Covering a Recession with a Soft Tissue Transplant
Heinz, Bernd / Jepsen, SörenObjectives: 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. -
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. -

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 -

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. -

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. -

Regenerative Behandlung multipler Rezessionen
Heinz, BerndGliederung - Befund - Schnittführung - Wurzelglättung - Applikation von PrefGel - Applikation von Emdogain - Periostschlitzung - Nahttechnik Inhalt: Regenerative Parodontalchirurgie mit dem Schmelz-Matrix-Protein Emdogain: Ziel der regenerativen Parodontalchirurgie ist der Wiederaufbau zerstörter parodontaler Strukturen. Eingesetzt wurden bislang und werden nach wie vor Knochentransplantate, Knochenersatzmaterialien sowie nicht resorbierbare und resorbierbare Membranen. Ein neuerer therapeutischer Ansatz zur parodontalen Regeneration ist die Wurzeloberflächenkonditionierung mit dem Schmelz-Matrix-Protein Emdogain (Biora, Schweden). Durch den Proteinkomplex wird die Neubildung von Wurzelzement stimuliert, was wiederum die Neubildung von Knochen und Kollagenfasern zur Folge hat. Zu diesem Verfahren und seiner Wirkungsweise wurden seit Anfang 1980 umfangreiche Untersuchungen und Studien von einem schwedischen Forscherteam um Prof. Lars Hammerström durchgeführt. Mittlerweile wird das Schmelz-Matrix-Protein Emdogain zur Behandlung von vertikalen Knochendefekten und von Furkationserkrankungen eingesetzt. Die freigelegte Wurzeloberfläche wird zunächst sorgfältig mit Handinstrumenten oder rotierenden feinkörnigen Diamanten gescalet. Sodann wird die EDTA-Suspension Pref-Gel (Biora, Schweden) aufgetragen und nach zwei Minuten mit physiologischer Kochsalzlösung gründlich abgespült. Die EDTA-Suspension bewirkt die Entfernung des Smearlayers und öffnet die Dentintubuli, wodurch eine bessere Verbindung von Emdogain an die Wurzeloberfläche erreicht wird. Sofort anschließend wird Emdogain auf die blut- und speichelfreie Wurzeloberfläche appliziert. Danach erfolgt der Nahtverschluss. -

Flap designs for Interdental Tissue Preservation in Periodontal Therapy
Salvi, Giovanni E.Procedure: - Introduction: History -Taking, Examination, Diagnosis, Etiology, Prognosis for Individual Teeth - Four - Phase Treatment Sequence - Modified Papilla Preservation Technique(MPPT) - Simplified Papilla Preservation Technique (SPPT) - Findings 6 months after Surgery Synopsis The Modified and Simplified Papilla Preservation Techniques for conservation of interproximal papillary tissue were designed to provide access to deep and narrow bony defects to enable regenerative periodontal treatment. The Modified Papilla Preservation Technique (MPPT) was designed to ensure tension-free primary closure via barrier membranes in patients with small interdental spaces. The Simplified Papilla Preservation Technique(SPPT) is used to gain access to narrow interdental spaces ( < 2mm) and to deep defects in the lateral tooth region. Apart from preserving primary wound closure in the interdental space, the two techniques also serve to keep the membrane from collapsing into the bony defect. Both MPPT and SPPT employ special suture techniques to ensure tension-free primary closure of the interdental space. This video clip also serves to demonstrate that the two techniques of interproximal tissue preservation can also be used for periodontal interventions without regenerative measures. -

Bone Transfer
Streckbein, RolandContent: Description of system and instruments. The patient had a considerable bone deficit at tooth 21. Augmentation was therefore required and was carried out using calibrated instruments. The augmentation site was prepared using instruments that matched the tools used to harvest the cylindrical bone graft at the donor site. This perfect match between the augmentation region and the bone transplant accelerated osseointegration, there by shortening the required waiting time for implant placement.
