Marginal Strength of Collarless Metal Ceramic Crown
Metal ceramic restorations have been implicated for the discoloration in area of labiogingivalmargin. Attempts to rectify this, by altering the design of metal frameworkswill lead to decrease in fracture strength atmargin. This in vitro study compared the fracture strength at margins of metal ceramic crowns cemented to metal tooth analogs. Crowns evaluated with different marginal configurations...
متن کاملComparison of Marginal Fit between Collarless Metal Ceramic and two all Ceramic Restorations
Marginal adaptation of the crown is a crucial factor in determining its clinical acceptability. Crown fit as judged by marginal seal influences the longevity of the cast restorations to a great extent. Metal ceramic restorations have been implicated for the discoloration in area of labio-gingival margin. Attempts to rectify this, by altering the design of metal frame works as eliminating the la...
متن کاملEffect of metal design and technique on the marginal characteristics of the collarless metal ceramic restoration.
This investigation examined the marginal characteristics of the collarless metal ceramic restoration made with two commonly used direct-lift techniques: (1) a porcelain/wax paste and (2) a porcelain/liquid slurry. The metal copings touched the shoulder in half of the groups and were left 0.5 mm short in the other half to comprise the four experimental groups. Marginal seal was evaluated at faci...
متن کاملA study on the fracture strength of collarless metal-ceramic fixed partial dentures
PURPOSE The objective of this study was to evaluate fracture strength of collarless metal-ceramic FPDs according to their metal coping designs. MATERIALS AND METHODS Four different facial margin design groups were investigated. Group A was a coping with a thin facial metal collar, group B was a collarless coping with its facial metal to the shoulder, group C was a collarless coping with its f...
متن کاملCollarless metal ceramic fixed partial denture: a clinical report.
A case of a collarless metal ceramic fixed partial denture with preparations made at a slightly supragingival level is reported. The absence of the metal collar in the buccal portion of the abutments provides an excellent esthetic appearance. The use of a collarless metal ceramic fixed partial denture is a viable approach for restoring dentition where the esthetic quality is the primary concern.
