Abstract
The biocompatibility of dental materials is a critical factor influencing the outcomes of dental restorative treatments, and with the advancement of dental medicine, the requirements for these materials have become increasingly stringent. This study aims to investigate the biocompatibility and clinical application value of novel dental materials by integrating in vitro cellular experiments with in vivo animal studies to systematically evaluate the biological responses of various new dental materials under different conditions. Representative materials such as nanocomposite resins and zirconia ceramics were selected for evaluation. Cell viability was assessed using the MTT assay, cell morphology was observed via scanning electron microscopy, and levels of inflammatory cytokines were measured using ELISA. Additionally, animal implantation experiments were conducted to evaluate tissue compatibility. The results demonstrated that nanocomposite resins exhibited excellent cytocompatibility with cell survival rates exceeding 90%, and only mild inflammatory reactions. Zirconia ceramics showed superior osseointegration capabilities, forming a stable bone integration interface at the implant site. Innovatively, this study introduced a multidimensional comprehensive evaluation system, focusing not only on traditional cytotoxicity indicators but also on long-term interactions between materials and host tissues, thereby providing a scientific basis for clinical selection. The findings indicate that dental materials with good biocompatibility can significantly enhance restoration success rates and reduce complication incidences, offering new directions for the field of dental restoration and promoting the application of personalized medical concepts.
