Lumineers advantages and disadvantages
Benefits of using lumineers ( + )
- Have a natural and lasting color.
- Ideal optical reflective effect similar to the enamel. Lumineers have full transparency. One of the main properties of enamel - transparency. This means that when light hits the surface of the enamel, it is not immediately reflected and partially penetrates into the enamel layer. Then this light is reflected from an opaque layer of tooth under the enamel. This transparency makes the tooth enamel distinctive appearance. Previously to improve the appearance of teeth used materials that were opaque or transparent, ie when restoring teeth with these materials do not ensure transparency. Therefore, light rays could not penetrate into the dental tissues deeply and directly reflected from the surface of these materials. Thus, these materials do not provide a complete resemblance to natural teeth, but only improves the appearance of a tooth. Light falling onto the surface of the Lumineers, can penetrate a certain depth inside the ceramics, and then reflected from the dental tissues. Therefore, a ceramic veneer is no different from the adjacent teeth.
- Lumineers are resistant to staining. Earlier in dentistry for esthetic restorations using different materials. They had one drawback - changing colors, stains. This was due to the fact that these materials were permeable. By eating foods that have coloring properties (tea, coffee, wine, tobacco) changed the color of these restorations, spots appear on the teeth. Compared with these materials, Lumineers have the advantage that the surface of ceramic, but it is smooth and impervious. Itself glazed ceramic surface is resistant to dyes. Therefore, on the surface of the veneer stains do not happen.
- Lumineers have a characteristic strength of porcelain, which allows you to change the shape.
- Lumineers have excellent biocompatibility with the tissues of the gums. On the ceramic surface to a lesser extent accumulated plaque.
- Lumineers have great resistance to abrasion and wear.
- Longevity.
Another side of lumineers ( - )
- One of the main disadvantages of Lumineers is that they break down. When the veneer breaks, it can not be restored. In this case, the only solution is to replace a new one.
- If the veneer is just exfoliate from the tooth, then it can be glued back.
- Repair chipped Lumineers after cementation of tooth enamel is possible, but these designs are already short-lived due to the formation of pigmentation. Since these chips are restored with composite materials, there is a possibility of pigmentation on the border between the Lumineers and composite materials.
- Manufacture of Lumineers - an irreversible process, ie, in the manufacture of veneers dissects the hard tissue of teeth.

- Complexity in manufacturing techniques, fixation, time-consuming.
- After fixing the veneer to change its color is very difficult.
- Acidic foods can alter the surface of the ceramic lumineers veneer.
