Modification of an extended total temporomandibular joint replacement (eTMJR) classification system. Br J Oral Maxillofac Surg. 2022 Sep;60(7):983-986. doi: 10.1016/j.bjoms.2022.03.011.

High-volume TMJ surgeons were asked to score 20 separate eTMJR devices using the updated classification system, and inter-rater variability was calculated. Using the modified classification system developed, a Conger's kappa (κ) coefficient of 0.53 was returned, suggesting moderate to good levels of agreement. The final classification system was then developed in a series of standardised graphic illustrations as visual representations of the different subcategories of eTMJR devices.enCopyright © 2022 The British Association of Oral and Maxillofacial Surgeons.
