# Denture materials: Titanium, Zirconia...
Chromium-Cobalt (CrCo) :
Cobalt-chromium is perfectly suited to dental prosthetics thanks to its hardness coupled with its elasticity, which is twice that of precious metal alloys.
It is therefore particularly recommended for the manufacture of single-unit chassis and long-span bridges.
This material, specially adapted to dental applications, is a beryllium- and nickel-free alloy based on cobalt and chromium. We use it in the machining and laser sintering process in powder form - the same material as in casting, but the result is a perfectly homogeneous metal structure with a much longer service life.
We use it for laser sintering and milling.
Titanium :
Titanium (Ti) dental material is widely used in dental prosthetics for its physico-chemical properties, which are well suited to clinical use: biocompatibility, good corrosion resistance, low density (lightweight material), mechanical strength, radiopacity. It is the most widely used material for dental implants in particular.
Although less frequently chosen than precious or non-precious alloys (nickel-chromium or cobalt-chromium), titanium nevertheless represents an alternative for the manufacture of frameworks for single or multiple fixed prostheses.
We use it for laser sintering and milling.
Benefits for patients:
- No metallic taste sensation in the mouth
- Titanium's low thermal conductivity avoids unpleasant sensations of cold or heat.
- Its excellent X-ray transparency facilitates diagnosis and inspection in the dental practice.
Zirconia :
Zirconia is the aesthetic material of choice for full ceramic crowns, copings, inlays, bars and 16-unit bridges. Zirconia offers excellent biocompatibility. Aesthetically, zirconia crowns have the advantage of looking more natural. Its color remains durable and unchanged over the years. It also offers excellent translucency, for a perfect aesthetic appearance. Zirconia is also a robust and resistant material.
One of Dent All Group's strengths is to offer you 3D zirconia. This special zirconia enables us to offer you, in addition to gradations in shade, gradations in hardness and gradations in translucency (3D for 3 gradations).
Depending on how the framework is machined, hardness levels of up to 650 MPa can be achieved in the incisal area and 1200 MPa in the cervical area.
Of course, this dental material is available in all 16 Vita shades.
Dent All Group's expertise lies in placing the designs in the disc in such a way as to achieve the optimum combination of stability and aesthetics.
We only use zirconia for milling.
Ceramic block, hybrid etc... :
Ceramic has an impeccable aesthetic effect, being similar to tooth enamel. It is therefore able to imitate natural teeth perfectly. In terms of shade and transparency, restorations are more transparent, and therefore incompatible for those with gray teeth.
Ceramic remains a lightweight, biocompatible dental restoration material.
On the other hand, this dental material can have a number of drawbacks, notably its resistance, which is why it is contraindicated for people suffering from bruxism.
It is more suitable for anterior restorations and less so for posterior restorations.
Ceramic is the material of choice for veneer-type restorations.
Lithium disilicate
Thanks to its high fracture strength (400 MPa) and optical properties similar to those of natural tooth structure, lithium disilicate is without doubt one of the most aesthetically pleasing materials for prosthetic restorations. We use Ivoclar E.Max, for example.
Nano or hybrid ceramics
Composed of ceramic and polymer, nano-ceramic is perfect for solid prosthetic restorations, while at the same time having an abrasion coefficient close to that of natural teeth.
Like zirconia, ceramic is only used in millingtechnique.
Resin (PMMA) :
PMMA can be used for both abutments and crowns. Thanks to its translucency, it is aesthetically pleasing and color-stable over time, meaning that prosthetic restorations can remain beautiful for years.
It also offers numerous functional advantages. PMMA fits precisely. It is a highly resistant material that can be repaired directly in the mouth if damaged.
PMMA is the dental material of choice for temporary restorations.
We also offer Graphene-reinforced PMMA for permanent restorations.
Peek & Acetal:
PEEK - short for polyetheretherketone - is a relatively new material.
Particularly resistant, it is insensitive to almost all organic and inorganic chemicals and to high-energy electromagnetic waves (such as X-rays). It is also highly resistant to wear and corrosion.
With its low density, Peek has an elasticity modulus similar to the human skeleton.
One of its assets is its high biocompatibility. Peek is the perfect alternative for metal allergies.
Moreover, its low hardness does not harm the original teeth. The smoothly polished surface makes it less susceptible to discoloration and hardly allows dental plaque to form. It's also a material that's easy to clean.
