Surface Roughness and Wear Behavior of CAD/CAM Ceramics Against Vita Mark II
Objectives
This study aimed to assess the surface roughness (SR) and wear behavior of computer-aided design/computer-aided manufacturing (CAD/CAM) ceramics when compared to a feldspathic ceramic.
Material and Methods
This in vitro study was conducted on three groups of CAD/CAM ceramic blocks (n = 10 each): a zirconia-reinforced lithium silicate ceramic, a polymer-infiltrated ceramic network, and a resin nanoceramic. Additionally, 40 feldspathic ceramic blocks and 10 bovine incisors were used as antagonist materials. Surface roughness was measured by profilometry before and after wear testing (49 N, 120,000 cycles, 30 cycles/min). Wear depth was quantified using 3D scanning and image analysis software. Data were analyzed using ANOVA and paired t-tests (α = 0.05).
Results
Before wear testing, the zirconia-reinforced ceramic showed significantly higher SR than the other groups (p = 0.00). All groups exhibited a significant reduction in SR after testing (p = 0.00). Posttest SR varied significantly between most groups (p < 0.05), except between natural enamel and the resin nanoceramic (p = 0.986). Wear depth differed significantly among the materials (p < 0.001), with natural enamel showing the lowest wear, comparable only to the resin nanoceramic (p > 0.05).
Conclusions
All tested CAD/CAM ceramics underwent substantial wear and SR reduction when opposed by feldspathic ceramic. The resin nanoceramic demonstrated the closest wear behavior to natural enamel and may be the most suitable restorative material for contact with feldspathic ceramics.
期刊介绍：
Clinical and Experimental Dental Research aims to provide open access peer-reviewed publications of high scientific quality representing original clinical, diagnostic or experimental work within all disciplines and fields of oral medicine and dentistry. The scope of Clinical and Experimental Dental Research comprises original research material on the anatomy, physiology and pathology of oro-facial, oro-pharyngeal and maxillofacial tissues, and functions and dysfunctions within the stomatognathic system, and the epidemiology, aetiology, prevention, diagnosis, prognosis and therapy of diseases and conditions that have an effect on the homeostasis of the mouth, jaws, and closely associated structures, as well as the healing and regeneration and the clinical aspects of replacement of hard and soft tissues with biomaterials, and the rehabilitation of stomatognathic functions. Studies that bring new knowledge on how to advance health on the individual or public health levels, including interactions between oral and general health and ill-health are welcome.
