Itena Dentolic (Glass-Fiber Post) Refills

Elasticity modulus similar to dentine

Favourable constraint: deformation ratio for the tooth. Homogenous distribution of mechanical constraints

“In fact teeth restored using glass-fiber posts result in only a small number of failures, which are often repairable. In contrast, teeth restored using metal posts commonly present with more significant fractures, often resulting in the loss of the tooth.“ (Standlee, 1988; Freeman, 1998)

• Chemical retention between the core build-up and the glass-fiber post (mechanical retention only in a steel post procedure)
• Perfect aesthetic result
• Radiopacity
• No toxicities: biocompatible
• No risk of corrosion, or tissue discoloration
• Reamers from the DentoClic range

Hints and Tips

• To increase chemical interaction at the glass-fiber/bonding interface, apply silane to the surface of the post and dry thoroughly before applying bonding

• How to remove a glass-fiber postIn comparison to other systems such as inlay-core, the clinical value of this type of restoration lies within the ease of such removal procedures.
1. Remove the composite in order to gain access to the relevant post.
2. Make an initial hole at the location of the insert without water to it.
3. Use either a diamond-tipped, sonic or ultra-sonic insert without water, or a suitable drill, to delaminate the fiber and reveal the canal under the restoration.
