FibreKleer 4X Tapered Fiber Post Kit (15 posts + 3 drills+ box)

Instructions for use of FibreKleer 4X

Preparation of the canal:

1. To ensure that as much as possible of the cervical structure of the tooth is preserved, choose an insert with a diameter slightly wider than the diameter of the filled canal around the tooth neck.
2. Using a drill, determine the depth of preparation for the post, leaving at least 4mm of filling material – gutters at the tip. Place a rubber stop on the drill bit corresponding to the planned depth under the insert. The inlay must extend 3-5mm apical to the ridge bone, keeping the 4mm (minimum) filling of the canal at the apex.
3. Use a heating instrument to remove the filler material to the desired sub-insert depth.
4. Using the FibreKleer or FibreKor drill bits, work out the canal so that the insert fits perfectly.
5. Rinse the channel to remove debris and dry with air and paper points.
6. Try the FibreKleer insert in the canal of the same size as the last drill was used. To check if the insert is properly seated, you can take an x-ray.
7. FibreKleer 4X Post must be cut with a separator or diamond drill with a water-cooled turbine tip. Rotate the insert while cutting to achieve a smooth cut surface. To preserve the retention head, the cut -off of the FibreKleer 4X Parallel Posts should be done from the apex side. FibreKleer 4X Tapered Posts should be cut from the occlusal side to preserve the apical taper.
8. Clean the element by wiping with alcohol and drying it with oil-free air.

Cementing of posts

– If Total Digestion is preferred:

1. Etch the canal with 37% phosphoric acid for 20 seconds.
2. Rinse the canal thoroughly and dry using paper points. Leave the dentin slightly moist.
3. Apply Bond-1 Primer / Adhesive to the inside of the canal using a syringe or microbrush. If microbrush is used, duplicate or multiple applications are required. Gently dry the canal with oil-free air and remove excess resin from the canal using paper points. Don’t irradiate. Please see the instructions for use of Bond-1 Primer / Adhesive.
4. Introduce Cement-It Universal C&B or Build-It FR into the root canal using the root canal filling tool or directly with a self-stirring paddle.
5. Coat the post with Cement-It Universal C&B or Build-It FR cement and insert the post into the channel with a slight finger pressure, allowing excess cement to drain out. Remove excess cement with a plastic instrument. Please see the working and setting time of cement and core build-up material in the instructions for use of these materials.

– If the self-etch technique is preferred:

1. Introduce the Breeze Self-Etching Cement into the prepared canal using a self-stirring intraoral stirrer.
2. Cover the post with Breeze cement and insert the post into the canal with light pressure with your finger, allowing excess cement to drain. Remove excess cement with a plastic instrument. Please see the working and setting time of Breeze cement in the instructions for use. Pay attention to the amount of time it takes for self-digestion.
3. Initiate light setting of double-curing cement or core build-up material by irradiating from above for 10 seconds. See working and setting times in the instructions for use of Breeze , Cement-It Universal C&B or Build-It FR .
4. Using Build-It® Core Forms , build the core with Build-It FR dual material or Build-It Light Cure light curing
5. Using diamond and carbon drill bits, shape the cured core build-up material as required by the final restoration.

Contraindications:

• FibreKleer 4X posts are contraindicated in teeth with less than 2mm of the crown structure above the alveolar bone
• The cementation of FibreKleer 4X with glass ionomers, zinc phosphate or polycarboxylic cements is contraindicated.
