Description

인공치아 성형용 블록 및 그 제조방법{Block for plastic of artificial tooth and thereof manufacturing method}Block for artificial tooth molding and manufacturing method thereof

본 발명은 인공치아 성형용 블록을 제조하는 조성물과 인공치아 성형용 블록을 만드는 제조방법에 관한 것으로, 더욱 상세하게는 인체 친화적인 인공치아 성형용 블록을 제조하고 제조되는 블록의 강도나 경도를 조절할 수 있으며 그로 인해 자연치아의 손상과 마모를 줄일 수 있는 인공치아 성형용 블록 및 그 제조방법에 관한 것이다.The present invention relates to a composition for manufacturing an artificial tooth molding block and a manufacturing method for making an artificial tooth molding block, and more particularly, to manufacture a human-friendly artificial tooth molding block and to adjust the strength or hardness of the manufactured block. The present invention relates to an artificial tooth forming block and a method of manufacturing the same, thereby reducing damage and wear of natural teeth.

일반적으로 치과에서 진단을 받은 다음 인공치아를 시술하고자 할 경우 치과 의사가 치아의 본을 뜨게 되고 이 본을 기공소에 보내게 된다.In general, when a dentist attempts to perform an artificial tooth after being diagnosed at the dentist, the dentist opens a bone of the tooth and sends the bone to the laboratory.

이와 같이 기공소에서는 본 뜬 것을 토대로 하여 모델을 만든 다음 이 모델을 스캔하여 도면화하고 이 도면을 컴퓨터에 입력하여 인공치아를 가공장치인 소형 CNC선반을 이용하여 인공치아 성형용 블록을 고정한 다음 가공하며, 가공된 치아를 열처리하면 된다.In this way, the laboratory makes a model based on this pattern, scans the model, draws it into a computer, inputs the drawing into a computer, fixes the artificial teeth using a small CNC lathe as a processing device, and then processes it. , Heat treatment of the processed tooth.

가공장치는 소형 CNC선반과 같이 컴퓨터에 입력된 도면대로 드릴을 고정하고 있는 이송대가 상하좌우로 작동하여 인공치아 성형용 블록을 가공하게 되며, 이때 실제 치아보다 크게 가공되고 열처리 공정에서 축소된다.In the processing device, as the small CNC lathe, the feeder fixing the drill is operated up, down, left, and right to process the artificial tooth forming block, which is processed larger than the actual tooth and reduced in the heat treatment process.

상기와 같은 공정을 거쳐 완성된 인공 치아는 치과로 보내져 환자에게 고정하게 되는 것이다.Artificial teeth completed through the above process is sent to the dentist to be fixed to the patient.

그러나 상기 종래에서 사용되어온 인공치아 성형용 블록은 지르코니아 블록, 레진인레어 블록, 골든인레어 블록, PT크라운 블록 등이 사용되고 있다.However, zirconia blocks, resin in rare blocks, golden in rare blocks, PT crown blocks, and the like are used for the artificial tooth forming blocks conventionally used.

종래에 사용되어온 인공치아 성형용 블록은 강도가 너무 좋아 열처리한 후 보조가공이 어려울 뿐만 아니라 쉽게 파손되는 단점이 있다.Blocks for artificial tooth molding that have been used in the prior art has a disadvantage that the strength is so good that the secondary processing is not only difficult after the heat treatment.

즉, 치과에서 떠준 본을 토대로 하여 인공치아 성형용 블록을 가공공정과 열처리 공정에서 돌출된 부분이 발생하거나 손실된 치아와 결합할 때 부적합한 부분이 있을 경우 연마공정을 거쳐 연마하게 되는바, 이때 종래에 사용되어온 인공치아 성형용 블록으로 제작된 인공치아는 열처리 된 후 강도가 너무 강하여 파손되는 단점이 있어, 인공치아를 다시 제작하여야 하므로 원자재와 시간을 낭비하게 되는 문제점이 있다.That is, based on the bones drawn from the dentist, the artificial tooth forming block is polished through the polishing process when there is an unsuitable part when the protruding part is generated in the processing process and the heat treatment process or when it is combined with the lost tooth. Artificial teeth made of artificial tooth shaping blocks that have been used in the disadvantage that the strength is too strong after the heat treatment is broken, there is a problem that wastes raw materials and time because the artificial teeth must be produced again.

인이 함유된 인공치아용 블록을 만들기 위해서는 인이 함유된 안정한 물질을 찾아 그 물질을 사용하여 블록을 제조해야 하는데 이때, 인을 첨가할 수 있는 양이 정해져 있어, 원하는 인의 양을 조절할 수가 없었다.In order to make a block for artificial teeth containing phosphorus, it is necessary to find a stable substance containing phosphorus and manufacture the block using the substance. At this time, the amount to which phosphorus can be added is determined, and thus the amount of phosphorus desired cannot be controlled.

또한, 인의 양이 한정되므로 인공치아용 블록의 강도나 경도를 조절하기가 어려웠으며, 종래의 방법으로 인공치아를 만들 경우 자연치아의 손상과 마모를 가져올 수 있는 단점이 있었다.In addition, since the amount of phosphorus is limited, it is difficult to control the strength or hardness of the artificial tooth block, and when the artificial tooth is made by a conventional method, there is a disadvantage that it may cause damage and wear of natural teeth.

본 발명은 상기와 같은 문제점을 해소하기 위하여 안출 된 것으로서, 본 발명의 첫 번째 목적은, 인체 친화적인 인공치아 성형용 블록의 제조가 가능하고 초기 조성물이 안정적인 인공치아 성형용 블록 조성물을 제공하는 데 있다.
