NEW ROTARY MECHANICAL SYSTEMS THAT USE NI-TI NEEDLES AND THE CROWN-DOWN TECHNIQUE IN ORDER TO PREPARE THE ROOT CHANNELS
Abstract:
The preparation of root channels is important in the endodontic treatment which aims at processing the endodontic space with the purpose of accomplishing the medicinal treatment and root filling from the pulp-periodontal infected teeth. Today, within the Crown-Down technique, it is recommended to use the rotary mechanical systems which use endodontic needles made up of Ni-Ti, such as: Profile System (Maillofer), Hero System (Micr-Mega), and the Tri-Auto ZK System (Morita). Regarding the major advantages in using these systems, we can mention: a technique easy to be learnt by the practitioner, high precision system technology, and minimum risk regarding possible therapeutic failures.
