Occlusal Guard Hard Appliance - CDT Code Guide
Overview
CDT Code D9946 refers to a removable dental appliance designed to minimize the effects of bruxism or other occlusal factors. This appliance provides partial occlusal coverage, such as an anterior deprogrammer, and is not intended for use with sleep apnea, snoring, or TMD appliances. The occlusal guard is typically used to protect teeth from the wear and tear caused by grinding or clenching, commonly known as bruxism. Dental professionals may recommend this appliance to patients who exhibit signs of excessive tooth wear or jaw discomfort due to occlusal stress. The appliance is custom-made to fit the patient's dental arch and is removable for convenience.
