refers to the present utility model patent for a "dual slot skeletal anchor breaker" device. whose model differs from the models referred to in patent application br 10 2016 007772 9 and utility model br 20 2016 030737 1, filed on 07/04/2016 and 28/12/2016, respectively. the modification referred to in this utility model patent with respect to the original patent application process br 10 2016 007772 9 and the utility model patent application process br 20 2016 030737 1 is the modification of the through holes (5) in the original application and the through slots (5) in the utility model patent application br 20 2016 030737 1. thus the device in question two-slot skeletal anchor breaker (1) and reason for this application utility model patent, presents as a technical novelty in relation to the original application patent application br 10 2016 007772 9 and the utility model patent application br 20 2016 030737 1, of the same device, two slots (channels) (5) for insertion of two mini-implants instead of four, as in the above patent applications above. This patent application for the two-slot skeletal anchor breaker device (1) also has the technical feature of being able to install the two mini-implants in the slots of the device, inclined up to 45º. also the number of positioning rods (6) goes from four rods in the previous models to two rods in the model in question with two-slot skeletal anchor breaker (1). This device is indicated for use in children aged 9 to 13 years, at puberty, when bone density in the anterior palate already allows the use of mini-implants for skeletal anchorage of the circuit breaker for rapid maxillary expansion. In this case, only two slanted inserted mini-implants in the premaxilla region behind the 3rd palatal crease are sufficient and sufficient for the opening of the midpalatal suture in its rapid expansion assisted by mini-implants - marpe -.refere-se a presente patente de modelo de utilidade a um dispositivo ?disjuntor de ancoragem e
