- the term 'spherical' in the present invention includes all shapes similar to spheres, such as polyhedrons with relatively smooth edges or surfaces, including complete spheres.
- the binder is used to improve the strength of the injection molded body while providing fluidity so that the feedstock is uniformly injected into the mold during the injection process.
- a conventional single binder may be used, and in some cases, various kinds of binders having different melting points may be used together.
- the binder may be used by mixing paraffin wax, polyethylene, polypropylene, stearic acid, and the like.
- the binder may include a binder, a lubricant, a plasticizer, a surfactant, and the like.
- the present invention is not limited thereto, and the mixing ratio of the feedstock may be variously changed according to the required conditions.
- the injection molding is a dental stock as the feedstock is injected into the mold having a cavity (cavity) of a predetermined shape so that the shank portion 110 and the working portion 120 may be integrally formed and cooled / solidified in the mold.
- the injection molded body of the implant scale tip 100 is taken out.
- the volume of the injection molded body is reduced while the solvent and the air bubbles are discharged during the injection and degreasing and hot degreasing step (S13, S14) and the sintering step (S15), so that the injection step (S12) Taking into account the volume reduction of the injection molding, an injection molding having an increased volume compared to the scaler tip 100 for the dental implant to be finally formed is formed.
- a degreasing step for removing the binder contained in the injection molded body is performed (S13, S14).
- the solvent degreasing step (SS13) is a wax such as paraffin wax in the binder included in the injection molding using a solvent such as N-hexane (N-Hexane), heptane (Thinner), thinner (Thinner), etc.
- the hot degreasing step (S14) removes the remaining binder by applying heat to the injection-molded injection body.
- the present invention is not limited thereto, and other degreasing processes such as electrolytic degreasing and ultrasonic degreasing may be applied in addition to the solvent degreasing S13 and the hot degreasing S14.
- the degreasing completed injection molded body is sintered in a predetermined temperature and hydrogen or an inert atmosphere to produce a scaler tip 100 for dental implants (S15).
- the sintering temperature, time and atmosphere are determined according to the type and particle size of the powder used in the feedstock and the type of additive.
- the scale tip 100 formed of 99% silver may be sintered at 800 to 960 ° C
- the scale tip 100 formed of 99% copper may be sintered at 950 to 1080 ° C.
- the hot degreasing step S14 may be simultaneously performed in the sintering step S15. That is, by inserting the injection molded body subjected to the solvent degreasing step (S13) into a sintering furnace for sintering and applying heat, the remaining binder is removed from the injection molded body by heat, and at the same time, the injection molded product is sintered. According to the present embodiment, by combining the hot degreasing step and the sintering step, the manufacturing process of the scaler tip can be shortened and productivity can be improved.
- the scale tip 100 is formed of a material having a lower hardness and strength than the object in order to prevent surface damage to the target tooth or implant.
- the implant is typically formed of titanium
- the scaler tip 100 is formed of silver, copper, silver alloy, or copper alloy to prevent surface damage to the implant fixture of titanium material or a prosthesis of ceramic or metal material. do.
- titanium used in implants is divided into Grade 1 (UNS R50250; ASTM Grade 1) to Grade 4 (UNS R50700; ASTM Grade 4), depending on the oxygen content in the titanium material.
- Grade 4 with hardness of 122 HV and high oxygen content Vickers hardness is about 280 HV.
- the scale tip 100 has a lower hardness than the titanium for the implant, and after the sintering is completed, the scale tip 100 has a hardness of 100 HV or less. According to the embodiments of the present invention, since the scale tip 100 has a lower hardness than ceramic or titanium as the object, the scale tip 100 itself may be worn during treatment to prevent surface damage, cracks, and fractures on the object.
- the scaler tip 100 has a hardness lower than that of titanium and a density and specific gravity similar to those of stainless steel. It is formed of copper and silver or a copper alloy or silver alloy.

- the weight of the scaler tip 100 may be somewhat heavy depending on the content of copper or silver, and at this time, a problem of lowering the ultrasonic frequency may occur, thereby reducing the size of the scaler tip 100 or modifying the shape according to the specific gravity of the material. It has a weight similar to that of a conventional stainless steel scaler tip.
- the scale tip 100 is formed of a powder having an average particle size of 0.1 to 30 ⁇ m and a spherical or spherical shape and smooth surface shape in order to improve the mixing and injection properties of the feedstock during powder injection molding and to secure sinterability. do. That is, when the particle size of the powder is smaller than 0.1 ⁇ m, the mixing and injection of the feedstock is difficult, and when the particle size of the powder is larger than 30 ⁇ m, the sinterability is inferior. And the shape of the powder is spherical or similar to the spherical shape and has a smooth and smooth surface shape is advantageous when mixing and injection of the feedstock.
- the scale tip 100 may sinter the scale tip 100 formed of copper and silver or a copper alloy or silver alloy (S15), and then perform a plating step on the sintered scale tip 100 (S16). . Since the scale tip 100 is sterilized at a temperature of 100 ° C. or higher at every use, the scale tip 100 formed of copper and silver or a copper alloy or a silver alloy is easily discolored due to oxidation. The surface of the scaler tip 100 is plated to prevent oxidation. The plating is also formed of a material having a lower hardness than the object, and uses gold or silver that is harmless to the human body and has good affinity. However, in the case of the scale tip 100 formed of silver, since the silver material has low oxidizing property, gold or silver plating treatment for preventing surface oxidation may be omitted.
