A versatile titanium disc for digital dental production
The Milaenium Grade 5 titanium disc 98 x 14 mm allows dental prosthetics laboratories to produce milled metal structures in a material recognized for its mechanical strength, light weight and stability in a prosthetic environment.
This thickness represents an excellent compromise when the 12 mm version becomes limited for certain cases, without requiring the material volume of a higher disc. It integrates naturally into dental CAD/CAM workflows intended for technical restorations of moderate height.
The laboratory can use it for crowns, compact bridges, frameworks, intermediate elements and prosthetic structures requiring greater positioning freedom than a low-height disc, subject to validation in the CAD/CAM software.
Possible applications with 14 mm thickness
The Milaenium Grade 5 titanium disc 98 x 14 mm is designed for CAD/CAM work carried out by dental professionals looking for a compact disc that is more versatile than a low-thickness option.
- Milled titanium crowns.
- Compact or moderate-height bridges.
- Metal frameworks intended for veneering.
- Intermediate prosthetic elements according to design.
- Technical structures requiring rigidity and light weight.
- Cases where a 14 mm height better secures CAM positioning.
A balanced choice within the titanium range
The 14 mm thickness is positioned between compact discs and higher discs intended for large superstructures. It provides additional design margin for laboratories wishing to produce slightly higher parts without unnecessarily increasing the material volume.
Grade 5 TC4 titanium provides interesting strength for technical restorations while maintaining low density compared with many dental metal alloys.
Final validation always depends on the height of the part, connector geometry, positioning within the disc, available burs and the CAM strategy applied.
A Grade 5 titanium alloy suited to technical restorations
Grade 5 titanium, also known as Ti-6Al-4V or TC4, is a titanium alloy containing aluminium and vanadium. This composition gives it higher mechanical strength than the most common commercially pure titanium grades.
- Particularly interesting strength-to-weight ratio.
- Good rigidity for compact frameworks and bridges.
- Relevant material for dental CAD/CAM workflows.
- Useful stability for technical prosthetic restorations.
- Finishing possible according to the laboratory’s protocols.
To obtain a reliable result, the laboratory must combine the material with a titanium-compatible milling unit, suitable burs, precise disc clamping and effective irrigation during milling.
Understanding the main titanium grades used in dentistry
In dental prosthetics, titanium can be offered in several grades. Each grade has its own balance between purity, ductility, mechanical strength and field of application. The choice therefore does not depend only on the material name, but on the type of restoration to be produced.
| Titanium grade | Material nature | Professional interpretation |
|---|---|---|
| Grade 1 | Commercially pure titanium | Very ductile and softer, mainly reserved for moderate mechanical requirements. |
| Grade 2 | Commercially pure titanium | Good balance between purity, corrosion resistance and less demanding prosthetic uses. |
| Grade 4 | Reinforced commercially pure titanium | Stronger than the lower pure grades, relevant for certain implant and prosthetic indications. |
| Grade 5 | Ti-6Al-4V alloy | High-strength alloy, suited to dental structures subjected to greater mechanical loads. |
| Grade 5 ELI / Grade 23 | Ti-6Al-4V with enhanced purity | Version with reduced interstitial element content, used in demanding medical, implant and prosthetic applications. |
Why is Grade 5 relevant for a 14 mm thickness?
In an intermediate thickness such as 14 mm, Grade 5 makes it possible to produce compact or moderately high structures while maintaining a high level of strength. This is an advantage when the restoration includes thin sections, technical connectors or a geometry that is more demanding than a simple single unit.
Ti-6Al-4V provides useful rigidity for compact bridges, frameworks and restorations requiring good mechanical behavior without excessively increasing the weight of the structure.
The laboratory therefore benefits from a coherent material for technical parts, provided that CAM parameters and titanium milling instructions are followed.
A coherent material for CAD/CAM milling
Grade 5 is often preferred when the laboratory wishes to mill metal restorations that are more resistant than those made from softer pure titanium grades.
- High mechanical strength for loaded structures.
- Relevant for crowns, compact bridges and frameworks.
- Good balance between light weight and rigidity.
- Adapted to professional dental CAD/CAM workflows.
- Milling to be carried out with suitable liquid cooling.
Grade 5 must be selected according to the indication, prosthetic design and laboratory manufacturing protocol.
14 mm thickness: a versatile height for intermediate work
The Milaenium Grade 5 titanium disc 98 x 14 mm is suitable for laboratories seeking a more comfortable useful height than 10 or 12 mm thicknesses, while remaining in a compact format. This thickness is particularly relevant for restorations where the available height must be secured without switching to larger discs.
| Thickness | Recommended use orientation |
|---|---|
| 10 to 12 mm | Compact work, crowns, single units and small low-height frameworks. |
| 14 mm | Crowns, compact bridges, intermediate frameworks and moderately high structures according to design. |
| 16 mm | Versatile use with greater material reserve for higher or more secure restorations. |
| 18 to 20 mm | Work requiring greater useful height: bars, abutments, bridges and more technical superstructures. |
| 22 to 25 mm | Large structures or complex cases requiring a significant material reserve. |
The choice of thickness must always be confirmed in the CAD/CAM software according to the actual height of the part, sprues, milling orientation and milling unit limitations.
Milling recommendations for the 98 x 14 mm disc
The Grade 5 titanium disc 98 x 14 mm must be used exclusively on a milling unit compatible with titanium and with a holding system adapted to Ø 98 mm discs.
- Check material compatibility in the CAM software.
- Select burs designed for titanium milling.
- Adapt parameters to the Ti-6Al-4V alloy.
- Check clamping before starting the cycle.
- Ensure that the available 14 mm height covers the prosthetic requirement.
- Replace worn tools to limit heat build-up and vibration.
Finishing titanium structures
After milling, the parts must be separated, deburred and prepared according to the laboratory’s internal protocol and the recommendations applicable to dental titanium.
- Use efficient suction extraction during adjustments.
- Avoid overheating during finishing.
- Use instruments suitable for titanium.
- Clean restorations thoroughly before the next steps.
- Follow the personal protective equipment rules defined in the laboratory.
Recommended milling protocol for Grade 5 titanium
Milling Grade 5 titanium requires particular attention to cutting temperature, chip evacuation and bur condition. The material places high demands on tools and can heat up quickly if the CAM strategy or cooling is not suitable.
For reliable production, the disc must be milled on a titanium-compatible machine, with dedicated tools, stable clamping, a coherent milling strategy and an effective coolant fluid during milling.
Checks before starting
- Confirm that the milling unit accepts Grade 5 titanium.
- Check the Ø 98 mm disc holder.
- Use burs suitable for Ti-6Al-4V.
- Choose a titanium-specific CAM strategy.
- Check the positioning of the parts within the 14 mm height.
- Check the level and quality of the coolant fluid.
Milling with liquid cooling
Titanium and titanium alloys must be milled with suitable liquid cooling. Dry milling should be avoided unless a protocol has been clearly validated by the milling unit, tool and CAM software manufacturers.
Cooling helps limit heat build-up, preserve burs, improve chip evacuation and secure the production of crowns, compact bridges, intermediate frameworks and technical structures.
Laboratory recommendation: mill the Grade 5 titanium disc under irrigation / coolant fluid suitable for titanium, while following the parameters validated for the milling unit, tools and CAM software used.

FAQ – Milaenium Grade 5 titanium disc 98 x 14 mm
What type of work is the Grade 5 titanium disc 98 x 14 mm suited to?
The 98 x 14 mm disc is suitable for restorations requiring greater height than very compact versions, while remaining in an intermediate format. It can be used for crowns, compact bridges, frameworks and moderate-height structures according to the CAD design.
Before each milling operation, the laboratory must check that the available thickness covers the actual height of the part, sprues, orientation within the disc and milling unit limitations. For larger structures, a greater thickness may be more suitable.
Why choose 14 mm rather than 12 mm?
The 14 mm thickness provides additional material reserve compared with a 12 mm disc. It may be useful when the restoration is slightly higher, when CAM positioning requires more margin or when the laboratory wants to secure certain compact bridges and intermediate frameworks.
The choice must remain technical: it depends on the restoration geometry, occluso-cervical height, type of sprues, milling strategy and available space within the disc.
Is Grade 5 titanium relevant for frameworks and compact bridges?
Yes, Grade 5 titanium, also known as Ti-6Al-4V or TC4, offers higher mechanical strength than the most common commercially pure titanium grades. It is therefore relevant for technical restorations requiring a good balance between rigidity, light weight and stability.
For frameworks and compact bridges, this material may be appropriate when the prosthetic design includes suitable sections and the laboratory follows titanium milling parameters.
Should the 14 mm titanium disc be milled with water?
Titanium must be milled with a suitable coolant fluid. In practice, it is more accurate to refer to milling under irrigation or liquid cooling, as the exact protocol depends on the milling unit, coolant used, burs and CAM parameters.
Dry milling should be avoided unless explicitly validated by the milling unit, tool and software manufacturers. Cooling reduces heat build-up, preserves burs and helps secure the surface quality of the milled part.
How should the 14 mm thickness be validated before production?
Validation is carried out in the CAD/CAM software by checking the total height of the restoration, part orientation, sprue positioning, safety distance and planned milling strategy.
The laboratory must also check that the disc is correctly clamped, that the burs are suitable for titanium and that liquid cooling is operational. These checks limit the risk of rework, overheating or poor finishing.
