Various dental implant studies have been conducted because the biological and mechanical properties of implants can differ owing to the diversity of surf ace treatments, alloys, and macrodesigns. Previously, root analog implants were made using an impression of the extraction socket or extracted tooth. Recently, several studies have been conducted on implant manufacturing and application methods including computer-aided manufacturing, 3D printing, and digital technologies. In clinical applications, the mechanical and biological safety of root analog implants must be ensured; therefore, an appropriate evaluation method is required. The purpose of this narrative review is to describe the evaluation methods focusing on the mechanical strength, biological safety, and stability of root analog implants.
