Purpose:
To evaluate the effect of the triad finish line design, axial wall convergence angle, and luting cement on the marginal fit of metal copings used in metal-ceramic crowns.
Materials and methods:
Schematic dies and their respective copings were cast in NiCr alloy. The dies exhibited the following finish line/convergence angle combinations...
This study evaluated the shear bond strength of different repair systems to nickel-chromium (NiCr) alloy after storage in water for either 24 hours or six months. One hundred cylindrical specimens (3 mm thick x 9 mm diameter) were fabricated using an NiCr alloy and embedded in a PVC ring, where they received one of five bonding and resin composite...
A strong and durable bond between a metal framework and a resin-based luting agent is desired. Metal primers have been shown to be very effective on noble alloys. However, there is insufficient information about their effect on base metals.
The purpose of this study was to evaluate the effect of metal primers on the shear bond strength of resin cem...

... Several studies indicated that poor marginal adaptation, sub-gingival margin placement, and over-contoured crowns have the possibility of contributing to localized periodontal inflammation. 14,15 Clinical experiences have shown that if one of the abutments of a fixed partial denture fails, the whole prosthesis fails often with the loss of the abutment tooth and resulting in a destructive clinical outcome. 16 Many studies have been conducted trying to determine the possible methods for increasing the success rate of resin retained bridge while preserving the periodontal health of the abutment. ...

... Higher bond strengths between metal and resin have been reported if the metal is pretreated with silica. 80,81 Alternatively, alloy primers can create a direct chemical bond between metals and resin, without the need for any silicatization. These primers contain carboxylic or phosphoric acid functional monomers which react with oxides present on the metal surface. ...

... En odontología, se utilizan imprimaciones metálicas con el objetivo de que exista una fuerte unión entre los materiales de resina y las aleaciones metálicas. Estas imprimaciones contienen monómeros activos, las cuales pueden ser MDP (10metacriloxidecrilo dihidrogenofosfato) o MEPS (metacrilato de tiofosfato) que se encargan de beneficiar la unión química entre estos materiales 15,16 . ...
