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. -
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. -
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. -

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. -

COX INHIBITORS SUPPRESS THE DIFFERENTIATION OF HUMAN OSTEOSARCOMA CELLS
Objectives: Recent reports of impaired bone healing associated with non-steroidal anti-inflammatory drugs (NSAIDs) have raised major concerns. This study was aimed to evaluate the effect of COX inhibitors in osteoblastic differentiation of osteoblast-like human osteosarcoma (HOS) cells and to evaluate whether selective COX-1 and COX-2 inhibitors have different effects on osteoblastic differentiation using HOS cells. Methods: HOS cells were cultured with selective COX-1 inhibitors (SC-560) and selective COX-2 inhibitors (NS-398). Cell numbers were counted and cell activity was measured using a WST-1 assay for 5 days of culture. Expression of alkaline phosphatase (ALP), bone morphogenetic protein (BMP)-2, bone sialoprotein (BSP) and osteocalcin (OCN) mRNA was evaluated by reverse transcriptase polymerase chain reaction (RT-PCR). Osteoblastic differentiation in cell cultures was also characterised by ALP activity. Results: SC-560 and NS-398 treatment did not inhibit cell activity below the concentration of 50nM and 1μM, respectively. Gene expression of BMP-2, BSP and OCN was not changed when HOS cells were treated with SC-560, whereas ALP mRNA expression was decreased when treated with 50nM and 100nM SC-560. ALP, BMP-2 and BSP gene expression was not changed in the HOS cells treated with NS-398, whereas OCN gene expression was prominently decreased when treated with NS-398 above concentrations of 100nM. A decrease in ALP activity after 5 days of culture was observed in SC-560- and NS-398-treated cells. Conclusions: These results suggest that COX inhibitors at higher concentrations suppress the osteoblastic differentiation of HOS cells and downregulate osteoblast-related genes. The mechanism of action of selective COX-2 inhibitors also differs from that of COX-1 inhibitors. The long-term use of high-dose NSAIDs for the control of pain and inflammation after dental surgery could have a negative effect on bone healing and on the outcome of bone management. -
