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. -
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 -

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. -
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. -

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. -

Restauration mit Komposit-Schichttechnik im Frontzahnbereich/OK
Dietschi, DidierMorphologische Missbildungen wie zapfenförmige Seitenzähne sind häufige Anomalien, die restaurativ zu behandeln sind. Mit minimalinvasiven dentalchirurgischen Techniken, die zunehmend an Popularität in der ästhetischen Zahnmedizin gewinnen, ist eine idealästhetische Korrektur weitgehend oder gänzlich ohne Gewebsverlust möglich. Dieses Video zeigt die Rekonstruktion von zwei lateralen Schneidezähnen mit direktem Kompositaufbau gefolgt von einer sogenannten "natürlichen Beschichtung" mit Applikation von einzelnen Dentin- und Schmelzschichten, um die natürliche Zahnanatomie nachzuahmen. Alle Schritte zur Wiederherstellung des Zahns werden bis ins Detail erklärt, inklusive Farbauswahl, Anlegen des Kofferdamms, Klebeverfahren sowie Finishing und Polishing der Dentin- und Schmelzschichten. Durch die Einhaltung einer präzisen und sorgfältigen Operationstechnik erzielt man ein zuverlässiges Ergebnis mit einem völlig natürlich aussehenden Zahnersatz. -

Statistical Analysis
based on the book chapter by Jrg Hsler Summary This chapter will enable clinical investigators to select statistical methods that extract results and conclusions from quantitative data which are both meaningful and can be compared with findings of other studies. Among the key issues discussed are the need to develop a data analysis plan, to engage a biostatistician early in the design process, and to conduct a power analysis to determine how many participants should be recruited and how many to include in treatment and control groups. There are explanations of different types of randomization processes (simple, stratified, balanced or computer-generated), error probabilities and error corrections, data distribution, and rejection of the null hypothesis on the basis of a statistical test decision. The authors explain how to choose suitable endpoints and analytical tools for specific clinical scenarios that relate to the study hypothesis. The role of descriptive measures, statistical estimates and graphs is made clear, including the concepts of confidence intervals, means, medians and standard deviations. They also describe how statistical models such as analysis of variance (ANOVA) are used to explore relations between variables, and one-way and two-way tests are used to explore relations between impact factors. The role of multiple testing is clarified, and the use of Tukey and Bonferroni corrections, Newman--Keulbs, Scehhe and Dunn devices, and Fishers least significant device (LSD) in error correction.
