Surface Characteristics of Base Metal Dental Alloys Processed by Alternative Procedures

Article Preview

Abstract:

Technological developments in the field of based metal alloys have led to the implementation of novel manufacturing processes in dental practice. The aim of the study was to evaluate surface characteristics of Co–Cr dental alloys fabricated via conventional casting, computerized milling, selective laser sintering and selective laser melting. The morphology and the topography of the samples were investigated by SEM / EDAX (Model INSPECT S) and AFM (Model Nanosurf® EasyScan 2 Advanced Research). Depending on the nature and chemical composition of the samples the morphology is different. The microstructure of Co–Cr dental alloys depends on the manufacturing technique. Given to the differences in microstructural properties among the tested specimens, further differences in their technological achievement and clinical behavior can be anticipated.
