Aligner Trimming using milling and laser machines - Pros of Milling
Trimming aligners by laser and milling machine are two different methods used to shape and finish dental aligners.
However, here are some potential benefits of milling clear aligners:
Greater precision: Milling machines can produce highly precise cuts and shapes, which can be especially important when creating clear aligners that need to fit precisely over a patient's teeth.
More efficiency: Milling machines can be faster and more efficient than laser cutting, especially for larger or more complex designs.
Greater versatility: Milling machines can be used to shape a wider range of materials than lasers, including harder materials such as metal and ceramic, i.e. milling machines can be used for other parts like crowns, bridges, etc.
Cost-effectiveness: Milling machines are generally less expensive than laser cutting equipment, which can make them a more cost-effective option for smaller dental practices or labs.
Reduced risk of thermal damage: Laser cutting can generate a lot of heat, which can cause thermal damage to the material being cut. This is not a concern with milling machines, as they use a physical tool to remove material rather than heat.
Insurance for operating facility with laser machines tend to be more costly.
Long term maintenance is simpler and cheaper for milling machines.
Ultimately, the decision between milling and laser cutting will depend on the specific needs and preferences of the dental professional, as well as the requirements of the individual case. Both methods can produce on-par high-quality clear aligners when used correctly.
