Prosthetic treatments have undergone considerable evolution in recent years, mainly through the use of materials. Not only has the consolidation of materials such as lithium disilicate or zirconium oxide been confirmed, but new materials, either ceramic or hybrid, have also appeared to try to compete with them. The constant evolution in this field forces us to update and describe the precise indications of each one of them based on aesthetics and mechanical properties, as well as all the details related to their clinical manipulation, all in order to to be able to handle these materials in a predictable way in our clinical practice.
On the other hand, the presence in our consultations of patients with large wear is becoming more frequent, either only at the level of the anterior teeth or also at the level of the posterior teeth. In these patients there are a series of decisions that must be made that are key to the success of our treatment, such as when to restore only the anterior teeth or when it will be convenient to increase the vertical dimension, what is the first step in planning treatment of worn cases, how we will gain space for the restorative material by palatine, when it will be necessary to resort to other disciplines to complement our treatment, what material will be the most suitable to restore functional areas or what type of restorations will be of choice (vestibular veneers, double veneers or crowns). On the other hand, despite the fact that aesthetics is important, function is not less important and it will be essential in cases of short clinical crowns that we must lengthen, provide a harmonious and effective anterior guide, although as a previous step it should be ruled out that it does not there is a constraint on the function envelope. Lastly, it is necessary to have a clear protocol for increasing the vertical dimension of occlusion, a protocol that describes in detail each of the steps sequentially to resolve the most demanding situations both aesthetically and functionally.
This book provides an answer to all these questions while addressing other important aspects such as those related to the modeling of pontic spaces both in healed ridges and in post-extraction ridges or the cementing protocol of the different ceramic systems and hybrid materials. In addition, a chapter is dedicated to the treatment with porcelain veneers, another describes in depth the subject related to color and color diagnosis, another deals with photography from a very practical point of view and, finally, a chapter focuses on the digital flow, the present and future of prosthodontic procedures.
