Description
본 발명은 플렉서블 3D 프린팅 레진으로 제조된 교정용 마우스 가드에 관한 것으로, 보다 구체적으로 온도 변화에 따라 물성이 변함으로써 구강 내에 편리하게 장착할 수 있는 교정용 마우스 가드에 관한 것이다.The present invention relates to an orthodontic mouth guard made of flexible 3D printing resin, and more specifically, to an orthodontic mouth guard that can be conveniently installed in the oral cavity by changing physical properties according to temperature changes.
일반적으로, 마우스가드(Mouth Guard)는 마우스피스(Mouthpiece)나 스플린트(Splint)라고도 하며, 치아에 피착되어서 외부 충격으로부터 치아, 더 나아가 턱관절을 보호하는 구강 내 구조물을 말한다. 보다 구체적으로, 상기 마우스가드는 치아에 장착되어서, 격투기나 구기 등의 운동 중에 주먹이나 공 등에 의해 안면에 충격이 가해질 때, 상기 치아와 악관절의 손상을 방지하며, 합성수지, 고무, 실리콘 또는 라텍스 등의 소재로 만들어진다.In general, a mouth guard, also called a mouthpiece or splint, refers to a structure in the oral cavity that is attached to the teeth and protects the teeth and, by extension, the temporomandibular joint from external shock. More specifically, the mouth guard is mounted on the teeth to prevent damage to the teeth and temporomandibular joint when the face is impacted by a fist or ball during sports such as fighting or ball games, and is made of synthetic resin, rubber, silicone, latex, etc. It is made from materials of
상기 마우스가드는 이갈이나 코골이 치료 혹은 치열 교정 치료에도 적용되며, 치아의 화이트닝에도 적용되는 등 환자 및 착용자의 사용 목적 및 구강 상태에 따라 다양한 용도로 그리고 다양한 형태로 적용된다. 참고로, 이갈이나 이악물기가 진행되면 치아마모, 잇몸퇴축, 턱관절질환 등 다양한 문제가 동반될 수 있는데, 이러한 환경에서 치아를 보호하는데 상기 마우스가드가 사용될 수 있다.The mouthguard is applied to bruxism, snoring, orthodontic treatment, and is also applied to teeth whitening, and is used for various purposes and in various forms depending on the purpose of use and oral condition of the patient and wearer. For reference, as teeth grinding or clenching progresses, various problems such as tooth wear, gum recession, and temporomandibular joint disease may occur. The mouth guard can be used to protect teeth in such environments.
이러한 마우스가드는, 치과에서 적절한 검진을 통해 구강 내의 상태에 대한 정확한 자료의 채득이 이루어진 다음, 가공 과정에서 턱관절의 위치 및 교합상태 등을 확인하여 제작이 이루어지게 된다.These mouthguards are manufactured by obtaining accurate data on the condition of the oral cavity through an appropriate examination at the dentist, and then checking the position of the temporomandibular joint and occlusal condition during the processing process.
종래의 3D 프린팅으로 제조된 교정용 마우스 가드는 물성 변화가 없고 소재가 너무 단단하여, 임상에서 착용 시에 불편함을 비롯한 문제점이 많았고, 사용처도 제한적이었다.Orthodontic mouth guards manufactured through conventional 3D printing had no change in physical properties and the material was too hard, so they had many problems, including discomfort when worn in clinical practice, and their use was limited.
본 발명은 상기의 문제점을 해결하기 위해 안출된 것으로서, 본 발명의 목적은 온도 변화에 따라 물성이 변하는 3D 프린팅 소재를 제공하는 것이다. The present invention was devised to solve the above problems, and the purpose of the present invention is to provide a 3D printing material whose physical properties change with temperature changes.
본 발명의 다른 목적은 상기 3D 프린팅 소재로 제조되어, 구강 내에 편리하게 장착 가능한 교정용 마우스 가드를 제공하는 것이다.Another object of the present invention is to provide an orthodontic mouth guard that is manufactured from the 3D printing material and can be conveniently installed in the oral cavity.

No.
이하, 본 발명에서 사용되는 용어를 상세히 설명한다.Hereinafter, the terms used in the present invention will be described in detail.
본 발명에서 “스플린트(Splint)”는 수면 중 무의식적으로 일어나는 이갈이 습관을 방지할 수 있는 기구로, 상기 스플린트 기구는 위아래 치아가 맞물리지 않게 하여 치아가 마모되는 것을 막아주고, 저작근을 이완시켜주며, 턱관절에 무리가 가지 않게 돕는 역할을 한다. 본 발명에 따른 플렉서블 3D 프린팅 소재는 구강 내에서 온도가 변함에 따라 강도가 변하고 부드러워지므로, 상기 스플린트에 활용될 수 있다.In the present invention, “Splint” is a device that can prevent the habit of teeth grinding that occurs unconsciously during sleep. The splint device prevents the teeth from being worn by preventing the upper and lower teeth from engaging, relaxes the masticatory muscles, and relaxes the jaw muscles. It helps prevent stress on the joints. The flexible 3D printing material according to the present invention changes strength and becomes soft as the temperature changes in the oral cavity, so it can be used for the splint.
본 발명에서 “나이트 가드(Night guard)”는 위쪽 치아 또는 아래쪽 치아 중 한쪽에 장착하는 기구로, 치과의사의 판단 후 치아 배열 등의 여러 가지 여건을 고려하여 장착한다. 상기 나이트가드는 수면 시 치아에 사용하며 이갈이 증상을 완화시켜주고 치아 마모를 막아주는 역할을 한다. 상기 나이트가드는 제품 특성상 6시간 이상을 착용해야 하기 때문에, 구강 내에서 부드러운 소재로 제조되어야 한다.In the present invention, a “night guard” is a device that is installed on either the upper or lower teeth, and is installed after the dentist’s judgment and taking into consideration various conditions such as tooth arrangement. The night guard is used on teeth while sleeping and serves to relieve bruxism symptoms and prevent tooth wear. Because the night guard must be worn for more than 6 hours due to the nature of the product, it must be made of a material that is soft for the oral cavity.
본 발명에서 “템플릿(Template)”은 턱관절에 대한 압력을 줄여 턱관절증상의 개선을 유도하는 것에 더하여 상악을 뒤로 밀게 되어 경추부의 압력을 줄여주는 기구이다. 보편적인 스플린트의 높이보다 더 높은 장치를 사용하여 악구강계에서의 변화를 주변 두경부와 중추신경계 쪽으로 영향을 넓히는 기구이다. 사용자 스스로 입안에 사용 가능한 장치를 사용함으로 입원 등은 필요하지 않고 일상 생활이 가능하며, 하루에 6 내지 10시간 동안 장치를 사용하여 경추의 압력을 감소시킬 수 있다.In the present invention, the “Template” is a device that not only improves temporomandibular joint symptoms by reducing pressure on the temporomandibular joint, but also reduces pressure on the cervical region by pushing the upper jaw back. It is a device that uses a device higher than the height of a common splint to extend the effect of changes in the oral cavity system to the surrounding head and neck and central nervous system. By using a device that can be used in the mouth, the user can lead a normal life without the need for hospitalization, and can reduce the pressure on the cervical spine by using the device for 6 to 10 hours a day.
본 발명에서는 주위 환경 온도의 변화에 따라 민감하게 대응할 수 있는 응답성이 우수한 고분자를 합성하기 위해서 여러 개의 가지(branch)를 보유하는 동시에 분자량 분포가 일정한 거대분자를 제조하고 이의 가교 반응을 통해 네트워크 구조를 형성하는 화학적 가교방법을 이용할 수 있다.In the present invention, in order to synthesize a polymer with excellent responsiveness that can respond sensitively to changes in ambient temperature, a macromolecule having several branches and a constant molecular weight distribution is manufactured and a network structure is formed through a cross-linking reaction thereof. A chemical crosslinking method can be used to form .
폴리에스터 또는 폴리우레탄 기반 온도감응형 형상기억고분자는 온도에 감응하여 상(Phase)이 변화 하는 변이부분(Transition Segment)과 고분자에 강한 기계적 물성을 부여하는 경질 부분(Hard Segment)로 구성될 수 있으며, 상변이 메카니즘에 따라 유리전이(Glass Transition), 용융(Melting), 액정화(Liquid Crystallization) 등의 현상을 보유하는 화학구조를 변이 부분으로 사용할 수 있다.Polyester or polyurethane-based temperature-sensitive shape memory polymers can be composed of a transition segment that changes phase in response to temperature and a hard segment that provides strong mechanical properties to the polymer. , Depending on the phase change mechanism, a chemical structure that possesses phenomena such as glass transition, melting, and liquid crystallization can be used as a transition part.
전이부분으로 가장 적합한 후보로서 폴리에틸렌글리콜(Polyethylene glycol, PEG)을 선정하여 진행할 수 있으며, 이는 폴리에틸렌글리콜이 결정화가 가능하고 분자량에 따라 섭씨0~26도 사이에서 결정이 생성 되거나 용융되는 상전이현상을 보일 수 있기 때문이다. 저분자량PEG의 상전이 온도구간이 낮을지라도 상대분자 및 나노 핵과의 가교반응 후 형성되는 네트워크 고분자에서PEG 전이부분의 상전이 온도구간은 상승할 수 있다.Polyethylene glycol (PEG) can be selected as the most suitable candidate for the transition part. Polyethylene glycol is capable of crystallization and exhibits a phase transition phenomenon in which crystals are formed or melted between 0 and 26 degrees Celsius depending on the molecular weight. Because you can. Even though the phase transition temperature range of low molecular weight PEG is low, the phase transition temperature range of the PEG transition portion in the network polymer formed after the crosslinking reaction with the counterpart molecule and nano nucleus can increase.
이상 설명으로부터, 본 발명에 속하는 기술 분야의 당업자는 본 발명의 그 기술적 사상이나 필수적 특징을 변경하지 않고서 다른 구체적인 형태로 실시될 수 있다는 것을 이해할 수 있을 것이다.From the above description, those skilled in the art to which the present invention pertains will understand that the present invention can be implemented in other specific forms without changing its technical idea or essential features.
