ABSTRACT
Nowadays Mini-implant Overdenture Is Widely Used As A Substitution For The Conventional Two-implant Overdenture. The Thermoplastic Denture Bases Are Excellent Alternatives To Conventionally Used Acrylic Denture Bases, Therefore, The Purpose Of The Article Is To Evaluate Clinically The Patient Satisfaction, The Pocket Depth And Gingival Index Of The Supporting Structures Around Mini Implant Retained Over Denture Utilizing Three Different Denture Base Materials. Subjects And Methods: Twenty-four Healthy Completely Edentulous Male Patients Were Selected From The Outpatient Clinic, Patients Were Divided Randomly Into Three Equal Groups (eight Patients Each) According To The Denture Base Material: Group I: Patients Rehabilitated With Four Mini Dental Implants Retained Over Denture With Conventional Acrylic Denture Base. Group II: Patients Rehabilitated With Four Mini Dental Implants Retained Over Denture With Hard Thermoplastic Denture Base Polyan IC (PMMA) Group III: Patients Rehabilitated With Four Mini Dental Implants Retained Over Denture With Semi Flexible Thermoplastic Denture Base (bre Flex 2nd Edition). The Clinical Evaluation Was Measured In From Of Pocket Depth, Gingival Index And Patient Satisfaction After Immediate Loading Of The Dentures (baseline), 3, 6 And 12 Months.

Results: No Implant Failure Was Detected. The Mini Implants Were Assessed Clinically Throughout The Study Period By Observing The Absence Of Any Signs Of Inflammation Or Infection. The Pocket Depth And Gingival Index Values Were Significantly Higher In The Group Of Semi Flexible Thermoplastic Denture Bases While Patient Satisfaction Values Were Better In The Acrylic Group. Conclusion: Under The Limitations Of This Study, We Can Conclude That The Conventional Acrylic And Hard Thermoplastic Resins Are Better To Some Extent Than Semi Flexible Thermoplastic Resins Regarding The Peri-implant Gingival Measurements And Patient Satisfaction.
