Description

임플란트의 지르코니아 어버트먼트 제조방법{A Zirconia Abutment Product Method For Implant} Zirconia Abutment Product Method For Implant

본 발명은 인공치아인 임플란트의 상부구조물 어버트먼트(Abutement)를 분말 사출 성형에 의해 용이하게 제조할 수 있도록 하는 임플란트의 지르코니아 어버트먼트 제조방법에 관한 것이다.The present invention relates to a method for producing an zirconia abutment of an implant to facilitate the manufacture of abutment of the superstructure of the implant which is an artificial tooth by powder injection molding.

일반적으로 임플란트는 인체 조직을 회복시켜주기 위한 대체물로서 예를 들어 인공관절 또는 인공치아와 같은 인공성형물을 의미한다.In general, an implant is a substitute for restoring human tissue, and means an artificial molding such as, for example, an artificial joint or an artificial tooth.

즉, 상실된 치아를 대신해 인공치아인 티타늄 임플란트로 만들어진 인공치근을 치조골 속에 매식하고 주위골과 유착될 때까지 일정한 치유기간을 거친 후 이 인공 치근 구조물의 상부에 금속이나 세라믹으로 된 어버트먼트(Abutement)를 연결하고 이 어버트먼트 위에 인공치관을 제작, 장착하여 상실된 자연치를 수복해주는 술식이다.In other words, instead of the missing tooth, the artificial tooth made of titanium implant, artificial tooth, is embedded in the alveolar bone and after a certain healing period until it is adhered to the surrounding bone, abutment made of metal or ceramic on top of the artificial root structure ) And the artificial crown is made on this abutment to repair the lost natural teeth.

특히 치의학 분야에서 인공치아 이식에 널리 사용되는 임플란트는 인접치아 를 손상시키지 않고 시술하므로 다른 치아를 보호할 수 있고 건강한 자연치아에 필적하는 저작력 회복을 가능케 하는 장점을 갖는다.In particular, implants, which are widely used for implantation of artificial teeth in the dentistry field, are operated without damaging adjacent teeth, so that they can protect other teeth and allow the restoration of chewing power comparable to healthy natural teeth.

또한, 섬세하게 시술된 임플란트는 잇몸 속에 이가 묻혀 있는 것과 같이 자연스러운 모양을 가지며, 이가 전혀 없는 틀니환자나 부분적인 틀니환자인 경우에도 몇 개의 임플란트를 통해 틀니의 안정을 도모할 수 있고 틀니와 잇몸과의 마찰로 생기는 상처로 인한 통증도 없앨 수 있으며 틀니의 장기간 사용으로 살생하는 잇몸의 소실도 방지하는 효과가 있다.In addition, the delicately implanted implant has a natural shape as if it is buried in the gums, and even in the case of dentured or partial dentured patients without teeth at all, several dentures can stabilize the dentures, The pain caused by the friction of the teeth can be eliminated, and the prolonged use of dentures also prevents the loss of killing gums.

이러한 임플란트는 상실된 치아의 치근을 대신할 수 있도록 인체 거부반응이 없고 내식성이 좋은 티타늄(Titanium)으로 만들어지며, 종래에는 대부분 선반과 같은 절삭용 기계를 이용하여 가공하고 있다.Such implants are made of titanium (Titanium) having no human rejection and corrosion resistance so as to replace the root of the missing tooth, and is conventionally processed using a cutting machine such as a lathe.

그런데 이와 같이 임플란트를 만들기 위하여 소정의 재료를 선반을 통하여 절삭가공함에 따라 사용재료의 소모가 많아질 뿐만 아니라 오랜 가공시간이 소요되는 문제점이 있었다.However, in order to cut the predetermined material through the lathe in order to make the implant as described above, there is a problem that the consumption of the used material increases as well as a long processing time.

또한, 지르코니아 어버트먼트는 기존 티타늄 어버트먼트와 달리 세라믹으로 제조되어 치아색상을 발현함으로써 심미적으로 우수하고 생체 친화성이 우수하여 높은 강도와 인성을 가지고 있다.In addition, unlike conventional titanium abutments, zirconia abutments are made of ceramic to express tooth color and thus have excellent aesthetics and biocompatibility, and thus have high strength and toughness.

지르코니아는 기능적으로 좋은 장점을 가지고 있지만 재료 경도가 높아 일반 치공구로는 가공이 불가능하고 다이아몬드 치공구를 제작하여 성형하여야 하는 어려움과 가공기간이 길어져 댜량생산체계를 갖추기 위해서는 비싼 가공기를 여러대 보유하여야 하므로 자본투여가 많아져 원가상승의 주원인이 되고 있다.Zirconia has the advantage of being functional, but the high hardness of the material makes it impossible to process with ordinary tools, and the difficulty of forming and molding diamond tools is long and the processing time is long. More administration has become the main cause of cost increase.

상기 문제점을 개선하기 위한 본 발명은 가공상의 어려움이나 단가적인 문제를 보완하고 대량생산 및 제품 품질의 안정성을 도모할 수 있도록 성형사출에 의해 보다 용이하게 제작하도록 하는 것으로 사출방식 재료의 종류에 따라 MIM(Metal Injection Molding)과 CIM(Ceramic Injection Molding)으로 성형하는 임플란트의 지르코니아 어버트먼트 제조방법을 제공하는데 그 목적이 있다.The present invention for improving the above problems to make it easier to manufacture by molding injection to compensate for the difficulty of processing or the unit cost problem and to promote the stability of mass production and product quality MIM according to the type of injection type material It is an object of the present invention to provide a method for manufacturing zirconia abutments of implants molded by (Metal Injection Molding) and CIM (Ceramic Injection Molding).

이하 첨부된 도면에 의거하여 본 발명의 실시예를 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명 실시예에 따른 지르코니아 어버트먼트의 제조 공정도이다.1 is a manufacturing process chart of the zirconia abutment according to an embodiment of the present invention.

본 발명의 실시예에 따른 지르코니아 어버트먼트의 제조 공정은 원재료혼합공정, 성형사출공정, 용매추출공정, 탈지공정, 소결공정 및 바렐공정으로 이루어 진다.The manufacturing process of the zirconia abutment according to the embodiment of the present invention consists of a raw material mixing process, molding injection process, solvent extraction process, degreasing process, sintering process and barrel process.

상기 원재료혼합공정은 용매성분 재료로서 EVA, 파라핀왁스(Wax), LDPE과 스테아린산으로 이루어져 사출공정시 점도를 갖도록 하는 중합체 15~19중량%와; 지르코니아(ZrO2) 80~85중량% 및 색상발현을 위한 산화철(Fe2O3) 1~4중량%를 혼합 분쇄하여 120℃ ~ 150℃의 온도로 3 ~ 4시간 가열 혼합하여 성형사출을 위한 원재료를 가공한다.The raw material mixing process is 15 to 19% by weight of a polymer composed of EVA, paraffin wax (Wax), LDPE and stearic acid as a solvent component to have a viscosity during the injection process; Zirconia (ZrO 2 ) 80 ~ 85% by weight and 1 to 4% by weight of iron oxide (Fe 2 O 3 ) for color expression mixed and pulverized for 3 to 4 hours by heating and mixing at a temperature of 120 ℃ ~ 150 ℃ for molding injection Process raw materials.

상기 원재료혼합공정의 용매성분 재료로 투입되는 중합체는 EVA 7~30중량%, 파라핀Wax 50~65중량%, LDPE 15 ~35중량%, 스테아린산 1~5중량%로 조성된다.The polymer introduced as the solvent component material of the raw material mixing process is composed of 7 to 30% by weight of EVA, 50 to 65% by weight of paraffin wax, 15 to 35% by weight of LDPE, and 1 to 5% by weight of stearic acid.

상기 성형사출공정은 상기 원재료혼합공정에 의해 혼합된 원재료를 사출기에 투입하여 성형한다.In the molding injection process, raw materials mixed by the raw material mixing process are put into an injection molding machine.

사출 성형시 사출온도는 130 ~ 160℃가 바람직하며, 이와 같은 성형사출공정에서 사출된 사출물은 취성이 강하여 작업시 매우 주의를 요한다.When injection molding, the injection temperature is preferably 130 to 160 ° C, and the injection molded product in such a molding injection process is very brittle and requires great care during operation.

따라서, 원활한 가공 및 제품의 품질을 향상시키기 위해서는 상기 성형사출된 사출물에 대하여 취성을 약화시키고 연성이 생기도록 하는 공정이 요구된다.Therefore, in order to smoothly process and improve the quality of the product, a process for weakening brittleness and ductility of the molded injection molded product is required.

탈지공정은 상기 용매추출공정에 의해 용매 중 일부가 추출된 사출물로 부터 용매성분을 모두 제거하도록 공정으로서 상기 용매추출공정에 의해 일부의 용매가 추출된 사출물로 부터 용매성분을 완전히 제거하도록 850 ~ 950℃에서 23 ~ 25시간 동안 용매를 제거하도록 한다.The degreasing step is to remove all of the solvent components from the injection product from which some of the solvent is extracted by the solvent extraction step. The degreasing step is performed to completely remove the solvent components from the injection product from which some solvent is extracted by the solvent extraction step. Remove the solvent at 23 ° C. for 23-25 hours.

소결공정은 상기 탈지공정 후 용매가 제거된 탈지체를 소결하여 기계적 물성을 갖도록 하는 공정으로서 상기 탈지공정 후 용매가 제거된 탈지체를 1200 ~ 1800℃에서 20 ~ 48시간 동안 소결한다.The sintering step is a step of sintering the degreased body from which the solvent is removed after the degreasing process to have mechanical properties. The desintered body from which the solvent is removed after the degreasing process is sintered at 1200 to 1800 ° C. for 20 to 48 hours.

상기 바렐공정은 상기 소결공정에 의해 소결된 소결체를 외면을 연마하여 광 택성과 미세 버(Burr)를 제거하도록 하는 것이다.The barrel process is to polish the outer surface of the sintered body sintered by the sintering process to remove glossiness and fine burrs.

상기 탈지공정과 소결공정은 하나의 탈지소결로에서 연속적으로 이루어져 작업성을 좋게 하였다.The degreasing process and the sintering process are made in one degreasing furnace to improve the workability.

이와 같은 본 발명은 사용분말의 종류에 따라 MIM(Metal Ijection Molding), 또는 CIM(Ceramic Injection Molding)으로 분류한다.The present invention is classified into MIM (Metal Ijection Molding) or CIM (Ceramic Injection Molding) according to the type of powder used.
