AI Technical Summary
In current technology, measuring the crown width of a three-dimensional dental model relies on manual measurement by a professional dentist, which is inefficient, costly, and difficult to guarantee measurement accuracy, especially for malformed teeth.
By employing mesh projection and principal component analysis feature dimensionality reduction methods, the crown width is automatically measured by calculating the normal vector and scale line of the crown mesh. The use of normal vector features and principal component analysis eliminates the need for manual intervention.
It enables personalized crown width measurement without human intervention, improving measurement efficiency and accuracy, reducing measurement costs, and enhancing the universal applicability of the algorithm.
