Clinical Performance of Short-fiber-reinforced Resin Composite Restorations vs Resin Composite Onlay Restorations in Complex Cavities of Molars (Randomized Clinical Trial)

Microleakage in combined amalgam/composite resin restorations in MOD cavities

Aim: To compare marginal seal at tooth-material and material-material interfaces in the proximal box in combined amalgam/composite resin restorations. Methods: Mesio-occlusal-distal (MOD) cavities were prepared in 35 premolars and permanent molars with carbide bur. The distal proximal box was restored with amalgam (Permite, SDI) until reaching the height of pulpal floor. Dental tissues were etc...

Continuous-fiber preform reinforcement of dental resin composite restorations.

OBJECTIVES Direct-filling resin composites are used in relatively small restorations and are not recommended for large restorations with severe occlusal-stresses. The aim of this study was to reinforce composites with fiber preforms, and to investigate the effects of layer thickness and configurations on composite properties. It was hypothesized that fiber preforms would significantly increase ...

A 3-year randomized clinical trial evaluating two different bonded posterior restorations: Amalgam versus resin composite

OBJECTIVE To compare the performance and postoperative sensitivity of a posterior resin composite with that of bonded amalgam in 40 (n = 20) large sized cavities and to evaluate whether resin composite could be an alternative for bonded amalgam. MATERIALS AND METHODS This was a randomized clinical trial. Twenty patients in need of at least two posterior restorations were recruited. Authors ra...

Fiber-reinforced onlay composite resin restoration: a case report.

AIM The purpose of this case report is to describe the clinical procedure for fabricating fiber-reinforced composite (FRC) onlay composite resin restorations using a FRC as the substructure. BACKGROUND A variety of therapeutic modalities are available to restore teeth with moderate coronal defects in the posterior region of the mouth. For patients who refuse complete crown restorations or whe...
