A digital impression technique has revolutionized dental diagnostics and restorations by offering enhanced precision, faster workflow and improved patient comfort. However like any technological advancements it is not immune to challenges. Failures in digital impression techniques can arise due to various factors including operator error, equipment malfunction, inadequate scan data, etc. These failures can result in inadequate impression, poor fit of restoration, delay in treatment. This abstract explores the common causes of failure in digital impression techniques, including issues related to scanning protocols, patientrelated factors (such as motion or anatomy), and technical limitations of the equipment used. Furthermore, it emphasizes the importance of proper training, calibration, and troubleshooting to mitigate these issues and enhance the reliability of digital impressions. Understanding these failure points is crucial for dental professionals to optimize the use of digital technologies and ensure optimal patient outcomes.
