Mishmash Impression Technique for Managing Maxillary Anterior Fibrous Ridge

Introduction: Flabby or fibrous ridge is one of the consequences of long term wearing of complete dentures. It can develop where hyperplasic soft tissue replaces the alveolar bone and is a common finding, particularly in the upper anterior region of long term denture wearers. Forces exerted during impression making can result in distortion of the mobile tissue unless managed appropriately; such flabby ridges adversely affect support, retention and stability of complete dentures. Many impression techniques have been developed to help overcome this problem. While these vary in the method applied, they are similar in their complexity, are often quite time-consuming to perform and rely on materials not commonly used in contemporary general dental practice. The purpose of this article is to describe an impression technique for flabby ridges usingrubber base impression materials, routinely available in general dental practice.
