Nanohybrid and microfilled composite resin in Class II restoration of permanent molar teeth

Abstract

The aim of this study was to compare the clinical performance of nanohybrid composite resin in Class II restorations placed with a one-step self-etch adhesive with that of microfilled composite resin of permanent posterior molar teeth. A total of 100 participants who received Class II restorations either with nanohybrid composite resin bonded with a single step self-etch adhesive or conventional microfilled composite bonded with a single step self-etch adhesive. All restorations were evaluated by using slightly modified USPHS criteria at baseline and after 3, 6 and 12 months. The results revealed that nanohybrid composite resin showed better clinical outcome than that of the conventional microfilled composite resin restorations in respect to retention and marginal adaptation at 12 months observation period. It can be concluded that nanohybrid is superior to conventional microfilled composite resin in respect to retention, and marginal adaptation of Class II restorations of permanent molar teeth.

Polymer-Based Nanocomposite Coating Methods: A Review

“…Incorporating conductive fillers (such as conductive polymers, metals, and metal oxides) into polymer matrices, for example, makes it easier to form an oxide passive layer at the metal-coating interface, which serves as a secondary barrier and improves PNC corrosion resistance. A new system has been introduced by Ali et al, modified nanohybrid composite resin bonded with a one step selfetching bonding system and was compared to the conventional microfilled composite resin bonded with a one step-etching bonding system [229].…”

Son 10 Yılda Kompozit Rezin Restorasyonlar: İn Vivo ve İn Vitro Çalışmalarla Bir Derleme

“…41 Sınıf II restorasyonlarda yapılan bir çalışmada retansiyon ve marjinal adaptasyon bakımından nanohibrit kompozit rezinler mikrofil kompozit rezinlerden üstün bulunmuştur. 93 Teknolojideki gelişmelerle birlikte smart kompozitler adı altında kendini onarabilen kompozit rezinler, ACP (Amorf Kalsiyum Fosfat) bazlı kompozit rezinler, antimikrobiyal kompozit rezinler üretilmiştir. ACP bazlı kompozit rezinler ağız boşluğunda kalsiyum ve fosfat salarak apatit oluşumunu tetikler fakat polimerizasyon büzülmesinin fazla olması ve mekanik özelliklerinin yetersiz oluşundan dolayı geliştirilmesi gerekmektedir.…”
