Instrumentatie In diverse onderzoeken van de afgelopen decennia zijn verschillende mechanische instru- menten op verschillende implantaatoppervlakken getest: metalen handinstrumenten cheap zithromax line, niet-metalen handinstrumenten cheap 250mg zithromax overnight delivery, (ultra)sone scalers met metalen of niet-metalen tips buy cheap zithromax on line, air polishers met diverse poeders, polijstcupjes/puntjes met of zonder polijstpasta en diamant-/ carbideboren. In hoofdstuk 2 werd in de literatuur gezocht naar wetenschappelijk bewijs voor de te verwachten effecten van diverse mechanische instrumenten op de oppervlaktestructuur van gladde en ruwe titaniumoppervlakken. De uitkomsten van dit review tonen dat air polishers, niet-metalen instrumenten en rubber polijst cupjes geen of minimale schade aan gladde titaniumoppervlakken toebrengen en daardoor veilig toegepast kunnen worden in de nazorg van patiënten met implantaten. Als er geen veranderingen in de oppervlaktestructuur van Nederlandse samenvatting 241 ruwe implantaatoppervlakken mag worden aangebracht, lijken niet-metalen instrumenten en de air polisher de meest geschikte instrumenten. Als het doel is het ruwe implantaatop- pervlak juist gladder te maken en bijvoorbeeld ook de schroefwindingen te verwijderen, dan worden diamant-/carbideboren aanbevolen. Dit bijvoorbeeld ten behoeve van implantoplas- tie wanneer het ruwe implantaatoppervlak is blootgesteld aan het orale milieu. Misschien nog belangrijker dan het effect van een instrument op de oppervlakte struc- tuur is of een instrument effectief is in het reinigen van het oppervlak. In hoofdstuk 3 werd bekeken welke mechanische instrumenten effectief zijn in het reinigen van het implantaat- oppervlak en het verwijderen van bioflm. De resultaten van deze review duiden erop dat air polishers de meest effectieve instrumenten zijn voor het verwijderen van bioflm van zowel gladde als ruwe titaniumoppervlakken. De literatuur laat verder zien dat de effectiviteit van alle mechanische instrumenten bij het verwijderen van tandsteen beperkt is. Bacteriële contaminatie kan de chemische samenstelling van een titaniumoppervlak veranderen. Ook kan instrumentatie een ongunstig invloed hebben op de samenstelling en oppervlaktestructuur van een titaniumoppervlak. In hoofdstuk 4 werd bekeken wat het effect van de diverse mechanische instrumenten op de biocompatibiliteit van het implantaatoppervlak is. Van alle geteste instrumenten blijkt de air-polisher het minst negatieve effect te hebben. In hoofdstuk 5 werd onder- zocht wat de invloed van de diverse poeders op de cellen die in het peri-implantaire weefsel voorkomen kan zijn. De selectie van het meest geschikte poeder lijkt van belang te zijn voor de genezing. Geen van de mechanische instrumenten blijkt alle bioflm van het titaniumoppervlak te ver- wijderen, zeker als het oppervlak moeilijk bereikbaar is. Er kan dus ook overwogen worden om de behandeling met chemische middelen te combineren. Hiermee kunnen dan de bac- teriën die op de titaniumoppervlakken zijn achtergebleven alsnog mee worden gedood. In hoofdstuk 6 werden chemische middelen geëvalueerd in relatie tot de bioflm op het titaniu- moppervlak. In dit hoofdstuk werd bekeken welke middelen effectief zijn in het verwijderen 242 Nederlandse samenvatting en afdoden van bioflm van titanium implantaatoppervlakken. Het gebruik van een zuur (etsgel) lijkt hierbij op dit moment het meest effectief. Zelfzorg Het onderhoud van de implantaat-gedragen constructies is grotendeels de verantwoordelijk- heid van de patiënt en het is afhankelijk van de dagelijkse plaque-beheersing. In hoofdstuk 7 werd in de literatuur gezocht hoe een patiënt het beste een implantaat-gedragen constructie zou kunnen reinigen. Hoewel elektrisch poetsen niet superieur blijkt te zijn vergeleken met poetsen met een handtandenborstel, kan het helpen om beperkingen in de handvaardigheid te beperken en de toegankelijkheid van de te reinigen constructies te verbeteren. Wat de interdentale reiniging betreft, is foss geen goed middel als een ruwe implantaatoppervlak blootgesteld is aan het orale milieu. Van systematische reviews tot een klinische richtlijn De laatste jaren wordt in de medische wereld de ontwikkeling van klinische richtlijnen na- gestreefd. Periodieke controles en zorgvuldig onderhoud zijn van groot belang om peri-implantaire ziektes te voorkomen of ze vroegtijdig te diagnosti- ceren. Vroegtijdige diagnose van ontsteking en botverlies rondom implantaten is essentieel om tijdig adequate therapie te bieden. Echter door de grote variatie in type van implantaten, methodiek van plaatsing ten opzichte van omliggende structuren zoals bot en zachte weef- sels maar ook de vorm van de vervaardigde constructie, is er geen universeel referentiepunt voor het vaststellen van gezond of ongezond. Daarmee is deze ‘nulmeting’ een onmisbaar onderdeel voor de start van de controles van de implantaat-gedragen constructies. De klini- sche ‘nulmeting’ vindt bij voorkeur ongeveer acht weken na het plaatsen van de suprastruc- tuur plaats, zodat het peri-implantaire weefsel zich eerst aan de constructie heeft kunnen adapteren. Al met al geeft dit proefschrift kort samengevat aan dat: het voorkomen van peri-implantaire infecties beter is dan genezen!

Thanks to Dick I came in contact with Fridus van der Weijden, a visionary, a true scien- tist who is continuously seeking new knowledge. He introduced me into the world of science, stimulating me with not only scientifc but also philosophical discussions, coaching and motivating me. She has an unbelievable gift in fnding solutions even for the most challenging situations. Last but not least I want to thank my parents Dimitis and Athina and my husband Pav- los, my steady companions in my pursuit of knowledge. Thank you for all the sacrifces you did, the psychological and physical support and the encouragement you provided me.

Local tissue stimulation is considered to stir disturbances in the tissue-producing microinflammation cheap zithromax 250mg without a prescription. Mediators of the inflammation are observed to convey a message to the center of the autonomic nervous system that decodes the message 376 13 Neuroimmuno-effect of Acupuncture on Immune-mediated Disorders received and precedes the feedback to the related organs and targets buy zithromax once a day. Acupuncture has been observed to produce alteration in the secretion of neurotransmitters buy generic zithromax pills, neurohormones, and immune functions-related cytokines, and changes in the regulation of blood flow, both centrally and peripherally (Cabio÷lu 2008). It has been reported that many hormones have their own receptors expressed on the macrophages, T-lymphocytes, and B-lymphocytes. Furthermore, immune cells are observed to secrete various neuropeptides and hormones, known as immune transmitters as a whole. In addition, some neuroendocrine cells are observed to secrete certain substances that can influence the neuroendocrine system and immune system. Nervous, endocrine, and immune systems can communicate and complement each other via these substances and their respective receptors. Basically, immune cells and other immune competent cells function as the body defense system, recognizing foreign antigens and secreting immune transmitters. The immune transmitters can convey the information to the nervous and endocrine systems, by magnifying and initiating the signal. On the other hand, the nervous and endocrine systems can directly or indirectly function on the immune cells through impulses or secreted neurotransmitters and hormones. Network of bidirectional communication between central nervous system, peripheral nervous system, endocrine system, and immune system. Clearly, acupuncture is based on the view that the human body must be perceived and treated as a whole and as a part of nature; hence, the regulatory effect of acupuncture on the nervous, endocrine, and immune systems cannot be separated from each other, and are dependent on the neuroendocrine-immune regulatory 377 Acupuncture Therapy of Neurological Diseases: A Neurobiological View network. In addition to its direct regulation of these systems, acupuncture is also observed to indirectly act upon the other systems by reopening the normal energy flow, and subsequently affecting the neuroendocrine-immune regulatory network. In an earlier study on acupuncture analgesia, the role played by the hypothalamus and the released endorphin in acupuncture analgesia was observed to be most convincing. Acupuncture is observed to exert its function via the peripheral sensory nerves and sympathetic trunks, and finally on the hypothalamus. These hormones expressed in the pituitary gland subsequently reach the adrenal gland, and trigger the release of corticosteroids, adrenalin, thyroid hormones, estrogen, progesterone, oxytocin, prolactin, relaxin, insulin, etc. The effect of acupuncture was well examined at this stage and was reported to show acupoints specificity on substances released in this pathway, but with unknown mechanism (Gong and Wang 1997). They found that either cellular- or hormonal-mediated immune function was suppressed in the mice receiving cortisol treatment. However, adrenalectomy was observed to overcome this effect, restoring the immune response to almost normal level. These data suggest that there is a relationship between the immune and the pituitary functions. All these mediators alter several aspects of the immune function, including antibody production, cytokine production profiles, and cell trafficking. Brain as the central nervous system is also considered to host immune cells or immune competent cells, thus, becoming involved in the immune response and protecting itself from invasion (Fig. Many studies have demonstrated that bi-directional communication between the nervous and immune systems is through the neuroimmune mediators (neuropeptides, hormones, cytokines, and chemokines) as well as the respective receptors expressed within these two systems. Stimulators like virus, bacteria, dead cells or debris, and toxic central nervous system proteins, could be recognized by the immune competent cells, and subsequently, immune responses are initiated. In this process, proinflammatory cytokines, chemokines, and neurotransmitters are found to be involved. Endogenous opioid peptides and their receptors are one of the important molecules. The fact that endogenous opioid peptides are implicated in the antinociception was established several decades ago. Recently, the coupling between the pain and immune response via the common signaling molecules was reinforced by opioid- related studies. Opioid peptides, such as E-endorphin and met-enkephalin, have been reported to be closely associated with the cellular and humoral immunity, and are considered to work as the mediators between the central nervous system and the immune system. In addition, monocyte phagocytosis was increased in 45% of the cases after 30 min of treatment, and in the rest of the cases, it increased after 24 h of treatment. Over the last several years, numerous evidences have been obtained on the underlying pathophysiological mechanism of acupuncture. Stimulation of different acupoints could produce a certain amount of neurotransmitters, neuromodulators, neurohormones, and cytokines. They can either directly affect the components of the immune system, or indirectly, by activating the neuroendocrine axis. Therefore, acupuncture could stimulate the body’s ability to resist or overcome illnesses and conditions by correcting the imbalances as well as the communication between 383 Acupuncture Therapy of Neurological Diseases: A Neurobiological View nervous system and immune system. From the modern perspective, the human body has been finally described in terms of cells, biochemicals, and specific structures. Modern studies have revealed that acupuncture stimulates one or more of the signaling systems, which can, under certain circumstances, increase the rate of healing process. Thus, acupuncture and its underlying concepts are gradually being examined and must be evaluated based on the new concepts. We understand that the Chinese therapeutic principle is to achieve stability by adjusting and harmonizing the internal element/organic environment. We also perceive that the scientific basis of immunomodulatory effects of acupuncture correspond to the modern notion of reestablishing homeostasis by regulating the interactions between the autonomic nervous system, the innate immunity, and several other systems. Furthermore, we can be benefited from the progress in molecular biology, and subsequently, integrative physiology and clinical research, which could reasonably be integrated to gain a complete and clinically relevant understanding of the neuroimmune regulatory function of acupuncture and its relationship with the neuroimmune mediators.
