Treating tooth wear has increased over the last two decades . Nevertheless, the treatments involved have not been satisfactory to most patients, nor have they achieved the expected goal on some worn teeth. New approaches have emerged to reconstruct full arches in a minimally invasive way They take advantage of developments in the field of adhesive dentistry. These new concepts constitute a revolution in dentistry and their application requires adapted techniques and training. The purpose of this article is to suggest a precise and reproducible method that simplifies the treatment of worn dentition. A wax up and a mock-up that is mostly used for designing esthetic outcome, and then used as a guide (preparation through the mock up or the wax up- apt for the preparation of anterior teeth). As described by the authors it can as well be used on the posterior occlusal surfaces of the teeth. This will not only provide the exact new vertical dimension of occlusion but will let the dentist use it as a guide for precisely controlling occlusal preparation simultaneously with buccal preparation. The classical cavity design for a partial bonded restoration on posterior worn dentition is also reviewed. The authors believe that during the preparation of the occlusal surfaces of the posterior teeth surfaces the marginal ridges must be preserved to reduce the biological cost and the mechanical stress leading to fracture. A new type of thin and reduced restoration called “table top” is presented.
