Body<br />

Objectives<br />

Craniomandibular dysfunctions (CMD) are a predominant, controversially discussed subject in<br />

dentistry. As the symptoms are multifactorially conditioned, one therapy in most c<strong>as</strong>es is not<br />

enough.The conventional MRI is known <strong>as</strong> the best not-inv<strong>as</strong>ive medical imaging to display<br />

the temporomandibular joint (TMJ). The aim of this study w<strong>as</strong> a systemic literature review.<br />

How much is MRI influencing therapy for patients witch CMD. Respectively which therapeutic<br />

consequences can be drawn from MRI.<br />

Material and Method<br />

Literature research h<strong>as</strong> been made in electronic data datab<strong>as</strong>es like Medline or Pubmed,<br />

followed by an additional manual search in different professional journals. All the citations<br />

were checked independent of two persons using eligibility criteria. The data rating happened<br />

in tabular comparison of the survey contents. Additionally the surveys were analyzed for therapeutic<br />

effectiveness and the level of evidence.<br />

Conclusion<br />

In conclusion 54 surveys fulfilled the eligibility criteria. The therapeutic significance, which is<br />

awarded to the MRI is different and can be cl<strong>as</strong>sified in four categories:<br />

- Differentiated statements to the therapeutic significance of MRI<br />

- MRI for evaluation of surgeries<br />

- MRI for evaluation of conservative therapeutic me<strong>as</strong>ures<br />

- MRI for evaluation of the relationship between orthodontics and CMD<br />

-<br />

Discussion & Conclusion<br />

The therapeutic significance, which is awarded to the MRI in the implemented surveys, is<br />

various but mostly vague formulated. Noticeable are incomplete described surveys contents.<br />

Referring to the modell of Fryback et al. (1991) the therapeutic significance is constituted in<br />

some surveys, a patient-relevant benefit is not. The rank of evidence is restricted in the existing<br />

literature, the retrospective investigations predominate.<br />
