Hi tazey,
I don't have implants, but your question about how to know that you've got the right dentist is almost universal and a very good one.
When it comes to dentistry, it is all about how do you feel about the dentist. Everybody has different preferences and things that are important to them when it comes to dentistry so the question is: what is important to you and do you feel like the dentist you have chosen is providing you with that?
For me personally, being taken seriously, feeling like they are listening to me, being in charge - having the possibility to get up of the chair or having a break if I like, spreading the treatment so that we go at my pace, not being rushed, those are my personal important things. So if I was to find a dentist, I would want to get in touch via email beforehand and ask how they work. Also, are they all about treatment or willing to give me an appointment just for a chat, to build some trust? Again, those are things important to me, yours may be different, but a good dentist is one that gives you what you need.
I guess the first visit is always you giving a bit of trust in advance and checking whether it was worth it. Being willing to look around a bit and change if you don't feel comfortable straight away, may be a good thing too.
Your journey has been a long and exhausting one, I am truly wishing for you to find a dentist who can accommodate your needs and help you to get where you would like to be.
All the best wishes and keep us posted
