    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.

    Soft Tissue Management in the Aesthetic Zone

    Daniel Thoma
    Expert 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, Hendrik
    Visualizing 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, Ueli
    Procedure: - 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.

    Regenerative Procedures for Optimized Esthetics at Tooth 11

    Schlee, Markus
    Contents: - Exploration - Incision and Flap Mobilization - Palatal Flap Preservation with Interdental Tissue Preservation - Detoxification and Concrement Removal at 11 - Harvesting of Autogenous Bone Chips from the Spina Nasalis - Conditioning of the Root Surface with EDTA-Gel - Application of Emdogain and Filling of the Bone Defect - Wound Closure Synopsis After Finishing the Initial Treatment for Aggressive Periodontitis, Regenerative Treatment of a Tunnel-Shaped Pocket at Tooth 11 was attempted. Rotation and Crowding of the Buccally Inclined Tooth represented a favorable Etiological Factor. The patient did not wish to receive Orthodontic Treatment to eliminate this Causal Factor after Completion of Primary Treatment. Treatment was therefore limited to the Surgical Regeneration Attempt. The Interdental Space was larger than 3 mm and the Bone Pocket was a mostly Three-Walled Structure, so the Chances of Success were considered to be good. Exploration was first performed to identify the Course of the Defect Margins. Exact knowledge of the Bone Anatomy in all three Planes is essential to successful Incision Planning. A Tunnel-Shaped Defect delimited by Bone in the Region of Tooth 11 with good chances of Periodontal Regeneration was found. A major Challenge of this Procedure is the need to keep the Defect completely covered with Soft Tissue throughout the Healing Process. Cortellini's Papilla Preservation Technique was used for this Purpose. After Incision and Flap Mobilization, it became evident that the Defect only had two Walls in the Coronal Region and that Bone was lacking in the Buccal Region. According to the current Data on Periodontal Regeneration, the Attachment Gain achieved using an Enamel Matrix Protein (Emdogain®) alone can be just as good as that achieved using Emdogain and Bone Graft Material combined. Still, we elected to use a Combination Technique in the Present Case because it provides better Papillary Support. The Graft Material consisted of Autogenous Bone Chips from the Spina Nasalis, which can easily be harvested by Means of the Piezo Technique After gentle Detoxification, the Root Surface was treated with Emdogain. The Defect was then filled with Autogenous Bone Chips and closed by Microsurgical Suture Techniques. Six months after Surgery, Partial Regeneration of the Papilla can be seen.
