A traditional radiography is a two-dimensional image of something that actually has three dimensions. At last, thanks to 3D radiological system with a small field of view we have the missing dimension, which exponentially amplifies our knowledge. The CBCT (Cone Beam Computed Tomography) is a real breakthrough for dentistry because it offers many advantages: low radiation dose to patients, high definition with very small voxels, the possibility to see the tooth and the surrounding structures in three different planes, overcoming any anatomical overlapping. It opens a new frontier and allows us to make precise diagnosis where traditional tools were insufficient. Reading the book we can see the enthusiasm and the passion the authors put in writing it. Each chapter is a font of information, every detail has been carefully examined, and each clinical case has been extensively reported. The introductory chapters provide the reader with the knowledge and basic tools to understand the CBCT. Everything else is an atlas, highly enjoyable, which includes the use of CBCT in both clinical and surgical dentistry, and describes in details not only the diagnostic phase but also the operational use to program the individual case, and control the future outcome.
