Use of a silicone index to apply and contour porcelain on occlusal surfaces of ceramometal restorations.
The advantages of this technique are numerous. Complete contour occlusal wax-up detail is identically and accurately reproduced. Cusp and fossa placement are reproduced as dictated by the determinants of mandibular movement. The index acts as a guide in designing the substructure. Even thicknesses of porcelain are easily visualized. Color control is improved. After the first porcelain firing, occlusal contours shrink away from the index. This eliminates subjectivity in the placement of more intensely chromatic porcelains to appropriate areas during the second porcelain application. Porcelain application of a high degree of esthetic appeal and functional character is quickly achieved.
