The double-cord packing technique is effective and safe for impression taking as long as the following steps are taken: Whenever possible, finish lines should be placed supragingivally. The gingival tissues should always be in good periodontal health. Two knitted cords of different sizes soaked in aluminum chloride solution are used. The first cord should be left in place while making the impression. Retraction cords should never be forced into the sulcus. Always remove both cords before dismissing the patient.
只要采取以下步骤，双绳填塞技术在取印模时就是有效且安全的：只要有可能，龈缘线应置于龈上。牙龈组织应始终保持良好的牙周健康状态。使用两根浸泡在氯化铝溶液中的不同尺寸的编织绳。在制取印模时第一根绳应留在原位。不应将缩龈绳强行塞入龈沟。在让患者离开之前，务必取出两根绳。
