Laser bio-stimulation may enhance soft and hard peri implant tissues after 1-stage ridge splitting in narrow mandibular ridges: Study

The Mann-Whitney test was used to test the difference between the 2 different groups at each evaluation time (α=.05). The Friedman test was used, followed by the Wilcoxon signed rank test, to test the change over time in the same group, and the Bonferroni adjusted significance level was used for multiple comparisons. Results: Some clinical and radiographic parameters significantly increased with time in both groups (P<.001). Significant differences between the 2 groups were revealed in bleeding scores at 3 months (P=.006) and 6 months (P=.018). Also, significant differences between the 2 groups were observed in gingival scores at 3 months (P=.002), 6 months (P=.015), and 12 months (P=.019) after overdenture insertion in favor of the laser group. Peri-implant VBL was significantly higher in the non-laser group at 6 months (P=.015), and 12 months (P=.001). Within the limitations of this clinical study, respecting the small sample size and the short follow-up period, laser bio-stimulation after 1-stage ridge splitting in narrow mandibular ridges enhanced the soft and hard peri implant tissues when used with LOCATOR attachments and PEEK overdentures.
