Description
本創作係關於一種排齦線，尤指一種由一薄片捲繞成形的排齦線。The present invention relates to a sputum line, especially a sputum line formed by winding a sheet.
於牙科療程中，常需以特殊的方式將牙齦與牙齒之間撐開，該方式稱之為排齦。例如，當蛀牙位置靠近牙齦或牙齦與牙齒交界之下，則需要排齦以便補牙的進行；在製造假牙的過程中，因需完整印出牙體修磨後的牙齒邊緣(margin)，若該邊緣位於牙齦交界處或牙齦下方，亦需要進行排齦才可使印膜材料完整印出牙齒與牙齦交界處以下部分牙齒的形狀。在排齦的過程中，最常用的手法是將排齦線(gingival retraction cord)壓入牙齒與牙齦之間，使牙齒與牙齦分開，當要進行印模時會將排齦線抽出，讓牙齦邊緣暫時與牙齒分離騰出空間，使得牙齒在原本與牙齦交界的地方完全露出，以便於製做齒模時能夠完整印出牙齒的形狀而不受牙齦干擾。在將排齦線抽出時時常造成牙齦出血，若有出血則須先止血才能繼續印模，故較理想之排齦線應具備一定程度之韌度、變形能力，且以減少牙齦出血或萎縮及患者疼痛、不適感為佳。In the dental treatment, it is often necessary to open the gums between the teeth in a special way, which is called drainage. For example, when the position of the tooth is close to the gum or the boundary between the gum and the tooth, it is necessary to drain the tooth to make up the tooth; in the process of manufacturing the tooth, the tooth edge after the tooth is repaired is completely printed, if The edge is located at the junction of the gums or under the gums. It is also necessary to perform drainage so that the film material can completely print out the shape of the teeth below the junction of the teeth and the gums. In the process of sputum sputum, the most common method is to press the gingival retraction cord between the teeth and the gums to separate the teeth from the gums. When the impression is to be made, the sputum line will be pulled out and the gums will be removed. The edge temporarily separates from the teeth to make room for the teeth to be completely exposed at the junction with the gums, so that the shape of the teeth can be completely printed without being disturbed by the gums when the tooth mold is made. When the drainage line is taken out, it often causes bleeding of the gums. If there is bleeding, the blood must be stopped before the impression can be continued. Therefore, the ideal drainage line should have a certain degree of toughness and deformability, and reduce the bleeding or atrophy of the gums. The patient's pain and discomfort are better.
現有技術中的排齦線其材質通常為棉線或蠶絲，但具有不同線形成的方式，如使用單股抽絲法(spunretraction cord )、雙股搓捻法(twisted retraction cord)、編織法(braided retraction cord)及針織法(knitted retraction cord)等，因排齦之過程容易造成牙齦出血，為避免出血或滲液，有時會將排齦線浸泡於添加止血劑等化學藥劑後再進行使用。 The prior art retraction cord which is usually made of cotton or silk, but the embodiment is formed with a different line, such as the use of a single strand spinning method (spunretraction cord), double-strand twist method (twisted retraction cord), knitting (braided Retraction cord), knitted retraction cord, etc., may cause bleeding gums due to the process of sputum sputum. In order to avoid bleeding or exudation, the sputum line may be immersed in a chemical such as a hemostatic agent before use.
雙股搓捻法或編織法之排齦線為實心排齦線，相較於單股排齦線可達到較好之排齦效果，然因其為實心狀故變形能力有限，容易過於擠壓牙齦而導致牙齦出血；針織法之排齦線於斷面呈空心狀，具有較好的變形能力以配合牙齦與牙齒之間隙大小，然針織法之排齦線與牙齒較粗糙處摩擦時容易造成出絲或斷裂之問題，且於排齦結束後去除排齦線時容易造成牙齦出血，造成印模的誤差，進而影響後續齒模製作之精準度與增加臨床治療的複雜度；含有止血成分等化學藥劑之排齦線並非適用於所有患者，且止血劑多呈酸性，容易侵蝕牙齒。前述現有技術之排齦線與牙齦皆呈線狀接觸，故接觸點受壓力較大，容易造成患者不適或疼痛感，嚴重時會造成患者之牙齦萎縮退化等永久性傷害。The double-twisting method or the weaving method of the weaving method is a solid drainage line, which can achieve better drainage effect than the single-row drainage line. However, because it is solid, the deformation ability is limited, and it is easy to be too squeezed. The gums cause bleeding of the gums; the sputum line of the knitting method has a hollow shape in the cross section, and has a good deformability to match the gap between the gums and the teeth. However, the knitting line of the knitting method is likely to cause friction when the teeth are rough. The problem of silk or breakage, and the removal of the sputum line after the end of sputum sputum is likely to cause bleeding of the gums, resulting in errors in the impression, which in turn affects the accuracy of subsequent tooth mold making and increases the complexity of clinical treatment; contains hemostatic components, etc. The chemical repellent line is not suitable for all patients, and the hemostatic agent is mostly acidic and easily erodes the teeth. The above-mentioned prior art drainage line and the gums are in linear contact, so the contact point is subjected to a large pressure, which is likely to cause discomfort or pain to the patient, and in severe cases, the patient may suffer from permanent damage such as atrophy of the gums.
鑒於現有技術實心排齦線塑形能力差、空心針織的排齦線易分絲斷裂，且易導致牙齦出血、萎縮以及造成患者疼痛不適之缺點，故本創作之目的在於提供一種排齦線，藉由該排齦線為非實心、非編織之方式成形，且表面光滑可達到排齦線具有高可塑性、不分絲斷裂及降低排齦過程的出血，使得假牙印模或其他療程可順利進行，同時可降低患者不適之排齦效果。In view of the fact that the prior art solid sputum line has poor shaping ability, the hollow knitted sputum line is easy to split, and easily causes bleeding and atrophy of the gums and causes pain and discomfort to the patient, the purpose of the present invention is to provide a sputum line. The sputum line is formed in a non-solid, non-woven manner, and the surface is smooth, and the sputum line has high plasticity, no wire breakage and reduced bleeding during the sputum removal process, so that the false impression or other treatment can be smoothly performed. At the same time, it can reduce the patient's discomfort.
為了達到上述目的，本創作提供一種排齦線，其具可撓性，該排齦線係由一薄片捲繞而成且呈非實心多層長條狀，該薄片包含一第一側邊及一第二側邊；該第一側邊與該第二側邊相對且相平行；其中該排齦線係由該薄片之第一側邊往第二側邊之方向包覆捲繞成形。In order to achieve the above object, the present invention provides a retracting cord which is flexible and has a non-solid multi-layered strip which is formed by a sheet and includes a first side and a a second side; the first side is opposite to and parallel to the second side; wherein the winding line is wrapped and formed by the first side of the sheet toward the second side.

依據本創作，所述之「外徑」係指該排齦線外緣之兩相對位置之直線距離。According to the present invention, the "outer diameter" refers to the linear distance between the two opposite positions of the outer edge of the retraction line.
較佳的，所述之該排齦線之側向延展性大於其軸向延展性。Preferably, the lateral ductility of the retraction line is greater than its axial ductility.
更佳的，所述之該薄片更包含一摺邊，該摺邊係由該薄片靠近該第一側邊之位置彎摺所形成，且該摺邊與該第一側邊平行。More preferably, the sheet further comprises a hem which is formed by bending the sheet near the first side, and the hem is parallel to the first side.
更佳的，所述之該薄片係由聚四氟乙烯纖維或膨體聚四氟乙烯纖維趨於平行排列所形成，且聚四氟乙烯纖維或膨體聚四氟乙烯纖維之方向與該薄片之該第一側邊及該第二側邊平行。More preferably, the sheet is formed by PTFE fibers or expanded polytetrafluoroethylene fibers tending to be arranged in parallel, and the direction of the polytetrafluoroethylene fibers or the expanded polytetrafluoroethylene fibers and the sheet are The first side and the second side are parallel.
本創作所述之排齦線為薄片捲繞而成的非實心體，可解決現有技術之實心排齦線可塑性低且容易造成壓力過於集中導致牙齦出血與疼痛等問題；且相較於針織空心狀或編織實心狀成形而表面粗糙的傳統排齦線，本創作之排齦線呈平滑表面，且其捲繞的層狀結構而使其有很大的變形能力，故容易壓入患者牙齦與牙齒之間的間隙，且在排齦線壓入牙齒與牙齦之間時，因該排齦線能適當形變而與牙齦呈面狀接觸，可使牙齦均勻受壓進而降低牙齦出血或患者之不適，本創作之排齦線不易分絲或出屑，可提高齒模製作之完整性，在拉除排齦線時也較現有技術之排齦線不容易出血。The sputum line described in the present invention is a non-solid body formed by winding a sheet, which can solve the problems of low plasticity of the solid sputum line of the prior art and easy to cause excessive pressure to cause bleeding and pain of the gum; and compared with the knitting hollow The traditional sputum line which is shaped like a solid shape and has a rough surface.
