Abstract
BackgroundThe purpose of this study was to evaluate the effect of nanoparticles (NPs) of a plant extract on implant osseointegration in vivo. NPs of the Cissus quadrangularis (CQ) extract were synthesized. Twenty Wistar rats were included in the study. The test group (n = 5) had NPs-incorporated, the control group (n = 5) had no incorporation of NPs, and the sham group (n = 5) did not have implants placed. The toxicity profile of NPs was carried out by biochemical analysis before and after the implant placement. The rate of integration was assessed using Cone Beam Computed Tomography (CBCT), Digital X-ray, histology, and scanning electron microscopy (SEM) at intervals of 2, 4, and 6 weeks. Statistical significance between the groups was determined by Analysis of Variance (ANOVA) (p < 0.05) and the differences were uncovered with post hoc Tukey’s test.ResultsRadiographs showed that the bone density around implants with NPs was considerably higher than those without NPs. The osteoid seam along the implant surface was found to be considerably higher in the test group. A noteworthy increase was observed in the bone formation around the implants in bone samples belonging to the test group. Comparing the values at different time intervals, the highest serum Alkaline phosphatase (ALP) activity was noted in the test group after six weeks and the lowest serum Acid phosphatase (ACP) activity was documented in the test group after 6 weeks.ConclusionThe test group samples exhibited an osseointegration rate of less than 2 weeks thus demonstrating CQ NPs to be a potent osteoinductive agent.Graphical abstract
