Relating to the sale, design, and manufacture of orthodontic devices.

HB 4070 requires dentists to conduct in-person examinations and review diagnostic imaging (like x-rays) before patients can receive orthodontic devices such as braces. It prohibits selling or manufacturing these devices unless a dentist has provided the required exam and issued a prescription, or the seller has written confirmation from a dentist. The law directly affects dentists, orthodontic device sellers, and patients seeking orthodontic treatment. Key provisions mandate specific medical evaluations to identify conditions like gum disease or dental fractures that could make treatment unsafe. This replaces current practices by adding mandatory dentist oversight for device sales and design.
