Angelus Reforpost Fibre Glass - Refill

• Parallel shape with grooves: great retention
• Metal filament: allows radiographic visualization
• Longitudinal fibers: easy removal
• For use with Peeso (Largo) drills: easy to adapt
• High concentration of fibers: great mechanical properties
• Modulus of elasticity similar to dentin´s: lower risk of root fracture
• Conical tip: less tissue removal in apical third of root canal
• Direct use (prefabricated): saves clinical time and decreases lab costs

A. ROOT CANAL PREPARATION

1. Select the pin using the template and the periapical x-ray of the tooth

2. Remove some of the root canal fi lling with heated instruments to the predetermined depth. The use of drills can cause apical displacement of the gutta-percha. Allow at least 3 to 5 mm of fi lling at the root apex due to the presence of accessory canals, which must remain sealed to prevent bacterial contamination

3. Prepare the canal with the drill corresponding to the diameter of the selected post

B. PREPARATION OF REFORPOST FOR CEMENTATION

1. Position the pin to verify its adaptation. Make a mark on the pin 2 to 3 mm from the antaonist tooth – and cut it with a diamond bit at high rotation under cooling. Do not use scissors or pliers, because the maceration of the fi bers changes the mechanical properties of the pin

2. Clean the post with alcohol and dry it

3. Apply a layer of silane (SILANO ANGELUS®) and let it dry for 1 minute

 WARNING: It is not necessary to apply the silane on REFORPOST® CARBON FIBER

4. Apply the ANGELUS® FUSION-DURALINK® CATALYST to the post according to its instructions

C. CEMENTATION

1. Clean the canal with the air-water spray and dry it with air and absorbent paper points

2. Etch the canal with ANGELUS® 37% PHOSPHORIC ACID for 15 seconds

3. Wash again the canal and dry it with air and absorbent paper points Apply ANGELUS® FUSION-DURALINK® PRIMER in the canal and wait for 1 minute

4. Apply ANGELUS® FUSION-DURALINK® CATALYST according to the instructions. The adhesive components must not be mixed before application. They are polymerized chemically without light curing

5. Spatulate the resinous cement selected* and fi ll the conduit

6. Put the post in the canal, remove excess of the cement and wait for the polymerization. If the cement is dual, light cure it  Zinc phosphate and glass ionomer cements (conventional and resin-modifi ed) can also be used, but their mechanical properties are inferior to those of the resin cements. Auto-adhesive cements eliminate the needs for the steps of acid conditioning and adhesive application

D. CROWN BUILD-UP

1. Do another etching with ANGELUS® 37% PHOSPHORIC ACID and apply an adhesive on the remaining tooth structures and post. Build the crown core with composite resin, or with ANGELUS® REFORCORE®. REFORCORE® is a prefabricated glass fi ber core, for the technique of direct cores

E. USE OF ACCESSORY POSTS IN WEAKENED ROOTS AND WIDE CANALS

1. Fill the remaining spaces of the canal with ANGELUS® REFORPIN® accessory posts. The decrease in thickness of the cement and the better retention provided by REFORPIN® reduce the risk of post/core loosening

Question: Which size is mostly recommended for central incisors?
Answer: For central incisors, it is typically recommended to use sizer 2 or 3 of the Angelus Reforpost Fibre Glass - Refill. These sizes are optimal for accommodating the wider canals commonly found in central incisors, ensuring a secure and properly fitted post for effective restorative treatment.

Question: What is size #1 diameter size?
Answer: The Angelus Reforpost Fibre Glass Refill offers a range of sizes to accommodate diverse dental needs. In Size 1, with a diameter of 1.1mm and a length of 20mm, it harmonizes with largo drills no. 3, ensuring precise and stable post placement. Size 2, featuring a 1.3mm diameter and the same length, aligns seamlessly with largo drills no. 4, providing increased diameter for enhanced stability. Finally, Size 3, with a 1.5mm diameter and 20mm length, is tailored for largo drills no. 5, offering a robust solution for reliable post placement in dental procedures.

Question: WHAT IS THE ADVANTAGE OF A POST WITH A CONICAL TIP?
Answer: The parallel-sided shape of Reforpost favors its mechanical interlocking with the root canal walls. Its conical tip allows less tooth reparation at the apical third, saving dentin in this area.

Question: WHAT DRILLS SHOULD BE USED WITH REFORPOST GLASS FIBER?
Answer: Post 1 – Largo drill number 3Post 2 – Largo drill number 4Post 3 – Largo drill number 5.

Question: WHAT ARE THE STEPS FOR THE CEMENTATION OF REFORPOST GLASS FIBER?
Answer: Post preparation: clean with alcohol, apply silane (Silano – Angelus) for 1 minute, apply the adhesive. Root canal: acid-etch (37% phosphoric acid for 30 seconds), wash with water, dry with absorbent paper points, apply the primer, apply the adhesive, place Reforpost with resin cement (Cement Post – Angelus).

Question: WHAT IS THE ADVANTAGE OF A SERRATED POST?
Answer: The undercuts increase the retention of the post with the cement.

Question: WHY DOES REFORPOST 1 HAVE A SMOOTH MIDDLE PART, WITHOUT UNDERCUTS?
Answer: Its thinner diameter and, consequently, less fiber, could render Reforpost 1 more fragile. So its middle part is smooth, thicker and stronger.

Question: WHAT CEMENT SHOULD BE USED WITH REFORPOST?
Answer: For the cementation of glass fiber posts, self (chemically) – cured only resin cements(Cement Post – Angelus) are the best recommendation.
