Accurate impressions are essential in orthodontics for effective diagnosis, treatment planning, and appliance fabrication. While standard stock trays are commonly used, they may fail to provide sufficient coverage in cases with severe proclination of upper anterior, excessive spacing, or larger upper arches, especially when extending to the second molar. In such situations, custom impression trays are critical for improving accuracy and fit. They ensure complete coverage of posterior teeth, control the thickness of the impression material, and prevent soft tissue impingement, thereby enhancing patient comfort. Additionally, custom trays can incorporate advanced features like the Hyrax Expander to improve fit, retention, and stability. This approach minimizes the need for re-impressions, saving chair-side time and improving the overall efficiency of orthodontic procedures. By utilizing custom trays, orthodontists can achieve more precise impressions, leading to better clinical outcomes and increased patient satisfaction.
