ABSTRACT

Aim of the study This systematic review aimed to centralize the information regarding the effect of the orthodontic treatment with clear aligners (CAT) on the masticatory muscles activity, functional or parafunctional, by objective recording means of surface electromyography (sEMG). Materials and methods : An electronic search was performed until June 2024 using the following search strategy :(((orthodontic OR clear OR removable) AND (aligner*)) OR Invisalign) AND (Bruxism OR (parafunctional masticatory forces) OR (masticatory muscle activity) OR clenching) AND (EMG OR Electromyography). Time restrictions for the search were established between 2000-2024.

Results 640 studies were computed. Using the PRISMA method, 38 duplicates were found and removed to obtain 602 studies to be screened by title and abstract.  9 studies were eligible to be reviewed. Conclusions CAT does not influence muscle activity. Most of the data available is about the response of the masseter muscle but there is no clear evidence that this is the most affected muscle by bruxism.
