How are fixed prosthodontic restorations held in place?

Question

Quizplus · Accepted Answer

Fixed prosthodontic restorations, such as crowns and bridges, are typically held in place with permanent cementation. This allows for a strong and durable bond between the restoration and the tooth, while still allowing for easy removal by a dental professional if necessary. Mechanical retention, such as using pins or screws, is sometimes used but is less common than cementation. Temporary cementation may be used during the fitting process but is not a permanent solution.
