| Purpose: To evaluate the peri-implant marginal bone loss and oral health-related quality of life in patients receiving mini-implant-retained mandibular overdentures with different occlusal schemes. Materials and methods: Twenty-one completely edentulous patients were selected. All patients received complete dentures before the surgical procedures, The patients were randomly divided into three groups according to the occlusal scheme. Group I: complete dentures with lingualized occlusal scheme, Group II : complete dentures with Monoplane occlusal scheme, Group III : complete dentures with bilateral balanced occlusal scheme. Four mini implants were inserted and loaded in each patient in mandible intraforminally. The peri-implant marginal bone loss and oral health-related Quality of Life were evaluated at implant loading (baseline or zero month), six and twelve months after implant loading . Results: No significant difference in the peri-implant marginal bone loss was found between Group I, II and III in the 0-6 follow-up period, while at the 0-12 follow-up period significant difference was found. No significant difference was obtained between total OHIP-EDENT scores in the three groups at baseline and 6-months follow up visits, while at the 12-months follow up visit, significant difference was found . Conclusion: Within the limitations of this study, it can be concluded that in mini-implant retained mandibular overdentures, lingualized and monoplane occlusal schemes may provide better results in the peri-implant marginal bone loss aspect compared to bilateral balanced occlusal scheme. Furthermore, in patients’ oral health-related Quality of Life aspect, lingualized occlusal scheme may be superior to monoplane and bilateral balanced occlusal schemes. | ||||
