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.

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.

Objectives: Use of a soft tissue graft for recession coverage at tooth 23 and for gingival augmentation. Content: 1. Incision around tooth 23, intra-sulcular preparation, mobilization of coronal sliding flap, and pre-flap preparation. 2. Root smoothing, reduction of ground cavity with diamond burs from Perioset system. 3. Preparation and harvesting of connective tissue flap from palate, Emdogain application, and wound closure. 4. Placement of interrupted interdental sutures for fixation of connective tissue flap.

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.

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.

Content: - Periodontal maintenance therapy for teeth 34 and 35, including the regeneration of a bone defect using bone replacement material, collagen membrane and sutures. - Curettage for treatment of periodontal pockets. - Treatment of gingival pressure sores caused by tight-fitting orthodontic apparatus. - Incision of buccal attachment to relieve gingival pressure for elimination of gingival recession.

Dr. Dominik Büchi performed a ridge preservation to keep the soft tissue volume. He then placed an implant 8 weeks later with simultaneous GBR. The final emergence profile was created by a fixed provisional crown.

The invisible becomes visible and holds both challenge and fascination. The cellular-level biological processes that underlie osseointegration are visualized based on the cell types and messengers implicated, representing the current state of our knowledge. Complex biodynamic processes are showcased dramatically and didactically to support the transfer of knowledge in training and education. Module 1, Cell-To-Cell Communication - Osseointegration, ushers in an Initiative for Excellence entitled Education - Science Comes Alive. It will eventually present all the relevant biomedical processes in dentistry and oral and maxillofacial surgery in the form of 3D animations, to be made available to a professional public as a 3D film library. This innovative genre - with special highlights for every viewer - will open up interesting teaching and training perspectives.

Procedure: - Incision Technique 36, 44 - Gentle Flap Mobilization - Pilot Hole Preparation using a CT Template - Sequential Preparation and Implantation - Bone Removal and Augmentation - Wound Closure Contents: Systematic Total Rehabilitation is very challenging, especially in patients with Periodontal Disease with Loss of Supporting Structures. Precise Treatment Planning is essential. The Treatment of Periodontal Disease begins after Conservative Pretreatment. It is not possible to predict the Soft Tissue Esthetic Outcome before the Healing Process is completed. We selected Endosteal Implants for the Augmentation of Lost Support Zones in this Atrophic Mandible. A Three-Dimensional Analysis was performed as the Basis for Navigated Implantation. After Completion of the Periodontal Treatment and Implantation, the patient must wait for approximately 6 months for the Completion of the Healing Process before Prosthetic Reconstruction Procedures can be initiated.

Morphological abnormalities such as peg-shaped laterals are quite frequent dental problems which must be addressed by restorative means. An ideal aesthetic correction can be achieved with minimal or no-loss of tissue, what is known as "Minimally Invasive Dentistry", a concept becoming popular also in Aesthetic Dentistry. This video demonstrates the reconstruction of two lateral incisors with direct composite application, following the "Natural Layering Concept", which implies the use of separate dentin and enamel increments, mimicking the natural tooth anatomy. Step by step procedures will be detailed, which include shade selection, placement of the rubber dam, adhesive procedures, dentin and enamel build-up and finishing-polishing procedures, which finalize the restorative work. By following a precise and meticulous operative protocol, perfectly natural looking restorations can be produced, in a predictable way.
