What type of provisional could be selected for anterior teeth?

Preformed polycarbonate
Metal crown
Porcelain veneer
Composite resin

The correct answer is: Preformed polycarbonate

The most suitable option for anterior teeth would be a preformed polycarbonate provisional. Preformed polycarbonate crowns are specifically designed for use as temporary crowns for anterior teeth due to their ability to closely mimic the natural shape and color of the tooth. Metal crowns are typically used for posterior teeth and may not provide the desired aesthetics for anterior teeth. Porcelain veneers are a permanent restorative option and are not typically used as a provisional. Composite resin can be used as a provisional, but they are not as strong or durable as preformed polycarbonate crowns, making them less ideal for anterior teeth.
