The dental enlarger consists of a Pentagon (1) a two-stage long base (2) a cylindrical cylinder and a three-stage balance arm (3), which is modified in the form of a bellows in the third stage (29 The modified high resistance coil (4) is a hook up mechanism, which can be coupled and separated with reference to the lens (10) during the whole head movement.Enlarge the macro (7) and the camera (11). This addition will serve as a mechanism to exchange the top of the head, as a safety method, close the top of the head as a whole, and complete the operator's attention program,And the practice of balancing the arms by separating the head as a whole (3), which facilitates transport without cumbersome armed and disarmament procedures. Since it is impossible to change the head of the microscope (10) from the structure to the position of ethnology, it is decided to adjust a high resistance rotor (4) to tilt the head of the microscope (10) to produce the ethnology required by the operator, In addition, the modification made in the high friction ring (4) reduces the number of circles described to be allowed to remain in the work area during head rotation.Dispositivo de magnificacion para uso odontologico que comprende una base metalica pentagonal (1) un pedestal (2) cilindrico alargado de dos segmentos y un brazo compensado (3) de tres segmentos, este brazo compensado (3) lleva una modificacion en forma de rielera (29b) en el tercer segmento (29) que afrontado al artilugio de prensa (30) propio de la rotula de alta friccion modificada (4) conforman el mecanismo de enganche que permite el acople y desacople en un solo movimiento del cabezal como un todo, haciendo referencia al cabezal de microscopio (10), al zoom macro (7) y a la camara (11). Este agregado ha de utilizarse como mecanismo para el intercambio de cabezales, como metodo de seguridad al desacoplar el cabezal como un todo finalizando el proceso de atencion del operador, asi como la practicidad para separar el cabezal c
