Teeth implant placing during pregnancy

First off, congratulations! It is usually advised to not have dental procedures done during pregnancy. Pregnancy can cause many dental challenges already. However, if the implants are already placed and in good condition, it may be okay to proceed. Please however, check with your obstetrician before proceeding. Every patient is different, just like every pregnancy is different. The health and well-being of your baby is, I'm sure, your foremost concern. Your obstetrician will have some good insight for you.

It is generally recommended to have any non-emergent dental procedures after pregnancy. Although as mentioned in the other comment, if the implant is already exposed and only requires an impression, then it may be ok to proceed. 

Dear Andka, the best is ask to your doctor, but always is more safe with your pregnancy advance. I think with your weeks it's ok because depend of your implant position will be an easy impression and days after test the crown and if everything goes right, place the crown. It's a easy procedure.
