Edentulism is one of the most significant problems given increase in elderly population. The aim present investigation to evaluate a case report with angled screwdriver solutions and new kinds low-profile attachments full arch rehabilitation divergent implants. In this clinical we will analyze how abutments channel OT Bridge system (Rhein83, Bologna, Italy) can be predictable solution over time...

PURPOSE All-ceramic abutments are employed increasingly often in implant dentistry for esthetic reasons. In vitro stress testing is required to evaluate the suitability of these constructions, especially in load-bearing posterior regions. The purpose of the study was to assess and compare the fatigue and fracture resistance of one- and two-piece computer-aided design/computer-assisted manufactu...

PURPOSE To compare marginal and internal gaps of zirconia substructure of single crowns with those of three-unit fixed dental prostheses. MATERIALS AND METHODS Standardized Co-Cr alloy simulated second premolar and second molar abutments were fabricated and subsequently duplicated into type-III dental stone for working casts. After that, all zirconia substructures were made using Lava™ system...

PURPOSE The aim of this study was to examine the bending moments and fracture patterns of different zirconia abutments with internal implant-abutment connections after static loading and to compare their bending moments to those of internally connected titanium abutments. MATERIALS AND METHODS Three types of customized zirconia abutments (Straumann CARES abutments/Straumann BL implants [T1], ...

INTRODUCTION Implant-supported prostheses have to overcome a major difficulty presented by the morphology and esthetics of peri-implant tissues in the anterior sector. Diverse therapeutic techniques are used for managing the mucosa adjacent to the implant and the most noteworthy is immediate/deferred fixed provisionalization. OBJECTIVES In vitro testing of strength and deformation of implant ...

The occurrence of bridge collapse is frequently attributed to the prevalent erosion in vicinity abutments. Accurate determination maximum scour depth abutments imperative ensure a secure and reliable design. phenomenon local at can exhibit significant variations when compared open-flow conditions, primarily due additional obstacle posed by presence ice cover. Research has demonstrated that more...

PURPOSE This in vitro study aimed to evaluate the effect of implant connection design (external vs. internal) on the fit discrepancy and torque loss of zirconia and titanium abutments. MATERIALS AND METHODS Two regular platform dental implants, one with external connection (Brånemark, Nobel Biocare AB) and the other with internal connection (Noble Replace, Nobel Biocare AB), were selected. Se...

BACKGROUND Screw loosening of implant restorations continues to be a complication in implant prosthodontics. Screw joints are subjected to a loss of initially applied torque because of friction and component misfit. It has been suggested that the loss of applied torque is less in machined metal abutments than in cast plastic abutments. PURPOSE This study compared the loss of applied torque (d...

OBJECTIVE This study aimed to evaluate the bending moments, and compressive and tensile forces in implant-supported prostheses with three, four or five abutments. MATERIAL AND METHODS Ten Pd-Ag frameworks were tested over two master models with: 1) parallel vertical implants, and 2) tilted distal implants. Strain gauges were fixed on the abutments of each master model to measure the deformati...
