Onlay Block Graft
At Dentalcare Plus London & South East, we perform the Onlay Block Graft procedure in house.
After a tooth extraction there is always a 25% chance of horizontal bone resorption (loss), followed by some vertical bone resorption (loss). This varies from case to case. This natural event may lead to cosmetic problems in the aesthetic area, since implants require a minimum of 2mm of bone on the buccal plate.
Without sufficient bone, cosmetic problems, recession of the gums and exposure and loss of the implant may occur. In cases of severe horizontal or vertical resorption, onlay block graft surgery may be the only surgical technique available in order to restore the original anatomy of the site. In an onlay block graft surgery, an autogenous block graft is harvested (traditionally from the ramus of the mandible) and fixated in the defective site.
