Direct composite fillings in the posterior region. A case history using a nanohybrid composite

چکیده
30 INTERNATIONAL DENTISTRY – AUSTRALASIAN EDITION VOL. 7, NO. 2 Nanotechnology, on the other hand, has made successful inroads into modern composite technology and continues to be the subject of considerable research work1,12,13. Nanosized inorganic fillers enable the filler content of composite pastes to be maximised while retaining excellent clinical handling properties and at the same time minimising the percentage of organic resin matrix. This results in dental filling composites with greatly improved mechanical properties14,15.

Cusp replacement with an extensive posterior direct restoration using a nanohybrid bulk - fill ormocer
Today, direct composite restorations in posterior teeth are a part of the standard therapy spectrum in modern dentistry. The performance of this treatment method in the masticatory load-bearing posterior region has been conclusively proven in many clinical studies, even for extensive composite restorations with cuspal coverage. These restorations are usually carried out in an elaborate incremen...
متن کاملLongevity of dental amalgam in comparison to composite materials
HEALTH POLITICAL BACKGROUND Caries is one of the most prevalent diseases worldwide. For (direct) restaurations of carious lesions, tooth-coloured composite materials are increasingly used. The compulsory health insurance pays for composite fillings in front teeth; in posterior teeth, patients have to bear the extra cost. SCIENTIFIC BACKGROUND Amalgam is an alloy of mercury and other metals an...
متن کاملComparative Evaluation of microleakage of Bulk-fill and Posterior Composite Resins Using the Incremental Technique and a Liner in Cl II Restorations
Background and Aim: In recent years there has been a surge in the use of tooth-colored restorations. However, the polymerization shrinkage of these materials can form gaps, resulting in microleakage. This study aimed to compare microleakage by using different materials and techniques. Materials and Methods: In this experimental study, Cl II cavities were prepared on the mesial surfaces of 60 s...
متن کاملThe Properties and Selection of Posterior Direct Restorations
Early tooth-colored restorative materials were weak and only suitable for anterior teeth. Over time, composites were developed that offered improved properties enabling their use in posterior teeth where subject to occlusal loading and forces of mastication. Secondary caries is the main reason for failure of both amalgam and composite restorations. Amalgam restorations offer ease-of-use but poo...
