Fusion Analyser: a novel measurement method and software tool for dental model analysis in orthodontics

Abstract Accurate analysis of dental models is crucial for diagnosing and treating malocclusion successfully. Traditional measurement techniques, however, often fail to accurately measure teeth in crowded conditions. In this study, we introduce Fusion Analyser (FA), an innovative software tool capable of calculating key dental indicators, thereby advancing the scope of digital dental model analysis. Our unique FA framework employs segmentation discs on teeth to enhance the accuracy of the anterior Bolton’s ratio, outperforming the widely-used 3Shape software when dealing with crowded teeth. The FA framework exhibits performance commensurate with the established gold standard, as evidenced by high scores across a range of evaluation metrics, thereby validating its accuracy, stability, and efficiency. The potential of the FA framework as an auxiliary tool for dentists, particularly in diagnosing and strategising treatment plans for malocclusion, is underscored.
