Strength of all-ceramic crowns is influenced by the margin design -

A recent study performed at NIOM showed that a modified design of the crown margin gave stronger crowns without jeopardizing the aesthetics.

Load at fracture of monolithic and bilayered zirconia crowns with and without a cervical zirconia collar -

The effect of anatomic contour design in all or parts of zirconia crowns is uncertain regarding clinical reliability and survival rates.

Materials for indirect restorations -

The overall topic of NIOM’s presentation at the Norwegian Dental Association’s annual meeting and Swedental in 2015 was Materials for indirect restorations; both metals and all-ceramic materials.

The effect of margin curvature on load at fracture of ceramic crowns -

The aim of this study was to use a clinically relevant test method to evaluate the effect of the curvature of the cervical crown margins on load at fracture

Guidance on the Determination of Potential Health Effects of Nanomaterials Used in Medical Devices -

This Guidance addresses the use of nanomaterials in medical devices and provides information for risk assessors regarding specific aspects that need to be considered in the safety evaluation of nanomaterials. According to the EU Recommendation for the definition of a nanomaterial (Commission Recommendation 2011/696/EU, EC 2011) any particulate substance with at least one dimension in the size range between 1 and 100 nm is considered a nanomaterial.
