    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.

    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

    Covering a Recession with a Soft Tissue Transplant

    Heinz, Bernd / Jepsen, Sören
    Objectives: Use of a soft tissue graft for recession coverage at tooth 23 and for gingival augmentation. Content: 1. Incision around tooth 23, intra-sulcular preparation, mobilization of coronal sliding flap, and pre-flap preparation. 2. Root smoothing, reduction of ground cavity with diamond burs from Perioset system. 3. Preparation and harvesting of connective tissue flap from palate, Emdogain application, and wound closure. 4. Placement of interrupted interdental sutures for fixation of connective tissue flap.

    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.

    Aesthetic upper anterior implant placement case

    Dr. Dominik Büchi
    Dr. 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 Thoma
    Expert 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.

    Schneidekantenaufbau mit Reparatur an Zahn 11

    Frankenberger, Roland
    Gliederung: - Darstellung des Defekts und Problematik der Reparatur - Sandstrahlen und adhäsive Vorbehandlung - Biomimetische Schichtung mit Schmelz- und Dentinmassen - Ausarbeiten, Herstellen des Halo-Effekts, Politur Inhalt: Schneidekantenfraktur an einem vielfach gefullten Zahn 11. Da die zervikale Frakturflache aus dem Kompositanteil einer darunterliegenden Black-III-Kavitat liegt, hatte man fruher diese vollig intakte Fullung wohl mitentfernt. Heute ist es unter strenger Einhaltung minimal-invasiver Kautelen moglich, diese Situation als Reparatur zu sehen und die angrenzende Kompositrestauration zu belassen. Da diese Fullung seit 10 Jahren intakt ist, ware mit einer Komplettentfernung auch mit Lupenbrille eine Vergroserung des Defekts wahrscheinlich. Deshalb erfolgt die Vorbehandlung zuerst mit einem intraoralen Sandstrahlgerat (Micro-Etcher mit 27 µm Al2O3-Pulver) in Richtung Komposit, und erst danach die konventionelle Konditionierung der Zahnhartsubstanzen Schmelz und Dentin mit Phosphorsaure. Das Bonding wird dann inclusive Dentinadhasiv auf Schmelz, Dentin und gealtertem Komposit durchgefuhrt. Diese Methode ist bereits in der Literatur beschrieben (Frankenberger et al., Am J Dent 2003). Die Rekonstruktion erfolgt dann mit Schmelz- und Dentinmasse eines asthetischen Komposits unter Zuhilfenahme eines Silikonschlussels von palatinal. Dadurch ist es moglich, diese Restauration biomimetisch und naturgetreu inclusive des inzisalen Halo-Effekts herzustellen. Abschlussfoto: Nachster Recall.
