Fear of an artificial, nonphysiomic appearance of the teeth after crown coating is one of the important reasons why, in general, the treatment of the front teeth is delayed.
"Let's not see that I have put my teeth" is a sympathetic, but also realistic, wish of the patients, who want the new crowns to align better in the dental arches, both in shape and texture and color.
Currently, metal crowns with acrylate or composite facets are considered compromise options for prosthetic teeth reconstruction. The presence of the metal confers an unsightly appearance, of "black streak" at the gum level, and over time there is a migration of the metal ions into the gingival tissue ("gingival tattoo") that accentuates the dark color, its vein. In addition, materials such as acrylate and composite age, change their color and "wash" from the metal infrastructure, which becomes visible.
Dental aesthetics, modern concept
Modern dental medicine has introduced a new concept in current practice, that of dental aesthetics. Therefore, now physicians are concerned not only with the functional restoration of the tooth, but also with the satisfaction of the aesthetic requirements, which have become more and more frequent. The dental technique laboratory does not execute a serial work, but a unique medical act, personalized and even artistic, because the prosthetic parts must fit perfectly into the harmony of the natural teeth, sowing them both in shape, color, as well as in transparency, translucency. , surface texture, light reflection, etc. Usually, any prosthetic work goes through several stages, which is verified intraoral, and the patient can express his opinion, wishes and demands related to it, so that the final result is an excellent one.
Dental crowns with excellent physiognomy: zirconium and integral ceramics
The stars regarding the choice of materials for dental crowns are undoubtedly ceramics and zirconia.
The fully ceramic crowns are absolutely enchanting due to the beauty of the material, the symbiosis between color and texture and the resemblance to natural teeth. The translucency and transparency are excellent, but the fragility of this material makes it suitable for front teeth restorations only.
The ceramic crowns on zirconium combine the beauty with the resistance in time of the infrastructure, which is why they have become the best options for the restoration of the lateral teeth (molars and premolars), but also for the frontal ones. In this way, the aesthetic demands of color, translucency, transparency, surface texture, but also the need for resistance to masticatory forces are met. In this way, the shortcomings of the presence of metal and those of acrylic and composite materials are eliminated.
