ABSTRACT
Objective: The Objective Of This Study Was To Compare The Platform- Switched And Non-platform Switched Implants For Complete Implant Assisted Mandibular Overdenture In Controlled Type II Diabetic Patients Clinically And Radiographically.

Materials and Methods: Ten Controlled Type II Diabetic Male Patients Were Selected For This Study. Split Mouth Study Design Was Used In This Study Where, Group I Represented The Right Side Of The Patients� Mandibular Interforamenal Region Restored With Platform-switched Implant And Group II Represented The Left Side Of The Patients� Mandibular Interforamenal Region Restored With Non-platform Implants. The Patients Received Complete Mandibular Assisted Overdenture With O-ring Attachment. Clinical And Radiographic Evaluations Were Carried Out For Every Patient At Regular Recall Visits At The Time Of Insertion, 6, 12 And 18 Months. At The End Of The Study, All Implants Of Both Groups Were Successfully Osseointegrated. The Data Of This Study Were Collected, Tabulated And Statistically Analyzed By IBM-SPSS Statistics Software (Independent T-test Samples). There Were Insignificant Differences Between Both Groups Regarding Plaque Index, Bleeding Index, Pocket Depth And Stability Of The Implants. Radiographically, There Were Significant Differences In The Mandibular Bone Density At The Bone Implant Interface And Marginal Bone Loss Between Both Groups. Group I Implants Represented Less Marginal Bone Loss And Higher Bone Density Than Group II Implants. Conclusion: Platform-Switched Dental Implant Is The Implant Of Choice Particularly In Controlled Type II Diabetic Patients To Control Marginal Bone Loss Around Implants.
