Abstract: The use of resin composite for routine restoration of cavities in posterior teeth is now commonplace, and will increase further following the Minamata Agreement and patient requests for tooth-coloured restorations in their posterior teeth. It is therefore relevant to evaluate the published survival rates of such restorations. A Medline search identified 144 possible studies, this being reduced to 24 when inclusion criteria were introduced. Of these, ten directly compared amalgam and composite, eight were cohort studies, and six were systematic reviews. It was concluded that posterior composites may provide restorations of satisfactory longevity and with survival rates generally similar to those published on amalgam restorations. However, the ability of the operator in placing the restoration may have a profound effect.

Clinical relevance: With the increasing use of composite for restorations in posterior teeth, it is relevant to note that these may provide good rates for survival.

During this webinar Eoin O’Sullivan will take you through his personal journey with digital scanning, explaining how he found himself in a dilemma when he had to replace his first iTero, after he had assumed that the scanner’s capabilities would transition to focus on orthodontics when it was bought out by Align Technology in March 2011. He will share his thoughts about which scanner would best suit his restorative practice, and why he opted for the next generation of iTero over all the other scanners on the market.
