A fixed denture is actually a porcelain bridge. The three are connected together. The two adjacent teeth are ground off and then installed to repair one or more missing teeth. The metal materials include nickel-chromium alloy and cobalt-chromium alloy. Zirconia, aluminum oxide and cast ceramics, etc., different materials will affect the service life. For example, metal crowns may stimulate gum inflammation, and all-ceramic teeth have more advantages.
How long does it take to fix dentures?
- After normal use for about 10 years, you can consider replacing the porcelain teeth. After all, after chewing for a long time, the adhesive will fall off, and gaps may be formed. Food residues will enter the crown. After bacteria grow, it will also irritate the gums. Inflammation, even the abutment teeth decayed and rotted.
- In addition to the materials, cleaning and maintenance are necessary after installation. For example, the gap between the teeth on both sides of the porcelain dental bridge is likely to be affected by residue. The groove bone is absorbed, and even the roots of adjacent teeth are gradually exposed.
How to extend the service life of fixed dentures?
- Don’t chew hard food too much. Metal porcelain teeth are easy to collapse and become loose, causing gaps.
- After the fixed denture is installed, the crown and the tooth body should be tightly combined, if not, they should be bonded again.
- The bite must be comfortable, and if it hurts even after eating, try to grind the height of the crown, otherwise it will reach the right bite. If the crown is low, you have to reinstall it.
- If possible, it is best to install all-ceramic teeth, especially for allergic physiques, which will not affect the gums and can also avoid porcelain collapse.
- Regular review once a year. After meals, water floss to remove the clogged residue, reduce the accumulation of dental plaque, and ensure the normal use of the porcelain dental bridge.
- In clinical practice, there are many patients with pontic replacements and the abutment teeth of patients have different degrees of caries. Serious abutment teeth have been decayed, so if there is no problem after more than ten years, they must be replaced to confirm the quality of the abutment teeth. .
In addition to the materials for fixed dentures, the most important thing is crowning technology and post-maintenance. Generally, it takes 10 years to be fine.
Conclusion: The material of chrome cobalt partial denture is a vital for the patient, more over the dental technican handle the restoration data from dentist facebow mounting should be caliration.
