植牙 V 杜牙根 (一) Implant vs root canal treatment part 1

現在因失去牙齒已用植牙替代己非常普遍，不少病人也會問一個問題:"如果我的牙齒壞得那麼嚴重，不如直接脫了它然後植牙?"我同意這是一個很合理又值得探討的問題。

考慮因素:

1. 植牙和杜牙根的成功率 

    在這幾篇文章裏
   (Eur J Oral Implantol. 2009 Autumn;2(3):201-8., Clin Oral Implants Res. 2007 Jun;18 Suppl 3:15-9., J Endod. 2009 Jul;35(7):930-   7.   doi: 10.1016/j.joen.2009.04.023) 

      比較了杜牙根和植牙的成功率，發現:

   - 杜牙根成功率約在93%  (10年)
   - 植牙成功率約在82-94%  (10年)
   - 重杜牙根 (即是同一隻牙第二次杜牙根)成功率約62.9% (6年以上)




你會怎樣選擇?


   總結:
1. 杜牙根成功率與植牙相約
2. 重杜牙根長遠成功率大幅減低

在杜牙根成功率與植牙相約前提下，還有甚麼因素要考慮呢? 
留待下回分解。

Now it is very common to replace the teeth with dental implants because of the loss of teeth. Many patients will also ask a question: "If my teeth are so bad, why not take them off and implant them?" I agree that this is a very reasonable and Issues worth exploring.



Considerations:


1. Success rate of dental implants and root canal treatment


     In these articles

    (Eur J Oral Implantol. 2009 Autumn; 2 (3): 201-8., Clin Oral Implants Res. 2007 Jun; 18 Suppl 3: 15-9., J Endod. 2009 Jul; 35 (7): 930- 7 .doi: 10.1016 / j.joen.2009.04.023)


       Comparing the success rates of  root canal treatment and dental implants, we found that:


    -Root canal treatment success rate is about 93% (10 years)

    -Dental implant success rate is about 82-94% (10 years)

    -The success rate of  retreatment of root canal treated tooth (that is, the second-time root canal treatment of the same tooth) is about 62.9% (more than 6 years)



How would you choose?



   To sum up:

1. The success rate of root canal treatment is similar to that of dental implants

2. The long-term success rate of retreatment of tooth has been greatly reduced


Under the premise that root canal treatment success rate is similar to dental implants, what other factors should be considered?


Save for the next break.
