Background: Bruxism is a condition that results from hyperactivity in the central nervous system, and factors such as stress or other anxious conditions increase the frequency of episodes. When bruxism occurs at a young age, tooth wear can occur. The extent of wear can lead to the need for restorative dentistry and prosthetic treatments to restore the morphological and functional integrity of the teeth, with high costs associated with such treatments.
Case report: A healthy 15-year-old boy presented to the orthodontist observation. His incisal ridges appeared thin, without mamelons, and with increased translucency. For treatment, the authors used only the Functional Plane of Monaco (FPM), a device which he had to wear 16 hours during the day.
Conclusion: The orthodontist successfully treated an orthopaedic/orthodontic case with the FPM device.
