When considering immediate im- plant placement with an immediate loading procedure, careful patient screening and selection are required. Smoking The literature reports lower survival rates of dental im- plants in smokers. One possible mechanism that might affect osseointegration in smokers is a lowering of the blood flow rate due to increased peripheral resistance and platelet aggregation. Tobacco directly affects osteo- blast function. In general, smoking is a major risk factor for implant failure. If smokers are treated with implants, good bone quality is necessary. In the presented cases, bone quality was good and no augmentation procedures were needed. In all cases, ex- cellent primary stability was achieved. Based on the out- comes of the present report, it can be concluded that immediate implant placement with immediate loading in heavy smokers can lead to good results if the surgeon has a great deal of expe rience in placing implants and the patient’s bone quality is good enough. T.A.G. implants The surface finish of all implants is achieved mechanically and chemically by blasting with particles and acid etching, with a roughness ranging from 1.8 µ to 2.2 µ and morphol- ogy of the cavities from 2 µ to 40 µ. The micro-surface mor- phology increases bone-to-implant contact and results in an improvement of mechanical anchorage for better pri- mary stability that favours cellular adhesion. Our SEM ex- aminations confirmed the accurate surface structure of the implants used. The implant concept, such as macro- design geometry and micro-surface quality, will deter- mine tissue reaction and influence the clinical success of the dental implant in the long term. The macro-geometry of T.A.G. implants is designed to increase the overall functional surface area, contribut- ing to a favourable force distribution that decreases the effective stress. The implant geometry and macro-po- rous surface (mm–40 µ) play a role in the primary stabil- ity and long-term mechanical fixation. Parameters such as thread form, helix angle, lead number, width, depth, pitch and body shape have been the subject of intensive research regarding T.A.G. implants. Integration and opti- misation of all these variables will lead to a better implant design. In the case of immediate loading, these param- eters are critical. Since the implant surface is the first component to in- teract with the host, surface modifications of T.A.G. im- plants have been extensively investigated in an attempt to increase the rate of bone healing and thereby allow prac- titioners to perform immediate or early loading of den- tal implants. The new generation of implants developed by T.A.G. Medical Products in Israel optimises the differ- ent parameters, such as geometry, topography, surface properties and surface quality, that lead to high success rates. The main advantage in using T.A.G. implants is the uniform connection design. That means that the 2.44 mm internal hexagonal connection is the same for all of the implants, ranging from 3.3 to 6.0 mm in diameter, sim- plifying the surgical process and eliminating the need to stock different restorative options to accommodate dif- ferent implant sizes. contact Dr Dr Branislav Fatori Rolandstraße 11 45128 Essen, Germany Tel.: +49 201 82188890 info@fatori.de www.fatori.de Dr Inge Schmitz Georgius Agricola Stiftung Ruhr Institute for Pathology Ruhr-University Bochum Bürkle-de-la-Camp-Platz 1 44789 Bochum, Germany Inge.Schmitz@rub.de Author details Author details 1 2018 15
