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. -
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. -
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 -

POLYSACCHARIDE NANOGEL CROSS-LINKED MEMBRANE FOR GUIDED BONE REGENERATION (GBR)
Takayuki Miyahara (Japan), Christer Dahlin, Anders Palmquist, Asako Shimoda, Myat Nyan, Yoshihide Hashimoto, Kazunari Akiyoshi, Shohei Kasugai Objectives: GBR is a bone augmentation technique that uses a barrier membrane to create a secluded space for unimpeded bone formation. In a previous report, a wet membrane of polysaccharide nanogel cross-linked (NanoClikä/®) hydrogel was successfully evaluated. The drawbacks of the material are shortshelf-life and difficulties in clinical handling. The purpose of this study was to evaluate the biological outcome of polysaccharide NanoClikä membrane for GBR. Methods: Bilateral symmetrical full-thickness parietal bone defects of 5-mm diameter were created using a bone trephine bur in 16 adult Wistar rats. Each defect was covered with a collagen membrane, a wet or dry NanoClikä membrane, or no membrane (control). The animals were sacrificed at 4 weeks and assessed using micro-CT and histology. Results: New bone formation in terms of bone volume in the bone defect was higher for both membrane groups compared to both control and collagen groups. There was no significant difference between the wet and dry membranes. Notably, the newly formed bone in the defect in both wet and dry groups was uniform and histologically indistinguishable from the original bone, but in the collagen group the new bone showed an irregular structure that was morphologically different from original bone. Conclusions: The dry NanoClik membrane stimulated bone regeneration to the same level as the wet membrane. -

USE OF 3-D COLLAGEN MATRIX (MUCOGRAFT) IN SURGICAL MANAGEMENT OF ORO-ANTRAL COMMUNICATION (OAC) AND ITS COMPARISON TO OTHER MODALITIES
Objectives: Oro-antral communications (OAC) can occur after extraction of teeth in the maxilla. Several closure techniques can be used to treat the complication, including conservative flapless techniques. The aim of this study was to compare different techniques for closure of OAC and evaluate their efficiencies. Methods: Ninety-five patients with OAC were divided into five groups of 15 patients for treatment with: a flapless technique with Mucograft Sealä/®, a flapless technique with collagen in root design, a Wasmundä/® buccal flap, free-flap from palate, and a sandwich technique (collagen–Bio-Ossä/®-collagen-free gingival graft). In the first 2 weeks after intervention, patients recorded their perceptions of bleeding, swelling, pain and bruising on a visual analogue scale (VAS). Post-surgical complications were assessed clinically at 1 week, 2 weeks, 1 month and 6 months post-surgery. Results: Closure of all wounds was achieved from 2 weeks to 1 month. There were no post-surgical complications. All VAS parameters decreased to almost zero by day 14 and were maintained after 6 months. Scores for swelling and bruising peaked on days 2 and 3, respectively, before decreasing. Conclusions: Using a flap or flapless technique depends on personal choice and skills of the surgeon. The use of Mucograftä/® for closure of OAC is effective and safe, and is associated with low morbidity and no post-surgical complications.
