Description

치과용 수복재 및 그 제조방법 Dental restorations and manufacturing method thereof
본 발명은 치과에서 사용하는 수복재의 제조방법 및 그 제조방법으로 제조된 치과용 수복재, 나아가 상기 치과용 수복재를 포함한 치아우식증 수복용 분말, 와동 임시충전용 분말 및 보철수복물 임시접착용 분말에 관한 것이다.The present invention relates to a method for producing a restorative material for use in dentistry, and to a dental restorative material prepared by the method, and further to a dental caries restoration powder including the dental restorative material, a vortex temporary filling powder and a prosthetic restoration temporary bonding powder. .
고령화와 소득 수준의 향상 및 건강에 대한 관심 증가로 자연치아 유지에 대한 열망은 나날이 높아지고 있다. 자연치아는 재생이 되지 않는다는 치명적인 한계를 가지고 있으며 세월이 흐름에 따라 충치, 치주질환 및 파절 등에 의한 경조직 손상이 불가피하게 일어나게 된다. 현재 손상된 치질을 수복하는 재료들은 아말감이나 복합레진같은 인공합성물이므로 생체친화적이지 못하다는 단점이 있으며 특히 치질(상아질)의 재생을 유도할 수 있는 능력이 전혀 없다. The aging of natural teeth is increasing day by day with aging populations, higher income levels and increased health concerns. Natural teeth have a fatal limitation that they cannot be regenerated and hard tissue damage due to tooth decay, periodontal disease and fracture will inevitably occur over time. Currently, the materials for repairing damaged hemorrhoids are artificial composites such as amalgam and composite resins, which are not biocompatible. In particular, they have no ability to induce regeneration of hemorrhoids.
보철 수복 치료를 반복하게 되면 치질의 삭제가 불가피하게 되며 불행하게도 천공 또는 수직 파절 등의 문제가 발생하게 된다. 현재 이런 경우에 사용되는 MTA (mineral trioxide aggregate)는 가격이 매우 비싸고 다루기가 매우 까다롭다는 단점 외에도 자연치아와 색상 차이가 많이 나며 혈액 등 체액에 용해되는 단점이 있어 크기가 큰 천공 등의 치료에는 사용이 제한적이다. 또한 직접적으로 상아질 또는 골조직을 형성할 수 있는 능력이 없다는 단점도 있다. Repeated prosthetic repair treatments inevitably remove hemorrhoids and unfortunately cause problems such as perforation or vertical fractures. MTA (mineral trioxide aggregate) used in this case is very expensive and very difficult to handle, and it has a color difference with natural teeth and dissolves in body fluids such as blood. Limited use It also has the disadvantage of not being able to directly form dentin or bone tissue.
한국공개특허 제 1999-0075022 호는 회화된 치아를 의료용 석고와 혼합하여 수복재로 사용하는 기술이 개시되어 있으나, 상기 회화과정을 통해 상기 상아질 또는 골조직의 유도능을 상실하게 되어 치아를 사용하는 장점이 사라지는 문제가 있다.Korean Laid-Open Patent Publication No. 1999-0075022 discloses a technique of mixing a painted tooth with a medical gypsum and using it as a restorative material. However, the painting process loses the ability to induce dentin or bone tissue through the painting process. There is a problem disappearing.

In addition, it has a great advantage as a temporary adhesive, and the removal of teeth for prosthetic restoration is very sensitive to temperature stimulation and in many cases causes pain. To prevent this, the tooth is protected by a temporary restoration. Temporary bonding is an essential process for proper fixation. The use of demineralized tooth components in the temporary adhesive used at this time helps to reduce tooth hypersensitivity and maintain the health of the pulp.

In describing the present invention, when it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.
본 발명은 자가치아, 가족치아, 동종치아, 이종치아와 같은 발치된 치아를 이용하여 치과용 수복재를 제조하는 방법에 관한 것이다. 치아는 법랑질, 상아질과 백악질로 구성되어 있으며 무기질은 인산칼슘계로 구성되어 있고 콜라겐과 비콜라겐성 단백질, 탄수화물, 지질 등 유기질을 포함하고 있다. The present invention relates to a method for producing a dental restorative using an extracted tooth such as autotooth, family tooth, allogeneic tooth, or heterogeneous tooth. Teeth are composed of enamel, dentin and chalkiness. Minerals are composed of calcium phosphate and contain organic materials such as collagen and non-collagen proteins, carbohydrates and lipids.
결손 부위를 자연치아를 이용한 수복재로 수복할 수 있다면 더 이상 좋은 수복재는 생각하기 어렵다. 좋은 수복재는 치아와 물리화학적 성질이 같아야 하는데 자연치아를 이용한 재료라면 이런 요건을 충분히 만족시킬 수 있다. 아울러 상아질 형성 능력이 있다면 초기 우식의 경우 최소 삭제만으로 수복할 수 있어 불필요한 자연치질의 삭제를 막을 수 있다. 또한 유아 또는 청소년의 경우 충치로 이환될 위험이 큰데, 치면열구전색제 (Pit and fissure sealant)로의 응용도 충분히 가능하다.If the defect can be repaired with a natural tooth restoration, a good restoration is no longer conceivable. A good restorative should have the same physicochemical properties as a tooth, and natural teeth can satisfy this requirement. In addition, if there is dentin formation ability, early caries can be repaired with only minimal deletion, thereby preventing unnecessary deletion of natural hemorrhoids. Infants or adolescents are also at high risk of caries, and application to a pit and fissure sealant is also possible.
그리고, 상아질 및 골 형성을 유도하는 수복재가 있다면 천공의 치료 뿐만 아니라 주변에 소실된 골조직의 재생도 기대할 수 있어, 치아 경조직 보존에 큰 도움이 된다. 같은 원리로 치근이 완성되지 않아 넓은 근단공을 가지는 치아의 근관 치료에도 사용될 수 있으며 자연 치아를 살리는 술식인 치근단 수술, 치아 재식술, 치아 이식술에서도 근단 폐쇄 및 상실된 상아질 조직의 재생 및 흡수된 주변 골조직 형성을 용이하게 하여 성공률을 높여 자연 치아의 유지에 큰 도움이 될 수 있을 것이다.In addition, if there is a restorative material that induces dentin and bone formation, the treatment of perforations as well as the regeneration of bone tissue lost in the surroundings can be expected, which is a great help in preserving dental hard tissue. The same principle can be used for root canal treatment of teeth with a wide root canal due to incomplete rooting. Facilitate the formation and increase the success rate can be a great help in the maintenance of natural teeth.
본 발명의 치과용 수복재의 제조방법은 이러한 목적을 달성하기 위하여, 먼저 치아 표면의 이물 및 치수강과 치근관 내의 연조직을 제거하는 단계로부터 시작된다. 여기서 치아는 발치 후 즉시 수복재 제조에 사용되지 않는다면 일단 냉장보관하는 것이 바람직하다. 그리고, 상기 이물이란 치아에 부착된 보철물, 수복물, 치석, 충치, 접착제 등을 가리키고, 연조직이란 치수 등의 조직을 가리킨다.In order to achieve this object, the method for producing the dental restorative material of the present invention starts with the step of first removing the foreign body of the tooth surface and the soft tissue in the pulp cavity and the root canal. It is preferred that the teeth be refrigerated once they are not used for the preparation of the restoration immediately after extraction. The foreign material refers to a prosthesis, a restoration, a dental plaque, a tooth decay, an adhesive, or the like attached to a tooth, and the soft tissue refers to a tissue such as a dimension.
상기 이물 및 연조직이 제거된 치아는 증류수나 식염수, 또는 알콜 등으로 세척하고 나서 평균입경 10 내지 200 ㎛로 분쇄하여 치아분말을 제조한다. 여기서, 분쇄는 미세골분쇄기 또는 호모지나이져(homogenizer) 등을 이용할 수 있으며, 이때 원료물질이 변질되지 않도록 분쇄과정에서 온도가 상승되지 않도록 주의한다.The foreign material and the soft tissue is removed, the tooth is washed with distilled water, saline, alcohol, etc. and then ground to an average particle diameter of 10 to 200 ㎛ to prepare a tooth powder. Here, the grinding may use a fine bone grinder or a homogenizer (homogenizer), etc. At this time, be careful not to increase the temperature during the grinding process so as not to deteriorate the raw material.
그런데, 치아 중 치관 부분은 주로 무기질 성분으로 구성된 법랑질(에니멜)이 많은 부분을 차지하기 때문에 골전도에 의한 치유 성향을 보이고 흡수가 다소 늦은 특성을 갖는다. 반면 치근 부분은 상아질(덴틴)과 백악질로 구성되어 있어 유기질 성분이 많이 포함되어 있고 골유도 및 골전도 기능을 발휘하고 치관 부분에 비해 흡수가 다소 빠른 양상을 보인다.By the way, the crown portion of the tooth is enamel (enamel) mainly composed of the inorganic components occupy a large part because it shows a tendency to heal by bone conduction and has a rather late absorption. On the other hand, the root portion is composed of dentin (dentin) and chalky, so it contains a lot of organic components, exhibits bone induction and bone conduction functions, and absorbs somewhat faster than the crown portion.
따라서, 치관과 치근을 나아가, 법랑질, 상아질, 백악질 별로 분리해서 수복재를 제조하면, 수복이 필요한 부위 예컨대 치아우식증이 발생한 부위에 따라 선택하여 적용할 수 있는 장점이 있다.Therefore, if the manufacture of the restoration by separating the crown and root, enamel, dentin, chalkaceous, there is an advantage that can be selected and applied according to the site that needs to be repaired, such as the site of dental caries.
그러므로, 상기 분쇄 전에 치아를 치관과 치근으로 분리하는 것이 바람직하고, 나아가, 상기 치관은 상아질과 법랑질로, 그리고 상기 치근은 상아질과 백악질로 분리되는 것이 더욱 바람직하다.Therefore, it is preferable to separate the tooth into the crown and root before the grinding, and furthermore, the crown is more preferably separated into dentin and enamel, and the root is separated into dentin and chalky.
이어서, 상기 분쇄된 치아분말을 세척하는데, 바람직하게는 증류수나 식염수, 또는 알콜로 세척 후 5 내지 7 중량%의 과산화수소수를 함유한 초음파 세척기로 수행할 수 있다.Subsequently, the pulverized tooth powder is washed. Preferably, the crushed tooth powder may be washed with distilled water, saline, or alcohol, followed by an ultrasonic cleaner containing 5 to 7 wt% hydrogen peroxide.
상기 세척된 치아분말은 탈지(defat) 후 세척하는 단계를 거치게 되는데, 탈지는 본 기술분야에서 사용되는 탈지제라면 제한 없이 사용될 수 있으며, 예컨대 에탄올, 에테르 또는 클로로포름-메탄올 혼합액을 사용할 수 있다.The washed tooth powder is subjected to a step of washing after defatting, and degreasing may be used without limitation as long as it is a degreasing agent used in the art, for example, ethanol, ether or chloroform-methanol mixture may be used.
상기 탈지된 치아분말은 탈수에 앞서 탈회(demineralize)하는 단계를 추가로 포함할 수 있다. 상기 탈회는 0.5N HCl 등에 30 분 내지 150분 동안 수회 침지시키는데, 탈회 횟수는 입자의 크기, 용도에 따라 달라지며, 입자가 작을수록 탈회 횟수를 적게 할 수 있다.The degreased tooth powder may further comprise a step of demineralizing prior to dehydration. The deliming is immersed several times for 30 minutes to 150 minutes in 0.5N HCl and the like, the number of deliming depends on the size and use of the particles, the smaller the particles can be reduced the number of deliming.
그리고, 상기 세척된 치아분말을 에탄올 등으로 탈수하고, -40 내지 -90 ℃의 온도에서 24 내지 60 시간 동안 냉동건조 후, 에틸렌 옥사이드 (ethylene oxide) 가스 또는 방사선 소독을 실시하고 멸균상태에서 포장하여 본 발명의 치과용 수복재를 제조한다.Then, the washed tooth powder is dehydrated with ethanol and the like, and freeze-dried at a temperature of -40 to -90 ℃ for 24 to 60 hours, ethylene oxide gas or radiation sterilization and packaging under sterilization The dental restoration of the present invention is prepared.
이렇게 제조된 치과용 수복재는 치아수복재 (pestorative filling material), 예방치료제 (preventive dental material), 치아열구전색제 (pit and fissure sealant), 임시수복재 (temporary filling material), 포스트코아재료 (post and core material)로서 활용이 가능하다.The dental restoratives thus prepared include: dental restorative materials, preventive dental materials, pit and fissure sealants, temporary filling materials, post core materials It can be used as.
