Robotic device for dental surgery

A robotic system for use during installation of a dental implant in a mouth of a patient, the robotic system comprising:

• a base;
• grounding arm extending from the base and being configured to be coupled to a fixed structure within the mouth of the patient for establishing an origin for the robotic system relative to the mouth of the patient;
• working arm extending from the base and being configured to be coupled with one or more tools for use during the installation of the dental implant, at least a portion of the working arm boing movable to install the dental implant in the mouth of the patient;
• and
• one or more sensors to monitor positions of the grounding arm and the working arm, the one or more sensors generating positional data that is used to create a virtual model of at least a portion of the mouth of the patient.

A method of creating a post-operative virtual model of at least a portion of a mouth of a patient, the mouth including a dental implant installed using a robotic system during a dental surgical procedure, the method comprising:

• attaching a rigid grounding member to a fixed position within the mouth of the patient;
• obtaining a pre-operative virtual model of the mouth of the patient with the rigid grounding member therein;
• coupling a grounding arm of the robotic system to the rigid grounding member in the mouth of the patient, thereby establishing an origin for the month of the patient;
• moving, as part of the dental surgical procedure, at least a portion of a working arm of the robotic system coupled to a dental-implant-driving tool to install the dental implant in the mouth of the patient;
• monitoring, during the dental surgical procedure, a position of the grounding arm and the working arm to generate positional data related to the location of the dental-implant-driving tool relative to the established origin;
• and
• creating the post-operative virtual model of the at east a portion of the mouth of the patient based on the obtained pre-operative virtual model and the generated positional data.
