REAL-TIME NAVIGATION: THE BEGINNING OF A NEW ERA IN GUIDED IMPLANT SURGERY
Objectives: To demonstrate that dynamic guided surgery is as predictable as conventional surgery. Methods: Partially edentulous patients requiring a fixed rehabilitation were selected for this pilot study. No specific contraindications were established, and smokers were not excluded. An impression was taken pre-operatively using an irreversible hydrocolloid (Cavex CA37®) to fabricate a diagnostic cast for moulding the surgical stent (NaviStent®). Afterwards, a standard cone-beam CT (CBCT) scan was made with the NaviStent® in place using a Planmeca Promax 3-D Max®. Images were converted into DICOM files and transformed into a 3-D virtual model using the Navident® software. The potential implant locations were planned in a prosthesis-driven way. For preparing the osteotomy, the drilling axis of the handpiece and the twist drills were calibrated. The osteotomies were prepared at low speed using a high level of cooling. The navigation software guided the drilling procedure in real time. Before installing implants, an extra calibration procedure was performed for tracking the implant. The aim of this pilot study was to determine the clinical outcome up to 12 months post-operatively for implants installed using the Navident® guided surgery system. Results: Partially edentulous men (n = 6) and women (n = 7) were included in this pilot study (mean age 52.15 years; range 20–75). Out of these 13 patients, two were current smokers of more than 10 cigarettes per day. Twenty implants were inserted. No mechanical or biological complications occurred during the surgical procedure, and no major complaints were reported, such as hemorrhage, sinus pathology or severe post-operative pain. No implants were lost up to 1 year after insertion, resulting in 100% implant survival. Conclusions: Based on the results of this pilot study, real-time navigation is a promising technique. However, there is not yet enough evidence to show that the method is as safe and predictable as conventional implant surgery. -

Implantation with Simultaneous Augmentation
Grunder, UeliProcedure: - Case evaluation - Incision technique - Implant placement - Membrane adjustment and fixation - Introduction of replacement material - Flap mobilization - Suture technique Contents: Implantation was desired for replacement of a missing upper canine tooth and the adjacent lateral incisor tooth. The initial case evaluation revealed a relatively narrow gap between these two teeth in addition to extensive hard and soft-tissue defects. We selected an incision technique that made it possible to do the augmentation work yet subsequently achieve a tension-free flap closure. Since the bony defect was large while the available space was limited, we had to go for the best possible compromise in regard to implant insertion. After the implants had been inserted, augmentation was carried out using a non-absorbable, titanium-reinforced membrane, bone replacement material, and an absorbable membrane. Extreme flap mobilization was needed to achieve flap closure. An optimal suture technique was used to complete the surgery. -
Cell-to-Cell Communication - Inflammatory Reactions
Stadlinger, Bernd / Terheyden, HendrikVisualizing the invisible while experiencing a fascination with science is the great challenge that Cell-to-Cell Communication, representing an all-new genre, has set out to meet. A spectacularly sophisticated computer animation in HD quality depicts the highly complex processes of intercellular interaction during an inflammatory periodontal reaction complete with the messenger molecules implicated. The various cell types constitute the main cast of the film, using a finely tuned communication process in their quest to destroy the bacterial invaders, with messenger molecules as supporting cast. A stunning didactic and dramatic experience! Outline: - Biofilm - Gingivitis and the Innate Immune Defense - Periodontitis and the Adaptive Immune Defense - Cleaning and Regeneration -

Lappenoperation II: Osteoplastik - Komplexe Behandlung
Mutschelknauß, R.Die Lappenmethoden wurden in der Vergangenheit wesentlich radikaler durchgeführt. Heute dient die Lappenbildung hauptsächlich dazu, die Wurzeloberfläche freizulegen, damit die Plaque und Konkremente unter Sicht entfernt werden können. Außerdem sind Korrekturen am Alveolarknochen möglich, und es können Knochentransplantate oder Regenarationsmembranen eingebracht werden. Die Lappenmethoden erstrecken sich von der offenen Kürettage bis zum vollen Schleimhautperiostlappen. Sie sind in der Regel an den Seitenzähnen bei Sondierungstiefen über 5 Millimeter, vertikalen Knocheneinbrüchen und Furkationsbefall indiziert. Die außer zum Scaling und Wurzelglätten notwendigen Instrumente werden in ihrer Wirkungsweise einzeln gezeigt. Gliederung: - Historische Entwicklung ab 1963 - Indikationen zur Lappenoperation - Instrumentarium für operative Freilegung sowie Küretten, Feilen, Fräsen und Diamanten - Schleimhautperiostlappen - Rezidivoperation - Komplexe Behandlung mit semipermanenter Schienung, Lappenoperation mit Osteoplastiken und Interimsversorgung - Langzeitergebnisse nach 4 Monaten und 3 Jahren. -

Techniken des plastischen Verschlusses einer Mund-Antrum-Verbindung
Schultze-Mosgau, Stefan / Neukam, Friedrich Wilhelm / Basting, GerdGliederung: - Gliederung einer Mund-Antrum-Verbindung - Ausschluss von entzündlichen, zystischen oder tumorösen Kieferhöhlenerkrankungen - Wangenlappenplastik zur plastischen Deckung einer Mund-Antrum-Verbindung, Demonstration der Brückenlappenplastik - Demonstration der Brückenlappenplastik - Demonstration der Palatinallappenplastik - Postoperative Verhaltensmaßnahmen. Bei weit in den Oberkieferalveolarfortsatz reichenden Recessus der Kieferhöhle kann es bei Extraktion von Oberkieferseitenzähnen zur Eröffnung der Kieferhöhle kommen. Die Feststellung einer einer Mund-Antrum-Verbindung erfolgt durch einen Nasenblasversuch oder die Sondierung der Alveole mit stumpfen Sonden. Nach Ausschluss einer entzünd-lichen, zystischen oder tumorösen Kieferhöhlenerkrankung sollte eine Mund-Antrum-Verbindung unverzüglich innerhalb der nächsten 24 Stunden nach Extraktion plastisch verschlossen werden, um eine Kontamination der keimfreien Kieferhöhle zu verhindern. Demonstriert wird die plastische Deckung durch eine vestibulär gestielte Wangen-lappenplastik. Nach Bildung eines vestibulär gestielten Mukoperiolastlappens wird der Lappen durch eine Schlitzung des Periostes so verlängert, dass ein spannungsfreier Verschluss der eröffneten Kieferhöhle möglich wird, ohne gleichzeitig die Durchblutung des Lappens zu gefährden.

Hand-over of presidency in Zurich
On the occasion of the Osteology Board Meeting on June 22, 2015 in Zurich, the presidency of the Osteology Foundation was officially handed over from Christoph Hmmerle to Mariano Sanz. Professor Christoph Hmmerle served as president of the Osteology Foundation for 12 years, ever since it was established. Looking back at his term of office, he said in an interview prior to the meeting in Zurich: The Osteology Foundation has grown to be a highly respectable organization over recent years. I think the key elements for this success have been the excellent teamwork among the members of the Foundation Board, the dedication of those working in the office and, very importantly, the support and the academic freedom granted by the Founder. Read the full interview with Christoph Hmmerle Even though his term of office as president of the Osteology Foundation has ended, Christoph Hmmerle will remain a member of the Board for two more years, contributing to the development of the Foundation and its activities with his great experience and knowledge. Professor Mariano Sanz, who in Zurich officially took over as new president of the Osteology Foundation, has been a member of the Board for 12 years, he also served as Chairmen of the Education Committee and Member of the Executive Board for several years. For him, the Foundation and its activities are therefore already familiar - with Mariano Sanz, the Osteology Foundation is in the best hands, said Christoph Hmmerle. Mariano Sanz thanked him, and said that in the past 12 years Christoph Hmmerle has done a superb job. Not only as a result of his vision and work, but also through his personal and social skills has the Foundation become a friendly family of leaders all striving for the same objective, which is to fulfil the mission of the Osteology Foundation. Mariano Sanz does not intend to change the strategy of the Osteology Foundation. We will continue the successful work, and wherever possible extend it to other parts of the world, he said in an interview, and added: we shall consolidate our accomplishments, but at the same time open up to new technologies and improve communications media with the goal of widening our reach in order to better fulfil our mission.

Clinical and radiografic evaluation with 5 years follow-up of two dental implant-supported mandibular overdentures in the patient receiving oral bisphosphonate therapy
Objectives: Systemic diseases may affect oral tissues by increasing their susceptibility to other diseases or by interfering with healing. Oral bisphosphonates (BP) are commonly prescribed for patients with osteoporosis to arrest bone loss and preserve bone density. The American Association of Oral and Maxillofacial Surgeons (AAOMS) have suggested a cautious approach to implant surgery and extractions for patients receiving bisphosphonate therapy. Methods: Two dental implants (NucleOSS, TR) were inserted in the mandible of a 78-year-old female. The patient has been taking oral alendronate (Fosamax®, marketed by Merck) as a treatment of postmenopausal osteoporosis disease, during the last 3 years. The dose of the bisphosphonate was one tablet of 70 mg once a week. Results: Dental implants in the patient was successful with uneventful healing. There is was no differences between baseline and 5-year Examinations at Recall in PPD, BOP, Mobility, and bone loss. Conclusion: History of oral BP use is not an absolute contraindication for dental implant placement and dental implants can be osseointegrated successfully in this patient population. Great attention should be paid to the regular dental recall for implant-prosthetic restorations. -
