Analysis of the abutment-implant platform gap in internal hex dental implants
(Scientific Publishers of India, 2017)
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 ...
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. ...
Mechanical analysis of conventional and small diameter conical implant abutments
(KOREAN ACAD PROSTHODONTICSSEOUL, 2013-08-02)
PURPOSE. The aim of the present study was to evaluate if a smaller morse taper abutment has a negative effect on the fracture resistance of implant-abutment connections under oblique compressive loads compared to a ...
Bacterial contamination along implant-abutment interface in external and internal-hex dental implants
(E-Century Publishing Corporation, 2014)
Influence of Ceramic Materials on Biomechanical Behavior of Implant Supported Fixed Prosthesis with Hybrid Abutment
(2019-05-30)
PURPOSE: This study evaluated the stress distribution in different cement-retained implant-supported prostheses with a hybrid abutment. MATERIALS AND METHODS: Two factors were evaluated: restorative material for the crown ...
Comparison of the Morse Cone Connection with the Internal Hexagon and External Hexagon Connections Based on Microleakage - Review
(2021-01-01)
The gap formed at the abutment-implant interface brings about a bacterial colonization. In addition, a bacterial reservoir can be established within the implant. The build-up of microorganisms around the implant can cause ...
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 ...
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 ...
Reverse torque evaluation in indexed and nonindexed abutments of Morse Taper implants in a mechanical fatigue test
(2019-03-01)
Background: This experimental study assessed reverse torque of indexed and nonindexed (NI) abutments in Morse Taper (MT) implants in a mechanical fatigue test. Materials and Methods: In this experimental study It was used ...
