I am often asked by friends to make porcelain teeth for him/her, the purpose of which is to look good for themselves. For these friends, I usually politely decline and tell them the reason for this. What kind of people need porcelain teeth? Before answering this question, I quote part of the textbook: porcelain dental indications: 1, fluorosis, discolored teeth, stained teeth, tetracycline teeth, conical teeth, enamel hypoplasia, etc., should not be restored by other methods; 2, cavities or dental defects and can not fill the treatment; 3, anterior teeth misalignment, torsion and not suitable or can not do orthodontic treatment; 4, the need to do porcelain bridge retainer abutment. Contraindications to porcelain teeth: 1, adolescent permanent teeth because they are not fully developed, the pulp cavity is wide; 2, the tooth is too small to obtain sufficient retention shape and resistance shape; 3, patients with severe occlusion tight, deep overlap in the absence of correction and can not obtain sufficient clearance. In fact, in the principles of oral restoration, the first requirement is to restore the form and function of the teeth, but also to preserve and protect the dental tissue. For the front teeth, my personal view is: function is the main, aesthetic supplement (of course, for some special occupations can make exceptions, such as actors, teachers, etc.), if overemphasis on aesthetics, the cost will certainly sacrifice part of the function, but also in the future to affect the health of natural teeth, after all, according to the current level of technology we can not reach the restoration and the body of the tooth 100% fit, porcelain teeth can not be like natural teeth If there is any problem with the abutment or porcelain crown, it means that the restoration will be rebuilt, so porcelain teeth are not a one-off. In summary, porcelain teeth should be done sparingly or not at all. Now, almost every day we are removing many bad restorations, it is really very painful for patients, friends with bad teeth, please do not be fooled by the rhetoric of some black-hearted doctors. If you do need porcelain restoration, we recommend that you go to a qualified hospital, so that medical hygiene and medical technology will be guaranteed, and more importantly, the doctor will give you reasonable advice to achieve good treatment and restoration results.
