Dental anatomy education for dental technology students should be developed in alignment with digital dental laboratory practices. We hypothesized that a virtually assisted sketching-based dental anatomy teaching module could improve students' acquisition of skills essential for digital restoration design. The second-year dental technology curriculum included a novel virtual technology-assisted sketching-based module for dental anatomy education. Pre- and post-course assessments evaluated students' skill sets and knowledge bases. Computer-aided design (CAD) scores were analyzed after one year to assess how the skills students developed through this module impacted their subsequent CAD performance. Participants who undertook the dental sketching-based teaching module demonstrated significantly improved theoretical knowledge of dental anatomy, dental aesthetic perception, and spatial reasoning skills. A partial least squares structural equation model indicated that the positive effects of this module on subsequent CAD performance were indirectly mediated by dental aesthetic perception, spatial reasoning, and practice time. A virtually assisted sketching-based dental anatomy teaching module significantly improved students' acquisition of skills and knowledge and positively mediated dental technology students' CAD performance.

The realization of ecological product's value is significant for China to build ecological civilization and practice the Two Mountains strategy. The study aims to explore the logic and practical laws of ecological product value realization (EPVR). Based on resource orchestration theory (ROT), we extracted the logical process of EPVR, which includes three sub-processes: resource aggregation, ability fusion, and value focus. We then made an exploratory case analysis on the EPVR practices of Guangdong and Hainan, two provinces of China, and derived the practical processes of EPVR. The study shows that first, the differences in resource conditions give the provinces different performances in EPVR practices; second, the abilities of input, operation, and organization generating in ability fusion phase help provinces break through resource constraints; and finally, the development of ecological economy through focusing ecological resources and assets on regional ecological industries with comparative competitive advantages is an important way to transform products' ecological attribute into value attribute. The interrelated and dependent three phases dominate the operation and development logic of EPVR. The results are conducive to a deeper understanding of EPVR mechanism and provide implications for provincial governments to optimize their programs and policies of ecological civilization construction.
