Abstract: Bruxism is a condition in which a person involuntarily grinds, clenches, or gnashes their teeth, either during sleep(sleep bruxism) or while awake(awake bruxism). In this project we focuses on designing and developing biodegradable and low-cost mouth clip using poly lactic acid (PLA) through 3D printing, coated with a starch-glycerin biopolymer to enhance surface comfort, safety, and bio compatibility. Conventional oral biomedical devices are often expensive, non-biodegradable, and unsuitable for widespread use in rural or resource-limited settings. PLA, being a renewable thermoplastic, provides an affordable and eco-friendly base material, while starch-glycerin coating improves smoothness, durability, and intraoral compatibility. The process involves creating a patient-specific design using computer-aided design (CAD), fabricating the clip through fused deposition modeling (FDM), and applying a starch glycerin gel solution by dip-coating or brush-coating, followed by drying to form a thin protective layer. This combination provides a sustainable, customizable, and economical solution for oral healthcare. The coated PLA mouth clip demonstrates potential applications in oral rehabilitation, tongue positioning therapy, stabilization of feeding tubes, and intraoral biomedical sensor support. This project highlights the benefits of combining 3D printing technology with natural biopolymer coatings, offering a safe, eco-friendly, and accessible alternative to conventional oral clips. The invention supports the transition toward sustainable biomedical devices and opens avenues for future development of low-cost, patient specific healthcare tools.
