| Summary: | All-ceramic crowns have gained immense popularity in modern day dentistry owing to their enhanced aesthetics, biocompatibility, and durability. Among these, lithium disilicate (LS2), zirconia (Z), and zirconia-reinforced lithium silicate (ZLS) are three most desired restorative materials, each offering varying benefits. The advances of material science and digital dentistry are constantly refining their clinical behaviour, making material selection a major part of restorative decision making. This review article provides a general summary of these three all-ceramic crown materials and discusses their evolution, specifically the development in the translucency of zirconia and the transformation of ZLS as a hybrid material. It covers the most important properties of each of these materials, such as aesthetics, biocompatibility, strength, and bonding procedures. It also discusses the effect of traditional vs. computerised impression methods on their clinical success. A lot of this review also contrasts traditional and digital impression technology. It discusses how developments such as intraoral scanning (IOS) and Computer-Aided Design and Computer-aided Manufacturing (CAD/CAM) technology impact the accuracy, efficiency, and clinical success of crown restorations. Through critical examination of the literature, this review is intended to provide clinicians with information necessary for evidence-based decision making in material selection and impression-taking techniques, which will ultimately maximise patient outcomes and long-term restorative success. |
