Abstract: A method for warning of an instrument break risk during an endodontic treatment. The method includes the following steps: acquiring the shape of a root canal to be treated; identifying a risk zone, on the basis of complexities in the shape of the canal, such as bends or bifurcations in the canal; in real-time, acquiring a working depth of the instrument; determining the position of the instrument within the canal, and issuing a warning when the instrument reaches the risk zone.

Abstract: A root canal treatment device relates to the technical field of dental treatment instruments. The root canal treatment device comprises a contra-angle hand-piece (10) and a root canal file (20) detachably connected to the contra-angle hand-piece (10), and further comprises a drive module (30) in transmission connection with the root canal file (20), the drive module (30) comprises a rotation driver (31) and a vibration generator (32), wherein the rotation driver (31) is configured to drive the root canal file (20) to rotate axially, so as to mechanically cut and ream the root canal, thus shaping the root canal, and the vibration generator (32) is configured to drive the root canal file (20) to vibrate radially. Vibration of the root canal file (20) at a specific frequency can sufficiently activate the activity of the drug material filled in the root canal, especially in the process of filling the drug material into the root canal, the vibration provided by the vibration generator (32) and the rotation of the root canal file (20) that are carried out simultaneously can efficiently discharge the air bubbles in the drug material filled in the root canal, so that the drug material can be tightly filled into the root canal, thereby providing a better environment for subsequent root canal treatment, improving the effect of root canal treatment, and relieving the patients' pain.

Abstract: A robotic system includes a base, a grounding arm, a working arm, and one or more sensors. The grounding arm extends from the base and is configured to be coupled to a fixed structure within the mouth of the patient for establishing an origin for the robotic system. The working arm extends from the base and is configured to be coupled with one or more tools for use during an installation of a dental implant in the mouth. The one or more sensors are for monitoring positions of the grounding arm and/or the working arm and to generate positional data that is used to create a post-operative virtual three-dimensional model of at least a portion of the mouth of the patient.
