This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Background: Osteoporosis is associated to decrease of bone mineral density, leading to an increase of skeletal frailty and fracture risk. Surface characteristics of dental implants may influence bone response, modulating cell proliferation and differentiation. Nanostructures applied to biomaterials may contribute to a higher bone to implant contact. Previous studies have shown that Leukocyte platelet rich fibrin (L-PRF) can increase the amount and formation rate of new bone around implants.Aim: To micro-tomographically evaluate, in osteoporotic rats, the bone repair around two implant surfaces, associated of not to L-PRF, analyzing Bone to Implant Contact (IS/TS,%), Bone Volume Fraction (BV/TV,%), Bone Surface/Volume (BS/BV,%) Trabecular Thickness (Tb.Th,mm), and Total Porosity (To.Po,%).Material and methods: Mini implants with 2 types of surface (double acid etched=DAE, or with the addition of nano-hydroxyapatite = NHA; 24 implants of each type) were installed in the tibias of osteoporotic rats. In 24 rats, L-PRF was obtained with blood collection by means of cardiac puncture and posterior centrifugation, and inserted in the prepared bone site before implant insertion. The 48 rats were randomly divided into 4 experimental groups of 12 rats each: G1- DAE implants installed; G2- NHA implants installed; G3- DAE implants installed in association to L-PRF; G4- NHA implants installed in association to L-PRF. All the mini implants were prepared for the study, measured 2.7mm in length x 1.4mm in diameter, and had the same macrostructure. The animals were euthanized 7 and 30 days (7d and 30d) after implants placement (6 from each group/period). The tibias were removed for microtomographic evaluation of the bone between the threads of the implants, analyzing the previously described parameters.Results: Inter-groups differences were assessed using One-way Analysis of Variance (p

Available in PDF, EPUB and Kindle. Book excerpt: The use of dental implants has been an extremely relevant tool in oral rehabilitation. However, there are systemic conditions, such as osteoporosis, that may negatively influence the osseointegration process by decreasing bone mineral density. Modifications in the microtopography and surface of the implants, as well as the use of the Leukocyte Fibrin Rich Plasma (LPRF), are strategies that have been used to increase bone healing around the implant.

Download or read book Fuzzy Sets Theory and Applications written by André Jones and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 405 pages. Available in PDF, EPUB and Kindle. Book excerpt: Problems in decision making and in other areas such as pattern recogni tion, control, structural engineering etc. involve numerous aspects of uncertainty. Additional vagueness is introduced as models become more complex but not necessarily more meaningful by the added details. During the last two decades one has become more and more aware of the fact that not all this uncertainty is of stochastic (random) cha racter and that, therefore, it can not be modelled appropriately by probability theory. This becomes the more obvious the more we want to represent formally human knowledge. As far as uncertain data are concerned, we have neither instru ments nor reasoning at our disposal as well defined and unquestionable as those used in the probability theory. This almost infallible do main is the result of a tremendous work by the whole scientific world. But when measures are dubious, bad or no longer possible and when we really have to make use of the richness of human reasoning in its variety, then the theories dealing with the treatment of uncertainty, some quite new and other ones older, provide the required complement, and fill in the gap left in the field of knowledge representation. Nowadays, various theories are widely used: fuzzy sets, belief function, the convenient associations between probability and fuzzines~ etc ••• We are more and more in need of a wide range of instruments and theories to build models that are more and more adapted to the most complex systems.
