Aims:
The aims of the study were to assess the technique with-flap and flapless implant placement and to compare crestal bone heights around the implant in flapless and conventional flap technique using digital radiovisiograph, in 3 and 6 months after the surgery.
Materials And Methods:
A total of 20 implants were placed by flap and flapless implant technique; each patient received two implants, except for two patients who received four implants. A radiovisiograph was taken at implant placement, as well as 3- and 6-month intervals. Crestal bone level was compared between flapless and flap during these intervals and compared between intervals for each group.
Results:
On evaluating the distribution, it was found to be asymmetric and hence lacked normality (K-S = 0.382; p <0.001). On mesial side, bone loss values in group I ranged from 0.40 to 1.10 units with a mean value of 0.71 and a standard deviation of 0.26 units. The median value was 0.70. On evaluating the data for normality, it was found to be symmetric and normal (K-S = 0.166; p = 0.200).
Conclusion:
This study concluded that there are not any significant differences in the crestal bone with both flap and flapless techniques. Comparatively, the flapless approach showed a lesser crestal bone height reduction, which was statistically significant.
Clinical Significance:
Implant dentistry is nonetheless behind when advances are concerned, we have seen the inclination toward minimal invasive implant techniques to yield better esthetic as well as improved results, thus taking care of patients' discomfort.
