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.

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

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
