Augmentacija “ring” tehnikom – prikaz slučaja

The bone ring technique is a surgical methodology invented in 2004. by dr. Bernhard Giesenhagen (Kassel, Germany) that allows bone augmentation and implantation in a onestage procedure. Compared to the more conventional two-stage approach, the main advantage of the bone ring technique is that of significantly reducing the treatment time by several months. The bone ring technique enables vertical/horizontal augmentation and formation of new bone, thereby simplifying the surgical treatment of 3-dimensional bone defects. According to the original approach, the augmentation is performed with autologous bone rings, which are harvested intraorally (mostly from the chin area, alternatively from the retromolar area or palate) with a trephine. The bone ring is then transferred to the trephine drill-prepared recipient site. The implant bed is thus prepared in the local bone through the ring opening, and the implant is inserted through the ring. Cancellous bone collected from the donor site during or after harvesting of the ring block can be used as additional augmentation material. The bony integration of the bone ring and implant occurs via the surrounding bone during the following few months. In this case we will present a 43 year old female patient who lost her tooth number 45 five years ago due to a chronical periapical lesion. As we could see on the CBCT-scan (Cone Beam Computer Tomography), the bone defect which was left behind was ideal for the bone ring technique. Using this augmentation technique we simultaneously augmented the area and inserted a Nobel Biocare (Kloten, Switzerland) implant. We used PRGF (Growth factorrich plasma) membranes to cover the recipient site and and ensured tension free closure using polypropylene sutures.
