how long are you planning on waiting after exos prior to performing GBR for 45-47 sites? I'm not sure of your exact plan but I suggest extract first. then perform GBR after 2 months at minimum so that soft tissue has formed over the sockets. This way you can achieve primary closure and also gain KT.
one of the critical factors in success of GBR is primary closure. Yes, tacks or screws are great and I use them for most GBR cases but without proper handling of soft tissue, we are doomed for failure. This includes suturing as well.
I wouldn't use non-resorbable membrane in this case. Use collagen membrane but make sure it does not get exposed. This may seem like a simple concept getting primary closure but most GBR failures are due to improper technique.
We covered all these details at the last GBR course a couple weeks ago at Bites. next course is coming up on Saturday, September 29 at Bites in Burnaby.
