A dental robot includes a platform and a suspension system. A suspension system supports the platform and automatically compensates for the weight of the platform as well as the robotic arms, end effectors, and tooth clamps attached thereto. The suspension system maintains the height of the platform above the base constant without an external force on the tooth clamp. The suspension system allows the position and orientation of the platform to change relative to the base in response to an external force on the tooth fixture greater than about 0.1 N, such as due to the subject's activity (change in position and / or orientation). Thus, the position and orientation of the platform remains fixed relative to the teeth of the subject in response to movement of the teeth.

The invention includes a group of devices allowing people to indicate when and where they experience pain or discomfort, and a system and method for using this information to improve clinical medical care.

The concave ridge may extend between the upper edge and the lower edge of the band and between the proximal and distal ends of the band.

One object of the present invention is to provide a tooth stabilization device that prevents patients from easily releasing their teeth from the device during dental surgery. To this end, the inventors have proposed a tooth stabilization block that includes internal channels opening onto the surface of the block that contacts the patient's teeth. These internal channels connect to an inlet through which a bite registration material, designed to harden and mold to the patient's teeth, can be injected. This makes it more difficult for the patient to release their teeth from the tooth stabilization block once the bite registration material has hardened and molded around the teeth.
