Predictability of orthodontic tooth movement with aligners: effect of treatment design.

Backgrounds: The present study was designed to define: (1) which are the less predictable OTM with Invisalign aligners when the treatment plan is designed by expert operators, (2) if the presence and shape of attachments influence the predictability of OTM and (3) if patients' demographics influence OTM predictability. The sample comprises 79 prospectively recruited patients (mean age 30.8 years; SD 12.

Chronic pain and weather conditions in patients suffering from temporomandibular disorders: a pilot study.

Nevertheless, scientific evidence supporting this relationship is scarce. The aim of this study was to assess a potential relationship between pain intensity and meteorological factors, through a newly developed, portable device, in patients affected by chronic masticatory muscle pain.
