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 -

Aesthetic upper anterior implant placement case
Dr. Dominik BüchiDr. Dominik Büchi performed a ridge preservation to keep the soft tissue volume. He then placed an implant 8 weeks later with simultaneous GBR. The final emergence profile was created by a fixed provisional crown. -
Soft Tissue Management in the Aesthetic Zone
Daniel ThomaExpert presenter PD Dr. Daniel Thoma is a Head of Academic Unit at the Clinic for Fixed and Removable Prosthodontics and Dental Material Sciences, University of Zurich, Switzerland. Long-term successful outcomes with implant therapy are based on a number of parameters. Among these, the critical assessment of the peri-implant soft tissues and subsequent therapeutical interventions are considered key factors. -

Minimalinvasive Implantatchirurgie auf Basis dreidimensionaler CT-Planung bei einer systematischen Gesamtrehabilitation
Beck, FrankGliederung: - Schnittechnik 36, 44 - Schonende Lappenmobilisation - Pilotbohrung mit CT-Schablone - Sequentielles Aufbereiten und Implantieren - Knochenentnahme und Augmentation - Wundverschluss Inhalt: Die systematische Gesamtrehabilitation stellt eine große Herausforderung dar, insbesondere bei Vorliegen einer parodontalen Erkrankung und Verlust von Stützzonen. Es muss eine präziser Therapieplan erarbeitet werden. Nach den konservativen Vorbehandlungen erfolgt die Therapie der Parodontitis. Erst nach Abheilung ist eine Beurteilung der zu erwartenden Weichgewebsästhetik möglich. Zur Ergänzung verlorengegangener Stützzonen im atrophischen Unterkiefer mittels enossalen Implantaten wird eine dreidimensionale Analyse zum navigierten Implantieren durchgeführt. Am Ende der Abheilphasen nach parodontaler und implantologischer Therapie sind ca. 6 Monate vergangen. Erst jetzt kann die prothetische Rekonstruktion erfolgen.

Ethical Considerations for Performing Research in Animals
Laboratory tests have limited value for assessing the safety and effectiveness of new therapies in people. Tests must also be conducted on animals that resemble humans, both biologically and developmentally. We generally acknowledge that certain animals may be caught and sold, kept in captivity, or eaten, but using animals to meet human needs is as an area of huge controversy. This chapter gives a broad perspective on the ethical basis for animal experiments, drawing from the modern “common sense” view and several longstanding philosophical theories. Moral status is considered, alongside integrity, autonomy and dignity of animals, and their ability to reason, to form memories, and to experience pleasure or pain. Smaller animals, such as mice, rats and rabbits are essential for proving a basic principle or concept. Larger animals, such as goats, pigs, sheep, dogs and monkeys, are used more sparingly, not least because of the costs involved in their care; they are necessary because of their greater similarity to humans and thus are more relevant to advancing clinical practice. However, conflicts of interest tend to be larger with animals that are more similar to humans. Primate and dogs tend to evoke our compassion more strongly than rodents or animals we commonly eat. The authors provoke thought on this subject through examples in which the interests of humans are weighed up with those of animals in studies of cosmetics, childhood leukemia and dental defects. -

Minimally Invasive Treatment of Periodontitis (Surgical Treatment of Recurrences)
Beck, FrankContents: When treating recurrent periodontitis surgically, the challenge is to sacrifice as little soft tissue as possible in esthetically critical areas. This surgical case demonstrates the technique used in patients with narrow approximal spaces.
