Comparative Analysis of Various Cavosurface Margins in Class II Restorations Using 3D Finite Element Method

International Journal for Numerical Methods in Biomedical Engineering, Volume 41, Issue 4, April 2025.
Within the limitations of this in silico investigation, the results suggest that adding a bevel to a slot restoration can significantly improve the mechanical performance by reducing the tensile stresses and, hence, the possibility of debonding. ABSTRACT The primary aim of these analyses was to evaluate the mechanical characteristics of the restored ...

A Comparison of Zirconia and Titanium Abutments for Microleakage

Clinical Implant Dentistry and Related Research, 2015
AbstractBackgroundMicroleakage through the interface has been documented in implant systems with titanium (Ti) abutments. There is a current increase in the use of zirconia (Zi) abutments especially in esthetic zone in where higher risk of visible metal color through the peri‐implant tissues exists.PurposeThe aim of the present in vitro study is to ...

Acid‐Resistant Glass Ionomer Cements: An Assessment of Their Mechanical Properties, Fluoride Ion Release and Protection to Surrounding Tooth Surfaces From Acid Challenges

Journal of Biomedical Materials Research Part B: Applied Biomaterials, Volume 113, Issue 4, April 2025.
ABSTRACT New acid‐resistant glass ionomer cements (GIC) claim to be able to withstand acidic conditions while also protecting surrounding tooth structures and preserving function. Currently, there are only a few studies that assessed mechanical properties, ion release, and changes that occur around an acid‐resistant GIC–dentine bonded interface under ...
