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.

In this webinar moderated by Prof Ronald Jung and Dr. Adrián Guerrero the expert presenters Prof. Christoph Hämmerle and Dr. José Nart discuss about the importance and benefits of using short and narrow implants.

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.

Content: - Periodontal maintenance therapy for teeth 34 and 35, including the regeneration of a bone defect using bone replacement material, collagen membrane and sutures. - Curettage for treatment of periodontal pockets. - Treatment of gingival pressure sores caused by tight-fitting orthodontic apparatus. - Incision of buccal attachment to relieve gingival pressure for elimination of gingival recession.

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.

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.

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.

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.

Gliederung: - Sondierung - Inzision und Mobilisation des Lappens - Präparation des palatinalen Lappens mit Erhaltung des interdentalen Gewebes - Detoxifikation und Konkremententfernung an 11 - Abtragen autogener Knochenspäne aus der spina nasalis - Konditionieren der Wurzeloberfläche mit EDTA-Gel - Applikation von Emdogain und Auffüllen des Knochendefektes - Wundverschluss Inhalt Nach Abschluss der Initialtherapie einer agressiven Parodontitis wird versucht, regenerativ an Zahn 11 eine trichterförmige Tasche zu therapieren. Der Dreh- und Engstand des Zahnes mit seiner Inklination nach bukkal stellte einen begünstigenden äthiologischen Faktor dar. Der kausale Ansatz, diesen Faktor nach Abschluss der Therapie durch eine kieferorthopädische Einordnung des Zahnes zu beseitigen, war von der Patientin nicht gewünscht worden. Folglich limitiert sich die Therapie auf den chirurgischen Regenerationsversuch. Der interdentale Abstand war größer als 3 mm, die Knochentasche weitgehend dreiwandig, so dass die Erfolgschancen als günstig beurteilt werden konnten. Zunächst wird durch das Sounding der Verlauf der Knochenkante definiert. Die exakte Kenntnis der Knochenanatomie in allen drei Dimensionen ist für eine Planung der Inzision unerlässlich. Es wird deutlich, dass es sich um einen knochenbegrenzten trichterförmigen Defekt regio 11 mit guten Chancen auf eine Regeneration handelt. Eine wesentliche Schwierigkeit bei diesem Eingriff besteht in der Notwendigkeit, den Defekt während der Heilung komplett mit Weichgewebe bedeckt zu halten. Dazu wird die ?Papilla Preservation Technique? nach Cortellini angewandt. Nach der Inzision und der Mobilisation der Lappen wird deutlich, dass der Defekt im koronalen Bereich 2-wandig ist. Bukkal fehlt Knochen. Nach der vorliegenden Datenlage in der Literatur ist eine Regeneration mit einem Schmelzmatrixprotein (Emdogain®) alleine in punkto Attachmentgewinn genauso erfolgreich, wie Verfahren, die auf eine Kombination aus Knochentransplantaten und Emdogain setzen. Dennoch wird im vorliegenden Fall eine Kombinationstechnik eingesetzt von der man sich eine bessere Stützung der Papille versprechen kann.In dem vorliegenden Fall werden autogene Knochenspäne aus der Spina Nasalis eingesetzt, die leicht aus dem gleichen Situs mit der Piezotechnik gewonnen werden können. Nach schonender Detoxifikation der Wurzeloberfläche wird diese mit Emdogain behandelt, der Defekt mit autogenen Knochenspänen aufgefüllt und mit mikrochirurgischen Nahttechniken verschlossen. Das Ergebnis nach 6 Monaten mit einer teilweisen Regeneration der Papille wird gezeigt.
