Glass fiber intraradicular conical post.
Support of restorations and prosthetic crowns
|Features||Greater radiopacity: allows radiographic visualization Standardized burs with inactive tip: precise calibration of posts according to burs present in the kit; very thin cement layer High concentration of fibers: better mechanical properties Special glass fiber: excellent transmission of light Double taper: matches root canal shape 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 fibers: easy removal Versatility of sizes: indicated for most clinical cases|
PRECAUTIONS: Use of direct cores with fiber posts is not indicated for extensive oral rehabilitation in patients with parafunctional habits Use of the direct core with fiber post should only be indicated to teeth with a minimum height of 2 mm of coronal dentin EXACTO should only be cut with diamond burs on high speed under water cooling. Scissors and pliers cannot be used. Use eye protection and a mask to avoid inhalation of particles Fiber posts must be completely covered by the cementing agent or the composite resin. Exposed fibers absorb water which deteriorates the mechanical properties of the posts.
|Directions To USE|
DIRECTIONS FOR USE A. ROOT CANAL PREPARATION 1. Select the pin using the template and the periapical x-ray of the tooth 2. Remove part of the root canal filling with heated instruments according to the predetermined depth. Leave at least 3 to 5 mm of obturation in the root apex due to the presence of accessories canals 3. Prepare the root canal with the matching drill of the selected post EXACTO 0.5 - Drill 0.5 (purple) / EXACTO 1 - Drill 1 (white) / EXACTO 2 - Drill 2 (yellow) / EXACTO 3 - Drill 3 (blue) 4. Take a periapical radiograph to check the root canal preparation and filling. Excessive removal of gutta-percha may lead to endodontic failures B. PREPARATION OF EXACTO FOR CEMENTATION 1. Check insertion and position of the post in root canal. Slide the post stop towards the area chosen for cutting (at least 2 mm from the opposing tooth occlusal surface) (2. EXACTO should only be cut with diamond burs on high speed under water irrigation. Pliers and scissors should not be used: smashing of post leads to loss of its mechanical properties 3. Clean EXACTO with alcohol and dry with air . And apply a silane agent (SILANO ANGELUS®) and let it dry for 1 minute 4. Apply the chemical adhesive FUSION-DURALINK® CATALYST ANGELUS® according its instructions C. CEMENTATION 1. Wash the root canal with an air/water spray and dry with air and absorbent paper points 2. Etch the root canal for 15 seconds with 37% PHOSPHORIC ACID ANGELUS® 3. Wash the root canal and dry with air and absorbent paper points Apply primer FUSION-DURALINK® ANGELUS® and wait 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 fill the conduit. 6. Insert the post in the canal, remove the excess of cement and wait for its polymerization. If the resin cement is dual-cured, light-cure it now . L Zinc-phosphate and glass ionomers (conventional and resin-modified) may also be used for the cementation of posts, but their properties are inferior to those of composite resin cements. Auto-adhesive cements eliminate the needs for the steps of acid conditioning and adhesive application. D. BUILDING THE CORE (CORONAL PART) 1. Build the core with a restorative composite resin (hybrid, microhybrid or any specific composite resin for cores) or with REFORCORE® ANGELUS®. REFORCORE® is a prefabricated glass fiber core, specially developed for the technique of direct posts
