Investigation of Nickel Ion Release from Stainless Steel Crowns by Square Wave Voltammetry

International Journal of Electrochemical Science, 2012
No effort has been made to define nickel magnitude from stainless steel crowns in oral environment. Nickel ions released in sufficient quantities from nickel-containing alloys may induce nickel sensitization or elicit allergic contact dermatitis. In this

Bone stability after regenerative peri‐implantitis treatment: A 10‐year follow‐up case study

Clinical Advances in Periodontics, EarlyView.
Abstract Background Peri‐implantitis poses a significant challenge to implant longevity, leading to progressive bone loss and potential implant failure. While reconstructive surgery has been proven effective in regenerating peri‐implant tissues, the long‐term stability of the regenerated tissues and the impact of supportive peri‐implant care (SPIC) on ...

Investigation on tunnel stability considering pipe‐roof support with transparent soil technology

Deep Underground Science and Engineering, EarlyView.
This study integrates transparent soil technology, 3D reconstruction and numerical simulation to captures the full‐field deformation of shield tunnel instability. Results demonstrate that pipe‐roof support enhances stability via the “soil‐arching barrier effect,” effectively restraining failure wedge development by extending stress transfer paths ...
