Abstract
Description
本發明係有關於一種排齦材料，特別是有關於可藉由光照射固化之排齦材料。 The present invention relates to a gingival retraction material, in particular to a gingival retraction material that can be cured by light irradiation.
排齦程序是一般在牙科臨床上，將病患牙齦溝暫時性地水平推開擴大後用以進行印模操作的先前程序。傳統中較常用排齦線(Gingival retraction cords)的方式，以機械力量擠壓排齦線入牙齦溝內，使牙齦溝水平擴大。然而，排齦線的操作需要相當高度的技巧才能將排齦線順利地填入牙齦溝中，且一般單顆牙齒操作約需要7-10分鐘。因此，排齦線在操作上難度高、費時，此外，也需先施行局部麻醉減輕排齦線操作時病患的不適感。再者，在使用排齦線排齦後，約會造成平均0.1mm牙齦退縮(Marginal recession)。 The gingival retraction procedure is generally used in dental clinics to temporarily push the patient's gingival sulcus horizontally and expand it to perform an impression operation. Gingival retraction cords are commonly used in the traditional way, which uses mechanical force to squeeze the retraction cord into the gingival sulcus to expand the gingival sulcus horizontally. However, the operation of the gingival cord requires a high degree of skill to smoothly fill the gingival cord into the gingival sulcus, and it usually takes about 7-10 minutes to operate a single tooth. Therefore, the operation of the retraction cord is difficult and time-consuming. In addition, local anesthesia must be applied first to reduce the patient's discomfort during the operation of the retraction cord. Furthermore, after using the retraction cord to retreat, dating causes an average of 0.1mm gingival recession (Marginal recession).
為了減少上述使用排齦線排齦的問題，也愈來愈多非排齦線(Cordless)的技術被提出來。例如，運用化學-機械的方式排齦，透過添加化學藥劑，例如三氯化鋁作為收斂劑的排齦材料，填入牙齦 溝排齦，操作上相對上更為便利，且也可解決排齦線的不適感。然而，此類型的排齦材料仍需花費一定時間擴大牙齦，且需利用沖水方式移除，無法保持乾燥，而導致後續印模操作上的困難。再者，現行的排齦材料若沒清除乾淨，也容易殘留、沾黏在牙齒、牙齦上。 In order to reduce the above-mentioned problem of using retraction cords to retreat, more and more cordless technologies have been proposed. For example, using a chemical-mechanical method to evacuate the gums, filling the gums by adding chemicals such as aluminum trichloride as an astringent evacuation material Groove retraction is relatively more convenient in operation, and can also solve the discomfort of the retraction line. However, this type of gingival retraction material still takes a certain amount of time to expand the gums, and needs to be removed by flushing, and cannot be kept dry, resulting in difficulties in subsequent impression operations. Furthermore, if the current gingival retraction material is not cleaned, it is easy to remain and stick to the teeth and gums.
因此，有需要提供一種新改良的排齦材料。 Therefore, there is a need to provide a new and improved gingival retraction material.
有鑑於此，本發明之一目的在於提供一種光固化排齦材料，可利用UV光照射，將此排齦材料由膏狀形態轉變成固體形態，再將之移除。由於，本發明之排齦材料可利用UV光照射的方式，迅速固化，可節省排齦程序的時間，且固化後的排齦材料可直接利用夾取方式移除，而不會造成殘留，而不需如習知方式沖水的方式移除，故本發明之光固化排齦材料可保持例如牙齦溝的乾燥。本發明實施例之光固化排齦材料可保持乾燥，也有利於後續之印模操作時可得到完整的修磨邊緣複製模型，而可確保及提高假牙膺復物的製作精度。 In view of this, one object of the present invention is to provide a light-curable gingival retraction material, which can be irradiated with UV light to convert the gingival retraction material from a paste-like form to a solid form, and then remove it. Because the gingival retraction material of the present invention can be rapidly cured by UV light irradiation, it can save the time of the gingival retraction procedure, and the cured gingival retraction material can be directly removed by clamping without causing residue, and It does not need to be removed by flushing in a conventional manner, so the light-curable gingival retraction material of the present invention can keep, for example, the gingival sulcus dry.
