How One-Step Obturator™
How to use the One-Step Obturator™ - step by step
|Before you start||Step 1||Step 2|
|A properly cleaned and shaped canal
A rinsed and desinfected root cananl - N.B. the best way to obtain this is using FotoSan®
A defined wotking length
A dry root canal
|Confirm the selected obturaror size by inserting the matching size verifier into the canal to the working distance. A slightly loose fit in the apical third is critical to allow clearance for back-filling of the gutta percha. A tight fit may prevent the obturator from seating to the working distance.
N.B. When using a rotating filesystem with a taper 0.04 or more you do not need to use a size verifier. Use the same size obturator as the last used size file.
|Place a thin coating of sealer on the wall of the canal.
Avoid using too much sealer. It is possible to extrude sealer periapically, when you use too much, Use a paper point to remove excess sealer.
The obturator is heated in the oven and inserted into the canal to working length. Use the rubber stopper as an indicator.
|Step 3||Technique tips||Post prep preparation|
|1. Use the Size Verifier to place a thin coating of sealer on the wall of the canal.
2. Confirm the selected obturaror size by inserting the matching size verifier into the canal to the working distance.
3. Fill the smallest canal first.
4. When filling a multi rooted canal, place paperpoints in the other canalls to avoid excess guttapercha from the pulp chamber to enter the canals.
|When the gutta percha is set for 3-4 minuts and take a grip on the shaft where you want to break it.
You can trimm the plastic core with the CoreRemover burr.
|The end result is a perfectly sealed canal.
We recommend that you take a control xray
|If you need to place a post the plastic core can easily be removed with the Core Remover burr. The CoreRemover burr, is a smooth burr with no cutting edges. The technique is working with frictional heat.
The advantage of the CoreRemover is that it does not loosen the obturator and you do not risk a perforation.
