                Implantation with Simultaneous Augmentation

                Grunder, Ueli
                Procedure: - 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.

                Cell-to-Cell Communication - Inflammatory Reactions

                Stadlinger, Bernd / Terheyden, Hendrik
                Visualizing 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

                ENAMEL MATRIX DERIVATE (EMD) ON MESENCHYMAL STEM CELLS IN PERIODONTAL REGENERATION: A MICRO-TOMOGRAPHIC ANALYSIS

                Objectives: Evaluate the bone formation in periodontal fenestration defects in rats applying bone marrow mesenchymal stem cells (MSC) with or without Enamel Matrix Derivate (EMD). Methods: Periodontal fenestration defects of 2 mm in height, 4 mm in width and 1 mm in depth were created in the mandible of isogenic rats. The animals were allocated into 6 groups and further divided into 3 subgroups for euthanasia at 15, 30 or 60 days postoperative (n=6 for each subgroup). Control Group (C) was the spontaneous healing. In the Propylene Glycol Alginate Group (PGA) 25µl of the vehicle was applied in the defect. The Enamel Matrix Derivate Group (EMD) received 25 µl of Emdogain™. Mesenchymal stem cells (MSC) were collected from the iliac crest of 2 isogenic rats, isolated with Ficoll and cultured in flasks. The cells were separated by flow cytometry to obtain a cell population of CD45-90+ MSC. In the mesenchymal stem cell groups (MSC, MSC-PGA and MSC-EMD) a pellet with 1,2 x 106 cells was applied in each defect, but in MSC-PGA and MSC-EMD groups the pellet was mixed with 25µl of PGA or EMD, respectively. After euthanasia the mandibles were fixed and scanned by computed microtomography apparatus. Bone volume, bone density, trabecular number and thickness were analyzed by SigmaPlot™. The normality of data was checked and ANOVA One-Way test was used, with a significance level of 5%. Results: Bone volume was increased in all groups in all times (p 0.05). In 60 days all groups were similar and had higher volume than PGA (p 0.05) and higher than C, PGA and MSC (p 0.05). MSC-E also had higher number than C and MSC (p 0.05) but statistically larger than C, EMD and PGA (p > 0.05). In 60 days C and EMD had higher thickness than MSC, MSC-PGA and MSC-EMD (p Conclusion: The adhesion of stem cells to EMD resulted in more bone volume in periodontal regeneration defects only in the period of 30 days. However, the bone density and the trabecular number and thickness were either similar or inferior to EMD alone.

                Techniken der Sinusbodenaugmentation mit autogenem Kinnknochen

                Schultze-Mosgau, Stefan / Neukam, Friedrich Wilhelm / Basting, Gerd
                Gliederung: - Indikationsspektrum zur Sinusbodenaugmentation - Operative Technik der lateralen Sinusbodenaugmentation - Operative Technik der krestalen, endoskopisch kontrollierten Sinusbodenaugmentation - Operative Technik der autogenen Kinnknochenentnahme Im Oberkieferseitenzahnbereich kann bei einem vertikal reduzierten ortsständigen Knochenangebot von weniger als 5-7 mm vor einer kaufunktionelle Rehabilitation mit einem implantatgetragenen Zahnersatz eine Sinusbodenaugmentation zur Vergrößerung des vertikalen Knochenangebotes indiziert sein. Für eine einseitige Einlagerungsosteoplastik ist hierbei die Menge an autogenem Knochen aus der Kinnregion zumeist ausreichend. Demonstriert wird das operative Vorgehen einer einseitigen lateralen Sinusbodenaugmentation mit partikulärer Spongiosa und alternativ mit einem autogenen Blocktransplantat. Ebenfalls zeigt der Film die operative Vorgehensweise bei einer krestalen Sinusboden-augmentation mit Hilfe der endoskopisch kontrollierten Kondensationstechnik. Herausgearbeitet werden die Vor- und Nachteile der einzelnen Verfahren. Zusätzlich wird die Entnahmetechnik von Kinnknochentransplantaten an unterschiedlichen Fallbeispielen vorgestellt.
