Implant Overdenture Abutment Loosening Under Hyperbaric Conditions, Zana Jamal Al-Saloum

Graduate Theses, Dissertations, and Problem Reports (ETD)

Objectives: To investigate the effect of various hyperbaric air pressures on the loosening of LOCATOR® (ZEST Anchors, LLC, Escondido, CA USA) overdenture abutments.

The pressure conditions tested are meant to simulate scuba diving conditions in edentulous patients that are restored with implant-retained tissue-supported overdentures. Another sub-goal of this study is to determine whether or not there is a difference in LOCATOR® loosening when the sample is exposed to six cycles/dives as opposed to one cycle/dive.

Methods: 36 ZimVie Tapered Screw Vent Implants with a 3.5mm diameter implant platform, and a 2.5mm diameter (and 1.5mm deep) internal hexagon were …

Comparison Between Two Different Attachment Caps Used In Locator Attachments Of Implant Supported Overdentures (In-Vitro Study), Hossam Eldein Faisal Haridy, Hebatalla Mahmoud El Afandy, Mohammed Farouk Abdalla, Ahmed Mohammed Osama

Future Dental Journal

Purpose: To compare different retentive cap material used in LOCATOR attachments, namely the nylon retentive cap versus PEEK retentive caps, and measure the loss of retention over a period of two years, through 2880 cycles of insertion and removal. Materials and methods: Two implants 3.8mm x 10.5mm were inserted into a clear epoxy resin cast, through a surgical guide, with the implants being 23mm apart. Two LOCATOR attachments with 5 mm gingival height were screwed to the implants, custom made nylon caps were fabricated as an exact replica of the PEEK retentive caps, then two dentures were constructed …

Evaluation Of Strength Of Different Resin Materials Used In Overdenture, Mohamed Emam, Hesham E. Alam El Deen, Hamdy Abu El Fotoh, Ayman Fateen

Future Dental Journal

Introduction: Finding a suitable material that could be used to restore relatively small inter-arch spaces in which reasonable aesthetics as well as good functional strength could be achieved is a difficult process that requires good understanding of the clinical situation and precise management. Historically Metal used to offer the smallest possible thickness with excellent strength but lacks resiliency with poor aesthetics.

Aim of the study: This In-vitro study was conducted to compare two different aesthetic materials PEEK and ACETAL regarding their mechanical strength when used as Overdenture framework in a relatively small thickness.

Material and Methods: 120 specimens were …

Comparison Of Implant-Retained Overdenture And Conventional Complete Denture In The Edentulous Mandible: A Survey Study To Measure Patients' Satisfaction And Quality Of Life In Dental School Clinical Environment, Ahmad Kutkut

Theses and Dissertations--Clinical and Translational Science

Patient satisfaction and quality of life are integral parts of assessing the quality of oral health care. Current aging population trends suggest a growing need to understand the effects of edentulism on oral health and quality of life. As the proportion of aged Americans expands, there will be an increased need to understand treatment options and patient communication strategies. In addition, as new treatment options and innovative technologies emerge, it will be essential to understand patients' concerns and identify best practices associated with denture treatments' individual fit and function. Advanced denture treatments can now be fabricated using CAD/CAM digital denture …

Effect Of Two Different Attachments On The Supporting Structures And Masticatory Capacity Of Implant Retained Mandibular Overdenture, Fardos N. Rizk

Dentistry

Aim: This study was conducted to compare the effect of ball and socket attachment and GPS attachment in implant retained mandibular overdenture cases regarding changes in: crestal bone height and density surrounding implants, electromyographic activity of temporalis and masseter muscles and occlusal biting force. Materials and Methods: Following two stage surgical protocol twelve completely edentulous patients received two implants placed bilaterally in the canine region (24 implants) to retain mandibular overdenture. Four months following the surgery patients were randomly divided into two equal groups; Group-I received ball and socket attachment while Group-II received GPS attachment upon which mandibular overdentures were …

Comparative Evaluation Of Two Different Castable Bar Attachments In Implant Retained Mandibular Overdenture Cases, Fardos N. Rizk

Dentistry

Objective: This research was carried to evaluate which solitary attachment; OT Cap Ball attachment or OT Cap Equator Profile attachment mounted on a bar splinting two implants retaining mandibular overdenture is more favorable regarding crestal bone height and bone density changes surrounding the implants using cone beam computed tomography. Materials and Methods: Following two stage surgical protocol twelve completely edentulous patients received two implants placed bilaterally in the canine region (24 implants) to retain mandibular overdenture. Four months following the surgery patients were randomly divided into two equal groups; Group-I received two OT Cap Ball attachments mounted on a bar …

Comparative Study Of Ot Equator Profile Attachment Versus Gps Attachment In Implant Retained Mandibular Overdenture Cases, Fardos N. Rizk

Dentistry

Aim: This study was carried out to evaluate whether OT Equator Profi le attachment or GPS attachment is less destructive to crestal bone around implants and to bone in distal aspect of the ridge in implant retained mandibular overdenture cases. Materials and Methods: Following two stage surgical protocol twelve completely edentulous patients received two implants placed bilaterally in the canine region (24 implants) to retain mandibular overdentures. Four months following the surgery patients were randomly divided into two equal groups; Group-I received OT Equator Profi le attachment while Group-II received GPS attachment upon which mandibular overdentures were retained. Once patients …

Radiodensitometric Evaluation Of The Effect Of Low Energy Laser Irradiation With And Without Anioxidant Therapy On Immediately Loaded Implant Supported Overdenture, Fardos N. Rizk, Mouchira Salah Eldin Prof.

Dentistry

objective: The purpose of this study is to compare the bone height and density around immediately loaded implants placed in the canine area supporting a mandibular overdenture in four different groups. The first group received low level laser therapy and antioxidants. The second group received antioxidants only. The third group received low level laser therapy only. The fourth group (control group) received no therapy. materials and methods: Following one stage surgical protocol twenty four implants were inserted bilaterally in the canine region to support mandibular overdentures for twelve completely edentulous patients in the form of two implants per patient. Patients …

Hyperbaric Oxygen Therapy For Promoting Osseointegration Around Dental Implants In Heavy Smokers, Fardos N. Rizk, Nasser Shaheen

Dentistry

Objective: The purpose of this study is to evaluate the effect of hyperbaric oxygen (HBO) therapy on osseointegration of implants supporting mandibular overdenture in heavy smokers. Materials and Methods: Following two stage surgical protocol twelve completely edentulous male heavy smokers received implants placed bilaterally in the canine region to support mandibular overdenture. On the second day after the surgery patients were divided randomly into two equal groups. Patients of group I were placed on a protocol of five consecutive sessions of HBO therapy, while patients of group II received no therapy and served as control. Four months following the surgery …

The Effect Of Two Different Implant Systems On Bony Changes In Mandibular Implant Supported Overdenture, Fardos N. Rizk, Eatmad Elrekaby, Azza Farahat

Dentistry

objective: This study was conducted to evaluate the bone changes that may occur around Legacy I implants and NanoTite Tapered implants supporting mandibular overdentures utilizing cone beam computed tomography (CBCT). materials and methods: Fourteen completely edentulous male patients were randomly divided into two equal groups. Group I: Each patient received two Legacy I implants. Group II: Each patient received two NanoTite Tapered Implants. All implants were inserted bilaterally in the mandibular canine region. For all patients conventional complete dentures were constructed before implants placement. After complete osseointegration of implants, dome shaped healing collars were screwed to the implants upon which …
