With regular brushing and flossing, the implant screw itself can last a lifetime, assuming the patient receives regular dental check-ups every 6 months. The crown, however, usually only lasts about 10 to 15 years before it may need a replacement due to wear and tear. However, maintaining excellent dental hygiene and using it cautiously could extend the life of the crown beyond 15 years. Mouth location is also a factor in predicting the life of a dental implant. Implants in the rear of the mouth are used more actively in chewing, which means they will likely wear out more quickly than implants near the front of the mouth.
看了三个orthodontist, 两个说要种牙,不建议把虎牙挪到前面,一个给了上面两个方案。
种牙的缺点是要等到20多才能种,种的牙可能用20年还得重新种,另外前排的骨头发育不够好的话种牙不好种。总之也是很麻烦的
种牙肯定更美观,但是功能性来说可能不如本身的牙。另外就是不是一劳永逸的,之后还得再种
有牙医告诉我的,我自己也做过research,植牙大约可以保持25年左右。如果中年植牙那基本可以保持到老了,20岁植牙的话能到50岁就不错了。不是lifelong的
也不知道怎么回事,他下边牙都长了,上面少了四颗牙,牙缝奇大无比
