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. -

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. -

Compromised Bone Healing
The bone healing process in people can be affected by diseases such as Crohn’s disease, diabetes and colitis. It can also be affected by drugs such as bisphosphonates, which are used to treat weak bones in people with osteoporosis, Paget's disease and certain cancers. The role of animal models is enormous for investigating these disease conditions as well as other “risk factors” for compromised healing, such as radiotherapy, which is being increasingly used as early treatment of cancer in the community rises. Diabetes and intestinal disorders can be induced in rats, often using chemicals with toxic effects, but the diseases can take some time to develop. This chapter gives guidance on various timeframes for evaluating inflammatory processes, osseointegration and collagen cross-linking, and gives details on mechanical strength testing of dental implants and other candidate therapies. Different aspects of the compromised bone healing response can be observed using both the long bones (tibia and femur) and the maxilla of rats. This chapter also describes an adaptable study protocol for new investigators, with suitable endpoints such as bone to tissue ratio and bone to implant contact, to contribute to the body of knowledge on patients with compromised bone healing who are increasingly encountered in dental practice. -
Pectin nanocoating of titanium implant surfaces - an experimental study in rabbits
Objectives: The aim of the study was to evaluate the effect of nanocoating titanium implants with plant cell wall-derived rhamnogalacturonan-I, on bone healing and osseointegration. A new strategy to improve osseointegration and bone healing is biochemical stimulation by surface nanocoatings that may increase adhesion of bone proteins, and bone cells at the implant surface. Nanocoating with pectins, plant cell wall-derived polysaccharides, is frequently done using rhamnogalacturonan-I (RG-I). Methods: Machined titanium implants were coated with three modifications of rhamnogalacturonan-I (RG-I). Chemical and physical surface properties were examined before insertion of nanocoated implants (n = 96) into the left and right tibia of rabbits. Machined titanium implants without RG-I nanocoating were used as controls (n = 32). Total number of 128 implants was placed in tibias of 16 rabbits. Fluorochrome bone labels, calcein green and alizarin red S were given intravenously after 9 and 12 days, respectively. The bone response to the nanocoated implants was analyzed qualitatively and quantitatively after 2, 4, 6, and 8 weeks of healing using light microscopy and histomorphometric methods. Results: The RG-I coating influenced the surface chemical composition; wettability and roughness, making the surface more hydrophilic without any major effect on surface micro roughness compared to control implant surfaces.The different modifications of pectin RG-I did not significantly enhance bone healing and osseointegration analyzed after 2, 4, 6, and 8 weeks of healing compared to control implants. Although the qualitative analyses of the fluorochromes indicated a higher activity of bone formation in the mineralization front at the early stage, after 9 and 12 days at the RG-I nanocoated implants compared to the control implants although no significant quantitative difference was demonstrated. Conclusion: The present study showed that nanocoating of titanium implants with pectin RG-Is did not significantly enhance bone healing and osseointegration when placed in rabbit tibia bone. -
Periodontal Screening Index PSI
Belz, DieterMit diesem Beitrag wollen wir die Einführung des PSI, "Parodontal Screening Index", unterstützen. PSI ist ein Blutungsindex, der in vielen Ländern offiziell empfohlen und angewendet wird. Auch in Deutschland haben sich die Standesorganisationen sehr erfolgreich dieser Aufgabe gewidmet, so daß die WHO-Sonde wochenlang ausverkauft war. Bei der starken Verbreitung von Parodontitis in allen Schichten und Alterstufen der Bevölkerung erscheint die Einführung eines Index als Bestandteil der zahnärztlichen Diagnostiknatürlich als sehr hilfreich. Schließlich ist die Parodontitis die am weitesten verbreitete Krankheit überhaupt. Soll sich ein Index in der Alltagspraxis durchsetzen, so muß er einfach und schnell zu erheben ein. Dies ist hier nach übereinstimmender Beurteilung der Fall. Unser Bericht macht sie mit dem PSI und seiner Anwendung vertraut.
