The success of a clinician is not merely a measure of the impeccable restoration that he creates, but even more the impact on the lives of those who utilize what he creates. thus so-called "minimally invasive" bonded partial restorations now occupy an essential place in the modern therapeutic arsenal, either to overcome the limitations of direct restorations or, on the contrary, to offer the patient an alternative to coronal-peripheral restorations, which are considered to be more damaging to the dental organ. It will be a question of privileging the most conservative therapies possible while responding to an ever-increasing demand from patients and practitioners in terms of aesthetics but also in terms of durability and longevity. This book aims on describing various inlays and onlays in detail with their indications, contraindications, advantages and disadvantages.
