Description

이갈이 방지용 마우스피스 및 마우스피스 제작방법{Mouthpiece for preventing teeth grinding and Method for manufacturing the same}Mouthpiece for preventing teeth grinding and Method for manufacturing the same}

본 발명은 이갈이 방지용 마우스피스에 관한 것으로서, 보다 상세하게는, 3D프린터를 이용해 프린팅 방식으로 제작되므로 칫수 정밀성이 뛰어나 치아(齒牙)와의 안정적인 결합을 유지하고, 실리콘과 레진의 이중구조를 가져 치아에 무리를 주지 않으면서도 내구성이 양호한, 이갈이 방지용 마우스피스 및 마우스피스 제작방법에 관한 것이다.The present invention relates to a mouthpiece for preventing bruxism, and more particularly, since it is manufactured by a printing method using a 3D printer, it has excellent dimensional accuracy, maintains stable bonding with teeth, and has a dual structure of silicone and resin to teeth It relates to a mouthpiece for preventing bruxism and a method for manufacturing the mouthpiece, which has good durability without putting too much strain on teeth.

수면 중 본인도 모르게 이를 갈거나 강하게 악무는 이갈이는, 수면장애의 일종으로서, 치아는 물론 턱관절 등에 악영향을 미친다. 이갈이의 원인은 다양하며, 가령, 스트레스나, 영양부족, 알러지나, 대사장애, 뇌질환 등에 의해 발생하는 것으로 여겨지고 있다.Grinding teeth or grinding teeth strongly during sleep is a type of sleep disorder that adversely affects teeth as well as temporomandibular joints. There are various causes of bruxism, and it is believed to be caused by, for example, stress, malnutrition, allergy, metabolic disorder, brain disease, and the like.

이갈이가 계속되면, 치아가 점차 마모됨은 물론 치아 배열 자체도 틀어져 개방교합이나 안면비대칭에 이를 수 있고, 혀나 볼의 내측 점막에 압흔이 생기며, 턱관절에도 이상이 발생하여 퇴행성 골관절염이 나타날 수 있다. If bruxism continues, the teeth gradually wear out and the arrangement of the teeth itself is distorted, which can lead to open bite or facial asymmetry, indentations on the inner mucous membrane of the tongue or cheeks, and abnormalities in the temporomandibular joint, resulting in degenerative osteoarthritis.

이러한 문제 이외에도, 이갈이는 주변 사람들을 불편하게 하는 소음을 발생한다. 가령 한 공간에서 여러 명이 수면을 취할 때, 한 사람이 이를 갈면, 이 가는 소리가 여러 사람의 숙면을 방해하는 것이다.In addition to these problems, bruxism creates noise that makes people around you uncomfortable. For example, when several people are sleeping in one space, if one person grinds their teeth, the sound of teeth grinding disturbs the sound sleep of many people.

상기한 이갈이의 문제를 해결하기 위한 기구로서, 수면 시 입에 무는 마우스피스가 알려져 있다. 마우스피스는 합성수지로 성형 제작되며 자기 전에 윗니와 아랫니에 끼워진다.[0003] As a device for solving the problem of bruxism, a mouthpiece worn in the mouth during sleep is known. The mouthpiece is molded from synthetic resin and is fitted to the upper and lower teeth before going to bed.

그런데 종래의 마우스피스는, 그 제작공정이 번거롭고 제작에 시간이 오래 걸린다는 단점을 갖는다. (제작 시간은 보통 일주일 이상 소요된다.) 이를테면, 마우스피스를 제작하기 위해, 고무나 알지네이트로 환자의 인상을 채득하고, 채득인상을 이용해 석고로 치아의 모양을 만든 후, 이를 기공소로 보내어 레진으로 마우스피스를 성형하고 후가공을 하는 여러 단계를 거쳐야 하므로, 총 제작 시간이 오래 걸리는 것이다.However, the conventional mouthpiece has disadvantages in that the manufacturing process is cumbersome and takes a long time to manufacture. (Production time usually takes more than a week.) For example, to manufacture a mouthpiece, a patient's impression is taken with rubber or alginate, and after using the impression to make the shape of the tooth with plaster, it is sent to a laboratory to be made into resin. Since the mouthpiece must be molded and go through several steps of post-processing, the total manufacturing time is long.

또한 종래 마우스피스는 경질의 레진으로 제작되며 두께가 두꺼워, 착용 시 이물감이 크고 불편하다. 어린이의 경우 마우스피스를 착용한 상태로 잠자리에 들더라도, 수면 중 마우스피스를 무의식적으로 뱉어내는 경우가 많다.In addition, the conventional mouthpiece is made of hard resin and has a thick thickness, causing a large foreign body sensation and discomfort when worn. In the case of children, even if they go to bed with the mouthpiece on, they often unconsciously spit out the mouthpiece during sleep.

이갈이 방지용 마우스피스에 관한 배경이 되는 기술로서, 국내 등록특허공보 제10-1782093호 (코골이 및 이갈이 방지기구)가 개시된 바 있다. As a background technology for a mouthpiece for preventing bruxism, Korean Registered Patent Publication No. 10-1782093 (mechanism for preventing snoring and bruxism) has been disclosed.

이하, 본 발명에 따른 하나의 실시예를 첨부된 도면을 참조하여 보다 상세히 설명하기로 한다.Hereinafter, one embodiment according to the present invention will be described in more detail with reference to the accompanying drawings.

본 발명의 이갈이 방지용 마우스피스는, 이갈이 환자가 수면을 취할 때 사용하는 것으로서, 3D프린팅 방식으로 제작되는 만큼 두께가 얇아 이물감이 없고 치아에 대한 밀착성이 양호하다. 또한 내부에는 말랑말랑한 실리콘 라이너가 구비되어 치아에 부담이 없으며, 외측은 레진으로 이루어지므로 내구성이 우수하다.The mouthpiece for preventing bruxism of the present invention is used when a bruxism patient sleeps, and is thin enough to be manufactured by a 3D printing method, so there is no foreign body sensation and good adhesion to the teeth. In addition, a soft silicone liner is provided on the inside so that there is no burden on the teeth, and the outside is made of resin, so durability is excellent.

도 1은 본 발명의 일 실시예에 따른 이갈이 방지용 마우스피스(10)를 도시한 일부 절제 사시도이고, 도 2는 도 1의 A-A선 단면도이며, 도 3은 도 1의 B-B선 단면도이다.1 is a partially cut away perspective view of a mouthpiece 10 for preventing bruxism according to an embodiment of the present invention, FIG. 2 is a cross-sectional view taken along line A-A of FIG. 1, and FIG. 3 is a cross-sectional view taken along line B-B of FIG.

도시한 바와 같이, 본 실시예에 따른 이갈이 방지용 마우스피스(10)는, 윗니커버(20)와 아랫니커버(30)로 구성된다. 도 1에서는 윗니커버(20)와 아랫니커버(30)를 모두 나타내었으나, 환자의 치아 상태에 따라, 윗니커버(20)만 필요하다거나 아랫니커버(30)만 필요할 경우, 윗니커버(20)나 아랫니커버(30)만 사용함은 물론이다.As shown, the mouthpiece 10 for preventing bruxism according to the present embodiment is composed of an upper tooth cover 20 and a lower tooth cover 30. 1 shows both the upper tooth cover 20 and the lower tooth cover 30, but depending on the condition of the patient's teeth, if only the upper tooth cover 20 or only the lower tooth cover 30 is required, the upper tooth cover 20 or Of course, only the lower teeth cover 30 is used.

윗니커버(20) 및 아랫니커버(30)는, 실리콘과 레진과 수용성 PVA(폴리비닐알코올)을 재료로 하여 프린팅 방식으로 성형 제작된다. The upper tooth cover 20 and the lower tooth cover 30 are molded and manufactured using a printing method using silicone, resin, and water-soluble PVA (polyvinyl alcohol) as materials.

윗니커버(20)는, 커버본체(21)와 라이너(23)의 이중 구조를 갖는다. 커버본체(21)는, 윗니의 안쪽면과 바깥쪽에 밀착하는 벽부(21a)와, 벽부(21a)의 하단에 일체를 이루고 윗니의 저면(음식물을 씹는 저작면)을 커버하는 눌림부(21b)를 갖는다. 눌림부(21b)는 윗니와 아랫니의 교합 시 아랫니커버(30)에 접한다. 윗니커버(20)에는 공간부(20a)가 마련된다. 공간부(20a)는 써포트(61)가 제거된 후의 남는 공간으로서 윗니를 수용 고정한다. The upper teeth cover 20 has a dual structure of a cover body 21 and a liner 23. The cover body 21 includes a wall portion 21a that adheres to the inside and outside of the upper teeth, and a pressing portion 21b integrally formed with the lower end of the wall portion 21a and covering the bottom surface of the upper teeth (the chewing surface for chewing food). have The pressing portion 21b comes into contact with the lower teeth cover 30 when the upper teeth and the lower teeth mate. Upper tooth cover 20 is provided with a space portion (20a). The space portion 20a is a remaining space after the support 61 is removed and accommodates and fixes the upper teeth.

이러한 커버본체(21)는 레진으로 제작될 수 있으며, 특히 POM(폴리옥시메틸렌)이나, PLA(Poly Lactic Acid)로 제작 가능하다.The cover body 21 may be made of resin, in particular, POM (polyoxymethylene) or PLA (poly lactic acid).

라이너(23)는, 눌림부(21b)의 안쪽면에 일체로 형성되는 부분으로서 치아의 저작면에 밀착한다. 라이너(23)는 실리콘으로 성형 제작되며 말랑말랑한 물성을 가져 치아에 부담을 주지 않는다.The liner 23 is integrally formed on the inner surface of the pressing portion 21b and adheres to the chewing surface of the teeth. The liner 23 is made of silicone and has soft physical properties so that it does not burden the teeth.

아랫니커버(30)는, 환자의 아랫니에 끼우는 것으로서, 커버본체(31)와 라이너(33)로 구성된다. 커버본체(31)와 라이너(33)의 재질은 윗니커버의 커버본쳬(21) 및 라이너(23)와 동일하다.The lower teeth cover 30 is fitted to the patient's lower teeth and is composed of a cover body 31 and a liner 33. The material of the cover body 31 and the liner 33 is the same as the cover body 21 and the liner 23 of the upper teeth cover.

커버본체(31)는, 아랫니의 안쪽면과 바깥쪽면에 접하는 벽부(31a), 벽부의 상단부에 일체를 이루며 아랫니의 저작면을 커버하는 눌림부(31b)를 갖는다. 또한 커버본체(31)에는 공간부(30a)가 형성되는데, 공간부(30a)에는 아랫니가 끼워진다.The cover body 31 has a wall portion 31a in contact with the inner and outer surfaces of the lower teeth, and a pressing portion 31b integrally formed with the upper end of the wall portion and covering the chewing surface of the lower teeth. In addition, a space portion 30a is formed in the cover body 31, and the lower teeth are fitted into the space portion 30a.

라이너(33)는, 눌림부(31b)의 저면에 일체로 형성되며, 아랫니의 저작면에 밀착한다. 실리콘으로 이루어지는 라이너(33)는 탄성 변형 가능하므로 치아에 부담을 주지 않는다.The liner 33 is integrally formed on the bottom surface of the pressing portion 31b and closely adheres to the chewing surface of the lower teeth. Since the liner 33 made of silicone is elastically deformable, it does not burden the teeth.

상기한 윗니커버(20) 및 아랫니커버(30)에 있어서, 벽부(21a,31a)와 눌림부(21b,31b)의 두께는 필요에 따라 다르게 설계할 수 있다. 이러한 설계 적용은 후술할 데이터처리단계(103)와 치아모델링단계(105) 시 소프트웨어를 통해 얼마든지 구현 가능하다.In the upper teeth cover 20 and lower teeth cover 30 described above, the thicknesses of the wall portions 21a and 31a and the pressing portions 21b and 31b may be designed differently as needed. This design application can be implemented as much as possible through software during the data processing step 103 and the tooth modeling step 105 to be described later.

도 4 및 도 5는 본 발명의 일 실시예에 따른 이갈이 방지용 마우스피스의 변형 예를 설명하기 위한 단면도로서, 도 4는 윗니커버(20)의, 도 5는 아랫니커버(30)의 단면도이다.4 and 5 are cross-sectional views for explaining a modified example of a mouthpiece for preventing bruxism according to an embodiment of the present invention. FIG. 4 is a cross-sectional view of the upper tooth cover 20 and FIG. 5 is the lower tooth cover 30.

이하, 상기한 도면부호와 동일한 도면부호는 동일한 기능의 동일한 부재를 가리킨다.Hereinafter, the same reference numerals as the above reference numerals indicate the same members having the same functions.

도 4를 참조하면, 커버본체(21)의 내측에 위치하는 라이너(23)가, 측면부호부(23a)와 저작면보호부(23b)로 이루짐을 알 수 있다. 측면보호부(23a)는 윗니의 안쪽면 및 바깥쪽면을 커버하고, 저작면보호부(23b)는 윗니의 저작면을 커버한다. Referring to FIG. 4 , it can be seen that the liner 23 located inside the cover body 21 includes a side code portion 23a and a chewing surface protection portion 23b. The side protection portion 23a covers the inner and outer surfaces of the upper teeth, and the chewing surface protection portion 23b covers the chewing surface of the upper teeth.

또한 도 5에 도시한 것처럼, 아랫니커버(30)의 공간부(30a) 내에 위치하는 라이너(33)는 측면부호부(33a)와 저작면보호부(33b)로 구성된다. 측면보호부(33a)는 아랫니의 안쪽면과 바깥쪽면을 커버한다. 또한 저작면보호부(33b)는 아랫니의 저작면에 밀착한다.In addition, as shown in FIG. 5, the liner 33 located in the space portion 30a of the lower tooth cover 30 is composed of a side code portion 33a and a chewing surface protection portion 33b. The side protection portion 33a covers the inner and outer surfaces of the lower teeth. In addition, the chewing surface protection unit 33b adheres to the chewing surface of the lower teeth.

상기와 같이 윗니와 아랫니를 라이너(23)로 완전히 감싸므로 윗니와 아랫니를 보다 안정적으로 보호할 수 있다.As described above, since the upper and lower teeth are completely covered with the liner 23, the upper and lower teeth can be more stably protected.

도 6은 본 발명의 일 실시예에 따른 마우스피스(10)의 작용을 설명하기 위한 부분 단면도이다. 6 is a partial cross-sectional view for explaining the operation of the mouthpiece 10 according to one embodiment of the present invention.

도 6에는 윗니(41)에 윗니커버(20)를, 아랫니(43)에 아랫니커버(30)를 장착한 모습을 나타내었다. 하지만, 환자의 상태에 따라 아랫니커버(30)만 끼우거나 윗니커버(20)만 끼울 수 있음 물론이다.6 shows a state in which the upper teeth cover 20 is attached to the upper teeth 41 and the lower teeth cover 30 to the lower teeth 43. However, depending on the patient's condition, only the lower teeth cover 30 or only the upper teeth cover 20 can be fitted.

도시한 바와 같이, 윗니커버(20)의 커버본체(21)와 아랫니커버(30)의 커버본체(31)가 상호 밀착하고 있다. 또한 각 커버본체(21,31) 내부의 라이너(23,33)는 윗니와 아랫니를 탄력적으로 지지한다. 라이너(23,33)는 탄성 변형 가능하므로, 환자가 수면 중 이를 세게 물 경우, 수축하며, 윗니와 아랫니의 부담을 경감시킨다.As shown, the cover body 21 of the upper tooth cover 20 and the cover body 31 of the lower tooth cover 30 are in close contact with each other. In addition, the liners 23 and 33 inside each cover body 21 and 31 elastically support the upper and lower teeth. Since the liners 23 and 33 are elastically deformable, when a patient bites them hard while sleeping, they contract and reduce the burden on the upper and lower teeth.

라이너(23,33)가 없다면, 사용자가 이를 악물 때의 힘이 그대로 치아와 잇몸으로 전달되고, 이러한 습관이 오래되면 턱관절 장애가 발생하며, 저작근 등의 얼굴 근육에 힘이 들어가게 된다. 마우스피스를 착용하나 마나 한 것이 되는 것이다.Without the liners 23 and 33, the force when the user bites the teeth is transmitted to the teeth and gums as it is, and if this habit becomes old, temporomandibular joint disorders occur and force enters the facial muscles such as the masticatory muscles. Even if you wear a mouthpiece, it becomes a mana.

또한 커버본체(21,31)는 라이너(23,33)를 보호하는 역할을 한다. 가령, 커버본체(21,31) 없이, 위아래 라이너(23,33)가 서로 접한 상태로 이갈이가 시작되면, 라이너(23,33)가 밀착한 상태로 좌우방향으로 밀리며 찢어지게 된다. 커버본체(21,31)는 어느 정도의 강성을 갖는 레진으로 제작되므로 이갈이가 진행되는 동안 가해지는 힘에 의해 손상되지 않는다. In addition, the cover bodies 21 and 31 serve to protect the liners 23 and 33 . For example, if bruxism starts in a state where the upper and lower liners 23 and 33 are in contact with each other without the cover body 21 and 31, the liners 23 and 33 are pushed in the left and right directions while being in close contact with each other and torn. Since the cover bodies 21 and 31 are made of resin having a certain degree of rigidity, they are not damaged by force applied during bruxism.

도 7은 본 발명의 일 실시예에 따른 이갈이 방지용 마우스피스를 프린팅 제작하기 위한 3D프린터(50)를 참고적으로 도시한 정면도이다. 본 실시예의 마우스피스의 제작에 사용되는 3D프린터는 FDM(Fused deposition modeling) 방식이다. 7 is a front view showing, for reference, a 3D printer 50 for printing a mouthpiece for preventing bruxism according to an embodiment of the present invention. The 3D printer used to manufacture the mouthpiece of this embodiment is a fused deposition modeling (FDM) method.

도시한 바와 같이, 3D프린터(50)는, 프린팅공간(51a)을 제공하는 캐비닛(51), 프린팅공간(51a)의 하측부에 고정되는 테이블(52), 테이블(52) 상부에 수평으로 설치되며 승강 가능한 승강레일(53), 승강레일(53)에 지지되며 수평방향 왕복 운동하는 노즐유니트(55)로 구성된다. As shown, the 3D printer 50 is installed horizontally on a cabinet 51 providing a printing space 51a, a table 52 fixed to the lower part of the printing space 51a, and an upper part of the table 52 It is composed of an elevating rail 53 and a nozzle unit 55 supported on the elevating rail 53 and reciprocating in the horizontal direction.

노즐유니트(55)는, 외부로부터 공급되는 소재 필라멘트, 즉, 실리콘과 레진 필라멘트를 통과시키면서 녹여 하부로 출력한다. 용융된 상태로 출력되는 소재는 테이블(52) 위에 마우스피스(10)를 프린팅한다.The nozzle unit 55 melts material filaments supplied from the outside, that is, silicon and resin filaments while passing them, and outputs them to the lower part. The material output in a molten state prints the mouthpiece 10 on the table 52 .

노즐유니트(55)에는, 실리콘노즐(55a), 레진노즐(55c), PVA노즐(55e), UV조사부(55f)가 구비된다. 실리콘노즐(55a)은 실리콘 필라멘트를 배출하는 노즐이고, 레진노즐(55c)은 레진필라멘트를, PVA노즐(55e)은 PVA필라멘트를 용융 배출하는 노즐이다. 노즐 자체의 구조나 작동 방식은 일반적인 것이므로 더 이상의 설명은 생략한다.The nozzle unit 55 includes a silicon nozzle 55a, a resin nozzle 55c, a PVA nozzle 55e, and a UV irradiation unit 55f. The silicon nozzle 55a is a nozzle that discharges the silicon filament, the resin nozzle 55c is a nozzle that melts and discharges the resin filament, and the PVA nozzle 55e is a nozzle that melts and discharges the PVA filament. Since the structure or operation method of the nozzle itself is general, further description is omitted.

UV조사부(55f)는 UV광을 출력하는 광출력부로서, 실리콘노즐(55a)을 통해 유출된 용융상태의 실리콘에 UV를 조사하여 실리콘을 UV중합시킨다. 알려진 바와 같이, 용융상태의 실리콘 자체는 점성이 높아 끈적끈적 하므로, 정밀한 프린팅이 이루어지지 않을 수 있다. 이러한 이유로 용융된 실리콘에 UV광을 조사하여 실리콘을 중합시키는 것이다. 실리콘을 중합시키면 접착성이 향상되고 흘러내리지 않아 정확한 적층 두께로 적층이 가능하다. The UV irradiation unit 55f is a light output unit that outputs UV light, and irradiates the molten silicon flowing out through the silicon nozzle 55a with UV to UV polymerize the silicon. As is known, since silicon itself in a molten state has high viscosity and is sticky, precise printing may not be achieved. For this reason, the molten silicon is irradiated with UV light to polymerize the silicon. When silicone is polymerized, adhesion is improved and it is possible to laminate with an accurate laminate thickness because it does not flow.

도 8은 본 발명의 일 실시예에 따른 마우스피스 제작방법을 설명하기 위한 블록도이고, 도 9는 3D프린팅 과정을 도식적으로 나타내 보인 도면이다.8 is a block diagram for explaining a mouthpiece manufacturing method according to an embodiment of the present invention, and FIG. 9 is a diagram schematically showing a 3D printing process.

본 실시예에 따른 마우스피스 제작방법은, 3D프린팅 기술을 적용한 것으로서, 마우스피스의 총 제작시간은 몇 시간 정도 소요될 뿐이다. 종전에 일주일 이상 소요되던 제작 시간을 크게 단축시킬 수 있는 것이다. The mouthpiece manufacturing method according to the present embodiment is applied with 3D printing technology, and the total manufacturing time of the mouthpiece takes only a few hours. This can drastically reduce production time, which previously took more than a week.

도시한 바와 같이, 본 실시예에 따른 마우스피스 제작방법은, 스캐닝단계(101), 데이터처리단계(103), 치아모델링단계(105), 3D프린팅단계(107), 후처리단계(109)를 포함한다. As shown, the mouthpiece manufacturing method according to this embodiment includes a scanning step 101, a data processing step 103, a tooth modeling step 105, a 3D printing step 107, and a post-processing step 109. include

스캐닝단계(101)는, 치과용 스캐너를 이용해 환자의 치아 및 잇몸을 스캐닝 하는 과정이다. 스캐너 자체는 치과의사에 의해 다루어지는 일반적인 촬영 장비이다. 스캐너가 촬영한 내용은, 스캐너 장비 자체의 소프트웨어를 통해 모니터에 일차적으로 또한 실시간으로 디스플레이 된다. 의사는 모니터를 통해, 현재 스캐닝 되고 있는 치아와 잇몸의 모습을 확인할 수 있다.The scanning step 101 is a process of scanning the patient's teeth and gums using a dental scanner. The scanner itself is a common imaging device handled by dentists. The content photographed by the scanner is displayed primarily and in real time on the monitor through the software of the scanner device itself. The doctor can check the state of the currently scanned tooth and gum through the monitor.

데이터처리단계(103)는, 스캐닝단계를 통해 얻은 영상 정보를 데이터화하는 단계이다. 데이터처리단계(103)를 통해, 스캔 영상 정보가, 3D프린터를 구동하는 소프트웨어에 의해 편집 될 수 있는 상태가 된다.The data processing step 103 is a step of transforming the image information obtained through the scanning step into data. Through the data processing step 103, the scan image information becomes a state in which it can be edited by software driving the 3D printer.

치아 모델링단계(105)는, 데이터처리단계(103)를 통해 확보된 데이터를 기초로, 컴퓨터상에서, 환자의 치아 모양에 대응하는 마우스피스의 3차원 형상을 구현하는 과정이다. 말하자면, 모델링 소프트웨어를 이용해, 도 1에 도시한 마우스피스(10)의 모양을 구현하는 것이다. The tooth modeling step 105 is a process of implementing a three-dimensional shape of a mouthpiece corresponding to the patient's tooth shape on a computer based on the data obtained through the data processing step 103 . In other words, the shape of the mouthpiece 10 shown in FIG. 1 is implemented using modeling software.

3D프린팅단계(107)는, 3D프린터(50)를 이용해, 실리콘, 레진, PVA를 재료로 삼아, 마우스피스(10)를 실제 제작하는 과정이다. 위에 설명한 바와 같이, 본 실시예의 마우스피스(10)는 레진과 실리콘의 이중 구조를 갖는다. 3D프린팅단계(107) 자체의 세부 과정은 후술하기로 한다.The 3D printing step 107 is a process of actually manufacturing the mouthpiece 10 using the 3D printer 50 and using silicon, resin, and PVA as materials. As described above, the mouthpiece 10 of this embodiment has a dual structure of resin and silicon. A detailed process of the 3D printing step 107 itself will be described later.

후처리단계(109)는, 3D프린팅단계(107)를 통해 형성된 써포트(도 9e의 61)를 녹여 제거하는 과정이다.The post-processing step 109 is a process of melting and removing the support (61 in FIG. 9E) formed through the 3D printing step 107.

상기 후처리단계(109)를 통해 마우스피스(10)의 제작과정을 마친다.Through the post-processing step 109, the manufacturing process of the mouthpiece 10 is completed.

도 9를 참조하여 3D프린팅 과정을 따로 설명하기로 한다. 도 9는 도 2에 도시한 윗니커버(20)를 제작하는 모습을 순차적으로 도시하였다. 하지만 도 3의 아랫니커버(30)의 제작 과정도 동일하다.A 3D printing process will be separately described with reference to FIG. 9 . FIG. 9 sequentially shows how to manufacture the upper tooth cover 20 shown in FIG. 2 . However, the manufacturing process of the lower teeth cover 30 of FIG. 3 is also the same.

먼저 도 9a에 도시한 바와 같이, 테이블(52)의 상부에 써포트(61)와 벽부(21a)를 프린팅 하기 시작한다. 프린팅을 위해 노즐유니트(55)를 3차원 운동시켜야 하는 것은 당연하며, 이러한 사항은 일반적인 것이므로 프린터의 작동 자체에 대한 설명은 생략하기로 한다.First, as shown in FIG. 9A, the support 61 and the wall portion 21a are printed on the top of the table 52. It is natural that the nozzle unit 55 should be moved in three dimensions for printing, and since this is a general description of the operation of the printer itself, it will be omitted.

써포트(61)와 벽부(21a)를 계속적으로 적층하여, 써포트(61)가 도 9b에 도시한 바와 같이, 설계된 높이에 도달하였다면, 써포트(61)의 상부에 라이너(23)를 적층한다. 즉, 써포트(61)에 실리콘을 프린팅하고 UV광을 조사하여 라이너층을 만드는 것이다. 이 때 라이너(23)의 두께만큼 벽부(21a)도 높이 올린다.(도 9c 참조)When the support 61 and the wall portion 21a are continuously laminated and the support 61 reaches the designed height as shown in FIG. 9B, the liner 23 is laminated on top of the support 61. That is, the liner layer is made by printing silicon on the support 61 and irradiating UV light. At this time, the wall portion 21a is raised as high as the thickness of the liner 23 (see FIG. 9c).

라이너(23)의 적층이 완료되었다면 라이너(23)의 상부에 눌림부(21b)를 적층한다. 위에 설명한 바와 같이, 벽부(21a)와 눌림부(21b)는 레진으로 이루어진다. 눌림부(21b)의 적층이 완료되면 도 9d의 상태가 된다.When the stacking of the liner 23 is completed, the pressing portion 21b is stacked on top of the liner 23 . As described above, the wall portion 21a and the pressing portion 21b are made of resin. When the stacking of the pressing portion 21b is completed, the state shown in FIG. 9D is obtained.

이어서 프린팅된 결과물을 테이블(52)로부터 떼어낸 후 내부의 써포트(61)를 제거한다. 써포트(61)는 수용성 PVA로 이루어진 것이므로, 결과물을 물에 넣고 써포트(61)를 녹인다. 이 과정은 위에 설명한 후처리단계(109)에 해당한다. 써포트(61)를 제거하면, 도 9f에 도시한 바와 같이, 공간부(20a)가 형성된 윗니커버(20)가 만들어진다.Then, after the printed result is removed from the table 52, the internal support 61 is removed. Since the support 61 is made of water-soluble PVA, the resulting product is put into water and the support 61 is dissolved. This process corresponds to the post-processing step 109 described above. When the support 61 is removed, as shown in FIG. 9F, an upper tooth cover 20 having a space portion 20a is formed.

도 10a 내지 도 10f는 도 4에 도시한 윗니커버(20) 제작방법을 설명하기 위한 도면이다. 도 5의 아랫니커버(30)의 제작 방법도 동일하다.10a to 10f are diagrams for explaining a method of manufacturing the upper tooth cover 20 shown in FIG. 4 . The manufacturing method of the lower teeth cover 30 of FIG. 5 is also the same.

먼저, 도 10a에 도시한 바와 같이, 테이블(52) 위에, 써포트(61), 측면부호부(23a), 벽부(21a)를 쌓아 올리기 시작한다. 측면부호부(23a)는 실리콘으로 이루어지므로 측면부호부(23a)를 프린팅할 때에는 UV광을 동시에 조사한다.First, as shown in FIG. 10A, on the table 52, the support 61, the side code portion 23a, and the wall portion 21a are started to be piled up. Since the side code portion 23a is made of silicon, UV light is simultaneously irradiated when printing the side code portion 23a.

써포트(61)와 측면보호부(23a)와 벽부(21a)를 계속적으로 적층하여, 써포트(61)가 도 10b에 도시한 바와 같이, 설계된 높이에 도달하였다면, 써포트(61)의 상부에 저작면보호부(23b)를 적층한다. 또한 이 때, 저작면보호부(23b)의 두께 만큼 벽부(21a)도 높이 올린다.When the support 61, the side protection part 23a, and the wall part 21a are continuously stacked and the support 61 reaches the designed height, as shown in FIG. 10B, the chewing surface is placed on the top of the support 61. The protection part 23b is laminated. Also at this time, the wall portion 21a is raised as high as the thickness of the chewing surface protection portion 23b.

저작면보호부(23b)의 적층이 완료되었다면 저작면보호부(23b)의 상부에 눌림부(21b)를 적층한다. 위에 설명한 바와 같이, 벽부(21a)와 눌림부(21b)는 레진으로 이루어진다. 눌림부(21b)의 적층이 완료되면 도 10d의 상태가 된다.When the lamination of the chewing surface protection part 23b is completed, the pressing part 21b is stacked on top of the chewing surface protection part 23b. As described above, the wall portion 21a and the pressing portion 21b are made of resin. When the stacking of the pressing portion 21b is completed, the state shown in FIG. 10D is obtained.

이어서 프린팅된 결과물을 테이블(52)로부터 떼어낸 후 내부의 써포트(61)를 제거한다. 써포트(61)를 제거하면, 도 10f에 도시한 바와 같이, 공간부(20a)가 형성된 윗니커버(20)가 완성된다. Then, after the printed result is removed from the table 52, the internal support 61 is removed. When the support 61 is removed, as shown in FIG. 10F, the upper tooth cover 20 in which the space portion 20a is formed is completed.
