The Effect of Mini-Implants versus Conventional Implants Retained Mandibular Overdenture on Biting Forces

Aim: The purpose of this clinical investigation is to evaluate the biting force of patients restored with mandibular single over-dentures supported by Mandibular implants Two Conventional diameters versus four Mini Implants.
Materials and Methods: In this investigation, a total of twelve male patients with completely edentulous mandibles opposed by natural dentition were enrolled. Patients were distributed into two main groups;Group I received four inter-foraminal mandibular Mini-implants while Group li received two conventional implants with standard diameters in the inter-foraminal region as well. O-ring attachments were utilized in the lower denture to provide retention with the implants. The biting force of the participants was measured at insertion, 3 months and 6 months after insertion of the mandibular implant retained denture using a Load sensor. To evaluate significant changes within each group over time and to compare the two groups, one-way analysis of variance (ANOVA) and paired t-tests for pairwise comparison were utilized as analytical tests for all parameters. For all statistical tests, the significance threshold was established at 0.05.
Results: Statistical Analysis Comparison between the two groups revealed a significant difference between both groups where there were higher biting values in the Standard diameter Implant group than the Mini diameter implant group as P<0.0001*.
Conclusion: Within the limitation in this investigation, it can be determined that the standard diameter implants yielded more favourable biting forces in comparison with the mini-implant implant group supporting mandibular single implant retained over-denture.
