Abstract: The present invention discloses an induction heating type dental filling device including a body unit grippable by a user, a filling unit containing a refillable filling material and connected to the body unit so that one side thereof is insulated from the body unit, a heating unit disposed in close contact with the filling unit and heating the filling material using induced current to convert the filling material into a liquid state, a pressing unit for pressing the heated filling material to discharge the heated filling material to the outside of the filling unit, and a shielding unit for shielding the heat and magnetic field of the heating unit. According to this configuration, heat loss through the filling unit may be prevented and clamping force for the body unit may be excellent, so that the efficiency of filling a filling material for dental treatment may be improved.

Abstract: Disclosed is a microneedle including at least one tip portion that is capable of penetrating the skin and includes a liquid medicine melted in the skin; a base portion supporting the at least one tip portion; and at least one guide portion that is provided between the at least one tip portion and the base portion, is made of a non-soluble material, and is protruded in a direction in which the at least one tip portion penetrates the skin to couple with the at least one tip portion. In accordance with such a configuration, the at least one tip portion may be instantly separated in a short time, whereby superior liquid medicine supplyability is exhibited.

Abstract: A method of manufacturing a microneedle according to the present disclosure includes a step of preparing a microneedle; a step of cooling the microneedle; and a step of inducing an endothermic reaction of the cooled microneedle, and coating the cooled microneedle with an active ingredient at least once. In accordance with such a configuration, coatability of the active ingredient can be improved due to an endothermic reaction without a separate drying process, thereby providing superior medication.

Abstract: A dental treatment instrument includes a bridge unit, and a first tip and a second tip unit each configured to be replaceable with respect to the bridge unit, where the bridge unit includes a first lengthwise groove formed in a lengthwise direction at one end of the bridge unit, a first circumferential groove extending from the first lengthwise groove in a first circumferential direction, a second lengthwise groove formed in the lengthwise direction at the other end of the bridge unit, and a second circumferential groove extending from the second lengthwise groove in a second circumferential direction different from the first circumferential direction, and the first tip unit includes a first coupling protrusion extending in a direction vertical to the lengthwise direction of the bridge unit, and the second tip unit includes a second coupling protrusion extending in a direction vertical to the lengthwise direction of the bridge unit.

Abstract: A vibrator for attaching composite resin to a tooth includes a housing, a vibration motor accommodated in the housing and configured to generate vibration, a micro-computer configured to control an operation and a vibration frequency of the vibration motor, a vibration tip configured to couple with one side of the housing to be exposed to an outside of the housing and to transfer the vibration to the composite resin, a vibration bushing provided at one end of the vibration tip and accommodated in the housing, and a control switch provided on one side of the housing and configured to generate a vibration motor control signal in response to a user contacting or pushing the control switch.

Abstract: Disclosed is a dental treatment instrument including a bridge unit configured to be gripped by a user; a plurality of tip units configured to be replaceable with respect to the bridge unit; and a coupling unit configured to selectively couple the tip unit with the bridge unit. The coupling unit is configured to couple the tip unit with the bridge unit by inserting and thereby rotating a portion of the tip unit relative to the bridge unit. Through this configuration, various types of dental tips may be easily replaced based on a selection of a user.
