The 3M ESPE Filtek Z350 XT Universal Restorative Syringe Kit is a dental composite designed for both anterior and posterior restorations. This restorative kit is offered in Dentin, Body, Enamel, and Translucent shades, all packaged in syringes and single-dose capsules. Each shade is radiopaque. Included in the kit is a dental adhesive that ensures a permanent bond between the restoration and the tooth structure.
Technical
The Filtek Z350 XT Universal and Flowable Restorative products from 3M ESPE utilize nanotechnology, featuring several distinctive properties:
· The presence of bonded nanofillers in the Filtek Z350 XT restorative dental kit contributes to its exceptional polish retention.
· The polish retention of the Filtek Z350 XT restorative is superior due to the patented method employed in the creation of the nanocomposite, outperforming other composites and microfills.
· In-vitro laboratory studies indicate that the wear resistance of the Filtek ™ Z350 XT restorative is on par with that of the Filtek ™ XT restorative, instilling confidence for use throughout the mouth.
· The application of true nanotechnology in the formulation of the Filtek Z350 XT nanofiller flowable dental restorative kit results in wear resistance comparable to that of enamel.
· A five-year clinical study has demonstrated that there is no statistically significant difference between the Filtek ™ Z350 XT Universal Restorative and natural enamel.
The restoration preserves a smoother surface, ensuring that the initial high gloss remains intact for years, thanks to the formation of unique clusters of nanometer-sized particles. This is due to the fact that the nanoclusters wear at a rate similar to that of the surrounding resin matrix during abrasion.
