Purpose: An abundance of novel materials has been added to the dental prosthodontics market. Among these materials, a new category – the “hybrid ceramic” seems to have gained researcher’s interest. It is yet unclear which biomaterials should be labelled as “hybrid ceramics”. This bibliometric and narrative review aims to find which biomaterials are referred to as “hybrid ceramic” and describe their principal properties, when available. Materials and methods: Two reviewers executed a literature search up to the 15th June 2024 in three electronic databases PubMED, Web of Science and Scopus. All commercial names of biomaterials labelled as "hybrid ceramic" were retrieved, if pertinent to the dental prosthesis. Articles referring to hybrid ceramic abutments were excluded. Results: 771 studies mentioning a “hybrid ceramic” have been identified and 226 have been selected for this bibliometric study. 25 biomaterials have been identified labelled a “hybrid ceramics,” including 4 experimental biomaterials, 2 indirect lutable composites, 3 glass ceramics, 2 printable permanent crown resins and 14 resin based CAD/CAM blocks. Their mechanical, optical and biological properties have been described, when available. Conclusions. Hybrid ceramics are popular in the research field yet are often mislabelled. A new, detailed classification is needed.
