Angelus Exacto - Intraradicular conical post
Precise adaptation to the canal
The double taper and the special size enable the Exacto post to fill tapered canals
more accurately, without leaving a thick line of cement.
Standardized bur with inactive tip
Exacto burs exactly reproduce the diameter of the post and do not have an active tip, avoiding the risk of accidental perforations.
Special size
Exacto posts have a smaller size (17 mm), so they can fill the canal entirely with their taper, avoiding spaces that can lead to future displacement of the post
Identification colors on the post and on the bur
To facilitate use and avoid possible errors in preparation
Delimiting cursor
The latex ring helps in delimitation of the cutting area, as well as identifying the numbering of the post:
Optimal Translucency
Exacto posts have the translucency needed for the favorable aesthetic reproduction of the restorations. The use of innovative fibers in combination with an appropriate polymer matrix confers translucency to the post and highly attractive aesthetic properties to the final restoration
Benefits
- Allows radiographic visualization
- Precise calibration of posts according to burs present in the kit. Very thin cement layer
- Better mechanical properties
- Excellent transmission of light
- Matches root canal shape
- Lower risk of root fracture
- Identifies post size and indicates place for cutting
- Saves clinical time and decreases lab costs
- Easy removal
- Indicated for most clinical case
Time and cost saving
The technique of making prosthesis with pre-fabricated Fiber/Metal posts allows for creation of the post/core in a single session, eliminating steps and laboratory costs
Modulus of elasticity - 30-40 Gpa
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 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 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. 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
