BASEL, Switzerland, July 19 (World Daily Times) — For someone facing a dental crown, the appeal is easy to see: fewer visits, less time in the chair, and a faster finish. Researchers at the University of Basel say a miniature robot called MIR could one day help make that possible. But the device is still a prototype, and the sources provided do not show that it has been tested in patients.
What is MIR?
MIR stands for Miniature Intraoral Robot. The University of Basel team says the prototype is about the size of a wine cork, measuring 43 by 26 by 28 millimeters. Dr. Yukiko Tomooka, the paper’s first author, said the robot “is designed to be small enough to fit comfortably into an open mouth.”
The robot is meant to be attached to a custom dental splint made from a patient’s scan. According to the University of Basel researchers, the motors and control systems stay outside the mouth and connect to the robot through flexible drive shafts, cables and tubes.
How would it work in a crown appointment?
The researchers say the goal is to streamline the process of preparing a tooth for a crown. In their proposed workflow, a dentist would scan the tooth during an initial visit, plan the crown preparation digitally and order the crown right away. That could, in theory, reduce the need for a second appointment.
That does not mean the robot is ready for use in a dental office now. The sources provided describe MIR as an early-stage prototype, not a clinical tool.
How accurate was it in testing?
In laboratory tests, the University of Basel team says MIR worked on synthetic resin tooth models and on a ceramic material with hardness similar to tooth enamel. The reported positional error was less than 0.2 millimeters.
The robot also kept drilling forces below 5 newtons in testing. One report described that force as roughly equal to the pull of a half-liter bottle of water.
Even so, the current version does not yet have sensors to directly measure or correct its position, according to the researchers.
What comes next?
Professor Georg Rauter, who leads the research group, said the next step is to add sensors and a camera so MIR can monitor its position and treatment progress without getting larger. He also said, “Even after a power outage, MIR would know where it is and where it needs to continue based on the sensor data.”
The project page for MIR lists collaborators including BIROMED-Lab, the Clinic of Reconstructive Dentistry at the University of Zurich, Camlog Biotechnologies and the University of Bern’s ARTORG Center. It also says the project is sponsored by Innosuisse, Switzerland’s innovation agency.
Should patients trust it now?
Not yet. Based on the supplied sources, MIR has not been shown in patient trials, and no source says it has regulatory clearance or is ready for routine dentistry. For now, it is best understood as a promising engineering project: a small robot that may one day help dentists work faster, but not one that changes care today.
