Dental cosmetic restoration includes teeth whitening, porcelain-fused-to-metal crowns, all-ceramic crowns, and all-ceramic veneer restorations. Here, we will introduce the advantages and disadvantages of all-ceramic veneer technology.
**Applicability of All-Ceramic Veneers:** If there is no significant damage to the teeth, and the alignment is basically straight but only the color is unsatisfactory, this type of restoration can be used, achieving nearly perfect aesthetic results. It involves uniformly removing a thin layer (about 1mm) from the labial/buccal side (the side facing outward) of the tooth and then reshaping the tooth's form and color using specialized dental ceramic materials. Since the color of the teeth can be precisely controlled, the cosmetic effect is excellent, with wear resistance similar to natural teeth.
**Orthodontics; Porcelain Teeth**
**Advantages:** The amount of tooth reduction is only about half that of conventional porcelain restorations, and it does not damage the contact points or the lingual side of the tooth's hard tissue. As a result, the sensation remains unchanged.
**Disadvantages:** Retention is entirely dependent on adhesive strength, making it prone to detachment under excessive external force. It is generally only used for front tooth aesthetics.
Regarding the application of veneers, many dentists are not very supportive. While veneer technology has the advantage of requiring less tooth reduction, it also has the drawback of being prone to detachment. To reduce this occurrence, opting for an all-ceramic crown might be more practical.
