Evaluation of Peri-implant soft tissue and Crestal bone level of nanometer scale surface coated (Nanotitetm) implants: A clinico-radiographic study

Aim and Objective: The objective of this controlled clinical trial was to clinically evaluate the peri-implant soft & hard tissues and to radiographically analyze the difference in crestal bone level both mesial and distal to the implant. Materials and methods: A total of ten sites from ten volunteers were selected for the placement of the implants and were subjected to presurgical evaluation and clinical and radiographic parameter assessment. Statistical analysis used: Mann-Whitey U test and Wilcoxon Signed Rank Test were used to find the significance of study parameters on continuous scale for the intragroup comparisons and the comparison between the mesial and distal bone levels. Results: At baseline, 6 and 9 months there was a statistically significant overall decrease in the mean gingival index score around implants. The mean plaque index, sulcus bleeding score and mean difference in the peri-implant probing depth (mm) around the implants was statistically not significant. The mean width of keratinized mucosa and the mean papilla fill index remained constant throughout the study. On comparison between the mesial and distal implant site there was more crestal bone loss on the mesial than on the distal aspect. Conclusion: Nanothin surface coating of calcium phosphate enhanced the biological response of bone to implant at the early implantation times, supporting opportunities for increased bone healing response in clinical practice.
