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 -

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. -

IS RIDGE PRESERVATION SAFE OR NOT IN INFECTED SOCKETS? A RETROSPECTIVE DATA ANALYSIS
Objectives: To date, most previous work evaluating healing after tooth extraction has included only fresh extraction sockets. In normal clinic practise, however, the indications for extractions are more complex and certain pathologies are associated with destruction of the socket walls, often resulting in severe resorption. The aim of this study was to evaluate the safety of ridge preservation in infected sockets. Methods: A total of 320 dental records from Seoul National University Dental Hospital archives (January 2011–November 2015) including patients who received extraction due to infection and immediate ridge preservation in the Department of Periodontics were evaluated. the exclusion criteria were as follows: i) ridge preservation in fresh sockets which were extracted due to caries and fracture (excluding retained roots); ii) ridge preservation performed with non-resorbable membrane; iii) age less than 20 years; iv) repetitive medication administration with anti-inflammatory drugs (excluding rheumatoid disease); iv) current pregnancy; and v) history of autoimmune disease. Records were reviewed to identify cases where infection was present (endodontic origin, periodontal origin, and combined endodontic–periodontal origin), which was removed by meticulous debridement and immediately grafted with a biomaterial. The following data were retrieved from the hospital database records: pathologic origin, success and failure rates of the attempted ridge procedure technique, and preservation in infected sockets. Results: A total of 320 ridge preservation surgeries were performed and 13 cases not meeting the inclusion criteria were excluded. Of the 307 eligible subjects, 9 cases (2.93%) were classified as endodontic origin, 198 (64.50%) as periodontal, 90 (29.31%) as combined endodontic-periodontal and 10 (3.26%) unknown. Uneventful healing was observed in 299 sites (97.39%) with no additional medication, whereas six sites (1.95%) needed additional medication (5 days of additional antibiotics) due to inflammatory symptoms. Re-infection occurred in two sites and the biomaterials within the socket were removed. Clinical symptoms included abscess with pus formation, caustic odour, pain and severe bleeding. The cause for failure in site 1 may be attributed to overfilling of the biomaterial attracting new infection source and complicating the closure of the wound. In site2, necrotic bone plate and/or retained root-like radiopacity observed in the CT, suggesting incomplete removal of the infection source within the socket. Besides these two cases of infection, ridge preservation was successful in 305 sites, yielding a high success rate of 99.35%. Conclusion: Within the limitation of this study, our observations suggest that immediate ridge preservation with various biomaterials is a safe procedure, despite the need to graft immediately following tooth extraction and to remove the infection source using the conventional debridement method. Caution is needed when performing debridement so as not to leave root fragments or necrotic bone plates unremoved. Also, overfilling may compromise wound stability at the entrance of the socket and must be avoided for optimum results.
