Patients in the clinic always ask: “What kind of braces are good for me to wear”. In fact, various orthodontic appliances have their own characteristics, and various technologies have different development ideas, but for orthodontics whether Invisalign or general orthodontic treatment requires good orthodontic fundamentals, Invisalign for the control of complex cases also need fragmented arch or implant support with. All of these techniques are chosen to serve the needs of the patient and the facial shape of the teeth. However, as long as the orthodontist is well trained in the system, he or she can do a perfect job with any kind of aligner, and the best aligner for an irregular doctor may not necessarily not achieve the desired result. For example, not necessarily very appropriate: just like we go to a place, we take different means of transport, we will eventually reach the end, just the process of feeling different, the car, Charly, BMW, Cadillac which can be, the process of enjoyment and feeling slightly different, including the feelings of the passenger and the driver, just like the feelings of patients and doctors. The patient will choose from the comfort and aesthetics, but the doctor will also consider the patient’s deformity, tooth position, facial shape, TMJ and other aspects. Because different brackets or techniques have different characteristics, it is necessary for the doctor to use different data on the aligners to achieve the best results for the patient. So the choice of braces is a matter for both the doctor and the patient, but if you go to the hospital please trust your orthodontist who will give you the right aligner based on your deformity, follow-up time, the aesthetics of your braces, your financial situation and your personal requirements in many ways.
