Simply Natural. Long-Term Reliability. For life Ring technique Par t 1: Vertical bone augmentation and immediate insertion Bernhard Giesenhagen and Orcan YükselPLAN In the case of advanced atrophy or jaw defects, extensive vertical bone augmentation is often unavoidable to enable patients to be fitted with implants. These implantological procedures are usually two-stage and are very time-consuming for patients. The method of grafting bone rings developed by Bernhard Giesenhagen in 2004 makes it possible to augment the bone and insert implants in one single session. There are virtually no limitations to the indications for applying this technique. Compared with the classic, two-stage augmentation using bone blocks, the bone ring technique shortens the overall treatment time by several months. The method will be clearly and graphically presented in a multiple- part series of articles with the aid of various case studies. In the first part of the series, a case is presented to illustrate the procedure step by step in the anterior maxilla. The conditions required for successful application of the bone ring technique, in terms of achieving a restoration with long-term stability. THE METHOD AT A GLANCE First mark the bone ring with a trephine drill (Helmut Zepf Medizintechnik) at a suitable intraoral donor site – in this case the chin area. The central hole of the ring is drilled into the bone before the transplant is harvested. Only after this step, the ring graft should be dissected and harvested with the trephine drill. Insert the detached bone ring into the prepared receptor site. Then prepare the implant site in the local residual bone through the ring opening. Insert the Ankylos implant, at the same time fixing the bone ring. Cavities should be filled with autogenous bone chips or bone regeneration material. Cover the wound with a membrane and carry out primary wound closure. While the grafted bone ring firmly attaches to its surroundings, the implant osseointegrates in the local bone and in the bone ring. After an appropriate healing period, fit a prosthetic restoration onto the implant in the usual way.

  2. 2. Micromovements at the Implant-Abutment Interface: Dr Paul Weigl Measurement, Causes, and Consequences JW Goethe-University Frankfurt am Zipprich, Holger / Weigl, Paul / Lange, Bodo / Lauer, Hans-Christoph Main Department of Prosthodontics ABSTRACT- Most of two-component or multi-component implant systems use an implant-abutment connection with a clearance fit. The clinical impact is assumed as high according to the following factors:  Implant systems consisting of two or several components are much more widespread than single component systems because they offer a number of well-known clinical and technical advantages.  Unconnected crowns in the posterior region are more susceptible to technical failure of the implant-abutment interface.  Crestally or subcrestally placed implant-abutment interfaces are frequently subjected to crestal bone resorption following abutment connection. This in-vitro study examined the dynamic behavior of different designs of implant-abutment connections. Abutments were loaded at an angle of 30° with a force of up to 200 N. The distance of the point of force application from the implant platform was 8 mm; the gradation of the force was 0.3 N/ms. The interface of the implant-abutment connection was examined and measured radiologically using a professional high speed digital camera (1,000 images per second). Dr. Weigl graduated from the The results showed that, under simulated clinical conditions, complex mechanisms are responsible for the University of Munich Dental presence or absence of a micro-motion.

  3. 3. Advanced Tissue Processing (ATP): UPDATE Development of a Cleaning Process for Allograft Bone Comparison of ATP to Two Proprietary Processing Methods Tissue treated with the ATP process has been compared to allograft tissue subjected to other processing and cleaning methods from two other tissue banks: Regeneration Technologies Inc. Biocleanse® and LifeNet Allowash.® All tissue in this study was prepared into DBM based upon the Urist method.18 Biological activity was assessed in an athymic mouse model through associated ostoinductivity,12 and scored based on industry standard.14 A positive and negative control were utilized. The ATP-treated tissue demonstrated significantly higher osteoinductivity scores when compared to tissue processed at other tissue banks, 19 as seen in Figure 8. These results suggest that the higher osteoinductivity of the tissue prepared from ATP-treated bone compared to the tissue prepared from Biocleanse® and Allowash®-treated bone may result in improved incorporation of allografts treated with the ATP process.19 NEW PRODUCT: MTF PERIODERM DERMIS At MTF, we are driven by our strong Size Price Size Price commitment to safety.
