Fixed prosthodontics is concerned with restoring teeth using restorations that are fixed into the patient's mouth. They are typically made in a laboratory after taking impressions (moulds) for the technician to work with. They are also known as 'indirect restorations'.
Indirect restorations can be used to restore and repair single or multiple teeth, and can be used to restore relatively small spaces between the teeth. Indirect restorations are more resistant compared to direct restorations of composite resin. Often indirect restorations may be indicated for reasons of improving aesthetic situations. It's hard to say how long fixed prosthesis should last, but when well planned, performed and properly maintained, they can last 10-12 years or more. The main types of indirect restoration are presented below:
