Effect of Abutment Geometry and Luting Agents on the Vertical Marginal Discrepancy of Cast Copings on Implant Abutments: An in Vitro Study
(Hindawi, 2021)
Aim. Vertical marginal discrepancy (VMD) influences the success of implant-supported restorations. However, there is little literature that has investigated the influence of geometry and cementing agent on changes in VMD ...
Carbon Film Coating of Abutment Surfaces: Effect on the Abutment Screw Removal Torque
(Lippincott Williams & Wilkins, 2014-08-01)
Purpose: To evaluate the effect of diamond-like carbon (DLC) coating of prefabricated implant abutment on screw removal torque (RT) before and after mechanical cycling (MC).Materials and Methods: Fifty-four abutments for ...
Mechanical behavior of different micro conical abutments in fixed prosthesis
(2018-01-01)
Purpose: To evaluate the biomechanical behavior between two different micro conical abutments: two-piece and one-piece abutments. Materials and Methods: Four groups were divided according to the prosthetic connection ...
Mechanical behavior of titanium and zirconia abutments at the implant-abutment interface: A systematic review
(2022-01-01)
Statement of problem: Zirconia has become popular for dental implant abutments in the esthetic zone but can damage the implant connection interface. Studies have been conducted to compare zirconia abutments with conventional ...
Effect of the number of abutments on biomechanics of Branemark prosthesis with straight and tilted distal implants
(USPPorto Alegre, 2010)
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 ...

Analysis of the Mechanical Behavior and Effect of Cyclic Fatigue on the Implant-Abutment Interface
(Facultad de Odontología. Universidad de Costa Rica, 2021)
FEA and microstructure characterization of a one-piece Y-TZP abutment
(Elsevier B.V., 2014-11-01)
Objectives. The most important drawback of dental implant/abutment assemblies is the need for a fixing screw. This study aimed to develop an esthetic one-piece Y-TZP abutment to suppress the use of the screw.Methods. ...
Failure modes of Y-TZP abutments with external hex implant-abutment connection determined by fractographic analysis
(2016-07-01)
Yttria-stabilized tetragonal zirconia (Y-TZP) was introduced as ceramic implant abutments due to its excellent mechanical properties. However, the damage patterns for Y-TZP abutments are limited in the literature. Fractographic ...
Effectiveness of screw surface coating on the stability of zirconia abutments after cyclic loading
(2012-01-01)
Purpose: Different surface treatments have been developed in attempts to prevent the loosening of abutment screws. The aim of the current study was to compare the effectiveness of titanium alloy screws with tungsten-doped ...
