The result of this study indicates a relationship between the marginal design of the alumina cores and their fracture resistance. For the uninitiated a butt joint finish refers to a preparation that ends in a flat surface (a shoulder) that runs perpendicular to the rest of the prepped tooth. A urethane spindle liner. One of the major problems of all ceramic restorations is their probable fracture against the occlusal force. Regarding ceramic groups (III and IV), shoulder finishing line produced greater marginal gap with ceramic crowns in comparison to chamfer finishing lines but statistically the difference was not significant (Table 4) and (Fig. A deep chamfer is required for a metal-ceramic restoration. chamfer margin (0.7 mm) was prepared. updates international indexed journal peer reviewed monthly print journal double reviewed refereed & referred international journal journal promoted by indian society for health and advanced research When I talk to dentists and technicians alike, most have a preference but there science supports that they work equally well.

There are a host of factors which contribute to the development of rounded shoulders. The mean fracture resistance was 1426N for the chamfer ZirCAD samples, 1361.3N for the shoulder ZirCADsamples, 1059.9N for the chamfer Press samples and 1295.8N for the shoulder Press samples. When preparing a tooth with a modified shoulder margin design chose a modified shoulder diamond. ScienceDirect ® is a registered trademark of Elsevier B.V.
