You can wear braces if you have porcelain teeth. If severe crowding, misalignment or anterior protrusion of the teeth occurs, and you need to reduce the number of extractions to obtain orthodontic clearance, you should prioritize the extraction of teeth wearing porcelain braces, to be able to save as many natural teeth as possible. If the lip side of the porcelain tooth needs to be bonded to buccal tubes, brackets and other accessories, you can use strong acids such as hydrofluoric acid to etch the surface layer of the porcelain tooth, rinse it with water, dry it and then use a silane coupling agent as an adhesive to bond the brackets, so that the porcelain tooth can be constantly moved to achieve the orthodontic goal under the traction of the orthodontic arch wire, and if you use the invisible orthodontic appliance, the crown of the porcelain tooth will not be affected, and it can successfully achieve orthodontic results.
