AI Technical Summary
Existing zirconia all-ceramic crowns have pre-drilled holes that easily accumulate food debris, affecting oral hygiene and reducing the lifespan of the integrated bridge. Furthermore, the connection relies on friction, which can easily lead to separation.
It adopts an elastic rod connection structure, a groove and protrusion design, and a slider and groove cooperation. By bending and restoring the elastic rod and fine-tuning the slider, the number of connection points is increased, enabling hole-free installation and multi-point connection.
This prevents food residue buildup, enhances connection stability, improves wearing comfort, and extends the lifespan of the integrated bridge.
