This book is a compilation of two works in the field of Dentistry related to the specialities of Restorative Dentistry and Dental Prosthodontics. The first work aims to provide, through a case report, information on the CAD-CAM system, its advantages and disadvantages and mode of operation for milling lithium disilicate ceramic blocks because in the current phase of dentistry, CAD-CAM technology brings a new era of aesthetic restorative treatments, with better use of professional time, reduced errors and increased quality through the use of automated techniques. The second study is relevant due to the popularisation of ceramic veneers and ultra-thin ceramic laminates. There is a need to define the correct indication and preparation protocols to guide professionals in clinical practice as to the limitations of each treatment, so the aim of this book is also to describe through a literature review the differences in the indication of the two aesthetic restorative treatments, as well as the variations in preparation methods, difficulties, limitations of the techniques and the differences in adhesive cementation.
