DİŞ HEKİMLİĞİ RESTORATİF UYGULAMALARINDA YENİ MATERYAL OLARAK CAM KARBOMER SİMANLAR

Özellikle son 20 yıl içerisinde, mükemmel restoratif dolgu materyali için arayışlar hızla devam etmektedir. Kompozitlerdeki sınırsız doldurucu reaksiyonları, kompozitin rezin içeriğindeki vazgeçilmez büzülme fenomenini etkileyememektedir. Bu sebeple, cam iyonomerlere olan özlem, modifiye materyallerin oluşturulmasıyla sağlanmaya çalışılmaktadır. Bununla beraber, cam iyonomerlerin önlenemeyen renk uyumsuzluğu, dirençlerinin ve bağlanma-ikincil çürük önleme özelliklerinin artırılmasıyla telafi edilmeye çalışılmıştır. Cam iyonomerler, mine ve dentine kimyasal bağlanmaları, devam eden flor salınımı ve klinik koşullar altında büzülme göstermemeleriyle bilinirler. Düşük seviyedeki mekanik özellikler, konvansiyonel cam iyonomer simanları yüksek stress taşıyan alanlarda kullanımlarını elverişsiz hale getirmiştir. Materyalin direnç arayışı, yeni formülasyonlar ve sertleştirme tekniklerini de beraberinde getirmeye başlamıştır. Son yıllarda piyasaya sürülmeye başlanan cam karbomer simanlar bu arayışın zorunlu bir sonucu olarak ortaya çıkmaktadır. Karbomer ve floroapatitle güçlendirilmiş materyalin orta ve uzun dönemde ümit vaat edeceği açıktır. Anahtar Kelimeler: Cam karbomer siman, cam iyonomer siman, karbomer, floroapatiti GLASS CARBOMER CEMENTS AS A NEW MATERIAL IN RESTORATIVE DENTISTRY PRACTICEABSTRACT For recent 20 years there has been a big effort to find a perfect restorative material. The particul-filler-reac tions within the contemporary composite technology could never totally eliminate the indispansible shrinkage problem of composites developed. For this reason the demand for glass ionomer materials try to cover for with producing new modified materials instead of composites. On the other hand, it has been tried to compansate of the color mismatch and solubility of glass ionomers via the increasing of the properties of chemical bonding and strength of the materials. The glass ionomer materials are known as having the specific properties including chemically bonding to enamel and dentin, continuing release fluoride, and non-contruction at clinical conditions. Due to their low physical properties glass ionomers are not suitable for high stress area. By the way, to find the new strenghtened materials, it has been started to study for new formulations and curing techniques. Recently, the new materials –glass carbomers- has been evoked due to this demand. It is clear that the material strengthed by fluoroapatite and carbomer will be so hopefull for a long time. Keywords: glass carbomer cement, glass ionomer cement, carbomer, floropatit

Anahtar Kelimeler:

Cam karbomer siman, cam iyonomer siman, karbomer
