Abstract: Methods for forming dental appliances with laser marks. The methods may include identifying a target marking area of a dental appliance to receive a laser mark, and identifying a laser access area on a surface of the dental appliance. The methods may also include forming a surface texture to disperse laser energy received at the laser access area to form the laser mark in the target marking area.
