A 16 mm titanium disc for intermediate-height dental restorations
The Milaenium Grade 5 titanium disc 98 x 16 mm allows the laboratory to integrate a reliable metal solution into its digital manufacturing workflow. It is intended for productions requiring more height than a compact disc, without reaching the material reserves of thicknesses intended for very large structures.
This 16 mm variant is particularly relevant for restorations where the laboratory wants to secure CAM positioning, maintain a comfortable milling margin and work with a material recognized for its mechanical strength / light weight ratio.
Grade 5 TC4 titanium, also known as Ti-6Al-4V, is suitable for dental CAD/CAM workflows when the milling unit, burs, clamping and coolant fluid are compatible with titanium milling.
Professional indications for the 98 x 16 mm disc
The Milaenium Grade 5 titanium disc 98 x 16 mm is suitable for laboratories looking for a versatile thickness to produce moderate-height metal dental parts.
- Single-unit crowns milled in titanium.
- Compact or intermediate bridges according to design.
- Metal frameworks intended for veneering.
- Prosthetic elements requiring more height than a 14 mm disc.
- Technical laboratory structures with high mechanical demands.
- CAD/CAM cases requiring a better vertical margin within the disc.
A thickness suited to more secure cases
The 16 mm thickness gives the dental technician additional margin to position restorations, manage sprues and secure the orientation of parts in the CAM software.
It differs from the 10, 12 and 14 mm versions by offering a more comfortable useful height, while remaining more rational than an 18 or 20 mm disc when the case does not require a large material volume.
The choice of this thickness must always be confirmed by the CAD design, the actual height of the restoration, milling unit limitations, bur diameter and selected milling strategy.
Grade 5 Ti-6Al-4V titanium: a high-performance alloy for dental CAD/CAM
Grade 5 titanium is a titanium alloy mainly containing titanium, aluminium and vanadium. This composition gives it higher mechanical strength than many commercially pure titanium grades, making it a relevant material for milled technical restorations.
- High mechanical strength for loaded structures.
- Good rigidity for frameworks and intermediate-height bridges.
- Low density compared with many dental metal alloys.
- Compatibility with dental CAD/CAM workflows under a suitable protocol.
- Finishing possible according to the laboratory’s usual procedures.
To use this material correctly, the laboratory must use a titanium-compatible machine, tools suitable for Ti-6Al-4V, effective liquid cooling and CAM parameters consistent with the hardness of the material.
Differences between titanium grades used in dental prosthetics
Not all titanium grades meet the same mechanical requirements. Commercially pure grades prioritize ductility and corrosion resistance, while alloys such as Grade 5 are selected when the restoration requires greater strength and stability.
| Grade | Family | Laboratory interest |
|---|---|---|
| Grade 1 | Commercially pure titanium | Very ductile, softer, suitable for moderate mechanical requirements. |
| Grade 2 | Commercially pure titanium | Good overall behavior, used for certain restorations with lower mechanical loading. |
| Grade 4 | Reinforced pure titanium | Higher strength than the lower pure grades, relevant for certain prosthetic and implant applications. |
| Grade 5 | Ti-6Al-4V alloy | High-strength alloy, relevant for more mechanically loaded dental restorations. |
| Grade 5 ELI / Grade 23 | Ti-6Al-4V with enhanced purity | Version with reduced interstitial element content, used in demanding medical and prosthetic applications. |
Why is Grade 5 suited to 16 mm work?
The 16 mm thickness makes it possible to produce restorations that are higher than very compact cases. In this context, Grade 5 titanium provides useful strength for intermediate bridges, technical frameworks and structures requiring good mechanical support.
Its rigidity and strength-to-weight ratio allow the laboratory to produce robust metal parts while limiting the final mass of the restoration, which remains an important advantage in milled prosthetic work.
Grade 5 does not remove the need for rigorous design: connectors, minimum cross-sections, milling orientation and finishing must be validated according to the prosthetic case and the laboratory protocol.
A technical material for digital workflows
In a CAD/CAM environment, Grade 5 makes it possible to produce demanding metal structures with good manufacturing stability, provided that the specific constraints of titanium milling are respected.
- Relevant for crowns, bridges and intermediate-height frameworks.
- Suitable for parts requiring strength and light weight.
- Compatible with dental milling units designed for titanium.
- Recommended when pure titanium grades are mechanically less suitable.
- To be milled under liquid cooling according to a validated protocol.
For each case, the choice of Grade 5 must be combined with an adapted design, compatible tools and a titanium-specific CAM strategy.
16 mm thickness: a comfortable and versatile material reserve
The Milaenium Grade 5 titanium disc 98 x 16 mm is a very useful transition thickness within a range of dental titanium discs. It offers more freedom than a 14 mm disc for intermediate cases, while remaining more targeted than an 18 or 20 mm disc intended for higher structures.
| Thickness | Recommended use orientation |
|---|---|
| 10 to 12 mm | Compact restorations, crowns, single units and small frameworks. |
| 14 mm | Compact intermediate work requiring more margin than low thicknesses. |
| 16 mm | Crowns, compact bridges, frameworks, technical parts and moderate-height restorations. |
| 18 to 20 mm | Work requiring greater useful height: abutments, bars, bridges and more complex superstructures. |
| 22 to 25 mm | Large structures or cases requiring significant vertical reserve. |
The 16 mm thickness must be validated in the CAD/CAM software according to the actual height of the part, sprues, positioning and mechanical limitations of the milling unit.
Milling recommendations for the 98 x 16 mm titanium disc
The Grade 5 titanium disc 98 x 16 mm must be processed on a dental milling unit compatible with titanium, with a properly adjusted Ø 98 mm holder and a CAM strategy adapted to the Ti-6Al-4V alloy.
- Check that the machine accepts Grade 5 titanium milling.
- Use dedicated titanium burs in good condition.
- Configure CAM parameters according to the material and thickness.
- Check disc tightening before the milling cycle.
- Validate that the 16 mm height is suitable for the case to be produced.
- Monitor chip evacuation and cooling quality.
Professional finishing of titanium restorations
Once the part has been milled, trimming, separation, adjustment and finishing steps must be carried out with instruments compatible with titanium in order to preserve surface quality and limit localized heat build-up.
- Use efficient suction extraction during adjustments.
- Avoid excessive pressure during deburring.
- Use clean instruments suitable for titanium.
- Clean restorations before any finishing or veneering step.
- Follow the personal protective equipment rules defined in the laboratory.
Recommended milling protocol for Grade 5 titanium
Milling Grade 5 titanium requires rigorous management of heat, chips and tool wear. The material is demanding on burs and requires a stable protocol in order to produce consistent restorations in a dental prosthetics laboratory.
For the 98 x 16 mm disc, the laboratory must combine a titanium-compatible milling unit, precise clamping, tools suitable for Ti-6Al-4V, a validated milling strategy and effective liquid cooling during milling.
Essential checks before production
- Confirm milling unit compatibility with titanium.
- Check the Ø 98 mm disc holding system.
- Check the condition of the dedicated titanium burs.
- Select a CAM strategy suitable for Grade 5.
- Validate part positioning within the 16 mm height.
- Check coolant fluid before starting.
Liquid cooling recommended
Titanium and titanium alloys must be milled with a suitable coolant fluid. Dry milling should be avoided unless a protocol has been explicitly validated by the milling unit, tool and CAM software manufacturers.
Cooling limits heat build-up, reduces premature bur wear, facilitates chip evacuation and helps secure the milling of crowns, bridges, frameworks and intermediate-height structures.
Laboratory recommendation: mill the Grade 5 titanium disc under irrigation / coolant fluid suitable for titanium, while following the parameters validated for the machine, tools and CAM software used.

FAQ – Milaenium Grade 5 titanium disc 98 x 16 mm
When should a Grade 5 titanium disc 98 x 16 mm be selected?
The 98 x 16 mm disc is relevant when the laboratory needs to mill restorations that are higher than compact cases while remaining within an intermediate thickness. It is suitable for crowns, compact bridges, frameworks and technical parts according to the CAD design.
This thickness provides a comfortable vertical margin to position parts and sprues in the CAM software. It must be validated according to the actual height of the restoration, milling orientation, tools used and milling unit limitations.
What is the difference between 14 mm and 16 mm in titanium milling?
The 16 mm version provides more material reserve than a 14 mm disc. It can be useful when the restoration has greater height, when sprues require more security or when positioning within the disc requires additional margin.
The choice between 14 and 16 mm must remain guided by the case to be produced. A 16 mm disc should not be selected simply by habit, but when the CAD/CAM design justifies this additional height.
Is Grade 5 titanium suitable for bridges and intermediate frameworks?
Yes, Grade 5 titanium, also designated Ti-6Al-4V or TC4, offers interesting mechanical strength for restorations subjected to higher loads than simple compact elements.
For bridges, frameworks and intermediate structures, it can be a relevant choice when the geometry is properly designed, cross-sections are suitable and milling is performed with tools and parameters compatible with titanium.
Should the 16 mm titanium disc be milled with cooling?
Yes, titanium milling should be carried out with a suitable coolant fluid, unless a contrary protocol has been clearly validated by the milling unit, tool and CAM software manufacturers.
Cooling helps control cutting temperature, limit bur wear, evacuate chips and secure the surface condition of the restoration. For Grade 5 titanium, this precaution is essential in a professional production workflow.
What checks should be carried out before milling a 98 x 16 mm disc?
Before milling, the laboratory must check milling unit compatibility with titanium, bur condition, disc tightening, CAM strategy, available height and sprue positioning.
It is also important to check the coolant fluid level and the cleanliness of the milling area. These checks help limit the risks of overheating, vibration, tool breakage or rework after milling.
