Description

치아 보철물 연마용 연마제의 제조방법{Manufacturing method of abrasie for dental prosthesis}Manufacturing method of abrasive for abrasive tooth prosthesis {Manufacturing method of abrasie for dental prosthesis}

본 발명은 충치 치료후 치아나 주위조직의 결손 회복을 위한 보철물의 제작시 보철물을 연마하는 데 이용되는 연마제의 제조방법에 관한 것이다.The present invention relates to a method for producing an abrasive used to polish a prosthesis in the production of a prosthesis for repairing a defect in a tooth or surrounding tissue after caries treatment.

치아보철용 보철물은 대표적으로 비귀금속제인 티타늄과 귀금속제인 금을 예로 들 수가 있으며, 치아형태로 주형성형하여 그 표면을 상마와 연마한 후 손상된 치아를 덮어 씌워 주도록 하고 있다.For example, the prosthetic prosthesis may include titanium, which is a non-noble metal, and gold, which is a noble metal. The prosthesis is formed in the form of a tooth to cover the damaged tooth after polishing the surface with an upper hemisphere.

이러한 보철물들은 주로 치 기공소에서 제작되는 것으로서, 완제품을 얻기까지의 종래의 작업공정을 살펴보면, 주형성형 후 마이크로 모터가 내장된 핸드피스 단부에 스톤 포인트(Stone Point)를 결합하여 주조물의 거친 표면을 1차 연마하고, 1차 연마후 러버휠(Rubber wheel)을 교체하여 2차연마하고, 2차 연마 후 러버포인트(Rubber Point)를 교체하여 3차 연마하고, 3차 연마 후 연마제를 묻힌 연마휠과의 마찰에 의한 4차연마로 광택이 나는 완제품을 얻도록 하고 있다.These prostheses are mainly manufactured in dental laboratories. Looking at the conventional process of obtaining a finished product, the rough surface of the casting is formed by combining a stone point at the end of a handpiece with a micromotor embedded after molding. After the first polishing, after the first polishing, the rubber wheel is replaced by second polishing. After the second polishing, the rubber point is replaced by the third polishing. After the third polishing, the polishing wheel with the abrasive is applied. It is intended to obtain a polished finished product by the fourth polishing by friction.

따라서 3차에 걸친 상마작업이 매우 까다로워 연마작업시 숙련된 전문인력을 필요로 하므로 인건비가 많이 소요되고 또 4차에 걸친 복잡한 연마 작업공정과 상마공정 중 3차례에 걸친 연마재료의 교체시간이 추가되므로 생산성이 현저히 저하되며, 이는 결국 영세한 치 기공소들의 채산성을 약화시킬뿐 아니라 환자들의 치료비 부담을 그 만큼 더 가중시키게 된다.Therefore, three rounds of grinding work are very demanding, which requires skilled manpower for polishing work, which requires a lot of labor costs, and adds four times of complicated grinding work and three replacements of grinding materials. As a result, productivity is markedly lowered, which in turn weakens the profitability of small dental laboratories and adds to the treatment burden on patients.

또한 상마작업시 이용되는 스톤포인트와 러버휠 그리고 러버포인트 등은 전량 수입에 의존하는 고가의 소모품이고, 연마제 또한 국내 일부업체에서 생산되고 있기는 하나 질이 떨어져 거의 대부분 고가의 수입 연마제를 사용하고 있는 현실정을 감안할 때 추가비용 부담이 커 제조경비는 더욱 상승하게 되고, 또 국가적으로도 큰 손실을 가져오게 되므로 이에 대한 대책이 시급한 실정이다.In addition, stone point, rubber wheel, and rubber point used in the work of horseshoe are expensive consumables that depend on the whole imports, and abrasives are produced by some domestic companies, but they are mostly of high quality imported abrasives. Considering the facts, the additional cost burden will increase manufacturing costs, and the country will also have a big loss. Therefore, countermeasures are urgently needed.

이에 본 발명은 연마휠을 이용한 연마작업시 상마작업이 동시에 이루어질 수가 있는 연마제의 제조방법을 제공함에 그 목적이 있다.Accordingly, an object of the present invention is to provide a method for preparing an abrasive, which can be made at the same time the polishing operation during the polishing operation using the polishing wheel.

상기한 목적달성을 위하여 본 발명은 분말화된 규조토와 광분과 산화크롬과 입자가 작고 고운 산화알루미나와 입자가 크고 거친 산화알루미나와 분말화된 글라스비드(Glass Bead)를 혼합하여, 여기에 스테아린산 고체(Stearic Acid)와 파라핀왁스(Paraffin Wax)를 녹여서 투입하여 반죽하고, 반죽 후 덩어리로 뭉쳐서 완제품을 얻도록 함을 특징으로 한다.In order to achieve the above object, the present invention mixes powdered diatomaceous earth, light powder, chromium oxide, small particle and fine alumina oxide, particle large and coarse alumina oxide and powdered glass beads, to which stearic acid solid (Stearic Acid) and paraffin wax (Paraffin Wax) is melted and kneaded, and kneaded after kneading, characterized in that to obtain a finished product.

분말화된 규조토 2∼8g 과, 광분 약 6∼12g 과, 산화크롬 약 11∼19g 과, 입자크기가 5~15㎛ 의 산화알루미나(Aluminium Oxide) 약 7∼15g 과, 입자크기가 50∼10㎛의 산화알루미나(Aluminium Oxide) 15∼23g 과 글라스비드(Glass Bead)15∼23g 을 무순으로 혼합하고, 여기에 스테아린산 고체(Stearic Acid) 7∼15g 과 파라핀왁스(Paraffin Wax) 7∼15g을 녹여서 투입하여 충분히 반죽한 다음 소정의 크기로 덩어리화 하여 완제품을 얻도록 하는 방법으로 제조하여서 된 것이다.2 to 8 g of powdered diatomaceous earth, about 6 to 12 g of light powder, about 11 to 19 g of chromium oxide, about 7 to 15 g of aluminum oxide having a particle size of 5 to 15 μm, and particle size of 50 to 10 15-23 g of aluminum oxide (μm) and 15-23 g of glass beads (Glass Bead) are mixed randomly, and 7-15 g of stearic acid and 7-15 g of Paraffin Wax are dissolved therein. It was prepared by the method of kneading by adding enough dough and then clumping to a predetermined size to obtain a finished product.

이와 같은 방법으로 제조되는 본 발명의 연마제는 적당량을 연마휠에 묻히고 연마하고자 하는 보철물을 고속회전하는 연마휠에 접촉시켜 주게 되면 상마와 연마작업이 동시에 이루어지게 된다.When the abrasive of the present invention prepared in this manner is buried in the appropriate amount on the polishing wheel and the prosthesis to be polished is brought into contact with the polishing wheel rotating at high speed, the upper and lower polishing operations are performed at the same time.

또한 연마시 치아보철물의 교합면에 구(溝;groove)와 와(窩;fossa)의 깊은 곳도 연마용 기구인 로빈슨 브러쉬(Robinson brush)에 본발명 연마제를 묻혀서 고속회전과 저속회전을 가하게되면 빠른 시간에 보철물을 고광택으로 연마해 줄 수가 있게된다.In addition, when the abrasive of the present invention is buried in the deep surface of the groove and fossa on the occlusal surface of the dental prosthesis, the abrasive brush of the present invention is applied to the high speed and low speed rotation. Prosthesis can be polished with high gloss in a short time.

따라서 일명 콤파스이론에서 구(溝;groove)에는 연마를 할 수 없다고 주장하고 있으나, 본발명 연마제를 이용할 경우 100% 연마가 되는 것을 현미경으로 확인하였다.Therefore, the so-called compass theory insisted that it was not possible to grind a sphere, but it was confirmed by a microscope that 100% polishing was carried out using the present invention abrasive.

이때 연마제를 구성하는 재료들 중 입자크기가 약 50∼100㎛으로서 입자가 크고 또 표면이 거친 산화알루미나는 주형성형 후 보철물의 거친 표면을 깍아내는 상마공정을 대신하게 된다.At this time, among the materials constituting the abrasive, the particle size is about 50 to 100 μm, and the alumina oxide having a large and rough surface replaces the blasting process of shaving the rough surface of the prosthesis after the casting mold.

또한 규조토와 광분, 산화크롬, 그리고 입자크기가 약 5~15㎛의 산화알루미나는 기존에도 광택제로서 흔히 이용되는 것으로서, 입자가 곱고 또 미세하므로 상마 후 광택을 내는 연마공정을 충실히 수행하게 된다.In addition, diatomaceous earth, light powder, chromium oxide, and alumina oxide having a particle size of about 5 to 15 μm are conventionally used as a polishing agent, and since the particles are fine and fine, the polishing process for polishing after the polishing is faithfully performed.

또한 글라스비드는 귀금속이나 비귀금속들의 산화막을 제거하여 고유의 색상이 드러나게 하는데 탁월한 기능을 발휘하게 된다.In addition, the glass bead has an excellent function of revealing the unique color by removing the oxide film of the precious metal or non-noble metal.

이때 상마역활을 하는 입자가 크고 거친 산화알루미나는 연마작업이 동시에 이루어짐에 따라 연마작업에도 영향을 미쳐서 보철물의 표면을 거칠게 하는 것이 아닌가 하는 의구심을 가질수도 있다하겠으나, 전체 차지하는 비율은 약 15∼25%로서, 수차례의 시험결과 연마휠의 고속회전으로 단시간에 상마역할을 수행하면서 갈수록 보철물과 접촉한 부분은 마모되어 표면이 매끈해지고 또 나머지 약 75∼85%를 차지하는 입자가 고운 규조토와 광분 산화크롬 등과의 상호작용 및 보호작용으로 오히려 보철물의 표면을 더욱 매끈하게 연마해 주는 것을 현미경을 통한 관찰로 확인하였다.At this time, as the abrasive grains are large and coarse alumina may be affected by polishing as the polishing is performed at the same time, the surface of the prosthesis may be rough, but the ratio of the total occupancy is about 15 to 25%. As a result of several tests, the portion of contact with the prosthesis gradually wears out while performing the normal role of the polishing wheel at high speed by the high speed rotation of the polishing wheel, and the surface becomes smooth, and the fine particles of the diatomaceous earth and light chromium oxide occupy about 75 to 85%. It was confirmed by microscopic observation that the surface of the prosthesis was smoothly polished by interaction and protection with the back.

따라서 본 발명은 상마와 연마 및 산화막을 제거하여 금속 고유의 색상이 드러나게 하는 물질들로 구성되므로 상마와 연마작업이 동시에 이루어질 수가 있고 더 나아가 보철물의 표면을 더욱 매끈하고 광택있게 연마해 줄 수가 있게 되는 것이다.Therefore, the present invention is composed of materials that reveal the unique color of the metal by removing the yam and polishing and oxide film, so that the yam and polishing work can be performed at the same time, and furthermore, the surface of the prosthesis can be polished more smoothly and lustrously. will be.

이와 같이 본 발명은 고속회전하는 연마휠에 연마제를 묻히고 연마하고자 하는 보철물을 연마휠에 마찰시켜 주게 되면 상마와 연마 작업이 동시에 이루어지게 되고 또 연마작업시 글라스피드는 산화피막을 없애주게 되므로 보철물의 표면을 더욱 광택있게 연마해 줄 수가 있어 상품으로서의 가치를 높여줄 수가 있게 된다.Thus, in the present invention, when the abrasive is buried in the polishing wheel rotating at high speed, and the prosthesis to be polished is rubbed on the polishing wheel, the upper end and the polishing work are performed at the same time, and the glass feed removes the oxide film during polishing. The surface can be polished more glossly, thereby increasing the value as a product.

또한 숙련된 전문인력에 의해 이루어지는 여러 단계의 상마공정을 없애줄 수가 있고 또 연마휠을 통한 연마작업은 단순작업으로서 전문성을 요하지 않아 인건비를 줄일 수가 있다.In addition, it is possible to eliminate the multi-stage lattice process performed by skilled professionals, and the polishing work through the polishing wheel is a simple work, which does not require expertise and can reduce labor costs.

또한 복잡한 상마공정을 없애주는 만큼 작업능률은 훨씬 배가되어 생산성 향상을 가져오게 되므로 치기공소의 채산성을 높여주면서 환자들에게 보다 싼값으로 보철물을 제공해 줄 수가 있으며, 전량 수입에 의존하던 소모성 연마재료(스톤포인트, 러버휠, 러버포인트 등)를 필요치 않아 더욱 저렴한 비용으로 보철물을 제작할 수 있을 뿐아니라 수입대체 효과로 국가적으로도 큰 이익을 가져다 줄 수가 있는 유용한 발명인 것이다.In addition, as the work efficiency is greatly doubled, which eliminates the complicated process, the productivity can be improved, and the prosthesis can be provided to the patients at a lower cost while improving the profitability of the dental laboratories. Points, rubber wheels, rubber points, etc.) is a useful invention that can produce a prosthesis at a lower cost as well as bring great benefits to the country as a substitute for imports.
