Adult patients seeking orthodontic treatment are increasingly motivated by esthetic considerations. The majority of these patients reject wearing labial fixed appliances and are looking instead to more esthetic treatment options, including lingual orthodontics and Invisalign appliances. Since Align Technology introduced the Invisalign appliance in 1999 in an extensive public campaign, the appliance has gained tremendous attention from adult patients and dental professionals. The transparency of the Invisalign appliance enhances its esthetic appeal for those adult patients who are averse to wearing conventional labial fixed orthodontic appliances. Although guidelines about the types of malocclusions that this technique can treat exist, few clinical studies have assessed the effectiveness of the appliance. A few recent studies have outlined some of the limitations associated with this technique that clinicians should recognize early before choosing treatment options.
寻求正畸治疗的成年患者越来越受到美观因素的驱动。这些患者中的大多数拒绝佩戴唇侧固定矫治器，而是寻求更美观的治疗选择，包括舌侧正畸和隐适美矫治器。自Align Technology公司于1999年在一场大规模的宣传活动中推出隐适美矫治器以来，该矫治器受到了成年患者和牙科专业人士的极大关注。隐适美矫治器的透明性增强了其对那些不愿佩戴传统唇侧固定正畸矫治器的成年患者的美观吸引力。尽管存在关于该技术可治疗的错牙合类型的指南，但很少有临床研究评估该矫治器的有效性。最近的一些研究概述了与该技术相关的一些局限性，临床医生在选择治疗方案之前应尽早认识到这些局限性。
