Obstructive Sleep Apnea is a highly prevalent respiratory disease linked with increased morbidity and mortality, reduced quality of life and increased economic costs if not treated. Oral Appliances are an emerging treatment option for Obstructive Sleep Apnea. This review concludes that many oral appliances marketed as “custom” include modifications and prefabricated items, and therefore do not meet the definition of “custom” oral appliances. This misclassification could hinder accurate characterization and appropriate utilization of oral appliances that do fulfill the definition of custom. To better inform clinical utilization of custom oral appliances, we propose further refining the custom oral appliance classification into semi-custom and precision-custom.

This misclassification could hinder the accurate characterization, evaluation, and appropriate prescription of oral appliances. To better inform the clinical utilization of custom oral appliances and to more closely align sleep medicine with the benefits of personalized medicine, we propose that the custom oral appliance classification be further refined into semi-custom and precision-custom categories.
