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. -

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. -

Research Design and Biostatistical Considerations
The findings of studies are of little value without proper statistical analyses that reveal the power of the results, and separate them from events that occur simply by chance. Robust analysis also allows patterns to be observed and comparisons to be made with similar studies. However, the field of statistics can be confusing and overwhelming. This chapter provides an easily understandable summary of the key principles and parameters involved, and the aims of different statistical tests. The describes real preclinical studies on bone regeneration to illustrate concepts such as variance and skew, probability, distribution, standard deviations, and categorical and non-independent data. It also gives guidance on the importance of sample size, replication and specific methods like split-mouth designs. The main focus is on an efficient top–down approach, whereby statistical analysis starts before the study begins, and sometimes involves obtaining the advice of a qualified statistician. The role of generating explicit and biologically valid questions or hypotheses is highlighted, and the need to determine adequate sample sizes and control conditions, with suitable endpoints and collection of only relevant data. Planning the analytical approach in this way produces clinically applicable results and allows meaningful conclusions to be drawn within and across studies. As such, getting the statistics right is essential for translating laboratory findings into clinical practice. -
REHABILITATION OF A PATIENT WITH NOSE MUTILATION RESULTING FROM CARCINOLOGIC SURGERY USING EXTRAORAL FIXTURES AND EPITHESIS
Objectives: Treatment of nose mutilation resulting from cancer treatment requires use of a technique that allows good aesthetic rehabilitation. Plastic surgery is an option, but involves several surgeries, which are time consuming and often have only partial aesthetic results. Using an extraoral fixture for bone anchorage of a removable nose prosthesis results in quicker and better aesthetic results. Methods: We present the case of a 60-year-old man who had undergone a total nasal resection for a large basal cell carcinoma of the nose. Anatomopathologic analysis of the resection showed free margins, and did not reveal any ganglionic metastasis. No radiotherapy was applied. One year later, two extraoral fixtures were inserted in the frontonasal bone, under general anaesthesia, and 4 months after insertion, the fixtures were denudated under local anaesthesia, and prosthetic abutments placed. After 2 weeks, prosthetic steps were realised, and the patient received a removable nasal prosthesis that was fixed by two magnetic devices on the implants. This report describes and illustrates the various surgical and prosthetic steps involved. Results: Patient satisfaction was achieved with this technique. Surgical reconstruction following a centrofacial mutilation is challenging because of the need to recreate a complex 3-D nasal form. Extraoral craniofacial fixtures have an average success rate of 95% in non-irradiated patients and have made it possible for the nasal epithesis to be considered as a forerunner in cosmetic rehabilitation strategies. Conclusions: The clinical case presented here shows that transcutaneous extraoral fixtures may be used as bone anchorage for nasal epitheses, in cases of nasal mutilation resulting from cancer treatment.
