GBR for Extensive Defect Around Implants

Even when there is an extensive amount of bone loss around teeth planned for extraction (1), we can still employ immediate placement provided we follow biological and surgical principles that have been described in the literature. In this case, once 28 and 29 were extracted, a significant defect was present by both sockets. Implants were able to be placed in 28 and 30 (2) and GBR was employed using DALI cortical-cancellous particulate graft (3) and OsseoSeal collagen membrane (4). Despite the extensive defect, we were able to regenerate bone around the implants which successfully integrated (5).

What approach would you have felt comfortable taking in this case?

I would have used a very similar approach using different materials, purely operator preference, except that I would have placed healing abutments for a single stage protocol. I would probably not use a membrane here but instead utilize a connective tissue graft as a sort of “Poor Man’s membrane” which will also augment the mucosa surrounding the fixtures. While I would have also used a particulate graft of some sort I will also confess that it is likely just a feel good thing because these fixtures in this case would be fine without a graft and soft tissue augmentation is most likely more important for long term stability.

true to the philosophy you have expressed many times before :slight_smile:
