Wear Characteristics of an Experimental High-Strength Fine-Sized Leucite Glass-Ceramic
Abstract
Objectives: To test the wear characteristics of an experimental high-strength fine-sized leucite glass-ceramic against human enamel. Methods: A wear testing protocol was adapted on an MTS-Bionix-858 system. Human enamel pins were wear tested against disc samples (n=12) of a commercial control (Ceramco-3, Dentsply) and an experimental fine-grained leucite glass-ceramic. Specimens were loaded (13.5N) followed by a lateral excursion movement and a controlled cuspal contact time (0.25s) to complete a cycle for 300,000 simulated masticatory cycles at 2Hz under continuous flow of deionised water (37C). Wear quantification (volume/ mean-height loss) was performed by superimposition of digitised test surfaces before and after wear testing by non-contact 3D profilometry (Proscan-2000, Scantron) and the dedicated software using a novel protocol. Glass-ceramic disc/ tooth specimen groups were statistically compared (Mann-Whitney, p<0.05). Wear tested specimens were examined using SEM and Profilometry. Indicative surface roughness (Ra)/ waviness measurements (500 x,y line scans/ specimen) were also performed on a glass-ceramic disc/ tooth pair per group. Results: Volume and mean-height loss results are listed below. A patterned wear profile with distinct parallel grooves was identified for the Ceramco-3 group versus the non-oriented wear profile of the experimental group. All recorded Ra and wave-height values for the experimental disc/ tooth group were lower than the Ceramco-3 group.
