British Dental Journal, 2018 Objectives: To determine the degree of taper and the average angle of convergence (AOC) accomplished for full veneer/coverage crowns (FVC) by supervised undergraduate students at a dental teaching hospital. Methods One hundred and twenty-five stone dies of FVC preparations (25 full-metal [FMCs] and 100 metal-ceramic [MCCs]), prepared by dental ...

The convergence angle in 478 full crown preparations was assessed. Of these preparations, 351 had been performed by general practitioners and 127 by dental students. Groups of preparations performed on incisors, premolars, and molars were compared, as were preparations performed by dentists and students.

Porcelain-veneered full-crown restorations made with cadmium patterns
The Journal of Prosthetic Dentistry, 1967Abstract A technique with cadmium for direct metal patterns has been described. Previously, the use of this technique was limited to full gold crowns and acrylic resin veneer crowns. Clinical experience has shown that it can be used for making porcelain fused-to-metal restorations.

Fracture strength of full-contoured ceramic crowns and porcelain-veneered crowns of ceramic copings
The Journal of Prosthetic Dentistry, 1994This is vitro study compared the fracture strength of Dicor ceramic crowns with a 1 mm axial wall thickness and a 2 mm occlusal thickness with Dicor copings veneered with Vitadur-N or Dicor-Plus porcelain to create similar contours. Tooth preparations for complete crowns were made on human molars with a 10-degree total convergence and a 1 mm shoulder ...

Tissue management for full cast veneer crowns
The Journal of Prosthetic Dentistry, 1965Abstract The relationship between the tooth and its investing and environmental tissues has been discussed. Three important relationships of the tooth and the tissues are as follows: (1) attachment of the gingiva to the tooth occurs at the cementoenamel junction, (2) the cervical ridge of the enamel flares out forming a convexity under which the free

Effect of Preparation Surface Area on the Clinical Outcome of Full Veneer Crowns in Dogs
Journal of Veterinary Dentistry, 2014Crown therapy is commonly used in veterinary medicine to provide support to teeth which have previously fractured, received root canal therapy, have significant wear, or experienced other detrimental removal of tooth substance. As with several aspects of veterinary medicine, many of the recommendations or guidelines for crown therapy originate from ...

Solving the problems of cementing the full veneer cast gold crown
The Journal of Prosthetic Dentistry, 1966Abstract Tests were performed to indicate the accuracy with which full crowns can be cemented on prepared teeth. Findings indicated that using both internal relief for cement, plus a vent for escape of cement permitted a minimal gingival discrepancy following cementation. This discrepancy may be compensated for by constructing the crown with a slight
