Abstract
Objective: This study aimed to assess the effects of aligners on masseter muscle activity by using an electromyographic device in the home environment.
Methods: The study was performed on healthy patients who required orthodontic treatment. Three different 24 h-EMG recording sessions were performed in different conditions: without aligners, with passive aligners, and with active aligners. The non-functional MMA work index (nfMMA-WI) and the non-functional MMA time index (nfMMA-TI) for both awake and sleep hours were assessed. ANOVA test was used to compare the average activity during the three recording conditions.
Results: On average, a total recording time of 204.7 ± 7.9 hours were provided for each patient. For most patients, ANOVA test showed an absence of significant differences between the recording sessions.
Conclusions: The impact of our results is not negligible: clinicians can find remarkable support to the hypothesis that the use of aligners affects the MMA only in a minority of subjects.
期刊介绍:
CRANIO: The Journal of Craniomandibular & Sleep Practice is the oldest and largest journal in the world devoted to temporomandibular disorders, and now also includes articles on all aspects of sleep medicine. The Journal is multidisciplinary in its scope, with editorial board members from all areas of medicine and dentistry, including general dentists, oral surgeons, orthopaedists, radiologists, chiropractors, professors and behavioural scientists, physical therapists, acupuncturists, osteopathic and ear, nose and throat physicians.
CRANIO publishes commendable works from outstanding researchers and clinicians in their respective fields. The multidisciplinary format allows individuals practicing with a TMD emphasis to stay abreast of related disciplines, as each issue presents multiple topics from overlapping areas of interest.
CRANIO''s current readership (thousands) is comprised primarily of dentists; however, many physicians, physical therapists, chiropractors, osteopathic physicians and other related specialists subscribe and contribute to the Journal.
