Abstract: An anti-vibration mechanism for dental impression material mixer. The mechanism includes a plurality of supporting poles, a plurality of first elastic springs, a plurality of second elastic springs, a base plate and a restricting board. One end of both the first elastic spring and the second elastic spring are linked to the supporting pole, and the other end is linked to the top and the bottom of a motor respectively. The position of the motor is restricted at a central opening of the restricting board, and the motor is hanging above the base plate. Since the present invention is mainly dependent on the resilient elongation of the first elastic spring and the second elastic spring, which are linked on the top and the bottom of the motor respectively the present invention are absorb the vibration when the motor is operating and enhance the stability of the motor and every mechanism mounted on its top.

Abstract: A circulating cooling structure for optical curing apparatus which emits light of a selected wavelength to cure dental material such as a filler of teeth includes a casing and a heating element located in the casing which has an air inlet at one side where the heating element is located in a corresponding manner to receive air intake and an air outlet to allow the intake air to pass through the heating element and be discharged outside, thereby to provide an effective cooling means. When the optical curing apparatus is in use the air inlet is located at a lower side while the air outlet is located at a higher side, thus heated air flows upwards due to convection and external air can pass through the heating element to carry away a portion of heat energy and be discharged outside to achieve cooling effect.

Abstract: An optical curing apparatus includes a front shell body which consists of a first shell and a second shell that are coupled in a detachable and turnable manner. A light channeling member is fastened to the first shell and may be adjusted angularly to suit user's requirements. The light channeling member and the first shell are detachable. They are adaptable to the light channeling member of various diameters, and may be removed for sterilizing, or become a disposable and replaceable item. A radiation member and an electric power supply unit are provided and detachably coupled through a connector. The radiation member is reusable even if the case is damage or other elements are breakdown.

Abstract: An optical curing apparatus to rapidly cure a dental resin filling in a decayed tooth includes a case, a radiation member located at the front end of the case having a light generating element built thereon and a seat coupling with a light channeling element. The seat is coupled with the case to connect one end of the light channeling element to the light generating element. The connection juncture of the light generating element and the light channeling element is covered by a shield which provides a shielding effect to fully direct the light generated by the light generating element in the light channeling element so that the light may be gathered and channeled to the front end of the light channeling element to rapidly cure the dental resin filling in the decayed tooth. Thus light projection time may be reduced at a smaller power output to save electricity consumption and increase life span and reduce cost.
