Hello! I'll do my best to answer your question!
Sir, I would see what the Dentist who did the 3 implants for you would suggest - if that is possible to see him or her, and get their opinion, as the foremost authority here.
Here is why. A bridge would undoubtedly be fine or good or better, perhaps great! But, if there is ample room for yet another implant where the root of the tooth is which needs extracting? I'm of a strong opinion, that using the same Dental
personnel to evaluate, and assuming there is room (there likely "will be"), then they could use the same lab
, and same brand of implant, and same techniques, etc. And, I don't want to make this sound too complicated - but the same hands doing the work, & with the same materials will tend to give you a much more desirable & esthetic front four teeth that will ALL look harmonious & at their very best!
Sometimes, a second set of hands working on such a situation, will inadvertently give you a 4th tooth which looks just a tid-bit off from the rest...
I hope the above makes sense. Please let me know if you should have any additional concerns - OK?
