The past decade has been witness to a revolution in the art and science of endodontics. In a similar vein, adhesion dentistry has opened the door to restorative possibilities heretofore unimaginable. Advancements in the science and the materials involved have produced stronger porcelains that are no longer traumatic to the opposing natural dentition. These two disparate but uniquely linked disciplines have become increasingly confluent by virtue of these dynamic changes. This sagittal view demonstrates the interconnection of the finished endodontic procedure in maxillary and mandibular bicuspids with the minimalistic preparation for the atypical porcelain crown.
Composite resin is used to create a subfloor as well as the elimination of axial undercuts.
The flat subfloor surface facilitates the creation of a restoration with a positive seat which eliminates the possibility of fracture. This sagittal view of maxillary and mandibular molars demonstrates the degree of occlusal clearance required for these restorations. 2 mm in support cusp areas is essential and a minimum of 1.5 mm elsewhere is required. Of important clinical note, there is no such thing as a maximum of porcelain presence. Traditionally, the design parameters of a full coverage restoration have involved the reduction of intact, healthy, coronal tooth structure.
