Are you saying it is because of this the reason for your results ? If it is then fair enough but if you are just saying it to find as many possible reasons for failure then that's wrong. Also you said 8 in total doing extractions. It's 1 tech does all the extractions for 1 patient. You need to be precise and if you want people to trust your opinion then you need to state what is true as well because the moment you make up certain points you lose credibility and infact most people will stop listening or caring about your opinions. It's simple now. Stop these posts , get to your 12 month mark, consult some doctor only clinics for repair and go for it.
