual and interproximal crestal bone changes after delayed and immediate platform switched, acid etched implant (SLA), without the use of graft or barrier membrane clinically as well as radio graphically.
Method: 14 implants were included in study and clinical and radiographic parameters i.e. buccolingual bone width (BLW), interproximal crestal bone height (CBH), Keratinized mucosa index score (KMI), Jemt papilla fill index score (PFI), probing attachment levels (PAL) were analyzed at baseline, 3 months and 6 months in immediate and delayed implant group (A,B).
Results: It was observed that mean change in BLW, CBH, PFI, PAL from baseline to 6 months for Group A and Group B was 3.42 ± 0.97 mm and 3.57 ± 0.97 mm, -0.30 ± 0.04 mm and -0.38 ± 0.06 mm, -1.42 ± 0.53 and -1.14 ± 0.37 and-0.78 ± 0.26 mm and -0.64 ± 0.37 mm respectively which was statistically significant in both the groups. There was no change in KMI scores observed at 3, 6 months of observation period in both the groups.
On comparing both the groups there was no significant difference between immediate and delayed implant placement with respect to all parameters recorded in the study.
Conclusion: There was observed significant differences when mean change from baseline to 6 months was compared but there existed a non-significant difference in crestal bone changes observed in immediate and delayed groups.
