One of the most perplexing and tricky aspects of complete denture prosthodontics is the selection of appropriate maxillary anterior denture teeth size chiefly when no pre-extraction records are available. Despite the use of interalar distance, interpupillary distance, and distance between the medialis angles of the eyes is considered a reliable guide for determining the size of the maxillary anterior teeth to some extent, dental literatures indicate that there is no crucial method recommended. This study introduces a new methodology (3asal Methodology) and tool for determining the maxillary anterior teeth mesiodistal width based on certain stable guides that were derived from dentate casts with angle class I arch relationship and normal teeth alignment. These guides include basically the midline and the inter-canine line (a line joining the canine cusp and tips).
