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

Study Overview
=================
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.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Gap reduction between the interincisive point in mouth opening and the ordinate axis | 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 | Up to 24 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Condylar courses homogeneity | Qualitative comparison of the homogeneity of the condylar courses before and after treatment | Up to 24 months | 
| Condylar courses symmetry | Qualitative comparison of the symmetry of the condylar symmetry before and after treatment | Up to 24 months | 
| Condylar courses straightness | Qualitative comparison of the straightness of the condylar symmetry before and after treatment | Up to 24 months | 
| Amplitude of the condylar path | Virtual path length in mm assessed by Modjaw | Up to 24 months | 
| Straightness of the condylar path | Y-axis deviation in mm assessed by Modjaw | Up to 24 months | 
| Adverses events | Adverse events will be assessed before and after treatment | Up to 24 months | 
| Pain assessment | Pain is assessed by an analogic visual scale from 0 (no pain) to 10 (maximum pain) | Up to 24 months |
