Abstract: BACKGROUND: At present, the microorganisms associated with peri-implantitis are not completely clear. As a method of studying microbial diversity without culture, metagenomics is gradually applied to the study of oral microorganisms.
OBJECTIVE: To review the application of metagenomics in peri-implantitis.
METHODS: The first author searched PubMed, WILEY, Web of Science and CNKI databases using computer for relevant articles published from January 1998 to August 2020. The search terms were “metagenomics, high-throughput sequencing, peri-implantitis, next-generation sequencing” in English and Chinese, respectively. The articles related to metagenomics and peri-implantitis were reviewed. 
RESULTS AND CONCLUSION: Peri-implantitis may be caused by multi-bacterial infection, and its pathogenesis is still unclear. Metagenomics, as a method of identifying microorganisms without culture, extracts DNA from all samples in a specific environment, and then compares them with the established genomic library. All the genetic materials in the samples were analyzed, and the composition and community characteristics of microorganisms were studied. Culturomics is a method that uses a variety of culture conditions to culture bacteria. It uses matrix assisted laser desorption ionization time-of-flight mass spectrometry to identify microbical species. Although metagenomics and culturomics are different analysis methods, the aim is the same; that is, to detect as many microbial species as possible in a specific ecosystem. Metagenomics, combined with molecular analysis technology and culturomics used in the study of peri-implantitis, will accelerate the process of understanding peri-implantitis, and metagenomics will be improved with the understanding process of peri-implantitis.

Key words: implant, metagenomics, high-throughput sequencing, peri-implantitis, next generation sequencing, PCR and 16S rRNA, culturomics
