I have 2 implants right next to each other on teeth 29 and 30. I'm wondering what is the best way to do the crowns?

i think if you make them fused together , you will have more strength, and if you make them screw retained would help,that way you can have a good service every time you require,the doctor will remove the screw and remove crowns give service and will set them in again. I hope this helps.

You can wait for the crowns separately but there are advantages to doing them both. The porcelain will match better and you will have a balanced bite (hopefully having a molar on the other side). With a balanced bite on both sides, there will be less stress versus the single implant if done separately. Both is best.
