    Study Notes

    Dental Crown Restoration

    • Crowns are used to restore badly broken, worn, or fractured teeth, improve aesthetics, and maintain structural stability.
    • Recent literature shows no strong evidence that crowns are better than other restorations for root-filled teeth.
    • Clinical stages of dental crown provision include assessment, choice of restoration, tooth preparation, construction and fit of temporary restoration, tooth preparation impressions, fit of definitive restoration, short-term follow up, and long-term follow up.
    • Assessment factors include patient, biological, and aesthetic factors.
    • Crown restoration choices include full crowns, 3/4 and 7/8 crowns, and materials like metal, metal-ceramic, and full ceramic crowns.
    • 3/4 and 7/8 crowns are a hybrid between an onlay and a full crown, but are not commonly prescribed due to technical difficulties and poor patient acceptability.
    • Full metal crowns are entirely cast in a metal alloy, with noble and high-noble alloys generally based on gold.
    • Gold crowns are indicated for posterior teeth due to aesthetic reasons and have good wear properties and dimensional accuracy.
    • Palladium-based alloys were introduced as a cheaper alternative to gold alloys in the 1970s and have a silverish appearance.
    • Base-metal alloys are rarely used to make full metal crowns and are more commonly used as part of metal-ceramic crowns as bonding alloys.
    • Titanium and titanium alloys are highly biocompatible and are used in dentistry.
    • Dental crown restoration involves a thorough and targeted patient history and clinical dental examination to ensure optimum condition and longevity for the proposed crowns.
