    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.

    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.

    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.

    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

    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.

    Sinus Floor Augmentation with Autogenous Chin Bone Grafts

    Schultze-Mosgau, Stefan / Neukam, Friedrich Wilhelm / Basting, Gerd
    Content: In the maxillary incisor region, a sinus floor augmentation to enlarge the vertical bone supply may be indicated for a vertically reduced local bone height of less than 5 to 7 mm before procedures to rehabilitate masticatory function with an implant-bearing tooth replacement. For a single-sided deposit osteoplasty, the quantity of autogenous bone from the chin region is usually sufficient. The operative procedure of a single-sided lateral sinus floor augmentation is demonstrated with particulate spongious bone and alternatively with an autogenous block graft. The video also shows the operative method for a crestal sinus floor augmentation with the aid of the endoscopically controlled condensation technique. The advantages and disadvantages of the individual procedures are highlighted. In addition, the technique for harvesting chin bone transplants in different case examples is shown. Outline: - Operative technique for lateral sinus floor augmentation with autogenous particulate spongious bone - Operative technique for lateral sinus floor augmentation with autogenous block grafts - Crestal, endoscopically controlled sinus floor augmentation with condensation technique - Techniques for harvesting chin bone grafts - Range of indication for sinus floor augmentation - Lateral sinus floor augmentation - Operative technique of crestal, endoscopically controlled sinus floor augmentation - Operative technique of autogenous chin bone removal
