Training device for dental students to practice mirror-inverted movements

The goal of this study was to explore whether the ability of precise mirror-inverted movements can be learned and improved with the device Mirroprep and whether practice success can be transferred to the clinical situation. Three groups of students at different levels of dental study and different achievement levels were asked to perform a drawing exercise with indirect vision using Mirroprep. Further, the group of most senior students were asked whether the motor skills learned with this device were helpful in clinical tooth preparations by use of the dental mirror. According to the test results, we were able to show that mirror-inverted motor functions can be learned and improved by practice and that it is also helpful for performing tooth preparations. Because of this, it is deemed reasonable for students to start practicing with the training device during their preclinical studies and to have their skills tested.
