网购牙套传照片就下单：上牙没正，下牙歪了…… - 网购,牙套 - IT资讯

日前，一则“23岁女子网购牙齿矫正器导致门牙坏死”的消息引人关注。据杭州媒体报道，一位23岁的姑娘因门牙外凸影响美观，在网上购买了隐形矫正器自行佩戴，导致一颗门牙牙神经坏死。

牙齿矫正器（俗称隐形牙套）作为一种美观又简易的新型医疗器械近年来受到不少年轻人的青睐，然而你真的相信花费不足医院十分之一的价格就可以轻松将一口凌乱的牙齿矫正整齐吗？北京青年报记者近日对网购牙齿矫正器进行了调查。

打开淘宝网搜索“牙齿矫正器”，瞬间出现上千款不同产地、不同样式的隐形牙套，价格也从十几元到三四百元不等。商家们对于产品的介绍，主要以省钱、省时、方便、副作用小等作为卖点，表示“购买隐形牙套既可以避免钢丝矫正的烦恼、美观简便，又无需反复复诊、可全程网络指导”。

顾客只需传照片就可下单

在一家出售“澳洲原装进口成人牙齿矫正器”的专营店内，北青报记者看到，在其对产品的介绍中写道，使用该矫正器分为三个阶段，单个牙套的原价为380元。也就是说，整个矫正过程下来，消费者需要购买3次，花费在1140元。

在购买须知一栏中，店家介绍“并不是所有的牙齿问题都可以使用矫正器”，因此要求消费者在购买前与店家联系，先拍牙齿照片传给对方，经对方的专业医生分析牙齿情况后，再推荐合适的矫正器。

随后，北青报记者以消费者身份联系了该店家的客服销售人员。和购买须知上提到的一致，对方要求记者先拍摄牙齿照片，称“用电脑摄像头或手机拍摄都可以，一般是上下左右正面5个角度”。

据其介绍，须分3个阶段购买牙套，每个阶段至少需要佩戴6个月。佩戴过程中不用再进行更换。“每天要戴8-10个小时，3-5个月左右会慢慢看到效果，总疗程要戴9-18个月。”北青报记者询问，佩戴过程是否还需要定期拍照给对方看，对方仅表示“不懂的地方随时联系我们”。

产品宣传与实际不符

接下来，当北青报记者提出，“怎么能看出购买的商品是澳洲原装的？”对方发来一段文字介绍，大致意思是在解释该店出售的矫正器已获得国际专利和国际CE认证，并表示在国内医院使用多年，后面还附上了该矫正器外国官网的链接。在被问道“是否有相关授权证明或国内认证？”时，对方表示“没有”。

而在一家牙套售价在20多元的网店内，北青报记者看到，网页上宣传的一款牙套是由美国齿科研究中心研制的“德萨”矫治器。产品照片上可以看到是全英文，下方还标有“USA”字样。但当北青报记者进一步询问店家关于该款牙套的情况时，对方竟改口称这是一款“国产牙套”，北青报记者询问生产厂家是哪里，对方称是“安徽生产的”。北青报记者追问厂家的具体名称，对方便不再回复任何消息。

佩戴牙套后导致上牙不正下牙歪

北青报记者注意到，有不少在网上购买了隐形牙套的消费者留言表示使用效果“不理想”，也有以“胶味重”、“不舒服”为由很快就放弃使用的。此外，还有不只一位消费者反映，牙齿矫正过程中出现同一个问题，“明明是矫正上牙，佩戴牙套后，导致两颗下门牙歪了”。不少消费者在吐糟后纷纷表示，决定放弃自行佩戴牙套，还是去正规医院更安全。（文/记者彭小菲）

光看照片就购买牙套可能发生咬合错乱

北京大学口腔医院口腔正畸科副主任胡炜首先否定了网店仅凭照片就出售牙套的行为，“牙齿矫正器应该是个性化的，因为每个人的牙齿大小、牙弓宽窄是不一样的，所以光看照片肯定是不行的。”

胡炜表示，患者到正规医院进行牙齿矫正，需要经过以下几个步骤，缺一不可：首先，需要先取石膏模型，拍X光片，诊断后得出一个针对个人的设计方案。其次，用扫描机进行口内扫描，形成数字化的三维模型，然后将模型送到生产厂家，厂家会根据医生的要求做出一个三维的矫治方案，并反馈给医生。接着，医生会根据经验判断方案是否需要修改，一般情况下都需要修改多次，才能批准制作。最后，等牙套制作完成后，患者在医生的指导下进行佩戴。

那么，私自购买佩戴牙套会造成哪些危害？胡炜表示，由于隐形牙套材料性能的制约以及牙齿受力移动的不确定性，目前使用上还需要医生去把控。戴上牙套后，一旦牙齿没有按照预设的方向移动，就很可能发生咬合错乱，从而影响咀嚼功能，也可能出现咬合干扰，导致牙齿疼痛或松动。

到正规医院矫正牙齿，一到两周需要更换一次牙套，一到两个月需要去一次医院，医生需要检查牙齿是否按照预设方向移动，从而随时作出调整。而自行佩戴牙套，一旦出现长时间错误矫正，导致牙齿歪掉或出现更严重的问题，再想挽救回来就难了。

2014年6月，新修订的《医疗器械监督管理条例》正式实施，对医疗器械的监管思路、制度设计和监管方式进行了重大调整。在此基础上，国家食品药品监督管理总局正在加快制定《互联网销售医疗器械管理办法》，显然这是针对电商和线上销售医疗器械所制定的新的管理办法。
