Abstract
Strojna endodoncija i NiTi instrumenti postaju zlatni standard dobre endodontske prakse. Obitelj NiTi endodontskih instrumenata za strojnu endodonciju, od prije 2 godine, bogatija je za još jedan sustav Twisted File (TF) (Sybronendo, Orange USA). TF instrumenti izrađuju se revolucionarnim načinom uvijanja što do sada proizvođačima nije polazilo za rukom. Proces izrade se temelji na naizmeničnom grijanju, hlađenju te uvijanju nikal-titanske žice u R fazi kristalne rešetke nikal-titanske legure. U ovom radu je prikazana je i objašnjena tehnika izrade te detaljan protokol uporabe TF instrumenta iz dostupnih informacija od strane proizvođača te iz aktualne dostupne znanstvene literature. Prikazano je 5 kliničkih slučajeva pacijenata obrađenih na studentskim vježbama. Od ukupnog broja slučajeva obrađeno je ˝Step back˝ tehnikom čeličnim instrumentima izrađenim po ISO standardu 2 slučaja, a TF instrumentima 3 slučaja. U testiranim uvjetima korištenja, od strane studenata s ograničenom endodontskim iskustvom, TF endodontski sustav je pokazao, uz jednostavnost upotrebe, predvidljive i pouzdane rezultate endodontske terapije. Nije došlo ni do jednog puknuća, a niti oštećenja instrumenata. TF sustav je vrijedan novi član NiTi obitelji endodontskih instrumenata za strojnu obradu korijenskih kanala čija će primjena sigurno značajno rasti, kako u krugu specijalista endodoncije, tako i u krugu općih doktora dentalne medicine.

Engine driven endodontics and NiTi instruments are becoming a golden standard of good endodontic practice. The NiTi instruments family for engine driven endodontics, since 2 years, becomes richer for new instrument set: Twisted File (TF) (Sybronendo, Orange USA). TF instruments are manufactured by revolutionary twisting process that no manufacturer managed to accomplish, till now. TF instruments are produced by alternately heating and cooling the wires and twisting them in the R phase of the NiTi crystal grid. The manufacturing technique and the clinical application protocol are presented through manufacturer provided information and the present scientific data in the literature. Five clinical cases treated at the student clinical exercises are presented here. From the total cases presented, two were performed with standard stainless steel hand instruments with “Step Back” technique, and tree with TF. In the tested application conditions, in the hands of the students with limited endodontics experience, the use of TF files was, beside simplicity of use, reliable and predictable. No fracture or damage of the used instruments was noted. TF instruments are a valuable newcomer the family of engine driven NiTi instruments and for sure its application frequency will grow in the general practitioner dentists and endodontis specialists.
