All Ceramic Bridge with CAD CAM Milled Zirconia Framework

In milled-porcelain core bridge, computer controlled technology is used to mill the framework instead of using the casting or the lost wax technique. Block of porcelain (zirconia) is cut by computer aided design/computer aided manufacturing system to produce the prosthodontic framework. The outer surface is made from compatible conventional porcelain. The fit is almost always accurate.

Compatible conventional ceramic (coefficient of thermal expansion) is overlaid onto the Zirconia core which is responsible for the improved translucency.

Advantages
1. Excellent esthetics.
2. Metal free without losing strength.
3. Good shade stability.
4. Less laboratory time for the construction of zirconia framework.
5. Excellent adaptation to the prepared abutment.
6. Avoids the hand made aspects of convention FPDs.
7. All ceramics are essentially noncorrosive by nature.
8. All ceramic materials have low affinity to plaque.
9. Very low temperature conduction.

Disadvantages
1. Expensive equipment.
2. Special training for the technician.
3. Obtaining the Chameleon effect is difficult because of stark white color of zirconium dioxide ceramic framework.
