Effect of Different Types of Occlusion on the Supporting Structures of Mandibular Overdenture Retained by Two Splinted Mini-Implants

Objective: To evaluate and compare the effect of lingualized occlusion and monoplane occlusion on theperi-implant bone level of mandibular overdenture retained by two splinted mini-implants using Cone BeamComputed Tomography(CBCT).Methodology: Fourteen completely edentulous patients were divided randomly into two equal groups: GroupI received splinted Mini-implant retaining mandibular overdentures with their occlusal scheme set accordingto the lingualized concept.Group II received splinted Mini-implant retaining mandibular overdentures withtheir occlusal scheme set according to the monoplane concept. The peri-implant marginal bone loss wasevaluated at zero, six and twelve months from the time of loading using CBCT.Findings: The crestal bone loss around mini-implants in Monoplane group is higher than Lingualized groupwith no significant difference.Conclusion: In case of splinted mini-implants retaining mandibular overdenture,type of occlusion has noeffect on the supporting structures.
