Micro-Mega also offers optional using apical finishing files. These sterile single-use NiTi-finishing files are used after root canal shaping with One Shape in order to enlarge the root canal diameter.
The Revo-S NiTi rotary system also manufactured by Micro-Mega simplifies and optimizes the cleaning and shaping of the root canals with only three NiTi instruments. The asymmetric cross section of the Revo-S facilitates penetration by a snake-like movement and offers a root canal shaping adopted to the biological and ergonomic imperatives[ Figure 1 ].
Single-file rotary systems are classified to two groups: continuous rotating and reciprocating files, based on type of their motions. This perfect combination of flexibility and fracture resistance makes it possible to reduce the number of files required for cleaning and shaping during root canal treatment without having to dismiss preservation of the original curve and anatomy of the root canal.
HyFlex EDM offers the dental clinician such an ease of mechanical preparation of the root canal system that even newcomers to endodontics can achieve reliable results easily and quickly. The EDM process produces a file that is extremely flexible and also fracture resistant. Regarding the CM properties, HyFlex EDM files preserve the original anatomy of the canal, which significantly reduces the risk of ledging, canal Transportation and perforation.
The optimum flexibility, cutting efficiency and separation resistance of the HyFlex EDM make it possible to reduce the number of files required for cleaning and shaping while preserving original anatomy.
The XP-endo shaper is a truly innovative shaping instrument which can radically simplify endodontic sequences. This system uses a hollow NiTi file, without a central metal core, through which a continuous flow of irrigation is provided throughout the procedure.
The SAF technology offers effective cleaning of all root canal variations such as oval canals and provides the effective disinfection and shaping of all canal morphologies. This system uses a new technology of cleaning and shaping in which a uniform layer of dentin is removed from the entire perimeter of the root canal and avoids unnecessary and excessive removal of intact dentin [ Figure 5 ].
One Curve is a single-use, heat-treated NiTi rotary file that enables shaping of the full length of the canal with a single instrument, directly to the apex. The advantages of One Curve, single-file technology are listed below:.
Increased blade flexibility and more separation resistance resulted from C. Perfect taper and diameter for a final shaping that meets standards of an optimized cleaning and shaping. Preserves the original anatomy of the root canal [ Figure 6 ]. Today, the single-file NiTi rotary systems have highly improved the quality of canal shaping along with saving the time for both the clinicians and the patients.

Abstract Over the past two decades, the nickel—titanium NiTi rotary instruments have highly improved the quality of the cleaning and shaping of the root canals. Open in a separate window. Figure 1. When instrumentation was continued to size 40 apically with step-back, there were no significant differences in transportation in the apical or coronal sections.
However, during instrumentation to size 40 with step-back, the combination of modified tip and nickel-titanium alloy produced significantly more transportation and dentin removal, as well as greater deviation from the center at the mid-root level than did other file designs. Thus, of the file design parameters evaluated in this study, construction from nickel-titanium was most important in defining canal configuration at small file sizes in the apical region. The incidence of other procedural errors was also significantly reduced by the use of nickel-titanium hand files.
Abstract Straightening of curved canals is one of the most common procedural errors in endodontic instrumentation. Substances titanium nickelide Stainless Steel Nickel Titanium.
