Abstract

Facial paralysis presents significant functional and aesthetic challenges, particularly through lip posture deficits such as drooping and drooling, often inadequately addressed by traditional surgical or drug-based interventions, especially in debilitated patients. This study explores the application of engineered polymer composites in a novel, non-surgical lip posture corrector designed to statically suspend and correct lip position without requiring surgical or dental support. The device utilizes a precisely formulated blend of polymethylmethacrylate (PMMA) acrylic resin and a copolymer of sodium acrylate and acrylamide in a 1:2 weight ratio, with the copolymer synthesized at a 10:90 sodium acrylate-to-acrylamide ratio. This specific formulation of engineered polymer composites is optimized to enhance mechanical stability while maintaining essential flexibility and biocompatibility for intraoral use. The research investigates the synthesis, mechanical properties, biocompatibility, and toxicological aspects of these engineered polymer composites, evaluating their efficacy in achieving lip symmetry and ensuring patient safety. Experimental results demonstrate the composite’s superior performance compared to standalone PMMA, exhibiting improved mechanical properties and reduced cytotoxicity. By leveraging the principles of material science and medical device engineering, this study provides valuable insights into the design and application of engineered polymer composites for non-invasive therapeutic applications. Furthermore, the findings highlight the potential for future advancements in tailored composite materials for facial rehabilitation, offering a promising alternative to traditional treatment modalities and bridging the gap between material science and clinical applications in the management of facial paralysis-induced lip dysfunction. This study aims to bridge the gap between material science and clinical applications, paving the way for innovative solutions in the management of facial paralysis-induced lip dysfunction.

Keywords: Polymer chemistry, lip posture corrector, PMMA, sodium acrylate-acrylamide copolymer, facial paralysis, biocompatibility, polymer blends, medical composites.
