Exacto Translucent Posts are glass fibre intraradicular conical posts indicated for support of restorations and prosthetic crowns. When dentin conservation is a must, the anatomically shaped, small size 0 Exacto Post is the right choice. Exacto Post is 80% filled with Glass fibres. These innovative fibres, in combination with an appropriate polymer matrix, add excellent translucency to the post and highly attractive aesthetic properties to the final restoration.
Excellent Radiopacity and Flexural strength, with a modulus of elasticity close to that of dentin. The two taper shape allows for smaller conservative canal design while preserving the true tooth anatomy. Other features and benefits include:
- Post size follows root canal anatomy
- Popular 0.5 size for small canals and for maximum retention of tooth structure
- Double taper - matches root canal shape
- Special glass fibre - high esthetics and strength
- Excellent transmission of light
- High concentration of fibres - better mechanical properties
- Greater radiopacity allows radiographic visualization
- Modulus of elasticity similar to dentin's lower risk of root fracture
- Silicone stop identifies post size and indicates place for cutting
- Direct use (prefabricated) - saves clinical time and decreases lab costs
- Longitudinal fibres - easy removal
- Versatile sizes - indicated for most clinical cases
Application Technique:
-
Use Heated Instruments to Remove Two-Thirds of the canal filling.
-
Prepare the canal with the exacto drill. To verify the predation, take a periapical radiograph.
-
Position the post in the canal to ensure proper fit and complete insertion.
-
Trim the post to the desired height.
-
Use water jets to rinse the canal then use air and absorbent paper tips to dry it.
-
If required, apply acid etching the canal for 15 seconds with a 35% self limiting etch such as Ultra-Etch.
Step 6B: If you are using a corebuild up that need Bond and/ or primer – please refer to the manufacturers instructions. If you use Cosmecore you can skip this step.
-
Clean the post with alcohol. Dry with air.
-
Post is place through Cosmecore material which has been injected into the post and canal space.
-
After Light-Curing, tooth is ready for final preparation. CosmeCore will not affect the shade of the restoration.
Follow a case of a single cone obturation technique and the installation of an intraradicular post in a single session.

Q: What is the advantage of a conical post?
A: Precise adaptation to root canal: the post shape follows the canal anatomy.
Q: Why do conical posts need specific burs / drills?
A: Because the adaptation must be precise according to the root canal, otherwise there may be a lack of retention due to the conical shape of the post. All conical posts require standardized burs.
Q: What is the purpose of the latex ring placed on Exacto?
A: To show the site for cutting the post and, because of the association of their colors with those of the burs, to allow identification of the correct bur.
