MicroSeal systems and modified technique.

Abstract

The MicroSeal technique was introduced in 1996 and consists of a nickel-titanium (NiTi) spreader, a NiTi condenser, a gutta percha heater, a gutta percha syringe, and a special formulation of gutta percha available in cones or in cartridges. It is considered a thermomechanical compaction technique that uses a rotary instrument to plasticize the gutta percha and move it within the root canal apically and laterally. The MicroSeal technique together with the author's modifications may be a very important tool in the hands of the endodontist. The MicroSeal system is able to preserve a conservative preparation and provide an adequate penetration by the obturation instruments in the apical third. Knowledge of the technique's indications and limitations represents an important step in the learning curve for those practitioners who are willing to incorporate a new obturation method into their clinical techniques.
