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 -

Methoden der Lappengestaltung zur Gewebeerhaltung im Rahmen der Parodontaltherapie
Salvi, Giovanni E.Gliederung: - Einleitung: Anamnese, Befundaufnahme, Diagnose, Ätiologie, Einzelzahnprognose - Behandlungsablauf in 4 Phasen - Modifizierte Papillenerhaltungstechnik (MPPT) - Vereinfachte Papillenerhaltungstechnik (SPPT) - Befundaufnahme 6 Monate postoperativ Die modifizierte (MPPT) und die vereinfachte (SPPT) Lappengestaltung zur Erhaltung des interproximalen Papillengewebes wurden entwickelt, um Zugang zu tiefen und engen Knochendefekten bei regenerativen Verfahren zu schaffen. Die modifizierte Technik zur Papillenerhaltung (MPPT) wurde entwickelt, um bei Interdentalräumen mit einer Breite von größer / gleich 2mm die Aufrechterhaltung des spannungsfreien Primärverschlusses über Barrieremembranen zu gewährleisten. Um auch in engen Zwischenräumen ( < 2mm) und im Seitenzahnbereich Zugang zu tiefen Defekten zu schaffen, wurde die vereinfachte (SPPT) Lappengestaltung entwickelt. Zusätzlich zur Erhaltung des primären Wundverschlusses im Interdentalraum, bezwecken beide Techniken eine Verhinderung des Membrankollapses in den Knochendefekt. Spezielle Nahttechniken erlauben es bei beiden Verfahren, einen primären und spannungsfreien Wundverschluss des Interdentalraumes zu erzielen. Das Ziel dieser Videoaufzeichnung ist es, auch bei parodontalchirurgischen Eingriffen ohne Anwendung regenerativer Maßnahmen, beide Techniken zur interproximalen Gewebserhaltung darzustellen. -

APPLICATION OF DENTAL IMPLANT TREATMENT FOR AESTHETIC AND FUNCTIONAL REHABILITATION OF ALVEOLAR CLEFT PATIENTS
Objectives: Patients with cleft lip and palate (CLP) frequently have a missing incisor at the alveolar cleft site. Owing to recent advances in secondary bone grafting (SBG) techniques, dental implant treatment has become an acceptable method for restoring the edentulous space at the cleft site in addition to conventional methods using bridges or dentures. In this study, we investigated the risk factors related to aesthetic outcomes of implant treatment at alveolar cleft sites. Methods: We examined a total of 13 patients (8 women, 5 men) treated with implants for missing teeth associated with an alveolar cleft at the Implant Clinic of the Dental Hospital at Tokyo Medical and Dental University between 2002 and 2010. The patients’ genders, cleft types and number of dental implants were recorded, as well as their ages at bone grafting for cleft closure, additional bone grafting prior to dental implant surgery, and dental implant placement. Three patients had a bilateral and ten had a unilateral cleft lip, alveolus and palate. Sixteen dental implants were evaluated. Risk factors such as lip line, length from the nasal floor to the alveolar ridge, width of the edentulous span, gingival margin of the adjacent teeth, and cleft types (bilateral or unilateral) were evaluated, and designated as either high risk or low risk. Results: Neither dental implant loss nor bone resorption around the dental implants were observed within 5 to 13 years after final restoration. All patients were satisfied with the aesthetic and functional outcomes, and all but one underwent bone grafting to close the alveolar cleft with autologous cancellous bone harvested from the iliac crest (SBG) between the ages of 11 and 28 years. Two underwent additional bone grafting before implant placement. The patients were 18–36 years old (mean 23) at the time of placement. In 11 patients, dental implants were installed at least 6 months after the last bone graft at the cleft sites. One patient did not undergo bone grafting before implant surgery, and one had an implant installed five months after the last bone grafting. Two cases with only low risk factors had good aesthetic outcomes of implant treatment. Out of the remainder, eight had one high-risk factor, one had three high-risk factors, and two cases had four high-risk factors at the time of placement. Aesthetic outcomes of the one high-risk factor group were slightly inferior to the no high-risk factor group, but they were still satisfactory. The value of aesthetic outcomes did not vary among the different types of risk factors; in contrast, aesthetic outcomes of the three and four high-risk factor groups were inferior to those of other groups. Conclusion: The time period between last bone graft at the cleft sites and placement of implants exceeded six months in most patients, but the grafted bone remained, and all implants were completely covered by host or grafted bone, with or without added bone substitutes or bone particles obtained during the drilling process for implant placement. Hydroxyapatite allografts were used in three patients, none of whom had signs or symptoms of infection or peri-implantitis at the grafted sites. Our results suggest that aesthetic outcomes may depend on the number of risk factors rather than the presence of high-risk factors. Two patients with no high-risk factors had a high-risk factor previously (width of the edentulous span), which was remedied by orthodontic treatment before implant surgery. Thus, it is important to reduce the number of high-risk factors to obtain good aesthetic outcomes from dental implant treatment for alveolar cleft patients.
