Angelus Reforpost Mix Carbon Fiber Post - Refill

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

• Great mechanical properties
• Allows radiographic visualization
• Lower risk of root fracture
• Less tissue removal in apical third of root canal
• Great retention
• Saves clinical time and decreases lab costs
• Easy removal 

REFILL-5 POSTS 

• TECHNIQUE OF USE
  A. ROOT CANAL PREPARATION
  
• Select the pin using the template and the periapical x-ray of the
  tooth
  
• Remove some of the root canal filling 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
  filling at the root apex due to the presence of accessory canals,
  which must remain sealed to prevent bacterial contamination
  
  
• Prepare the canal with the drill corresponding to the diameter of
  the selected post
  B. PREPARATION OF REFORPOST FOR CEMENTATION
  
• 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 fibers changes the
  mechanical properties of the pin;
  
• Clean the post with alcohol and dry it ;
  
• Apply a layer of silane (SILANO ANGELUS®) and let it dry for 1 minute

Question: WHAT IS THE DIFFERENCE BETWEEN A CARBON FIBER PIN AND A FIBERGLASS PIN?
Answer: The carbon fiber pin is black in color and currently has the same mechanical strength as a glass fiber pin (1200 Mpa).

Question: WHAT DRILLS SHOULD BE USED WITH REFORPOST CARBON 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 CARBON 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.

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: It’s 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 CARBON fiber posts, self (chemically)-cured only resin cements are the best recommendation.
