Abstract: The Clinical Guideline of Using Gold Alloy for the Restoration of Tooth Defect (hereinafter referred to as the Guidelines), spearheaded by the Chinese Stomatological Association, officially came into effect on January 1, 2021. Underpinned by the principles of evidence-based medicine, the Guidelines systematically summarize the material properties, classifications, indications, and standardized clinical protocols of gold alloy restorations. The primary objective is to standardize and promote the application of this classic restorative technique in the treatment of tooth defects.This article aims to provide a profound interpretation of the Guidelines core content. By integrating clinical practice, it elucidates the technical essentials of key procedures, the critical factors in selecting indications, and the importance of postoperative maintenance. These insights are intended to assist dental clinicians in better understanding and implementing the Guidelines, ultimately enhancing the clinical efficacy and long-term survival rate of gold alloy restorations.
