Abstract：
The single-cone technique, also known as the hydraulic condensation technique, is widely employed in endodontics. However, the aforementioned method is presented with certain limitations; specifically concerning the coronal seal and the adaptation of the coronal third of a master gutta-percha (GP) with a round cross-section to the coronal dentinal walls of root canals with semi-round or oval cross-sections. Through two case reports, the current article introduces the coronal vertical condensation (CVC) technique; aiming to enhance GP adaptation to canal walls in similar scenarios. In fact, the coronal vertical condensation technique amalgamates the different aspects of warm vertical condensation and single-cone techniques. In CVC, following the placement of the master GP cone, an electrical heat carrier is inserted immediately a few millimeters apical from the canal orifice to remove the coronal portion of the master GP cone. Subsequently, a hand plugger is used to condense GP in the vertical dimension, and the coronal space is backfilled using melted GP. The implementation of CVC technique has demonstrated an improved coronal adaptation of GP with canal walls. The stated technique seems beneficial; especially in the obturation of severely curved canals or root canals with a final preparation shape of variable taper.
摘要：
单锥技术，也称为液压冷凝技术，广泛应用于牙髓。然而,上述方法具有一定的局限性；特别是关于冠状密封和具有圆形横截面的主牙胶（GP）的冠状三分之一与具有半圆形或椭圆形横截面的根管的冠状牙质壁的适应。通过两个病例报告,本文介绍了冠状垂直冷凝（CVC）技术；旨在在类似情况下增强GP对运河壁的适应。事实上,冠状垂直冷凝技术将温暖的垂直冷凝技术和单锥形技术的不同方面合并在一起。在CVC中，在放置主GP锥之后，将电热载体从管口的顶端立即插入几毫米，以去除主GP锥体的冠状部分。随后，手动插件用于在垂直维度上压缩GP，日冕空间用熔化的GP回填。CVC技术的实施证明了GP与管壁的冠状适应性的改善。所述技术似乎是有益的；尤其是在严重弯曲的运河或根管的闭塞中，最终准备形状为可变锥度。
