Originally on my website I had a section about how to extract teeth properly. The Hal Huggins extraction technique, it's in his book and here:

That was the technique I had on my front tooth. It does work but it wasn't entirely successful and I had to have a further surgery 18 months later to fix the small problem that was left. But regardless of how successful the technique is, drilling on your bone, especially your upper jaw is less than pleasant. The technique I had at the clinic i went to, basically involved cutting the bone away with hand tools, and this is a lot lot more tolerable, and seems to be a lot more successful. But back to your question, yes, the ligaments need to be removed. Otherwise how is the bone supposed to know to start healing ? I think you practically guarantee problems (especially with the back teeth) if they aren't removed. But the removal technique is important, done incorrectly it just wont heal. For example if a dentist just drills the ligaments away, he is likely to cook and fracture the bone at the microscopic level and it probably won't heal well, if at all.
As for implants, metallic or night the concept like
root canal might be flawed. At the clinic I went to, they basically had the impression that implants were a great way to kill yourself. If anyone knows its probably these people since they do thousands of cavitat scans. The reason she explained was because you create a pathway deep into your bone which bacteria can travel down. Normal teeth don't have that type of attachment, and they also have a fluid which goes down the dental tubules and out the root of the tooth root surface which helps to keep them clean, which of course a dead tooth or implant does not have. The answer on this is, i really dont know. There is hardly any serious research on the safety of implants, at least that I can find. The titanium ones ignoring the fact of whether you have a sensitivity to it, because of the way they are designed in sections, with the tooth root, the abutment and then the tooth ontop, there's normally a microscopic gap where bacteria can thrive. Because of this its common for bone loss to happen to the 1st or 2nd thread on the implant, which really isn't good. Google the microgap issue, you'll find info on it. The zirconium ones don't suffer from this problem, so might be better in that respect. I just don't know, an implant is something I wanted to replace my missing front tooth. Right now I just have a temporary.
A bridge is a safe way of replacing missing teeth. If u wanted this option I would go for the Maryland type, since they are less destructive to the adjacent teeth.
I am glad you found my website useful :)
