Effect of Different Types of Occlusion on the Supporting Structures of Mandibular Overdenture Retained by Two Splinted Mini-Implants
Keywords:Mandibular Overdenture - Mini-Implants-Occlusion.
Objective: To evaluate and compare the effect of lingualized occlusion and monoplane occlusion on the
peri-implant bone level of mandibular overdenture retained by two splinted mini-implants using Cone Beam
Methodology: Fourteen completely edentulous patients were divided randomly into two equal groups: Group
I received splinted Mini-implant retaining mandibular overdentures with their occlusal scheme set according
to the lingualized concept.Group II received splinted Mini-implant retaining mandibular overdentures with
their occlusal scheme set according to the monoplane concept. The peri-implant marginal bone loss was
evaluated 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 group
with no significant difference.
Conclusion: In case of splinted mini-implants retaining mandibular overdenture,type of occlusion has no
effect on the supporting structures.
