Fibrous ridges on the edentulous maxillary arch are commonly found in combination syndrome or due to ill-fitting dentures. Often, these cases are managed conservatively using modified impression techniques to achieve better support and peripheral seal without displacing the movable tissue. Many impression techniques were proposed and justified with their respective ideologies, but some may complicate both the clinical and laboratory procedures. In this report, two simplified techniques are demonstrated to make an impression of the maxillary arch with fibrous ridges. Laboratory steps in custom tray fabrication are also emphasised for a successful and predictable impression.
无牙上颌弓的纤维嵴通常与联合综合征或不合适的义齿有关。通常,这些病例采用改良印模技术进行保守治疗,以在不移动可动组织的情况下获得更好的支持和周边密封。许多印模技术都有各自的理论依据,但有些技术可能会使临床和实验室操作复杂化。在本报告中,展示了两种简化技术来制取带纤维嵴的上颌弓印模。还强调了定制托盘制作中的实验室步骤,以获得成功和可预测的印模。
