Prosthodontic management of Knife-Edge edentulous ridge using an innovative ASKER impression technique

The knife-edge edentulous residual alveolar ridge, commonly referred to as the knife-edge ridge, arises primarily from lateral resorption. This is characterized by rapid bone loss in both the buccal and lingual regions of the alveolar ridge. The mandibular edentulous ridge, especially in the anterior mandibular region, is frequently affected. Various factors contribute to its development, highlighting the multifactorial nature of residual ridge resorption. Managing knife-edge ridges presents challenges for prosthodontists. Conventional impression techniques may yield unstable or unsatisfactory dentures. To address these challenges, numerous impression materials and techniques have been proposed in scientific literature. The present case report introduces an innovative ASKER (Arpit Sikri Knife-Edge Ridge) impression technique-a copyrighted technique (ROC Number - L-139068/2023) designed to offer a straightforward and effective solution for managing the intricate knife-edge ridge in the mandibular arch. This technique involves integrating a customized commercially available prefabricated metal mesh into a custom tray made of light-cured acrylic resin. Alternatively, a single-step impression technique can be employed, using polyvinyl siloxane as the preferred impression material.
