Wisdom Teeth: Implant Substitute?

[MidsummersEve]

Hello there everyone. I am in the process of signing up for my new health insurance cycle this coming fiscal year. I need to make a decision about a medical spending account, and the decision is how much money I should put into it.
This question however lies on a much deeper and more painful topic.

I have a long gloomy dental history. I have done better since I've grown up, started brushing and flossing regularly and not avoiding the dentist.
My history however has left me with molars that have multiple fillings each, sensitivity(some very deep filings) and even one crowned root-canal. My last dentist tried to pressure me into cutting out my wisdom teeth, but for the first time in my life I really listened to my mother. She told me everyone in our family has has had them and they've developed cavities at most, but nothing else. This led me to start thinking I could use these real teeth in the future to replace some of my bad-habit results.

I have wondered for some time now, if I should keep my wisdom teeth and when the time comes simply remove my molars. One tooth is on the verge of a root canal because the recent "Redone" filling by my EX-dentist is so sensitive that I haven't eaten anything other than pudding on that side of my mouth for over 6 months. I haven't seen a lot of information about this topic online and so I am digging a little deeper and asking for a few educated guesses.

I'll take it to the next level even. People say wisdom teeth decay easier and are harder to reach. If these teeth are pulled into the place of my former molars AND if I get sealants for any really deep tooth crevasses, I feel this is a more natural option than getting more fillings, root canals, crowns, and then eventually implants down the road.
Heck I'll even risk guessing it's cheaper in the long-run than getting all the work above over time.

Any thoughts?

I've read a few articles regarding wisdom teeth replantation/autotransplantation, but I'm not sure of how good / predictable the results are. Some articles suggest that the success rate is about 50% to 80% over 5 years. There was a case recently in one of the JCDA journals, and the result looked okay.

One other option might be having orthodontics to move the teeth into position. Here's some articles that I found with more info:

It sounds like this procedure has some very specific requirements, and you would have to find a dentist experienced in doing it. It looks like most successful cases were done in younger patients so that might limit this procedure to that age group. In some cases keeping wisdom teeth around can have some advantages, but in the majority of patients that I see they tend to be more problems than they are worth. Most people don't want to go through the expense of orthodontics to bring these teeth into position where second / first molars are missing so ultimately they create problems in terms of decay, gum disease, and infection so removal tends to be the final outcome.
