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 -
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. -

A RANDOMISED CLINICAL TRIAL FOR RIDGE PRESERVATION USING TWO TYPES OF COLLAGENATED XENOGRAFT/COLLAGEN MEMBRANE—A CONE-BEAM CT STUDY
Objectives: This randomised controlled clinical trial aimed to radiographically compare horizontal and vertical alteration of alveolar ridge following extraction-socket grafting with different combinations of biomaterials: collagenated porcine bone and cross-linked collagen membrane (test group) versus collagenated bovine bone and non-cross-linked collagen membrane (control group). Methods: This study included patients who required at least one anterior or premolar extraction, were aged 20 years old or more, and were able to understand the informed consent. Tooth replacement was planned using either conventional or implant-supported fixed partial dentures. Sample size calculations required 13 patients per group to obtain 80% power at a two-sided alpha level of 0.05%. A total of 30 patients were enrolled, and 15 were randomly allocated to each group. All were blinded to their allocations. Following a single tooth extraction, a collagenated bone substitute was used to fill in the socket, and a collagen membrane was used to cover it. Primary flap closure with several flap designs was attempted. Cone-beam CT (CBCT) scanning was carried out to assess the change in alveolar ridge, once immediately after ridge preservation and once after 4 months of healing. The primary outcome was horizontal alteration of alveolar ridge. Secondary outcomes were vertical alteration of alveolar ridge and clinical handling of the bone substitute and barrier membrane. Results: One patient in the control group dropped out and 3 patients did not receive the allocated intervention in the test group. Intention-to-treat (ITT; control group 14, test group 15) and per protocol (PP; control group 14, test group 12) analyses were performed. In the control and test group, 8 and 7 cases, respectively, showed membrane exposure, secondary healing was uneventful in all cases. There was no statistical difference in ITT and PP analysis between the groups in horizontal alteration of alveolar ridge width, but vertical height in the midfacial area was significantly reduced in the test group. The handling properties of the barrier membrane showed no statistically differences, but the handling properties of the bone substitute was significantly superior in the control group. Conclusions: Ridge preservation using collagenated porcine bone/cross-linked collagen membrane showed similar horizontal ridge alteration to collagenated bovine bone/non-cross-linked collagen membrane. However, vertical ridge changes were more pronounced with the collagenated porcine bone/cross-linked collagen membrane. Further studies including histometric evaluation are required.
