Bone ring technique significantly reduces treatment time for implant patients

02.06.2010 | Vertical augmentation and implant placement in just one procedure

A theory course with an exclusive expert interview on May 28, 2010, in Frankfurt am Main gave dentists practicing surgery, maxillofacial surgeons and representatives of selected professional media the opportunity to experience step-by-step an innovative augmentation technique presented by implantologists Dr. Bernhard Giesenhagen and Dr. Orcan Yüksel. Their bone ring technique makes it possible to use precisely fitted bone ring transplants to perform the three-dimensional vertical augmentation of bone defects and the implant placement in one single session. In comparison with the classical bone block augmentation, this reduces the patient’s treatment time by approximately five months.

The use of autogenous bone is often unavoidable for correcting three-dimensional bone defects. Implantologist Dr. Bernhard Giesenhagen, Melsungen, started using autogenous bone rings for augmentation of three-dimensional bone defects and placing implants at the same procedure six years ago. The recipient site and the bone ring are prepared to fit precisely together with round trephine drills (Helmut Zepf GmbH). Long-term observation of approximately 900 augmentations confirms that the bone ring technique has a success rate greater than 98 percent.

A decisive factor for the success of the technique is the use of an implant system that fixes the transplant immobily in the recipient site. According to Dr. Giesenhagen the ANKYLOS system supplied by DENTSPLY Friadent meets all the requirements for an implant system for the bone ring technique. The macro and microdesign of the ANKYLOS implant with its growth-activating Friadent plus surface, the system-immanent platform-switching and the tissue-stabilizing connection establishes the required conditions for application of the bone ring technique. Its specific suitability for the technique can be attributed to the parallel-walled implant design without a thread in the area of the implant neck and the progressive thread geometry in the apical region. The micromovement-free and bacteria-proof connection of ANKYLOS is also important, because it enables subcrestal placement. If necessary, the bone ring can be fixed in place with a selection membrane screws available in the product range.

Dr. Giesenhagen, along with his colleague Dr. Yüksel, also an implantologist, offers continuing clinical courses in the bone ring technique. "We enjoy passing on our knowledge of the bone ring technique to interested practitioners. The technique has been designed to save the patient an additional procedure and treatment time,“ explained Giesenhagen. Dentists practicing surgery and maxillofacial surgeons can acquaint themselves with the potential of this unique augmentation technique in live surgeries and hands-on courses. Courses will be available in September, October and November this year in Frankfurt am Main or Melsungen, Germany.
