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. -

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 -

Anterior Implant Placement using in a Combined Roll Flap and Connective Tissue Graft Technique
Schultze-Mosgau, StefanProcedure: - Incision Technique and Roll Flap Creation - Excision and Transplantation of Connective Tissue Graft Material from the Palate - Implant Placement and Fixation Procedure Contents: This video describes the preparation of an implant insertion site for placement of an individual implant at site 11 using a roll flap and free connective tissue graft technique. The procedure is designed to shape the implant insertion site and to create a secure, keratinized gingival base. Step-by-step, the operator demonstrates the incision technique, the roll flap creation procedure and the techniques used for excision, transplantation and fixation of the free connective tissue graft within the scope of implant placement. -

EFFECTS OF PLATELET-RICH PLASMA (PRP) PRODUCTS ON VIABILITY AND PROLIFERATION RATE OF HUMAN GINGIVAL FIBROBLASTS (HGF)
Objectives: Platelet preparations are increasingly used to improve bone and soft tissue regeneration, but basic studies are insufficient for supporting the real efficacies of these products. Controversy exists about the effects of platelet product on hard and soft tissue regeneration, therefore more in vitro studies are needed. The aim of this investigation was to compare the in vitro effects of platelet-rich growth factor (PRGF) and platelet-rich fibrin (PRF) on the proliferation of human gingival fibroblasts (HGF). Methods: Whole blood samples were collected from a healthy volunteer. Anitua's PRGF and Choukran's PRF were prepared according to standard protocols. After culture periods of 24, 48 and 72 hours, HGF cell proliferation was evaluated by MTT assay. Statistical analysis was performed using one-way ANOVA followed by Tukey-Kramer’s multiple comparisons and p values less than 0.001 were considered significant. Results: The optical density of the negative control (fetal bovine serum (FBS) 1%) was set at 100% and other groups were expressed as a percentage of this. Our results showed PRGF treatment induced statistically significant (p 1.73%, p Conclusion: PRGF has a strong stimulant effect on HGF cell viability and proliferation compared to PRF. Further comparative studies of PRF and PRGF are needed using more cell lines and primary cells with different in vitro proliferation assays and more in vivo assays.
