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 ...
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 ...
Implant-based factor as possible risk for peri-implantitis
(2019-01-01)
Peri-implantitis is currently a topic of major interest in implantology. Considered one of the main reasons of late implant failure, there is an emerged concern whether implant characteristics could trigger inflammatory ...
Comparative Microstrain Study of Internal Hexagon and Plateau Design of Short Implants Under Vertical Loading
(Lippincott Williams & Wilkins, 2016-02-01)
Purpose: To quantify microstrain development during axial loading using strain gauge analysis for short implants, varying the type of fixture-abutment joint and thread design. Materials and Methods: An internal hexagon ...
Fracture of Zirconia Abutment with Metallic Insertion on Anterior Single Titanium Implant with Internal Hexagon: Retrieval Analysis of a Failure
(Dennis Barber Ltd, 2016-09-01)
This case report presents a retrieval analysis of a screw-retained one-piece restoration with the veneering ceramic fired directly onto the zirconia abutment that fractured during insertion. A patient who experienced root ...
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 ...
Photoelastic comparison of single tooth implant-abutment-bone of platform switching vs conventional implant designs
(2011-03-01)
Objectives: The maintenance and stability of peri-implantar soft tissue seem to be related to the crestal bone around the implant platform and different implant designs connections might affect this phenomenon. The aim of ...
