The use of restorative techniques and trends has evolved over time. Certain material advancements have significantly transformed the field of dentistry, while some original concepts have faded into insignificance. Today, the field of dentistry continues to expand the use of all-ceramic restorations, from pressed-ceramic techniques and materials to the increasing use of zirconia and new materials derived from CAD/CAM technology. In this article, we examine the challenges of slicing lithium disilicate ceramic material using the mist flow-aided W-ECDM process. Due to its superior properties, lithium disilicate ceramic ingots are widely used in dental applications and have gained significant popularity in dental reconstruction. This paper investigates the general challenges associated with micromachining lithium disilicate ceramic ingots using the wire-ECDM process and explores how its composition contributes to these difficulties. The surface morphology of the machined material is also examined in this study.
