What is the longevity of removable prosthodontics?
9 Responses »
This rapid technology review of the longevity of removable dental prostheses focused on complete dentures and partial plastic or metal dentures. It included a small number of systematic reviews, which were of limited quality and based on a small number of small studies. While good 5 year survival rates were found, the quality of the evidence means that the findings should be interpreted cautiously.
