Temporomandibular disorders and orthodontics: What have we learned from 1992-2022?

•It has been 30 years since the AJODO published a special temporomandibular joint issue in January 1992. •Since 1992, a large amount of evidence-based data has been accrued over the decades. •Conventional orthodontic treatments performed with and without extractions do not cure or cause TMD. •Establishing canine-protected occlusion and attaining the coincidence of maximum intercuspation with a particular centric relation position is not evidence-based. •TMD management has transitioned from an occlusal and mechanical-based model to a medical and biopsychosocial model of care. “What have we learned…?” Clearly nothingAmerican Journal of Orthodontics and Dentofacial OrthopedicsVol. 162Issue 2PreviewI was dismayed back in 1992 to see my specialty falling all over itself to hide its collective head in the sand and try to distance itself from any responsibility for temporomandibular disorder (TMD). I am even more dismayed today reading a journal that should be balanced and thoughtful would publish this opinion piece without at least a counterpoint. The American Journal of Orthodontics and Dentofacial Orthopedics did just that several years ago—but I guess it didn’t deem having a dissenting opinion important in 2022.

Temporomandibular disorders and orthodontics: what have we learned from 1992-2022? Am J Orthod Dentofacial Orthop. 2022;161:769–774). However, the important area of how TMJ disorders impact craniofacial growth was unfortunately remised. Our goal here is to briefly update the readers in this important area. Full-Text PDF
