Advances in Adhesive Materials for Oral and Maxillofacial Soft Tissue Diseases

Oral diseases represent a prevalent global health burden, profoundly affecting patients' quality of life. Given the involvement of oral mucosa and muscles in diverse physiological functions, coupled with clinical aesthetics considerations, repairing oral and maxillofacial soft tissue defects poses a formidable challenge. Wet-adhesive materials are regarded as promising oral repair materials due to their unique advantages in easily overcoming physical and biological barriers in the oral cavity. This review first introduces the intricate wet-state environment prevalent in the oral cavity, meticulously explaining the fundamental physical and chemical adhesion mechanisms that underpin adhesive materials. It then comprehensively summarizes the diverse types of adhesives utilized in stomatology, encompassing polysaccharide, protein, and synthetic polymer adhesive materials. The review further evaluates the latest research advancements in utilizing these materials to treat various oral and maxillofacial soft tissue diseases, including oral mucosal diseases, periodontitis, peri-implantitis, oral and maxillofacial skin defects, and maxillofacial tumors. Finally, it also highlights the promising future prospects and pivotal challenges related to stomatology application of multifunctional adhesive materials.
