Pregnancy and Dental Implants

Petra, a dental implant patient, asks:

I am a dental implant patient and I recently experienced an implant
failure in a rather unexpected way. I had the dental implant (lower jaw in the
back) for about 4 years without any complications whatsoever.

However, during my
second pregnancy and while breastfeeding it started to become a bit
loose. The dentist thought the abutment was loose and tried to tap off
the crown to screw it tight again. However, the crown would not come
off.

It seems that the wrong (permanent instead of temporary) cement
was used originally. An x-ray showed that the dental implant was completely
fine, no significant bone loss, no inflammation. A few weeks later the
dental implant was loosened and came out with the crown still cemented to it.

My question is did my body reject the dental implant after 4 years because
of my pregnancy? Or did the dentist pull too hard when he tried to
remove the crown? What happened? Is there any data regarding pregnancy and dental implants?

  1. Your implant failed prior to the dentist trying to remove the crown. It may never have fully integrated to begin with, but without the initial information, we’ll never know.

  2. I diagree with Dr. Kim. Using your description alone, there is no way of knowing when your implant fixture failed or what caused it to fail. Many times, restorations (caps)come loose due to abutment screws partially backing out possibly due to a failure to use a torque wrench when initially placing the screw. Banging off a loose restoration can place significant stress levels on the underlying implant fixture which can lead to failure. It is a much safer bet to scrap the restoration and section it off rather then risk damaging the underlying implant fixture. Once again, it is impossible for anyone on this blog tp tell you what caused your fixture to fail; they would need to examine you and review your past radiographs etc.

  3. Since using a torque wrench; my abutment screws have never loosened. I have never seen a crown loosen without the abutment screw being loose. I used to hand tighten them and the screws did loosen occaionaly. I always put fermit in the screw holes of the abutment. If the screw hole does not face the facial of the crown, I can usually drill an access hole thru the crown and retighten the screw with a torque wrench then place fermit in the screw hole again and cover the hole with composit. If this is not possible, I always cut the crown off and remake. The most important thing is not to damage the fixture. I never bang on the crown.

  4. Safest way to remove cemented restoration from tooth or specially implant is to cut restoration, unless dentist is sure about the use of temporary cement or restoration is obviously loose.

  5. Have you seen your dentist since “it came out”? I am just wondering if the implant body came out or the abutment came out. Just a thought. It seems “a couple of weeks is a rather short time for implant failure secondary to trauma from the dentist.

  6. Hi there,

    I have recently been told that I need to have 2 implants due to an infection and needing to replace my crowns. My husband and I are trying to conceive for our second baby, and was wondering what advise you can give? Should we wait until after the whole procedure, or could be conceive after the initial consultation?

  7. Wait, dental implants are elective surgery. There really isn’t great literature on effects of things on babies (it is really difficult to get the moms to agree), but you can always get the implants later. It may cost you more (need for grafting etc.)

  8. I have dental implant in number six spot. It has been draining for a couple of months on the facil side. Infection I asume. I am 20 wks. pregnant and wondering will this affect my baby. Does the implant need to come out wright away. It has only been done for about three years.

  9. Hi,
    I have two implants in my mouth, one is 2 years old, the the one about 8 months. I’m thinking of getting pregnant in somewhat a year (or two), and I wonder if implants can damage fetus development in any way or cause any birth defects or any diseases??? In other words, can it harm the baby?
    Thank you very much in advance,
    Katya

  10. Dear Petra, An implant usually fails within months of placement due to overheating of bone during osteotomy (drilling) preperation and infection, and later on i.e months to years due to too much occlusal (bite) force. The bite force issue is related to bone density, implant surface, thread design, width of crown(s) or bridges and not wearing a bruxing appliance .
