ABSTRACT
BACKGROUND: Several Patients Notice The Value Of Completely Edentulous Mandibular Ridge Therapy Through Complete Overdenture Implants To Be On The Far Side Their Money Scope, Mandibular Overdentures Reatined By One Implant Are Reported To Be More Leisurely And Function Better Than Conventional Complete Dentures. The Goal Of The Current Study Were To Analyze The Clinical Outcomes In Comparison Between Two Types Of Attachments, The Locator Attachment Versus The Equator Attachment Used With Immediately Loaded Single Implant Retained Mandibular Overdenture Opposing Conventional Complete Denture. METHODS: Ten Completely Edentulous Patients Were Managed With A Single Implant Inserted Into The Midline Of The Mandible, Followed By Rehabilitation With Complete Dentures And Divided Into Two Equal Groups: Group I Patients Receive Locator Attachment, While Group II Receive Equator Attachment. Immediately After Implant Placement The Implant Stability Quotient (ISQ) Reading Of A Minimum Of 60 Was Measured Before Considering Connection Of The Attachment. Then The Denture Was Relieved In The Midline Providing Adequate Space For Female Housing Of The Attachment And Then The Denture Was Picked Up Directly In The Mouth. The Clinical Outcome Evaluated Two Weeks, Three Months And Six Months After Implant Insertion. RESULTS: The Peri-implant Soft Tissues Assessment Results Showed No Statistically Significant Difference Within Each Group And Between Two Groups At Different Evaluation Period, But The Result Of The Probe Depth In The Present Study Showed Statistically Significant Increase Within The Pair Groups, But There Is No Significant Variation Between The Pair Groups. CONCLUSION: Immediately Loaded Single Midline Implant Retained Mandibular Overdenture Treatment With Locator Attachment Could Be An Alternative And Cost Effective Treatment Option And Relatively Simply Treatment.

ABSTRACT
Horizontal Ridge Deficiency In The Anterior Maxilla Represents One Of The Challenging Situation In Bone Regeneration. Guided Bone Regeneration (GBR) Has Become A Major Treatment Option For Such Deficiency To Provide Optimal Bone Quantity For Installation Of Endosseous Dental Implants. However, There Is A Good Prognosis For This Treatment, As The Residual Ridge Height Can Be Used To Stabilize A Bone Graft, Making It Less Subjectable To Move Which Is One Of The Factors That May Lead To Graft Failure. Numerous Technique In Guided Bone Regeneration Have Been Introduced Using A Varies Types, Combinations Of Grafting Materials And Different Types Of Barrier Membranes Either Rigid, Non-rigid Or Resorbable, Non-resorbable Materials.

ABSTRACT


Purpose: Assessment The Accuracy Of CBCT In Detection Of Horizontal Root Fracture By Alternation Of Exposure Parameters In Endodontic Treated Teeth

Materials and Methods: 18 Single-rooted Human Teeth Will Be Selected Then Inspected By Trans-illumination For The Absence Of Root Fracture, And By Conventional Periapical Radiographs To Observe Root Canal Anatomy. Teeth With Caries Extending To The Root, Restorations, Pulp Calci?cations, Root Resorption Or Root Fracture Will Be Excluded. Finally Each Tooth Coded And Divided Into Two Groups:, Nine Teeth With Obturation With Guttapecha Only And Nine Teeth With Obturation With Gutta-percha And With Root Fracture. Then The Roots Of Teeth Will Be Fractured By Hummer With Standardized Force Perpendicular To The Long Axis Of The Tooth. Each 3 Teeth Will Be Mounted Separately In A Blocks That Will Be Made From Silicon Impression Putty. Then The Blocks Will Be Placed In A Fine Plastic Cylinder Containing Water To Simulate Soft Tissue. The Cylinder Will Be Placed On The Chin Rest Of CBCT Unit. The Teeth Will Be Imaged By Centering The Block In A Smallest Field-of-view FOV (H ? D) 50 ? 50 Mm. By Changing In Exposure Parameters (5 MA) With Standardized Resolution, (5 MA) With High Resolution, (10 MA) With Standardized Resolution And (10 MA) With High Resolution We Produce 72 Evaluations Detected By Three Radiologists.
