Metal

i. Ceramometal types/brands:

1. a) High noble cast
2. 1. Benchmark C (Jelenko) Used for most ceramometal crowns and bridges.
   2. Jelfine 52 (Jelenko) is the original gold-platinum alloy used for ceramometal. Used for crowns and bridges when a more yellow alloy is desired.
   3. GoldTech Bio 2000 (Argen) is a 99+% gold alloy used when an extreme yellow color is desired for enhanced esthetic results. Note that because of the soft nature of this alloy a 360 ceramic margin must be used. Indicated for esthetic single units or short anterior bridges.
3. b) Complex noble alloys
4. 1. Captek is a gold palladium alloy that is bright yellow and may enhance esthetic results. It is very biocompatible and can be used for crowns and bridges.
5. c) Non-noble alloys
6. 1. Rexillium V (Pentron) is a nickel chrome alloy that can be used for any ceramometal restoration. Commonly it is used for bonded bridges

ii. Cast Metal Restorations

1. a) High & non-noble alloys
2. 1. Firmilay (Jelenko) is used for inlays, onlays, crowns, and bridges.
   2. Rexillium V is used for cast dowel cores

iii. Composite over metal restorations

1. a) Non-noble alloys
2. 1. Rexillium V is recommended for all composite over metal restorations like inlay retained bridges and anterior veneer bridges. Indirect composite over Rexilliun V is a good choice for long span bridges or long term temporaries.
