Abstract

Technical Review Guidelines of Medical Devices are standards to standardize and unify registration review of medical devices marketed in China. The writing quality of the guidelines affects not only the time for technical evaluation, but also the safety and effectiveness of approved products. Based on authors' practices of nearly 30 class II medical equipment technical guidelines written and 20-year experience in class II medical device evaluation, this study takes intraoral digital dental impressions as an example to put forward several key points of sections "summary" and "research data" in the guidelines, for researchers on class II medical equipment technical guidelines reference.
