BIOMECHANICAL ANALYSIS OF DIFFERENT MODES OF THE SAME COMPOSITE CEMENT USING THE DIGITAL IMAGE CORRELATION METHOD
Апстракт
Recently, resin based cements have become very popular in dental practice for cementation of dental restorations, especially considering all-ceramics, due to improved adhesion features. The aim of this study was to visualize and compare strain in the self-cured and dual-cured MaxCem Elite and to investigate hardness of these two curing modes of the same cement. Strain field was measured using 3D optical system Aramis 2M (GOM, Braunschweig, Germany) based on digital image correlation method. Ten, 5 × 2 mm sized samples of the self-cured and dual-cured Maxcem Elite (Kerr, Orange, CA, USA) were prepared by filling plastic ring-type molds. Analysis of the strain fields was done using sections and stage points created by software. The distribution of the overall strain was found to be more expressive and uniform in the self-cured samples. Overall shrinkage strain ranged from 0 to 12%. Samples with dual-curing mode showed higher strain peripherally, compared to self-cured samples where the o...verall strain was distributed all over the
sample surface. The Vickers measurements could not be carried out on self-cured samples due to
incomplete chemical polymerization. The values of hardness were relatively equal in dual-cured Maxcem Elite due to hardness is interpreted as a statistical magnitude practically depends on the composition of the tested structure. Additionally, closeness between cements layers and led lamp was a factor for increasing hardness values in dual–cured Maxcem Elite. The study provided valuable data about strain behavior of Maxcem Elite during polymerization and highlighted dual-cured over self-cured mode.
