The invention relates to the field of dental department and particularly relates to an auto-implanting dental robot. The oral implantology robot includes: a modularized structure, an implanting navigation system, a tracing and positioning system, a mechanical arm system, an implanting driving system, and a control system. The oral implantology robot can integrate and analyzes information from allunits, including: CT information, implantology scheme, oral cavity information and mechanical arm information, thereby sending a command to control a mechanical arm to achieve automatic implantology.The modularized structure includes a trolley structure and a support structure connected thereto, wherein the support structure is connected to all the functional units, including the mechanical arm,a tracer and a monitor. The implanting navigation system can achieve pre-operation implanting scheme design, intraoperative registration, information integration and analysis, command sending and feedback receiving. Implantology drill point registration tools are individually designed on the basis of implantology tools in different brands, thus solving a problem of low accuracy of manual registration. Due to the modularized structure, dental implantology operation situations are fully considered, so that auto-implanting operation has better operability.
