What is Thermafil made of?

What is Thermafil made of?

The “Thermafil” is a patented endodontic obturator consisting of flexible central carrier made of stainless steel, titanium, or plastic uniformly coated with a layer of α-phase gutta-percha (8). When heated the gutta-percha becomes thermoplasticized and adheres to the carrier.

Why do we Obturate root canal?

Root canal obturation is necessary when the pulp tissue is removed from the root canal system leaving a dead space that can be recolonized by microorganisms. After pulp removal, the root canal is cleaned, shaped, and irrigated after which it is obturated.

What is a Therma fill?

Thermaflow™ Thermal Fill Thermaflow is a range of thermally conductive concrete mixes that both conduct and transfer the considerable heat generated by buried electric cables. Its performance is pre-tested and third party verified for optimized data center duct bank design.

How do I uninstall gutta-percha carrier?

Chloroform rapidly softens gutta percha and, in conjunction with files, allows for the removal of gutta percha in a crown-down manner. With the canals filled with chloroform bath then paper points are utilized to wick residual gutta percha and sealers from the more inaccessible regions of the root canal system.

What are obturation techniques?

What The Term “Obturation” Means in Endodontics. Dentists who perform fillings, root canal procedures, and other restorative methods of filling a tooth have to be skilled in obturation. Obturation is the technical term for a method of filling and sealing a tooth with root canal material.

Do you need sealer with Guttacore?

The armamentarium for GuttaCore obturation is comprised of a pre-selected size verifier and CBO, and a heating oven (Figure 4). Additionally, sealer is essential, is a critical lubri- cant, and should be compatible with any warm gutta percha technique.

Does gutta-percha dissolve?

At 5-minute immersion time interval, xylene displayed the best dissolving efficacy in dissolving gutta-percha followed by refined orange oil and tetrachloroethylene in descending order. At 5-minute immersion time interval, all of the test solvents exhibited the same dissolving capacity in dissolving resilon.

Can gutta-percha be removed?

Removal of gutta percha (GP) is a critical step in endodontic retreatment. Removal of GP is generally accomplished by the use of heat, Hedstrom files, GP solvents, and rotary GP removal instruments.

What material is used for the obturation of a canal?

While other materials are available for obturating root canals, gutta percha is still the most widely used and accepted material. Gutta perch is biocompatible, inert material which does not irritate tissues.

How do you do obturation in RCT?

Summary of the Root Canal Obturation Technique

1. Dry the canals by inserting paper points cut to the root canal working length.
2. Fit a standardized gutta-percha point to the established root canal working length, which is 1 mm short of the root canal length.
3. Check the fit of the gutta-percha point in a radiograph.

How does the Thermafil system work?

Two transverse grooves along the stem allow depth control. Being used dry, the heat produced by the friction can quickly remove both the carrier and gutta-percha to the desired depth. The sequence to achieve a perfect root canal filling with the Thermafil systematic will be described below:

Where should the Thermafil obturator be cut?

The Thermafil Obturator should be cut at the canal orifice. The Thermafil system is one of the more predictable and effective methods to obtain a correct filling of the complex three-dimensional root canal system, and is one of the few that allows to convey warm gutta percha directly at the apex.

What are Thermafil plastic carriers made of?

Note the minimal invasive approach of this technique (when it is applicable). Thermafil plastic carriers (Figure 1) are made of a radiopaque polymer of polysulfone and are available with a tip diameter from 0.20 mm up to 1.40 mm.

How is α phase gutta-percha used in root canal treatment?

Initially, this system relied on metallic carriers covered by a uniform layer of α phase gutta-percha, intended to be heated over an open flame and inserted in the root canal, already dried and treated with a small amount of sealer.
