Abstract

The elderly population is increasing at a far more rapid rate in Japan than in Europe and North America. In fact, one Japanese in four will be over the age of 65 by 2020.<BR>At present, many elderly patients have multiple dental defects, even though the 8020 movement has been proposed. It is extremely important for us to provide high-quality medical care. Many teeth can now be preserved through progress in appliances, materials, and technology.<BR>We studied the characteristics of elderly patients and designed dentures with a double structure metal framework, with both the mechanical strength and durabilith. We also developed abutments using a coping telescope system.<BR>1. Overdentures for eldely patients should be designed in accordance with the principles for complete dentures.<BR>2. The denture border should cover the gingivolabial margin of the retainer, without notches at the denture border, and extend to gingivobuccal so far as possible.<BR>3. The, mucosal surface of the denture base should be of the total resin type.<BR>4. Metal base dentures with a double structure are able to withstand long-term use, and so are preferred for permanent dentures.<BR>5. Overdenture retainers should use a coping telescope system.
