Axial strengths of foil, all-ceramic and PFM molar crowns

Metal‐Ceramic Interface Evaluation of a Gold‐Infiltrated Alloy

“…In an effort to eliminate the time‐consuming casting process and also to produce a thinner metal core to optimize esthetics, various foil systems have been developed over the years. Some product examples have included Renaissance (or Ceplatec in Europe), Sunrise, Plati‐deck, and Flexobond crowns; 5–8 however, due to poor short‐term clinical data and mechanical properties, these systems fell out of favor. Captek (Precious Chemicals Company Inc., Altamonte Springs, FL) is the latest in the advancement of noncast metal substructure systems by employing capillary attraction to flow nearly pure gold into a high‐noble metal 3D capillary network to produce a composite metal alloy substructure.…”

Comparison of Stresses Generated within the Supporting Structures of Mandibular Second Molars Restored with Different Crown Materials: 3‐D Finite Element Analysis (FEA)

“…Several prior studies investigated stress distributions within the crown materials . These studies concentrated on the fracture strength of all‐ceramic restorations compared to ceramo‐metallic restorations . However, no estimation of the stresses transmitted through different crown restorative materials to the supporting periodontal tissues and alveolar bone structure during function is available.…”

Flexural strength of two electro-plated dental ceramics

“…Reinforcement with a metal coping in the form of a metal-ceramic full-coverage restoration is today stil L the commonest technique. Other methods include the placement of a metallic foil, as for the Ceplatec system, or electro-plating of the ceramic material with a thin (=-100-200 pm) metallic layer (5)(6)(7). In this manner the importance of porosities, flaws.…”
