The maxgraft® bone ring technique is a surgical technique that enables the dentist to achieve vertical bone formation and insert implants at the same time. The allogenic bone ring, a prefabricated ring made of processed human donor bone, allows for bone to be augmented and implants to be inserted at the same time in a single procedure and can be used for almost all indications (including sinus lift). The integration of the bone ring and the implant into the bone is carried out using the surrounding vital bone. The benefit of this is that the body’s own bone does not have to be removed and the treatment time is shortened by several months and further procedures because the bone formed at the same time as the implant is inserted.
