| Clinical Question |

| Clinical Bottom Line |
At this time, orthodontic treatment has not been shown to be effective in decreasing TMD symptoms. |

| #1) 20614447 | Luther/2010 | Adults (≥18yrs) with 2 or more TMD symptoms | Systematic Review | | Key results | Of the 284 records identified, only four articles included data useable for a meta-analysis. Of these four articles none met the inclusion criteria, so none were used. The four articles either did not provide a control group or did not use orthodontic therapy. In one noteworthy article, disc position was not altered by orthodontic therapy; however change in TMD symptoms was not reported. | |

Comments on
The Evidence |
The Luther article followed the Cochrane systematic review guidelines, and therefore applied stringent criteria in the inclusion of meaningful data. As none of the available studies met these inclusion criteria, no conclusions could be reached. |
| Applicability |
Orthodontic treatment has not been shown to decrease symptoms of TMD. Therefore, orthodontic treatment should not be recommended as a treatment plan for the purpose of alleviating TMD symptoms in a clinical setting. Patient’s TMD symptoms might decrease, stay the same, or get worse as a result of orthodontic treatment. Additional research and novel orthodontic therapies should continue to be assessed. |

A PubMed search performed November 2017 found two more recent systematic reviews which support the conclusion that there continues to be no correlation between orthodontic treatment and temporomandibular joint disorders (TMJ). Fernandez-Gonzalez, 2015 (PMID 26155354) and Dym 2011 (PMID 22117948) conclude that orthodontic treatment has not been shown to be effective in regard to either the indication of, or decreasing symptoms of ,temporomandibular joint disorder. | |
