Discover its manufacturing process, characteristics, comparison and advantages ...

Dental zirconic discontent manufacturing process:

There Fabrication of zirconic discs Dental is a high-precision industrial process including several key stages aimed at obtaining a homogeneous, pre-conceited and loaning block.

The main steps include in particular:

• Preparation of zirconia powder: it all starts with a very high purity (Zro₂) zirconic powder, generally stabilized by adding ~ 3 to 5 % yttrium oxide.
• Biocompatible nanopoudres are used with fine and regular grains, a guarantee of a dense microstructure after sintering.
• The incorporation of additional components makes it possible to obtain the desired shade.

Milaenium zirconic discs are made with isostatic pressure.

The composition of the material to make a disc is compacted in a mold which is put under high pressure.

• The disc is built by a vertical pressure supplemented by a cold pressing called " isostatic For the pressure is regular and perfect on all sides of the disc.
• This manufacturing technique is important for the part carried out conforms to demand after the final sintering.
• THE Multilayer discs (Multilayer) are assembled with the shade during the multilayer construction phase before pressing.
• The prosthetist no longer needs infiltration dyes to obtain the desired shade.
• The pre-fritéed disc cools very slowly so that no internal constraints come to destroy the production of the prosthesis.

Multilayer zirconic discs, available in 98 mm standard format.

The sinterization phase is practiced in a conventional way according to the manufacturer's recommendations, we advise you to respect the user manual provides in each box.

• All discs are visually controlled by the manufacturer before shipping to certify the absence of crack.

Milaenium 4D zirconic disc + Multilayer: Technical characteristics:

The material used for the creation of a 4D+ Milaenium disc+ disc By the manufacturer represents one of the most technologically advanced dental zircones.

• It is a pre-interest zirconic disc, designed to offer an ideal balance between robustness and aesthetics.
• Concretely, the disc is made up of five layers Successive of Zirconia, whose composition and shade vary gradually from the base to the top.
• This results in a continuous gradant of properties: the color goes from darkest in the darkest to the clearest towards the incisal, mechanical resistance decreases from around 1,200 MPa to 700 MPA, and translucidity increases from ~ 43 % to ~ 55 % of the collar to the incisal.
• By definition, the cervical part is more opaque and ultra-resistant to ensure structural support, while the incisal part is more translucent and slightly less hard to imitate natural enamel.

Milaenium 4D +presents the following technical specifications:

Flexion resistance: gradant of approximately 700 MPa (in incisal zone) up to 1,200 MPa (in cervical zone).

This gives him the ability to bear the constraints of complete bridges While being solid enough to avoid bursts by incisal edge.

• By way of comparison, 1,200 MPa exceeds the resistance of many other dental ceramics, testifying to the robustness of the Zircon.
• Translucidity: gradient of 43 % to 55 % (measured 1 mm thick) from the bottom to the top of the disc.
• The ultra-translucent incisal area (~ 55 %) makes it possible to reproduce the natural transparency of the free edges of the teeth, while the more opaque area (~ 43 %) effectively masks the dental hook or the underlying implant pillar.

Zircony Milaenium pre-colored for a transition from realistic shade through its layers.

Possibility to personalize with our range of stains.

• Fritted density: ~ 6.0 g/cc once fried at full temperature.
• This Very high density (Close to theoretical density) indicates the almost total absence of residual porosity in the final material, a guarantee of solidity and stability.
• Biocompatibility : Like all Y-TZP zircones, 4D Plus is a bio-tail material. It does not interact with the oral environment and causes neither allergy or tissue irritation, a major asset for sensitive patients.
• His inert behavior And its chemical stability make it a material perfectly tolerated by the body in the long term.
• Final sintering temperature: 1500 ° C (level of approximately 2 recommended) to obtain complete densification.
• This cooking temperature Relatively standard makes it compatible with most sintering ovens on the market.

Thanks to this combination of properties by the manufacturer, Milaenium 4D + is classified as high-resistance ultra-translucent zircones.

She offers a Optimal compromise between aesthetics and performance : sufficiently translucent for demanding previous restorations, and sufficiently resistant for posterior areas and complete bridges.

• This product can cover all clinical indications, from the unitary crown to complete bridge with a single type of material.
• In conclusion, the More multilayer milaenium 4D is positioned as a universal zircony of high -end class, capable of simplifying the choice of uncompromising prosthetist on the result.

Comparison of the Milaenium 4D+ ML zirconic disc with other types of zirconia on the market:

There are several categories of dental zirconia, each having its specificities in terms of composition, transluid and resistance.

Here's how our positioning is compared to Main types of zirconia Available:

• Monolithic zirconia Classic (1ʳᵉgeneration): These are the first Y-TZP zircones used in dentistry, of uniform composition (often ~ 3 mol% y₂o₃).
• They offer very high resistance (Typically> 1000MPA) But are quite opaque (translucidity <40 %).
• Historically, they were used for robust reinforcements with a ceramic covering for aesthetics.
• As noted above, this stratification could cause recurring shipping effects.

Milaenium has a clearly higher translussity And incorporates the shade into the mass, which makes it possible to use it monolithically including in the previous sector by avoiding the risks of shipping.

High translucent zirconia (2nd generation): to gain aesthetics, zircones enriched with YTTRIUM (4Y or 5Y-TZP) have been developed, often called ultra-translucent zircones.

• These have a very high translucidity (up to ~ 50 % or more) and a homogeneous shade, allowing monolithic crowns of an aesthetic close to that of lithium disilical.
• In return, their mechanical resistance is reduced (generally around 600–800 MPa), which can limit their use to unit restorations or short bridges.
• Milaenium 4D Plus ML Aims to combine the best of these two worlds: it reaches translucent comparable to the most aesthetic zircones (≈55 % in incisive) while keeping, in its low layers, a resistance close to conventional zircones (≈1200 MPa in cervical), which considerably widens the possible indications without sacrificing reliability.
• Traditional multi-layer zirconia: Many manufacturers offer multilayer pre-tank discs (sometimes called 2D or 3D multilayer according to marketing) which incorporate a color gradient through the thickness of the disc.
• These Standard multi -layer zircones Improve the aesthetics compared to a united zirconia, by reproducing for example a more intense collar and a lighter enamel.
• However, in most initial cases, the basic material remained identical throughout the thickness, only the coloring changed by layer.
• Translucent and resistance therefore remained uniform in the disc.

Milaenium goes further: not only does it have a shade gradant, but it also changes the microstructure of the zircony according to the layers (by variation in the concentration of yttrium and aluminum oxide).

• The result is a simultaneous gradient of optical and mechanical properties, imitating the dentin-email transition of a natural tooth.
• In this, 4D Plus belongs to the new generation of highly advanced zircones compared to first generation multilayers.
• Multilayer 3D zirconia (recent generation): The Multilayer 3D term refers to very similar latest generation zircones in the Spirit with 4D Plus.
• For example, a typical multilayer 3D zirconia has an increasing translucidity of around 43 % to 55 % and a decreasing resistance from ~ 1250 MPa to 750 MPa from the collar to the incisive.
• Values ​​almost identical to those announced for Milaenium 4D Plus.

In practice, Milaenium aligns with these advanced performance, with its own formulation and internal layout in 5 layers.

The difference between “3D” and multilayer “4D” is mainly due to the owner process and the optimizations provided by each manufacturer.

• Milaenium highlights a particularly progressive transition Between the layers and a controlled dimensional stability, which ensures harmonious integration of the shade and the resistance throughout the height of the tooth.
• For the clinician as for the dental prosthetist, these new generation 3D/4D zircones all offer a crucial advantage: the possibility of making monolithic restorations that are both aesthetic and solid, covering a wide range of clinical cases with a single type of disc.

In summary, the manufacture of more multilayer milaenium 4D zirconia is at the top of the hierarchy of current zircones.

• It combines the advantages of high resistance zircones and highly aesthetic zircones, thanks to its innovative multilayer design.
• Compared to older materials, it represents a versatile solution without compromise, which makes it a choice of predilection for dental laboratories and clinics in search of reliability and aesthetic excellence.

Specific advantages of Milaenium 4D Plus zirconia for prosthetists and dentists:

The adoption of more multilayer 4D zircony brings many practical and clinical benefits.

Here are the main advantages that this material offers to dental prosthetists and dentists:

• Higher natural aesthetic: Thanks to its Multi -layer gradient of shade and translucidity, the 4D Plus makes it possible to obtain a restoration with a very natural rendering.
• The collar transition from the collar to the incisal imitates that of a real tooth, with a more saturated collar and a more translucent incisive edge.
• The monolithic result is so aesthetic that a simple glaze or some minimal make -up are generally sufficient to perfect the crown.
• Thus avoids the installation of stratification ceramic, while obtaining a harmony of shade over the entire thickness.
• Intrinsic aesthetic quality, combined with an excellent balance/transparency balance, makes it possible to make high-end all-ceramic restorations without compromise.
• High resistance and durability: Zircony is recognized for its exceptional mechanical resistance in the mouth, supporting without failing the repeated masticatory loads in the long term.

The 4D Plus zirconia, with its reinforced base, can be used with confidence from 1 to 14 elements.

His high tenacity gives it excellent resistance to fractures and bursts.

• Unlike more fragile ceramic crowns, a more 4D monolithic crown does not have any low layer likely to crack.
• In addition, studies show that zircony restorations have excellent clinical survival rates over many years.

By choosing 4D Plus, the prosthetist opts for a lasting solution, even in patients with strong constraints (Bruxomans, posterior teeth, etc.).

• Biocompatibility and security: as mentioned, the zircony y-tzp is a material bio-tail which does not cause an adverse reaction. No allergy to zirconium oxides has been postponed, which makes it ideal for patients allergic to metals (an interesting alternative even towards titanium implants).
• Zircony is not heat conductive Nor electricity, and its polished surface is well tolerated by gingival tissues.
• The use of 4D Plus therefore ensures restoration biologically neutral, minimizing the risks of inflammation or awareness.
• Ease of work for the prosthetist: Milaenium 4D Plus was designed for Simplify the workflow in the laboratory.
• Being already tinged and laminated in the factory, it eliminates the time -colored coloring step by liquid infiltration.
• According to estimates, the absence of manual dye can accelerate production by around 20 % and reduce labor costs by almost 30 %.

The material in the pre-fritéed state is easy to machine: its moderate hardness before cooking (≈ 1250 HV on the surface), faster milling, less wear of strawberries, optimal machining precision.

• THE dental prosthetist can thus make fine adjustments and detailed anatomies without difficulty.
• At the end of the machining, the pre-integrated PRPOSES already presents its gradient of final color; After sintering, icing or surface shades can be applied.
• This efficiency and this simplicity implementation are major assets for laboratories, which gain productivity and reliability of result.

Respect for the integrity of antagonistic teeth: a profit sometimes ignored by zircones with gradual hardness.

• Indeed, the Sweeter superficial layer (approximately 1250 HV) of the crown is less abrasive than very hard conventional zircones, which can limit the damage or wear of the enamel of the antagonistic teeth over time
• Of course, it remains essential to polish or freeze the zirconia after sintering to obtain a smooth surface, but the very structure of the material is optimized to preserve the neighboring natural dentition.

In conclusion, the zirconic Milaenium 4D + ML disc illustrates the importance of technological advances in dental materials.

• It represents a major ally to make high -level ceramic restorations.
• By combining innovation (graduated multilayers), technical performance (Optimized solidity and translucidity) and reliability (Constant product quality), it underlines how much the choice of good material is essential to achieve excellence in prosthetic dentistry.

In partnership with a renowned manufacturer, Massilia Dental hopes that each prosthetist, anxious to offer the best to his patients, positively considers this new generation zirconic product to guarantee light, functional and lasting results to its customers.
