Impact of Orthodontic Treatment on the Temporomandibular Joints (TMJ) Assessed by Modjaw

Not Applicable

Recruiting

• Conditions: Temporomandibular Joint Disorders
• Interventions: Device: Review by Modjaw

• Registration Number: NCT05710952
• Lead Sponsor: University Hospital, Montpellier

Brief Summary

The aim of the study is to assess the correlation between orthodontic treatment and temporomandibular joint (TMJ). For that, an evaluation with a virtual articulator (Modjaw) is carried out before and after the treatment. The condylar course are compared. Furthermore, the eventual TMJ symptoms are also compared before and after.

Primary Outcome Measures

Name	Time	Method
Gap reduction between the interincisive point in mouth opening and the ordinate axis	Up to 24 months	Define if there is an improvement in the straightness of the condylar path by measuring the gap between the interincisive point in mouth opening and the ordinate axis in mm assessed by Modjaw
