Bionic Morphology of Dental Articulator for Teaching Based on Topological Theory

In order to better meet the needs of stomatology teaching demonstration, the paper conducts a research on the modified bionic design of the traditional dental articulator. Topology is introduced into the morphological bionic design for quantitative analysis. Starting from shape, the common point of topology and bionic design, to analyze the topological structure of \"human craniofacial bone\" based on the existing structure of dental articulator. This paper simply divides the complex topological relationships into five topological relationships (separation, adjacency, intersection, containment, and equality) based on the 9IM model, and set topological weight for these five representative topological relationships. Topological weight can be used to quantify the relationship between spatial entities and extract important features. The stability of topological properties in morphological cognition and extraction is used to better rationally restrict the bionic design process, finally establish a preliminary bionic morphological model.
