Validation of finite-element simulations with synchrotron radiography – A descriptive study of micromechanics in two-piece dental implants

Heliyon, 2018
State-of-the art, two-piece dental implants made from titanium alloys exhibit a complex micromechanical behavior under dynamical load. Its understanding, especially the formation of microgaps, is of crucial importance in order to predict and improve the ...

Influence of Implant Connection, Abutment Design and Screw Insertion Torque on Implant-Abutment Misfit

, 2020
Background: An accurate fit at the implant-abutment interface is an important factor to avoid biological and mechanical complications. The aim of this study was to evaluate the marginal misfit at the implant-abutment interface on external and Morse taper

Bone remodeling of dental implant comparing between the customized titanium abutment and commercialized stock abutment and positioning of the implant placement depth: A 3D finite element analysis

Digital Dentistry Journal
Objective: Implant failure has been associated with the distribution of occlusal load and improper biomechanics of the dental implant. Although subcrestal implant placement has been shown to provide several benefits, there is still some disagreement when

Development of the nasal capsule in Emydura subglobosa (Testudines: Pleurodira) with a comparison to other turtles

The Anatomical Record, EarlyView.
Abstract Extant turtles occupy freshwater, marine, and terrestrial habitats, and their nasal region provides important evidence for the evolution of respiration‐ and sensory‐related cranial morphology. However, developmental data on the turtle nasal capsule remain limited, particularly in Pleurodira.

Stability of implant–abutment connection in three different systems after fatigue test

The Journal of Indian Prosthodontic Society, 2022
Aim: Abutment screw loosening of implant-supported prosthesis causes a mismatch between the abutment and the implant. This screw loosening is influenced by the implant–abutment connection type, however, with contradictory results reported in different ...

Impact of implant abutment connection designs and cyclic loading on screw stability in dental implants: A systematic review and meta-analysis

The Journal of Prosthetic Dentistry
Screw loosening is a common mechanical complication that can compromise the long-term success of implant-supported restorations. Implant-abutment connection design and cyclic loading influence load transfer, preload retention, and joint stability; however, their specific contributions to screw loosening under functional conditions remain unclear.The ...
