I'm glad you are thinking about things before just doing anything that is suggested. I also have had concerns about the cubic zirconia teeth implants which is why I haven't done them (also they are more expensive than the titanium ones and usually not covered by insurance.) But, when I was working with a naturopath to prepare for the removal of the root canals and teeth implants - I asked what she thought about the metal-free teeth implants. She felt that there still could be consequences from having something placed into your bone like that and was wary of them. The dentists I had talked to about it felt overall it was an improvement from the metal ones, but some people have still had problems or they didn't do well in integrating with the bone. I think it all depends on the individual and situation. I keep thinking about doing something more permanent again - like another bridge or the cubic zirconia implants, but I have kept coming back to the simplest solution. So, I still have three little removable partial bridges. By the insurance coverage they are considered "temporary", so if they are really annoying to you, you can still usually get something else done later. My thinking was that if something else happens with a surrounding tooth, then they just add something to my partial and there is no mouth trauma from a procedure for me. I will say when I got a new set of partial dentures in the past year that I did have some pain around the gums and had to go back to have them adjusted twice to get the fit right. But, once that has been done, they have done well. I still have the cubic zirconia bridge that spans 3 teeth (one missing tooth and the two on either side have a cap on them to hold it together). I haven't had any healthy problems, but it is annoying to floss around. The little removable dentures the draw back is that food gets stuck under them and they do pinch the gums sometimes. But, if you rinse them off when you can after eating and you take them out at night, it's pretty manageable for care. So, this is a really long answer to say, that none of the options really are perfect. I would make sure if you are doing any kind of denture or bridge that you work with a holistic dentist and ask about all the different options. Some people have a method to check and see what materials would best resonate with your body. Also if you were considering the cubic zirconia implants, there is the issue with bone density. With considering the metal free bridges, I've learned that it's best if the bridge isn't too long and that it shouldn't cross the midline of the body. And just be aware that they will shave down a little bit of the surrounding teeth when they place the bridge. So the one side effect this has had for me is that I can get more tooth sensitivity in those teeth. Sometimes from hot and cold, sometimes from something too sweet. Best of luck to you. And remember to listen to your own gut reactions when different options are presented to you. Ultimately you should take all the information and make the best choice for you.
