Anatomical zirconia teeth

The teeth are made of anatomically dry milled zirconia, in groups of 3-4 elements.

The patient presented for prosthetic restoration of both arches with masticatory, phonic and physiognomic dysfunctions.

The patient accused as unsatisfactory the dental therapeutic solutions applied in the past and the recurrent removal of an old acrylic work, inadequately adapted.

The treatment plan proposed and carried out consisted of vital extirpations of all remaining teeth, zirconium coronal root reconstruction and restoration of prosthetic abutments.

The chosen crowns were anatomical zirconia teeth.

Types of dental crowns

Depending on the material from which they are made, dental crowns can be made of:

  • ceramic (porcelain)
  • metal-ceramic
  • metal-ceramic semi-physiognomic
  • metal
  • acrylic
  • metal-acrylic physiognomic
  • metal-acrylic semi-physical
  • integral zirconium
  • zirconium-porcelain (ceramic)

Each category is accompanied by certain specifications as well as sub-categories. Thus zirconium porcelain teeth are distinguished by the fact that they are best tolerated by the body, are biologically inert and have a degree of translucency similar to natural teeth, making them indistinguishable from them.

Zirconium porcelain teeth have in turn 3 subcategories, depending on the thickness of the ceramic and zirconium layers:

  • Economical Line (Eco Line) zirconium teeth
  • Multilayer zirconium teeth
  • Anatomic zirconia teeth

After being presented with the available dental crown models, the patient chose anatomic zirconia porcelain teeth.

Advantages compared to other types of dental crowns:

  • Superior strength to other crown types.
  • The only type of crown that provides a natural look to the teeth, guaranteeing superior aesthetics to other crown types.
  • High tolerance to tooth tissue compared to that offered by metal-ceramic and metal crowns.
  • Impeccable adaptation to the tooth structure due to the technology used for their construction, which is based on scanning the dental impression and milling the zirconia, rather than the casting used for metal crowns.
  • Translucency, light penetrates through the porcelain and zirconium layers similar to the way it penetrates through natural teeth (enamel, dentin).
  • Lack of thermal conductivity which means no more tooth sensitivity triggered by heat or cold.
  • Reduced food retention compared to other types of crowns.
  • Easier hygienisation.
  • Presence of less allergen than in other types of crowns.
  • Tooth longevity.

For the case illustrated above, the cementing of dental crowns was done with Keac Cem Plus.

The execution time was 3 weeks and the evolution is very good, with no problems being observed after the cementation.
