Comments on
The Evidence
Subjects showing symptoms of TMD were selected for the RCT after being given a clinical examination and having their subjective symptoms recorded.
Applicability While both the NTI and full coverage appliances show to both be effective therapy for relieving the symptoms of TMD, the NTI is less effective, and puts the subject at risk of having occlusal changes, tooth mobility, and has a chance of being ingested or aspirated due to its small size.
