Orthodontic treatments are not the same for everyone. The use of appliances like Herbst appliance, Hawley retainers, and so on depends on many other factors. For instance, the type of problem, age of the patient, etc., are the parameters to consider. However, these appliances should be made so that they fit firmly in the patient’s mouth. For this, orthodontists take help from China Orthodontic Laboratory. This laboratory takes measurements or impressions very keenly. After this, the specialists from this lab produce orthodontic appliances according to the impressions of every patient.
