Background There is insufficient evidence recommending a framework material and a CAD/CAM manufacturing technique for mandibular implant-supported prostheses. The study objective was to evaluate the clinical application of different materials and construction techniques used for mandibular All-on-4 prosthesis on circumferential peri-implant bony ch...

Objectives This study aimed to compare the accuracy of implant‐level conventional and digital impressions for atrophied maxillary ridges. Materials and Methods Twelve participants with atrophied edentulous maxillary ridges received six implants. Six months later and after soft tissue maturation around healing abutments, a control cast was construc...

Purpose: This study was conducted to evaluate the clinical peri-implant soft tissue changes during first year after occlusal loading and the ridge base relation after three years for mandibular CAD-CAM manufactured screw-retained implant-supported hybrid prosthesis of polyetheretherketone (PEEK) framework utilized with All-on-Four treatment concep...

Purpose: To investigate retention and stability characteristics of soft-liner and clip attachments used for bar/implant-assisted mandibular overdentures. Materials and methods: Two implants were placed in an edentulous mandibular model. According to the type of bar, presence of cantilevers, and type of attachments, eight groups were tested: (1)...

Objectives The aim of this crossover clinical study was the evaluation and comparison of patient satisfaction and masticatory performance for patients rehabilitated with mandibular two implant overdentures retained with two different bar attachments; zirconia bar and cobalt chromium bar. Material and Methods Twenty completely edentulous patients w...

Purpose: This study aimed to examine clinical and patient-centered outcomes of resilient stud and stress-free bar attachments used for immediately loaded implants supporting mandibular overdentures. Materials and methods: Thirty edentulous patients with sufficient bone mesial and distal to the mental foramen received new dentures. The patients w...

Aim: The aim was to evaluate and compare retention forces of all-zirconia (ZrO 2), all-polyetheretherketone (PEEK), and ZrO 2-PEEK Computer-Aided-Designing computer-Aided-Manufacturing (CAD-CAM) telescopic attachments for two implant-retained mandibular overdentures. Materials and Methods: Fifteen identical acrylic resin models of the edentulous ma...

Mandibular Implant overdenture with two inter-foraminally placed implants has been presented as a minimum standard of care for mandibular edentulous patient. Problems related to the compromised morphology of the edentulous mandible may present, thus deviations from the proposed perpendicular implant axis are required for implant placement. As a con...

Aim: This study aimed to evaluate and compare retention force of two implants retained mandibular overdenture with zirconia bar using two different clip materials. Methodology: 20 completely edentulous patients (8 women and 12 men) with age ranged between 45 and 65 years were selected for this study. All patients received conventional maxillary and...

Abstract Objectives: This study aimed to evaluate patient satisfaction and oral health related quality of life (OHRQoL) of conventional denture, fixed prosthesis and milled bar overdenture for All-on-4 implant rehabilitation. Materials and methods: Sixteen completely edentulous patients with ill-fitted mandibular dentures received new mandibular de...

Abstract Purpose: to compare the effect of different locator abutments height on peri-implant tissue health in retained mandibular overdenture. Material and method: Twelve completely edentulous patient were selected to this study. Each patient will received two implant in the canine area of the mandibular arch using early loading protocol. patients...

Aim: This in vitro study was performed to evaluate and compare stresses applied to the implants retaining mandibular complete overdenture with telescopic attachments of different materials. Materials and Methods: Three identical clear acrylic resin models of completely edentulous mandibular arch were selected for this study. One implant was install...

Purpose: The aim of this study was to compare the effect of three designs for implant-supported mandibular overdenture on the chewing efficiency and electromyographic (EMG) activity of masseter muscles. Material and methods: Eighteen edentulous patients received new maxillary and mandibular dentures (control, CD) before implant placement. After...
