韓国歯科 Compared to other resin-based composites, TEGDMA is less toxic and more durable. It also has a lower stain resistance and is easier to apply. Many dentists choose TEGDMA for a variety of reasons. Here are a few of them. In addition to these advantages, it is also easier to work with and is available in a wide variety of colors. You can 韓国歯科 learn more about it in this article.
TEGDMA is less toxic than other resin-based composites
The release of TEGDMA from SDR bulk-fill composites was determined by HPLC. The polymer eluted to a greater extent from ethanol and 75% ethanol than distilled water. The elution of TEGDMA from a 4 mm-thick sample was the least affected by doubling the energy applied to it. The TEGDMA elution rate was the lowest in distilled water. In addition, ethanol solutions had no effect on TEGDMA elution.
The release of TEGDMA monomer was determined by comparing the time-dependent elution of the compound with that of the reference compound. The release of TEGDMA monomer was highest after 14 days in ethanol and distilled water, while the release of UDMA and BisGMA were lowest at 3 and 7 days, respectively. However, the monomer release decreased as time passed, with the highest concentrations detected at 96 h and 75% ethanol.
It is less prone to shrinkage stress
Low-shrinkage composite resins for tooth restorations have some important advantages over conventional resins. This type of resin exhibits less shrinkage stress and strain while retaining 韓国歯科 its mechanical properties. Another benefit of low-shrinkage composites is their biocompatibility. Furthermore, they tend to have better adhesion and provide a more resistant seal. However, further research is needed to evaluate the effectiveness of these low-shrinkage resins in reducing cusp deflection, microleakage, and stress.
Despite the advantages, tooth resins are subject to polymerization-induced shrinkage. This shrinkage stresses dental restorations. The present review provides updated information on the causes of shrinkage, techniques for measuring shrinkage, and strategies to control shrinkage. In addition, the authors discuss the latest research on bio-active nanocomposite for dental restorations. These composites reduce secondary caries, increase restoration longevity, and maintain oral health.
It is less stain-resistant
Tooth resin is not as stain-resistant as tooth enamel and is susceptible to stains. Unlike natural tooth enamel, this resin can be easily chipped or worn away if certain substances are ingested or if the patient bites down on hard food. To keep your bonding in good condition, you should avoid smoking and drinking caffeinated beverages as these substances can damage your bonding.
In addition to the above factors, some dental materials are prone to staining. This makes certain dental restorations less stain-resistant. For example, composite resin is prone to stains when regularly exposed to foods and drinks with colored pigments. These foods and beverages include red wine and coffee. In addition, these types of substances can react with teeth whitening products differently. This is a concern for people who have bonding work done.
It is easier to apply韓国歯科
The process of applying tooth resin is a simple procedure that can be completed in a few hours. The dentist will place the resin on the tooth and then use a special light to harden it. Once the resin is hardened, Dr. Sheppard will then sculpt the resin to the desired shape and polish the area. The process typically takes about 30 minutes per tooth. The process may take a few days for some patients, but they should be able to resume normal activities immediately after the appointment.
Teeth resin is easy to apply because it is made of a putty-like substance that is able to fit in the right shape. The dentist will use a conditioning gel before applying the resin, which will help it adhere to the tooth. There is no need for anesthesia for a surface repair, but local anesthesia is necessary for procedures near a nerve. Once the resin has been applied to the tooth, the dentist will apply a final coating that will make it more durable and last longer.
