Objective: The purpose of this research to assess platform-switched implants viability for improvement of osseous and soft tissue response in implant-assisted mandibular overdentures in controlled diabetic patients type2 diabetes mellitus(T2DM) and non-diabetic patients(control group).

Material and methods: For this study, fourteen completely edentulous patients were included, in two equal groups; GroupI healthy non-diabetic patients and groupII patients diagnosed controlled T2DM. New complete dentures were constructed following conventional steps. For participants, two platform-switching implants were inserted in mandibular canine area following flapless technique guided by 3D printed surgical guide and applied immediate loading. Gingival index and pocket depth were measured at one week after implant placement,3,6and12months follow-up. While peri-implant marginal bone level was measured at loading time,6and12months follow-up. For diabetic patients, hemoglobinA1c test done every 3month for monitoring their medical condition. Data collected were statistically analyzed.

Results: Peri-implant bone loss of higher values was found in diabetic patients compared to non-diabetic patients with no statistical significance along the follow-up records. Gingival index and pocket depth showed no statistical significance along the study period with better value for non-diabetic patients compared to diabetic patients.

Conclusions: Within limitations of this study, it was revealed two platform-switching implants assisting mandibular overdenture is successful and predictable treatment option for type2 controlled diabetic patients as non-diabetic patients. Peri-implant bone loss was found in diabetic patients higher but insignificantly compared to non-diabetic patients during 1year follow-up period. Regarding clinical assessment, no significant difference in both groups with consideration continuous glycemic control and optimum oral hygiene measures.
