Gingival displacement is critical for obtaining accurate impressions for the fabrication of fixed restorations, especially when the finish line is at or just within the gingival sulcus. Displacement of the gingival tissue is also important when dealing with the restoration of cervical lesions due to their proximity to the periodontal tissue. The methods of gingival tissue displacement can be broadly classified as nonsurgical and surgical techniques, with nonsurgical being the more commonly practiced method. Dentists must alter their armamentarium and gingival displacement techniques to meet specific demands and obtain predictable results. Hence, the purpose of this article is to describe the different means by which nonsurgical gingival displacement can be achieved effectively under a variety of clinical situations.
牙龈移位对于获取用于制作固定修复体的精确印模至关重要，尤其是当肩台位于龈沟内或刚好在龈沟内时。在处理颈部病变的修复时，由于其靠近牙周组织，牙龈组织的移位也很重要。牙龈组织移位的方法可大致分为非手术和手术技术，其中非手术方法是更常用的方法。牙医必须改变他们的器械和牙龈移位技术，以满足特定需求并获得可预测的结果。因此，本文的目的是描述在各种临床情况下有效实现非手术牙龈移位的不同方法。
