In order to push the bone material out of the operating element, a special ejector has been developed which can be inserted into the lumen of the working element. In thisway,thebonematerialcanberemovedfromthelumenofthehollowosteotomes easily and without damage. The bone material then is ready to be used for autoge- nous augmentation (Figs. 10a–c). Since there is a special indication for the applica- tion of osteotomes in the posterior jaw bone at a bone quality of D3 and D4, the op- erating element was formed with an angle, thus designed to be universally applica- ble both in the front and in the posterior jaw regions. _Indications for use of the hollow osteotomes 1. Bone quality D3 or D4 2. Mucosal punch (Fig. 11) 3. Preparation of a bone cavity for a dental implant 4. Preparation of a bone cavity using a navigation template (Fig. 12) 5. Preparationandtransformationofanextractionsiteforimmediateimplantplace- ment (Fig. 13) 6. Preparation of a bone cavity and simultaneous removal of autologous bone ma- terial (Figs. 10a–c) 7. Preparation of a bone cavity with simultaneous compression (improvement of bone quality) of the surrounding bone and bone harvesting 8. Preparation and application during indirect sinus lift procedures (Figs. 13a–c and 14a–c) _Discussion Maximum autologous bone harvesting from the jaws, performed in a minimally invasive surgical procedure, is an advantage of the above-presented instrument. Another advantage is the low risk of overheating the bone compared to rotating instruments, particularly when using navigation templates due to non-existent irrigation. _Risks and side effects Vertigo may occur in the application of traumatising instruments in exceptional cases of a pre-damaged patient. The subsequent and relatively simple non-invasive treatment is performed by an ENT doctor. However, side effects can occur in all dental procedures, even in treatments with turbines, as well as in the leisure sector, for example with mountain bikers. Because these side effects occur only rarely, they are outweighed by the benefits of the method described above. _Summary Hollowosteotomesbroadenthespectrumofautologousboneremoval,especially from the jaw, while the bone structure is condensed simultaneously. They have proved effective in the minimally invasive removal of autologous bone at the same time as an exact preparation and quality improvement of the local bone of a density of D3 or D4 (Carl Misch)._ Dr.Rolf Vollmer Nassauer Str.1 57537Wissen,Germany Tel.:+49 2742 968930 Fax:+49 2742 2547 info.vollmer@t-online.de _contact implants 2013-01A0019 Collagens and suture materials for dental surgery PARASORB Sombrero® Absorbable Membrane-Cone PARASORB RESODONT® Absorbable collagen membrane PARASORB® Cone PARASORB® Cone Genta Collagen-cone for the treatment of extraction sockets RESORBA® sutures The optimal suture for each indication RESORBA Medical GmbH Am Flachmoor 16, 90475 Nürnberg, Germany Tel. +49 9128 / 91 15 0 Fax +49 9128 / 91 15 91 www.resorba.com SILVERSPONSOR OF THE AD
