A 22 mm titanium disc for demanding implant and prosthetic cases
The Milaenium Grade 5 titanium disc 98 x 22 mm is intended for laboratories that need significant height for milling larger metal structures. It can cover indications where 18 or 20 mm thicknesses may become limiting depending on part orientation, sprues or prosthetic geometry.
This version is particularly relevant for productions requiring a reinforced vertical reserve within the disc: implant bars, abutments, superstructures, technical bridges or high frameworks produced by CAD/CAM milling.
Grade 5 Ti-6Al-4V titanium provides the laboratory with a material recognized for its mechanical strength / light weight ratio, provided it is processed with a titanium-compatible milling unit, suitable burs, a controlled CAM strategy and effective liquid cooling.
Professional indications for the 98 x 22 mm disc
The Milaenium Grade 5 titanium disc 98 x 22 mm is intended for dental prosthetics laboratories producing high or complex parts within a professional titanium milling workflow.
- Implant bars requiring significant useful height.
- Custom abutments according to design and indications.
- Screw-retained bridges or technical implant structures.
- Implant superstructures according to CAD/CAM validation.
- Reinforced frameworks and large-height metal parts.
- Prosthetic cases where a 22 mm thickness secures CAM positioning.
A vertical reserve for high restorations
The 22 mm thickness gives the dental technician additional margin to organize part placement, manage sprues, orient structures and preserve milling safety in the CAM software.
It is positioned above 18 and 20 mm thicknesses for cases where useful height becomes a major criterion. It remains more rational than a 25 mm thickness when the case does not require the maximum available height.
The choice of disc must always be confirmed by the CAD file, the actual height of the restoration, the constraints of the implant system, the kinematics of the milling unit, bur diameter and the selected milling strategy.
Grade 5 Ti-6Al-4V titanium: strength, stability and dental milling
Grade 5 titanium, also designated Ti-6Al-4V or TC4, is a titanium alloy combining titanium, aluminium and vanadium. It is selected when the laboratory is looking for a material stronger than commercially pure titanium for technically loaded dental restorations.
- High mechanical strength for demanding prosthetic structures.
- Interesting strength-to-weight ratio for milled implant parts.
- Useful rigidity for bars, abutments, bridges and superstructures.
- Compatibility with dental CAD/CAM workflows under a suitable protocol.
- Finishing possible according to the laboratory’s professional methods.
To obtain consistent results, the laboratory must combine the material with a coherent production environment: validated CAD design, milling under coolant fluid, titanium burs in good condition, precise clamping and an adapted finishing protocol.
Understanding titanium grades used in dentistry
Titanium discs intended for dental prosthetics may belong to different material families. Pure grades often prioritize ductility, while alloys such as Grade 5 are selected for work requiring greater mechanical strength.
| Grade | Family | Laboratory interpretation |
|---|---|---|
| Grade 1 | Commercially pure titanium | Very ductile, softer, suitable for indications where loads remain moderate. |
| Grade 2 | Commercially pure titanium | Good overall behavior for certain restorations or parts with lower mechanical loading. |
| Grade 4 | Reinforced pure titanium | Stronger than lower pure grades, used in certain prosthetic and implant applications. |
| Grade 5 | Ti-6Al-4V alloy | High-strength alloy, relevant for implant structures and more highly loaded dental restorations. |
| Grade 5 ELI / Grade 23 | Ti-6Al-4V with enhanced purity | Version with reduced interstitial element content, used for demanding medical, implant and prosthetic applications. |
Why is Grade 5 coherent for a 22 mm thickness?
A 22 mm thickness is generally selected for higher, larger or more technical parts. In this type of indication, choosing a material such as Grade 5 titanium helps meet requirements for strength, rigidity and dimensional stability.
Ti-6Al-4V is particularly relevant for milled implant restorations, bars, custom abutments and superstructures when the design requires a material capable of withstanding higher mechanical loads.
The laboratory must nevertheless maintain a rigorous approach: the material does not compensate for insufficient design. Cross-sections, connectors, sprue areas, orientations and CAM parameters must be validated before production.
A choice suited to CAD/CAM implant structures
Grade 5 is a technical choice for laboratories producing milled titanium restorations requiring a higher strength level than the most common pure titanium grades.
- Suitable for large-height structures according to design.
- Relevant for implant bars and superstructures.
- Good balance between mechanical strength, rigidity and light weight.
- Compatible with dental milling units designed for titanium.
- Milling to be carried out under suitable liquid cooling.
The choice of Grade 5 titanium must always be combined with the laboratory manufacturing protocol, the case indications and the recommendations of the CAD/CAM environment used.
22 mm thickness: reinforced height for complex structures
The Milaenium Grade 5 titanium disc 98 x 22 mm is suitable for cases where the laboratory needs a significant material reserve without systematically moving to the highest format in the range. It offers useful height adapted to implant restorations, abutments and large structures according to CAD/CAM validation.
| Thickness | Recommended use orientation |
|---|---|
| 10 to 12 mm | Compact restorations, single units, crowns and small frameworks. |
| 14 to 16 mm | Intermediate work, compact bridges, frameworks and moderate-height restorations. |
| 18 to 20 mm | Technical bridges, reinforced frameworks, abutments and implant structures with significant height. |
| 22 mm | Implant bars, high abutments, screw-retained bridges and superstructures requiring reinforced vertical reserve. |
| 25 mm | Very large cases, complex restorations and structures requiring the maximum height of the range. |
Selection of the 22 mm disc must be confirmed in the CAD/CAM software according to the actual height of the restoration, milling orientation, sprues and milling unit limitations.
Milling recommendations for the 98 x 22 mm titanium disc
The Grade 5 titanium disc 98 x 22 mm must be milled on a machine compatible with titanium alloys, with a suitable Ø 98 mm holding system, specific burs and a CAM strategy designed for Ti-6Al-4V.
- Check milling unit compatibility with Grade 5 titanium.
- Check the useful 22 mm height in the CAD/CAM software.
- Use titanium burs suitable for high parts.
- Position sprues to secure larger structures.
- Check disc tightening before starting milling.
- Maintain effective liquid cooling throughout the entire cycle.
Finishing titanium implant structures
Parts milled from a 22 mm disc require careful finishing, especially around sprue areas, functional surfaces, emergence profiles and prosthetic interfaces according to the type of restoration produced.
- Use efficient suction extraction during adjustments.
- Limit heat build-up when separating parts.
- Use instruments compatible with titanium.
- Clean structures thoroughly before final inspection.
- Follow the personal protective equipment rules defined for titanium work.
Recommended milling protocol for Grade 5 titanium
Milling Grade 5 titanium requires precise control of heat, cutting force and chip evacuation. On a 22 mm thickness, machine stability, clamping quality and tool condition directly influence result consistency.
For reliable production, the laboratory must combine a titanium-compatible milling unit, burs suitable for Ti-6Al-4V, a CAM strategy validated for high parts and continuous liquid cooling during milling.
Checks before production
- Confirm that the milling unit accepts Grade 5 titanium.
- Check the Ø 98 mm disc holding system.
- Check the condition of the dedicated titanium burs.
- Choose a CAM strategy suitable for high structures.
- Validate part positioning within the 22 mm height.
- Check coolant fluid before starting the cycle.
Milling under liquid cooling
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 helps limit heat build-up, preserve burs, facilitate chip evacuation and secure production of implant bars, abutments, screw-retained bridges and Grade 5 titanium superstructures.
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 22 mm
When should a Grade 5 titanium disc 98 x 22 mm be selected?
The 98 x 22 mm disc is suitable for cases requiring significant useful height within the disc: implant bars, custom abutments, screw-retained bridges, superstructures or high frameworks according to the CAD/CAM design.
This thickness is relevant when the laboratory needs to secure sprue positioning, orient a complex structure or maintain a more comfortable vertical margin than with a 20 mm disc. Validation must always be carried out in the design and milling software.
What is the difference between a 20 mm and a 22 mm titanium disc?
The 22 mm version provides additional vertical reserve compared with the 20 mm disc. It can be useful when the restoration has greater height, when orientation within the disc is more restrictive or when sprues require more space.
The choice must remain technical. If the case is fully secured within a 20 mm thickness, increasing the height is not necessary. However, the 22 mm version becomes relevant for implant or prosthetic restorations requiring greater margin.
Is Grade 5 titanium suitable for implant superstructures?
Grade 5 titanium, also called Ti-6Al-4V or TC4, is sought after for its mechanical strength, rigidity and strength-to-weight ratio. It can be used for implant superstructures, bars, abutments or technical bridges when the design and manufacturing protocol allow it.
Validation depends on the system used, prosthetic indications, geometry, connections, CAM parameters and laboratory controls. Material traceability and compliance of the production workflow must always be retained.
Should the 22 mm titanium disc be milled under liquid cooling?
Yes, titanium milling must be carried out with a suitable coolant fluid, unless a contrary protocol has been explicitly validated by the milling unit, tool and CAM software manufacturers.
For a 22 mm thickness, cooling is particularly important because cycles may be longer and parts larger. It helps limit heat build-up, preserve burs, evacuate chips and secure surface quality.
What checks should be carried out before milling a 22 mm thickness?
Before milling, the laboratory must check machine compatibility with Grade 5 titanium, bur condition, disc tightening, CAM strategy, available height and part orientation within the disc.
It is also important to check sprue positioning, absence of interference in toolpaths, clamping stability and coolant fluid quality. These checks limit the risks of heat build-up, tool breakage or rework after milling.
