CONDITIONS NOT TO USE DENTAL LAMINATE
in General, Porcelain Laminate
Using dental laminate on some teeth or some people can cause problems.
TEETH TO BE STRENGTHENED
Teeth that have lost a significant part due to abrasion, fracture or decay and teeth with large amounts of filling are not suitable candidates for porcelain laminate application as dental laminates only improve the appearance, not strengthen the teeth. If the tooth on which the Dental Laminate is placed is not strong enough to prevent bending, it may crack or break over time. In such cases, crown coating is a much more suitable solution.
TEETH WITH NOT ENOUGH DENTAL ENAMEL
When porcelain laminates are not adhered to tooth enamel, they cannot be firmly attached to the tooth.
When dental laminate is adhered to tooth enamel, which is harder than porcelain veneers, absorbs most of the force applied to the tooth.
When the Dental Laminate is directly adhered to the dentin layer (the layer under the tooth enamel), as the porcelain laminate is harder than dentine, most of the force applied to the tooth accumulates on the coating. This may cause the coating to separate from the tooth or to break.
There may be insufficient amount of enamel left on the tooth due to reasons such as abrasion, trauma, old dental arrangements and tooth enamel erosion (erosion on the teeth due to exposure to acidic foods / drinks or stomach acid). If there is not enough enamel on the tooth, crown coating is a much more appropriate choice.
TEETH WITH EXCESSIVE FORCE APPLIED
People who clench or grind their teeth or whose upper teeth and lower teeth are in contact with their upper teeth when they close their mouth are not suitable candidates for dental laminate. Significant forces that arise in such situations can cause dental laminates to break or separate from teeth. In a scientific study conducted in 2012, it was found that the habit of clenching / grinding teeth increased the probability of failure in dental laminate applications by 8 times.
Stronger materials can be used as a precaution against the risk of breakage. However, when the ceramics produced with these materials are used, a less realistic image is obtained.
