Long-term bone remodelling of implant placed in the posterior mandibule: a radiological study. France Lambert, Kim Vincent, Caroline Geron, Geoffrey Lecloux, Eric Rompen. Purpose: The aim of this study was to analyse direct and long-term (4 years) marginal bone remodelling of various implant systems placed in the posterior mandibule with a single stage approach. Materials and methods: 50 partially edentulous patients received a total of 114 implants in the posterior mandibule (TE implant, Straumann®, Switzerland; Replace® Select Straight, Nobel Biocare, Sweden; Branemark System® MKIV, Nobel Biocare, Sweden). All implants were non-submerged, and loaded 8 to 12 weeks post surgery. X-rays were taken at baseline, 6 weeks, after loading and at long-term. Using a image processing program (Image J), bone losses were measured at each time point. Bone levels were also recorded using the first thread as reference point. Results: The mean bone loss reached 0.506±0.498 mm at 6 weeks, 0.798±0.599 after loading and 1.037±0.799 after 4 years. Bone losses were significatively higher on smokers and on patients displaying signs of bruxism. No statistical difference was found between the different implant types. Conclusion: 50% of the bone loss had already occurred within the 6 weeks post surgery with all implant types. Higher bone losses were often associated to risk factors such as tabacco addiction and bruxism. [less ▲]

The aim of this study was to determine whether it is safe to use photo-activated disinfection (PAD) during root canal treatment without heating the periodontal tissues. Root canals of 30 freshly extracted single-rooted teeth were prepared using ProFiles up to size ISO 40 and then filled with photo-sensitiser: tolonium blue (1.2 mg/l). The 635 nm diode laser was used with the manufacturer's endo-tip. Samples were irradiated for 150 s (output power 100 mW, approximate energy density 106.16 J/cm(2)). Temperatures were recorded at working length on the external root surface. After 150 s of PAD irradiation, the average temperature rise was 0.16 +/- 0.08 degrees C. All values were lower than the 7 degrees C safety level for periodontal injury. It was concluded that, regarding the temperature increase, the use of PAD in root canals could be considered harmless for periodontal tissues. [less ▲]

In this study, we compared the microleakage of composite fillings cured with halogen bulb, LED and argon ion laser (488 nm). Twenty-four extracted human molars were divided randomly in three groups. Six cavities were prepared on the coronal part of each tooth. Standard cavities (1.7 x 2 mm) were prepared. Cavities were acid etched, sealed with Scotch Bond 1 and filled by a hybrid composite. Cavities were exposed to one light source, thermocycled and immersed in a 2% methylene blue dye solution. Dye penetration in the leakage of cavities was recorded using a digital optical microscope. Mean values of percentage of dye penetrations in microleakages of cavities were 49.303 +/- 5.178% for cavities cured with LED, 44.486 +/- 6.075% with halogen bulb and 36.647 +/- 5.936% for those cured by argon laser. Statistically significant difference exists between cavities cured by halogen vs LED (P < 0.01), halogen vs laser (P < 0.001) and LED vs laser (P < 0.001). The lowest microleakage was observed in the cavities and composites cured with argon ion laser. [less ▲]

Introduction The first part of the study devoted to guided tissue regenerative membranes was focused on a better understanding of the physicochemical and mechanical properties of commercial materials. The second objective of our study was to develop an in vitro device able to measure the long-term barrier effect of resorbable membranes. After the development of this new device, experiments were realized to characterize the long-term behaviour of commercially membranes with human gingival fibroblasts (HGF). Materials and methods The use of human gingival fibroblastic cells was chosen to get closer to biological conditions. Some gingival explants were removed in young and non-smoking healthy patients. From these explants, fibroblastic cells were isolated and cultivated. These cells will be able to be used between the third and the sixth passage. Resorbable membranes were chosen because they don’t require a second surgical operation. There are made of polyesters or collagen. A system based on inserts was developed in order to follow the degradation of membranes and the migration of cells across the material. The membrane was cut into 8 mm diameter punches and set in the bottom of the system. Once the whole was put together, it is laced into a 12 wells plate culture. First, the plates were put in an incubator at 37°C, during times ranging from 24 hours to several months. The barrier effect was then measured to reflect the gradual increase of permeability of each membrane. For this purpose, HGF were seeded on the different samples. The top of the bottle and the bottom of the well were then filled with culture medium. Non degradable synthetic Bioflex membranes were chosen as control samples which don't let pass cells (porosity : 0,4 µm). After 48 hours of incubation in the presence of cells, pictures of cells on membranes and in the bottom of wells were taken with an optic microscope. Viability tests (MTS) were then realized on membranes to evaluate cells proliferation and in the bottom of wells to measure barrier effect. Finally, the morphology of cells on selected membranes was characterized by Scanning Electron Microscopy. Conclusion Proliferation results correspond to data published by several authors. Furthermore, the barrier effect times found in the present study are similar to barrier effect times demonstrated in in vivo studies and announced by manufacturers. In conclusion, the finalized system is adapted to the analysis of long-term barrier effect of commercial GTR membranes. This system will be tested with synthetic bioresorbable membranes made of copolymers. [less ▲]

Sinus floor elevation is a technique allowing implant placement in the posterior edentulous maxilla when residual bone height is limited. This technique has evolved a lot since it has been first introduced in the eighties. Nowadays, this approach is considered as predictable, simple and practicable under local anaesthesia. This present article aims at understanding clearly the biological phenomenon of “sinus- lift”. Moreover, the surgical protocol used at the University of Liège is considered didactically and reasoned according to the scientific literature. [less ▲]

L’élévation du plancher sinusal est une technique permettant de placer des implants d’une longueur suffisante au niveau du maxillaire postérieur. Depuis qu’elle a été initialement décrite dans les années 80, cette technique a beaucoup évolué. A l’heure actuelle, on peut considérer cette approche comme prédictible, simple et réalisable au fauteuil sous anesthésie locale. Cet article vise d’abord à expliciter clairement le phénomène biologique du « sinus-lift », ensuite, de décrire le protocole chirurgical que nous appliquons à l’Université de Liège (Belgique) et de le confronter avec la littérature scientifique existante.
