Flabby ridge remained a challenge in dental clinical practice to obtain an accurate impression for edentulous patients. During the traditional impression making process, the excessive and displaceable soft tissue are usually compressed. In this article, we presented an impression method by using a modified special stock tray, impression compound and polyvinyl siloxane impression materials.•the suitable stock tray was modified with holes about 5 mm diameter in the corresponding area to the crest of the flabby ridge.•the primary impression was made by position the modified tray with the softened compound impression on the edentulous ridge, avoiding the area of the flabby ridge.•the final accurate impression was obtained by using the light body polyvinyl siloxane impression material.
松软牙槽嵴在牙科学临床实践中仍然是一个难题，难以给无牙颌患者获取精确印模。在传统印模制取过程中，过多且可移位的软组织通常会被压缩。在本文中，我们介绍了一种使用改良特殊托盘、印模膏和聚硅氧烷印模材料的印模方法。•在与松软牙槽嵴嵴顶相对应的区域，用直径约5毫米的孔对合适的成品托盘进行改良。•将装有软化印模膏的改良托盘置于无牙颌牙槽嵴上，避开松软牙槽嵴区域制取初印模。•使用轻体聚硅氧烷印模材料制取最终精确印模。
