Sinus Lift: Graft or No Graft?

In the vast majority of my cases, Sinus Lift was performed on total edentulous. Patients who have used Total Prostheses for many years. Soon the need for bone was great. I believe, but for the cost, few times I realized that before implant installation and after radiographic confirmation of bone neoformation, we should, via trephines, obtain a sample of the newly formed material and only after implanting the implants.

Some authors say that simple sinus membrane displacement and bleeding would already be sufficient for bone neoformation. Few and rare are studies with this type of technique. So it lacks proof. Other studies say that autogenous grafts are equal in final outcome compared to the use of lyophilized bone. Therefore, there are countless studies that preach the use of lyophilized bone as the provider of the best result. But they are not standardized studies, do not have long periods of follow-up and many doubts persist. Coupled with all this, a large number of scientific studies in this area are sponsored by the manufacturers of the products, this fact, which at least makes the results suspicious. For the great majority of us, Latin American professionals, the use of "Growth Factors", due to its high cost, is still not feasible in the clinic. But this also needs further studr
