The international standardization of dental magnetic attachments has been continued for over six years since gDevelopment and standardization of the dental magnetic attachment" supported by the NEDO grant was started in 2005. After NWIP (New Work Item Proposal) was presented in ISO/ TC 106/ SC2 in 2007 (Berlin meeting), a Japanese draft established by gThe Magnetic attachment standardization committee (the ISO Corresponding Committee in JSMAD)h was approved as WD 13017 (Working draft) in 2008 (ISO/ TC 106 Goteborg meeting). WD 13017 was revised to DIS 13017 (Draft of International Standard) in 2011 after CD 13017 (Committee Draft) in ISO/ TC 106 Rio de Janeiro meeting in 2010. Members of the Magnetic Attachment Standardization Committee are looking forward to a voting result of FDIS (Final Draft of International standard) in this year. If FDIS 13017 is carried in the voting, ISO 13017 (ISO standard of gDentistry-Magnetic attachmentsh) will come into the world in this year. In preparation for ISO/ TC 106 Paris meeting in 2012, the members make a challenge to a new standardization of measurement methods and jigs for the retentive force in magnetic attachments, now. The membersf activity already allows obtaining a souped-up jig for measuring retentive force.
