<scp> BaSi <sub>2</sub> </scp> O <sub>2</sub> N <sub>2</sub> :Eu <sup>2+</sup> / <scp>PMMA</scp> Mechanoluminescent Composite Material for Occlusal Check in Occlusal Splint‐Dentures
Our work developed a BaSi<sub>2</sub>O<sub>2</sub>N<sub>2</sub>:Eu<sup>2+</sup>/PMMA mechanoluminescent composite for visualizing occlusal contact in occlusal splint-dentures. BaSi<sub>2</sub>O<sub>2</sub>N<sub>2</sub>:Eu<sup>2+</sup> (BSONE) was synthesized by a high-temperature solid-state method and incorporated into PMMA at different mass ratios (PB<sub>X</sub> refers to PMMA composites containing x wt% BSONE). Among the composites, PB<sub>4</sub> (4 wt%) exhibited the best overall performance. It showed the highest flexural and compressive strengths and the lowest wear rate. PB<sub>4</sub> also maintained stable mechanoluminescent intensity under varying temperatures, pH conditions, and repeated mechanical loading, and demonstrated good cytocompatibility. When applied to an occlusal splint-denture, PB<sub>4</sub> produced clear luminescent contact points that corresponded well with T-scan and occlusal paper results. These findings indicate that PB<sub>4</sub>-based occlusal splint-dentures offer a promising approach for visualizing and monitoring occlusal contact during clinical treatment.
