[Micro Apical Placement System (MAPS) . A new instrument for retrograde root filling].
A retrograde radicular preparation in the axis of the root canal as well as an excess-free obturation of the canal is surgically very demanding due to the complex anatomical structures and to the limited intraoral operative field. As from the early 1990s, advisable methods for the retrograde root canal obturation under minimal place requirements have been implemented thanks to ultrasonic- and sonic-driven microinstruments. This publication presents a new microsurgical instrument, the "Surgical-Retro" Micro Apical Placement System (MAPS), which facilitates in a large extent the retrograde obturation with a plas tic root canal filling material. The device provides an unrestricted access to the retrograde cavity, allowing thus an accurate obturating technique whilst avoiding the dispersion of the root canal filling material in the surrounding bone. Thanks to the "Surgical-Retro" Micro Apical Placement System, a further gap in the improvement of the quality and, thus, of the success of the treatment by apical resection has been filled.
