Oral tissue regeneration involves the orchestration of known physiologic wound healing processes to synthesize single or composite tissues with functional, anatomical interfaces. Fundamental to oral tissue regeneration are the four main stages of wound healing: hemostasis, inflammation, proliferation, and remodeling. The oral cavity presents distinct challenges for regeneration due to its highly dynamic environment characterized by mechanical, microbiological, immunological, cellular, and biochemical factors that regulate cell-matrix interactions. The incorporation of natural or synthetic matrices and biologic agents introduces additional considerations in regenerative therapy. The intrinsic capacity for regeneration in oral tissues is dictated by the tissue type and the defect characteristics. Accordingly, defect classification systems aid in treatment planning, guiding the selection of clinical techniques and regenerative biomaterials. This review outlines the fundamental biological principles required to predictably regenerate alveolar bone, gingiva, and the periodontium. Further, emerging technologies poised to advance personalized therapy will be explored, including customized, bioprinted scaffolds, immunoengineering strategies, and organ-on-chip platforms for disease modeling and therapeutic development.
