I like to find out in case of dental implant failure, what recourse do we have? Did anyone manage to get any full/ partial refund? In Malaysia, normally there aren’t any kinds of black and white to be signed when seeking any dental treatment. The doctor may put the fault on you that your body couldn't accept the implant well

As in my case, I did both dental implant and bone graft. After a period of 7-8 months, no bone was formed from the bone graft and the implant was protruding.
I did consult another specialist and he opined that the implant was failure on ground that first, no bone was formed, secondly the positioning of the implant was wrong.
My dentist advice is to redo the whole thing for me which I am kinda of reluctant (prefer refund by the way) for reasons being:
- he isn't an implant specialist  after I found out this from another doctor (well, a lesson learned here). A lot of dentists in Malaysia claim they are specialists but in fact they are mere general practitioners. What they did was by just attending some courses on dental implant. There aren't any stringent regulations which guard this matter in Malaysia. Any dentist can call himself specialist with just some certifications without going through extensive training and practice
- he lacks of experience
- there wasn't any CBCT scan or computer guidance carried out prior to and during the treatment to analyse the jawbone and condition of the implant. In fact, the whole treatment was just mere guessing (another lessons learned)

Anyone has similar experience? Mind to share?
