What are the dental materials of the fixed partial denture?

Fixed partial dentures as dental restorations, has always been the vast majority of patients the choice, some friends will ask to fixed partial denture materials chosen good, of this time is difficult to answer, because the fixed partial denture materials have their own features, cost will be different.

1. Cobalt-chromium alloys: corrosion resistance, good biocompatibility, the price is higher than the nickel-chromium alloy.

2. All-ceramic materials: biocompatibility best, gum irritation, no allergic reaction. Is a non-metal repair, without any effect on NMR and other examination results. Inadequacies, due to the varying intensity, some of the material is not used to all the teeth, some special processing techniques result in relatively high price.

3. Titanium: contain trace amounts of titanium, is still the nickel-based alloys. High strength, corrosion resistance and oxidation resistance of the basic clinical requirements.

4. Precious metal alloys: excellent corrosion resistance, oxidation resistance, good fit and biocompatibility, is an ideal metal crown repair material. The price is relatively high.

5 Nickel-chromium alloys: the widespread use of an alloy with good strength and metal-porcelain bond, and stable long-term use. The disadvantage is that there will be free of metal components of active metal and chemical properties, long-term use in the mouth causes the gums to the Which include gingival hyperplasia lesions black line, so for the anterior teeth will affect the aesthetic effect. In addition there are some people allergic to nickel, so caution to the known nickel allergy.
