Metal‐Ceramic Interface Evaluation of a Gold‐Infiltrated Alloy

Abstract

Microscopy and XRD analysis showed that micromechanical interlocking is the primary mechanism of porcelain adherence to Captek metal. The use of Capbond prior to porcelain application to Captek results in gold nodules on the surface to aid retention. Existing metal-ceramic bond compatibility standardized tests are not sufficient for evaluating Captek, primarily due to the flexibility of the material.

Relationship of Margin Design for Fiber-Reinforced Composite Crowns to Compressive Fracture Resistance

“…Metal ceramic restorations continue to be a popular option for fixed prosthodontics, based on their clinical longevity and acceptable esthetics 1 . Recently, concern has been expressed regarding corrosion of metal alloys and unwanted allergic or toxic side effects affecting some patients and laboratory personnel 2,3 .…”

“…Metal ceramic restorations continue to be a popular option for fixed prosthodontics, based on their clinical longevity and acceptable esthetics. 1 Recently, concern has been expressed regarding corrosion of metal alloys and unwanted allergic or toxic side effects affecting some patients and laboratory personnel. 2,3 Moreover, the artifacts on magnetic resonance tomography (MRT) and computer tomography (CT) caused by metal and alloy may result in attenuation of signal intensity, image distortion, and signal loss, which severely influence image quality.…”

Precious metal alloys for dental applications

“…The manufacturer also claims the lack of oxides and a burnished fi t resulting in extremely small marginal gap sizes account for excellent gingival tissue health adjacent to the restoration. Because of the lack of oxide, a mechanical ceramo-metal bond is developed by infi ltrating a porcelain bonder of gold with platinum microfi laments, creating a roughened surface (Vasani et al , 2009). The underlying gold color gives an esthetic appearance, as opaque porcelains are not needed to mask an oxide layer.…”

Processing and properties of pressable ceramic with non-uniform reinforcement for selective-toughening

“…A strong interface between brittle ceramic-matrix and ductile metal reinforcements is essential for nearly all ceramic/metal composites [1][2][3][4][5][6][7][8][9][10], particularly if strength improvement is required besides toughness enhancement. A weak ceramic/metal interface is conditionally desirable for the pull-out and frictionalsliding toughening mechanisms, important to crack-bridging [11,12], but should generally be avoided if long-term reliability, environmental influence, surface contact and wear resistance, important to many bio-materials and industrial applications, are key concerns to the design and processing of a metal reinforced ceramic-matrix composite.…”
