Description
ADVANTAGES
- The Jen-Esthe Posts are made of transparent quartz fibers bonded with a high-strength epoxy under pressure.
- The Jen-Esthe Posts have elasticity and thermal expansion indexes similar to the parameters of tooth dentin.
- The refractive indexes of epoxy resin and quartz fibers are carefully chosen and are very close, thus allowing the post to be amazingly masked in composite materials
- The Jen-Esthe Posts create high-strength compound with a composite material and provide superior aesthetic restorations, i.e. do not need masking, one must mask the darker end portion of the post only. Thanks to transparency of the Jen-Esthe posts, the light cure can be carried deep in the canal (“light guide effect”).
- Unlike posts of other manufacturers with cone ends, the end of the Jen-Esthe Post has a special hemispherical shape. This prevents excessive concentration of stress in the tooth root: while the tapered end of the pin acts as a wedge, i.e. under load there is a stress directed to split the tooth root, a post with a spherical end optimally
- Do not require specific treatment before placement.
