Movable appliances are usually suitable for minor dental problems, such as overcrowding or malocclusion, while fixed appliances are more suitable for some more complicated dental problems, such as severe tooth irregularity, jaw opening or closing. The following is a more detailed comparison between the two devices.
The fixed appliance needs to be firmly attached to the patient's teeth to maintain a constant force and adjust the direction of the teeth. Therefore, patients need regular adjustment and maintenance. In contrast, the movable appliance is detachable, and the patient can take it off at any time as needed. This design makes the movable appliance cleaner and more hygienic, and it is more convenient for patients to eat or brush their teeth.
Fixed appliances need to be installed and adjusted by professional medical staff. Patients need a long treatment process, and fixed appliances often need to be matched with other appliance materials, such as springs and rubber bands. In contrast, the removable appliance can be directly removed and replaced by the dentist under the initial local anesthesia, and each treatment only takes a little time.
Fixed appliances need strict sanitary maintenance. Because the appliance itself is an object fixed on the teeth, and the patient needs to be diligent in cleaning, otherwise it will lead to bacterial infection, oral odor and other problems. The movable appliance will not have this problem, because it can be disassembled and cleaned frequently without affecting daily oral hygiene.
To sum up, fixed appliances and movable appliances have their own advantages and disadvantages. Doctors need to evaluate the specific situation of each patient and choose the most appropriate correction method to achieve the best treatment effect. No matter which appliance is chosen, patients need to follow the doctor's advice, use it carefully according to the doctor's advice and insist on treatment to help them get beautiful and healthy teeth.
