The demand of high-quality medical services continues to increase with the nation's growing prosperity and the continuous extension of average life expectancy. Facing these heightened medical demands, particularly the challenges of oral frailty and multimorbidity in an aging society, the traditional diagnostic and therapeutic system for prosthodontics increasingly reveals limitations, including insufficient information coverage, obscuring the underlying etio-logy, the neglect of individual psychological needs, and a lack of holistic consideration for multimorbidity. This consensus proposes the \"Four-Level and Dual-Axis\" comprehensive diagnostic and therapeutic system for prosthetic rehabilitation of oral diseases to address these bottlenecks in disciplinary development. This system classifies the diagnostic scope from micro to macro into four functional levels of \"tooth-pulp\", \"dentition-occlusion\", \"occlusion-temporomandibular joint\", and \"maxillofacial-systemic\" emphasizing the pathological cascade reactions between levels and a bidirectional diagnostic logic. Simultaneously, it introduces a subjective-objective dual-axis assessment model comprising \"individual psychology and prosthetic needs (axis A)\" and \"etiology and patho-anatomical diagnosis (axis B),\" achieving an integration of medical rationality and humanistic care.
