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.

PERI-IMPLANT BONE REACTIONS TO DIFFERENT IMPLANT MACROSTRUCTURE AND NECK CONFIGURATIONS—A 5-YEAR STUDY WITH 494 IMPLANTS
Objectives: After implant placement, bone remodelling can be observed along the entire implant, but it is more dominant at the level of the implant neck. To date, there have been few long-term studies on the effectiveness of different implant necks and macrostructures for preserving marginal bone. The primary endpoint of this study was to clinically investigate the influence of different implant macrostructure and neck configurations on peri-implant marginal bone loss. Methods: Cylindrical and tapered implants were compared. Statistical analysis was performed using IBM SPSS version 20. Descriptive analysis included the number of implants and mean marginal bone loss for all groups. Results: Cylindrical implants with an external hexagon connection(n=321) featured the greatest marginal bone loss (distance between implant shoulder and bone crest (DIB) 2.341mm ± 1.184). Cylindrical implants with an internal hexagon connection(n=86) displayed less marginal bone loss compared to external connections with the same macrostructure (mean DIB 2.193mm ± 1.121). In contrast, tapered implants with an external hexagon (n=33) showed less bone loss (mean DIB 1.422mm ± 1.063) than those with an internal hexagon (n=54) (mean DIB 1.951mm ±0.793). Statistically significantly differences were found between external hexagon implants with different implant macrostructures. Conclusion: There was a trend for peri-implant marginal bone loss to be directly affected by implant macrostructure. Tapered implants may lead to less marginal bone loss after 5 years compared to cylindrical implants, and may be considered as safe and predictable alternatives. -
THE INFLUENCE OF PIEZOSURGERY ON BONE HEALING AROUND TITANIUM IMPLANTS – A HISTOLOGICAL STUDY IN RATS
Marcelo Sirolli(Brazil), Carlos Eduardo Secco Mafra, Rodrigo Albuquerque Basílio dos Santos, Luciana Saraiva, Marinella Holzhausen, João Batista César Neto Objectives: The aim of this study was to investigate the influence of two techniques for dental implant site preparation on bone healing around titanium implants. Methods: Fifteen male Wistar rats (weighing approximately 300g) were used. Tibias were randomly assigned to undergo implant site preparation with a conventional drilling technique (control group) or piezoelectric device (piezo group). After 30 days, they were sacrificed and the following histomorphometric parameters were evaluated separately for cortical and cancellous tibial regions: proportion of mineralised tissue (PMT) adjacent to implant threads (500μm adjacent); bone area within the threads (BA); and bone–implant contact (BIC). Results: There were no differences between the two groups for cancellous BIC (p>0.05) and cortical PMT (p>0.05). A higher mean percentage of BA was observed in the piezo group in cortical regions (controls 71.50% ± 6.91 and piezo group 78.28% ± 4.38; pin cancellous regions (controls 9.35% ± 5.54 and piezo 18.72% ± 13.21; p Conclusion: Within the limits this study on implant site preparation, we conclude that piezosurgery favours bone healing rates in cancellous bone regions, while the drill technique gives better results in cortical regions. -
A COMPARATIVE ANALYSIS OF DEMINERALISED FREEZE-DRIED BONE (DFDBA), FRESH FROZEN BONE ALLOGRAFT (FFBA) AND AUTOGENOUS BONE GRAFT (AU)—A HISTOLOGIC STUDY IN RABBITS
Objectives: There are different clinical applications for bone grafts in alveolar reconstructions and difficulties in achieving vertical osseous increase. This study was to make a comparative histological evaluation of DFDBA, FFBA, AU and blood clot (CO) on vertical guided bone regeneration (GBR) in rabbit calvaria. Methods: Nine rabbits were used. One was the primary bone graft donor and eight were GBR models, whereby 32 titanium cylinders were fixed to the calvaria and randomly filled with DFDBA, FFBA, AU or CO. The animals were killed 13 weeks later and the contents of the cylinders were analysed histomorphologically and histomorphometrically to quantify the total area (AT) of newly formed tissue, new bone (NB) and residual graft (RG) particles. Results: Mean values of AT were significantly higher for DFDBA and FFBA in the order DFDBA = FFBA > AU > CO. New bone formation with DFDBA and FFBA was better than with AU or CO. There were more RG particles in the DFDBA models, in the order FFBA > DFDBA = AU = CO (p values Conclusions: Allografts containing DFDBA and FFBA can be considered beneficial for achieving new vertical bone formation.
