Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of the study is to evaluate the effectiveness of clear aligners on the symptoms and signs reported by bruxism patients.

The aim of the investigators is to evaluate the effect of treatment on the masticatory muscles and the changes related to the tropism of the masseter muscles using Bruxoff ® device, before and after the beginning of the therapy. Bruxoff ® is a holter that assesses the contractions of the masseter muscles and the heart during sleep.

The plan is to compare treatment with clear aligners for bruxism and non-bruxism patients.

The results will allow the investigators to evaluate the progress of clear aligner therapy in bruxism patients and compare them with those of non-bruxism patients.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

bruxism patients assessed with Bruxoff ®

Subjects classified as bruxists based on the diagnostic criteria for sleep bruxism described by the American Academy of Sleeping Medicine, i.e. if they have at least one of the following two points:

1. The subject reports or is aware of noises of grinding or clamping during sleep.
2. One or more of the following signs are present:

* Abnormal wear of teeth;
* Discomfort, fatigue or pain in the muscles of the face;
* Hypertrophy of muscles during voluntary clamping;
* Any abnormalities in the mandibular muscle activity cannot be expressed by other sleep disorders, medical, neurological, drug use or substance abuse;
* Bruxoff ® cut-off more than 4.

Group Type ACTIVE_COMPARATOR

Bruxoff ®

Intervention Type DEVICE

Bruxoff ® is a holter that measures the masseter muscle contraction and heart rate.

non-bruxism patients assessed with Bruxoff ®

Subjects with good health, with no evidence of bruxism symptoms or signs. Bruxoff ® cut-off equal or less than 4.

Group Type ACTIVE_COMPARATOR

Bruxoff ®

Intervention Type DEVICE

Bruxoff ® is a holter that measures the masseter muscle contraction and heart rate.
