Abstract


Intra-oral scanners sit at the crossroads of precision optics, demanding regulatory traceability and a rapidly growing digital-dentistry market. This paper demonstrates how integrating Lean production with Industry 4.0 technologies - an approach hereafter referred to as Lean 4 - simultaneously boosts plant performance and organizational capability inside a medium-volume scanner factory. A cloud-based digital twin was used to map the present value stream and to test alternative flow designs before implementation. The selected solution combined a manufacturing execution system driven by electronic Kanban, optical inspection supported by artificial intelligence, collaborative calibration robots, and real-time dashboards for overall equipment effectiveness, all aligned with the requirements of the International Organization for Standardization standard 13485. After six months, throughput time fell by twenty-nine percent, first-pass yield increased by twenty percent, calibration rework decreased by thirty-five percent, and required floor space shrank by eighteen percent. Equally important, cross-functional, data-centered teams replaced functional silos, reducing decision latency on the shop floor by thirty-seven percent and lifting employee engagement by twenty-two percent. The findings confirm that Lean 4.0 acts as a double lever, delivering waste elimination while generating the organizational agility demanded by fast-moving dental markets.
