What kind of alloy is used for a resin bonded cast alloy bridge?

Base metal alloy:
Chromium 13-20%
Nickel 70%
Berylium 2-5%

1

How is the alloy surface treated to improve retention?

1) Electrolytic etching
- techinque sensitive andd voids can trap air which can inhibit resin polymerisation
2) Sandblasting
- safer
- less technique sensitive

2

What are the indications for a resin bonded cast alloy bridge?

1) Short eddentulous spaces
2) Sound coronal tooth structure
3) Good periodontal suport of abutmments
4) Good ridge form
5) Cuspid guidence (posterior teeth)

3

What are the contraindications for a resin bonded cast alloy bridge?

1) Large edentulous space
2) Seevre tooth rotations
3) peridontalally compromised abutments
4) poor ridge form
5) alloy hypersensitivity

4

What kind of bridge designs are availible forr a resin bonded cast alloy bridge?

1) Fixed-fixed
2) Cantilever
3) Splint
4) Inlay-onlay
