TARIFNAME AYARLANABILIR YENI NESIL BAGLANMA DAYANIMI ÖRNEK HAZIRLAMA VE MAKASLAMA TEST APARATI Teknolojik Alan: Bu bulus, makaslama testlerinde materyal yüzeyine sabit yükün paralel uygulanmasi sonucunda materyalin kopma ve kirilmaya karsi olan direncinin ölçümünde kullanilan deney numunesinin hazirlanmasini saglayan ayarlanabilir yeni nesil baglanma dayanimi örnek hazirlama ve inakaslama test aparati ile ilgilidir. Teknigin Bilinen Durumu: Makaslama testleri genellikle materyalin yüzeyine paralel olarak uygulanan sabit bir yük altinda kopmaya-kirilmaya karsi direnme yetenegini ölçmek için gerçeklestirilir. Bu testin amaci, bir baglantidaki yapistiricinin performansini karsilastirmak ve mekanik tepkisini belirlemektir. Dental materyallerin birbirleriyle adezyonu ya da dis dokulari ile adezyonu dis hekimligi basarisinda önemli bir yer tutmaktadir. Kullanilacak olan dental materyalin adezyon kuvveti ve güvenilirliginin belirlenmesinde siklikla kullanilmaktadir. Dis hekimliginin Protetik Dis Tedavisi, Restoratif Dis Hekimligi, Pedodonti, Ortodonti, Endodonti gibi birçok bölümünde dental materyaller kullanilmaktadir. Dis hekimligi uzun dönem basarisinda ve daha az saglikli doku uzaklastirilmasi ve bununla birlikte koruyucu dis hekimligi açisindan da yeni nesil adeziv dental materyallerin önemi büyüktür. Bilgisayar destekli üretim ve diger alanlardaki hizla gelisen teknolojilerin dis hekimligine aktarilmasi ile birlikte büyük bir hizla yeni dental materyaller pazara sunulmaktadir. Bulus önerimiz dental materyaller üzerinde yapilacak makaslama baglanma dayanim testinde standardize ve hata payini en aza indirecek sekilde numune hazirlamak amaciyla kullanilacaktir. Yeni materyallerin baglanma dayaniminin degerlendirildigi test yöntemleri sinirlidir. Test yöntemleri içerisinde uygulama kolayligi, netligi, tekrarlanabilirliligi, kiyaslamasi ve maliyeti açisindan en fazla tercih edilen test metodu makaslama baglanma dayanim testleridir. US6308579B1 numarali patent basvurusunda "Yapisma mukavemeti olusturmak için aparat ve yöntemler" anlatilmaktadir. Mevcut bulus, bir yapistirici olusturmak ve yapistiriciyi bir test parçasina yapistirmak için aparat ve yöntemleri açiklamaktadir. Test parçasina baglanan silindirik sekilli bir yapistirici olusturmak için bir baglama ve kaliplama platformu, bag bölgesini test parçasi üzerindeki belirli bir alanla sinirlar. Baglama ve kaliplama platformu, büyük ölçüde silindirik sekilli ve alt tabakaya büyük ölçüde dik olan bir yapiskan olusturur. https://www.youtube.com/watch?v=2L00v2r7CwQ#action=share linkinde yer alan video yukaridaki basvuruya ait mekanizmanin uygulanisini göstermektedir. Yukarida kullanilan makaslama testi için numune hazirlama aparatinin uygulama esnasinda birçok zorluk ve dezavantaji vardir. Deney numunesinin hazirlanmasi esnasinda blok üzerindeki materyalin led isini ile polimerizasyon islemine tabi tutulmasi esnasinda, blogun üzerindeki jig parçasinin isik geçirme özelligi olmadigindan dolayi polimerizasyon homojen gerçeklesmemektedir. Mevcut jigin isik geçirgenligi kisitlidir. Seffaf yapida olmadigi için materyal içerisinde kalan hava bosluklari elimine edilememekte ve kontrolü saglanamamaktadir. Bu da numunenin testi esnasinda gerçekçi sonuçlar verememesine yol açacaktir. Ayrica polimerizasyon islemi sonrasinda numunenin çikartilmasi sirasinda uygulanan eksenel kuvvet baglanti mukavemetini etkilemektedir. Makaslama testinden önce mevcut jig, deney numunesinden ayrilirken iki materyal arasi baglanti zarar görmektedir. Sonuç olarak yukarida bahsedilen dezavantajlarin üstesinden gelebilen yeni bir teknolojiye ihtiyaç duyulmaktadir. Bulusun Tanimi: Bulus konusu sistemimizin saglamis oldugu avantajlardan birisi, numune hazirlama cihazimiz hiçbir sekilde deney numunesine zarar vermemektedir. Deney numunesinin polimerizasyon islemi tamamlandiktan sonra kaliplar birbirlerinden deney numunesine göre paralel (radyal) olarak ayrilmaktadir. Mevcut yöntemde bu durum numuneye göre eksenel (dik) olarak gerçeklesmektedir. Bu sayede deney numunesi üzerindeki materyal ve materyalin üzerine konumlandirildigi blok hiçbir sekilde hasar almamaktadir. Bu da kalibin hassasiyet ömrünü arttirmakta, bu sekilde kalibin daha fazla numune üzerinde kullanimini saglamaktadir. Bulus konusu sistemimizin bir diger avantaji kalip malzemesinin seffaf malzemeden imal edilmesidir. Led isininin polimerizasyon islemi sirasinda her yönde materyale ulasmasina izin verilerek, polimerizasyon isleminin sorunsuz ve homojen gerçeklesmesi saglanmaktadir. Ayrica deney yapan arastirmaci, deney düzenegini bozmadan polimerizasyon sonucunu kontrol edebilecek, hava bosluklari görülerek elimine edilebilecektir. Bulus konusu sistemimizi olusturan parçalar basit ve kullanisli yapiya sahip olmasi maliyetleri düsürmektedir. Ayrica bu parçalarin birbirlerine kolay bir sekilde monte edilebilmesi de personelin isini oldukça kolaylastirmaktadir. Kaliplarin birbirlerine geçmeli seklinde montajlanmasi, deney numunesinin hazirlanmasi esnasindaki islem süresini oldukça kisaltmakta ve çok sayida deney numunesinin hazirlanmasina zemin olusturmaktadir. Sekillerin Açiklanmasi: Bulus, ilisikteki sekillere atifta bulunularak anlatilacaktir, böylece bulusun özellikleri daha açikça anlasilacak ve takdir edilecektir, fakat bunun amaci bulusu bu belli düzenlemeler ile sinirlamak degildir. Tam tersine, bulusun ilisikteki istemler tarafindan tanimlandigi alani içine dahil edilebilecek bütün alternatifleri, degisiklikleri ve denkliklerinin kapsanmasi amaçlanmistir. Gösterilen ayrintilar, sadece mevcut bulusun tercih edilen düzenlemelerinin anlatimi amaciyla gösterildigi ve hem yöntemlerin sekillendirilmesinin, hem de bulusun kurallari ve kavramsal özelliklerinin en kullanisli ve kolay anlasilir tanimini saglamak amaciyla sunulduklari anlasilmalidir.

TR TR TR DESCRIPTION ADJUSTABLE NEW GENERATION BOND STRENGTH SAMPLE PREPARATION AND SHEAR TEST APPARATUS Technological Area: This invention is an adjustable new generation bond strength sample preparation and shear test apparatus that enables the preparation of the test sample used in the measurement of the material's resistance to rupture and fracture as a result of the parallel application of a constant load to the material surface in shear tests. It's about the apparatus. State of the Art: Shear tests are generally carried out to measure the ability of the material to resist breaking under a constant load applied parallel to its surface. The purpose of this test is to compare the performance of the adhesive in a joint and determine its mechanical response. The adhesion of dental materials with each other or with dental tissues has an important place in the success of dentistry. It is frequently used to determine the adhesion strength and reliability of the dental material to be used. Dental materials are used in many departments of dentistry such as Prosthodontics, Restorative Dentistry, Pedodontics, Orthodontics and Endodontics. New generation adhesive dental materials are of great importance in the long-term success of dentistry and in terms of the removal of less healthy tissue and preventive dentistry. With the transfer of rapidly developing technologies in computer-aided manufacturing and other fields to dentistry, new dental materials are being introduced to the market at a rapid pace. Our invention proposal will be used to prepare samples in a way that will standardize and minimize the margin of error in the shear bond strength test to be performed on dental materials. Testing methods to evaluate the bond strength of new materials are limited. Among the test methods, the most preferred test method in terms of ease of application, clarity, repeatability, comparison and cost are shear bond strength tests. In the patent application numbered US6308579B1, "Apparatus and methods for creating adhesion strength" are described. The present invention discloses apparatus and methods for forming an adhesive and adhering the adhesive to a test piece. To create a cylindrical shaped adhesive that bonds to the test piece, a bonding and molding platform restricts the bond region to a specific area on the test piece. The bonding and molding platform forms an adhesive that is substantially cylindrical in shape and substantially perpendicular to the substrate. The video at the link https://www.youtube.com/watch?v=2L00v2r7CwQ#action=share shows the implementation of the above application mechanism. The sample preparation apparatus for shear testing used above has many difficulties and disadvantages during application. During the preparation of the test sample, while the material on the block is subjected to polymerization with LED light, the polymerization does not occur homogeneously because the jig part on the block does not have the ability to transmit light. The light transmittance of the existing jig is limited. Since it is not transparent, air gaps within the material cannot be eliminated and controlled. This will cause the sample not to provide realistic results during testing. In addition, the axial force applied during the removal of the sample after the polymerization process affects the connection strength. Before the shear test, when the existing jig is separated from the test sample, the connection between the two materials is damaged. As a result, a new technology is needed that can overcome the disadvantages mentioned above. Description of the Invention: One of the advantages of our inventive system is that our sample preparation device does not damage the test sample in any way. After the polymerization process of the test sample is completed, the molds are separated from each other parallel (radial) according to the test sample. In the current method, this occurs axially (perpendicularly) relative to the sample. In this way, the material on the test sample and the block on which the material is positioned are not damaged in any way. This increases the precision life of the mold, thus allowing the mold to be used on more samples. Another advantage of our inventive system is that the mold material is manufactured from transparent material. By allowing the LED beam to reach the material in all directions during the polymerization process, the polymerization process is ensured to occur smoothly and homogeneously. In addition, the researcher conducting the experiment will be able to control the polymerization result without disrupting the experimental setup, and air gaps will be visible and eliminated. The parts that make up our inventive system have a simple and useful structure, reducing costs. In addition, the easy assembly of these parts to each other makes the work of the personnel much easier. Assembling the molds interlockingly shortens the processing time during the preparation of the test sample and provides the basis for the preparation of a large number of test samples. Description of Drawings: The invention will be described with reference to the accompanying drawings, so that the features of the invention will be more clearly understood and appreciated, but the purpose of this is not to limit the invention to these particular embodiments. On the contrary, it is intended to cover all alternatives, modifications and equivalences of the invention that may be included within the scope of the invention as defined by the appended claims.
