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.

ABSTRACT
Objective: The Aim Of The Present Study Was To Assess The Effect Of Using Three Different Voxel Sizes On The Accuracy Of Planmeca Promax 3D Mid CBCT Images In Detection Of Simulated External Root Resorption Defects In Mandibular Single Rooted Teeth.

Materials and Methods: Fifty Five Recently Extracted Human Mandibular Incisor Teeth Were Collected And Disinfected, Five Hundred Defects Were Prepared On Their Different Root Surfaces Simulating External Root Resorption Lesions, The Teeth Were Positioned Inside The Sockets Of A Dry Mandible And Were Imaged By The Planmeca Promax 3D Mid CBCT Scanner Using 0.4, 0.2 And 0.15 Voxel Sizes, The Images Were Evaluated Independently By Two Radiologists.

Results: The Results Of Both Observers Showed That CBCT High Resolution Protocol Has Higher Sensitivity And Accuracy Than Normal And Low Resolution Protocol, Moreover, The CBCT Low Resolution Protocol Showed The Least Sensitivity And Accuracy Among All Protocols. Additionally, According To Both Observers, There Was A High Statistically Significance Difference In The Detectability Of All Simulated Defects Using CBCT Low Resolution Protocol (voxel Size 0.4) And Both Normal (voxel Size 0.2) And High (voxel Size 0.15) Resolution Protocols (P <0.001 HS), While There Was No Statistical Significance Difference In Detectability Of The Defects Using CBCT Normal And High Resolution Protocols (P > 0.05 NS). Conclusion: Considering The Studied CBCT Scanner, The Normal And High Resolution Protocols (voxel Sizes 0.2 And 0.15 Respectively) Showed A Similar High Efficacy In Detection Of Simulated External Root Resorption Defects In Mandibular Single Rooted Teeth And Their Usefulness Was Superior To That Of The Low Resolution Protocol (voxel Size 0.4). However, According To The ALARA Principle, The Normal Resolution Protocol Should Be The Scan Of Choice As It Delivers Less Radiation Exposure To The Patient.
