1: The crown has no metal support, and the aesthetic effect is excellent. ?
2. The density and strength are high, and it can be used as a fixed bridge with more than 6 units. ?
3. Don't interfere with MRI.
4. Good biocompatibility, superior to various metal alloys (including gold); No irritation or allergic reaction to gums.
Because of the high strength, doctors don't have to grind their teeth too much.

Based on the above advantages, it will surely become the mainstream of dental restoration. However, its technical requirements are also very high.

If there is a problem of smiling gums, only making all-ceramic crowns can't solve it. It is necessary to cut the gum by surgery to lengthen the crown, so that the gum is above the low line or slightly above the smile. After the gum and alveolar bone are restored, the all-ceramic crown can be restored, which can solve the problem of gingival smile and short crown. It is suggested that cleaning teeth and periodontal basic examination and treatment should be carried out first.
