The importance of dento-maxillary prostheses has been emphasized, and new technology has been introduced with each revision of the insurance system. Therefore, to consider future insurance revisions, this study aimed to clarify how introduced technology has affected the actual state of insurance medical care for maxillofacial prostheses.
Based on the results of the survey by social medical practice （Ministry of Health, Labour and Welfare） from 2011 to 2020, the changes in the number of dento-maxillary prostheses and PAPs were tabulated, and the relevance to the contents of the insurance revision was considered.
Dento-maxillary prostheses decreased sharply in 2013, but increased from 2014 and remained flat after 2015 （about 300 cases/month）. However, the number decreased in 2020. PAP increased gradually from the time of introduction in 2014 to 2017, and has not changed much since then （about 100 cases/month）.
With the introduction of new insured technology, dento-maxillary prostheses have been enhanced and have also increased quantitatively to some extent, but there are still many unclear points in the actual situation. It is also suggested that dento-maxillary prostheses may not have been adequately delivered to patients in need.
