ABSTRACT:
The invented anti-contamination orthodontic device dispenser includes a container for housing orthodontic devices, an aperture in the container through with the devices are dispensed, and a guide structure which directs the devices to the aperture for dispensing. The dispenser is gravity and friction controlled so that when one device is dispensed, the next device is presented and ready for dispensing. The container and guide structure are constructed so that the devices are stacked on top of each other and touching because of gravity. Each device has a tooth on its upper surface and ridges on its lower surface. When a device is dispensed, its tooth contacts the ridges on the device immediately above it creating friction which positions the next device for dispensing. The invented dispenser is particularly effective for dispensing orthodontic O-rings mounted on a carrier or stick.
