Managing Fibrous Maxillary Ridge: A Case Series of Impression Techniques

Abstract

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.
