Conclusion
There is a lack of evidence on the effectiveness of different treatments for DDwoR. Although this overview showed differences in pain control and improvement in mandibular function between the treatments studied, especially for open surgery, it is not possible to state the best treatment, indication, predictability and limitations of each one per DDwoR profile. The comparative effectiveness of conservative and invasive treatments for DDwoR remains uncertain due to the low methodological quality of the secondary studies analyzed in this overview and the risk of bias of the primary studies reported by the authors. In this sense, new RCTs and repeated comparisons between types of treatment for DDwoR in different populations and TMD profiles are needed to guide professionals and patients among clinical and surgical options to better treat internal derangements.
