An 18 mm titanium disc for more technical dental restorations
The Milaenium Grade 5 titanium disc 98 x 18 mm meets the needs of laboratories looking for a more comfortable disc height for milled metal restorations. It makes it possible to approach larger cases than compact thicknesses, while retaining a Ø 98 mm format suited to compatible open workflows.
This thickness is relevant when the laboratory needs to secure CAM positioning, manage higher parts, place sprues with greater margin or produce structures requiring a greater vertical reserve.
Grade 5 Ti-6Al-4V titanium offers an interesting combination for dental CAD/CAM: mechanical strength, light weight, stability and compatibility with titanium milling protocols when the machine, burs and coolant fluid are suitable.
Professional applications of the 98 x 18 mm disc
The Milaenium Grade 5 titanium disc 98 x 18 mm is designed for dental prosthetics laboratories wishing to produce higher metal structures in a controlled CAD/CAM environment.
- Crowns and single-unit restorations requiring more height.
- Compact or intermediate bridges according to design.
- Reinforced metal frameworks intended for veneering.
- Custom abutments according to indications and laboratory protocol.
- Moderate-height implant bars according to CAD/CAM validation.
- Technical prosthetic structures requiring a greater material reserve.
A useful height for more demanding cases
The 18 mm thickness gives the dental technician a greater vertical margin than 14 or 16 mm discs. It becomes relevant when the restoration requires more height, a specific orientation or more comfortable sprue positioning.
This variant remains suitable for rational production: it provides more reserve without automatically switching to the highest thicknesses in the range, which are reserved for larger or more complex cases.
The final choice must always be confirmed in the CAD/CAM software according to the prosthetic height, part orientation, bur diameter, milling strategy and milling unit limitations.
Grade 5 Ti-6Al-4V titanium: a material suited to loaded structures
Grade 5 titanium, also known as Ti-6Al-4V or TC4, is a titanium alloy combining titanium, aluminium and vanadium. It is used in dental laboratories when the restoration requires greater mechanical strength than commercially pure titanium.
- High mechanical strength for technical dental structures.
- Good strength-to-weight ratio for milled restorations.
- Interesting rigidity for bridges, frameworks and implant components.
- Material compatible with adapted dental CAD/CAM protocols.
- Finishing possible according to the laboratory’s professional procedures.
Successful milling depends on respecting the complete protocol: titanium-compatible machine, burs suitable for Grade 5, stable clamping, coherent CAM strategy and effective liquid cooling during milling.
Differences between titanium grades for dental prosthetics
Titanium used in dentistry exists in several grades. Commercially pure titanium grades are valued for their ductility and corrosion resistance, while alloys such as Grade 5 are selected when mechanical loads become more significant.
| Grade | Family | Laboratory positioning |
|---|---|---|
| Grade 1 | Commercially pure titanium | Very ductile, softer, oriented toward less demanding applications. |
| Grade 2 | Commercially pure titanium | Good overall behavior for certain restorations where the required strength remains moderate. |
| Grade 4 | Reinforced pure titanium | Higher strength than lower pure grades, used in certain prosthetic or implant indications. |
| Grade 5 | Ti-6Al-4V alloy | High-strength alloy, relevant for more highly loaded dental structures. |
| 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 relevant for an 18 mm thickness?
With a 18 mm thickness, the laboratory enters a more technical application range than compact formats. Restorations can be higher, more heavily loaded or require more complex geometry. In this context, Grade 5 titanium provides useful mechanical strength.
Its Ti-6Al-4V alloy is particularly relevant for bridges, reinforced frameworks, custom abutments and implant components when the prosthetic design requires a stable, lightweight and mechanically high-performance material.
Grade 5 must nevertheless be used within a controlled protocol: adapted design, coherent cross-sections, milling under cooling, compatible tools and finishing carried out with instruments suited to titanium.
A technical choice for titanium CAD/CAM workflows
In dental CAD/CAM milling, Grade 5 is selected when the laboratory wants to produce structures that are more robust than those generally assigned to softer pure titanium grades.
- Suitable for intermediate-height or higher restorations.
- Relevant for bridges, frameworks and implant components.
- Good compromise between mechanical strength and low density.
- Compatible with milling units designed for titanium.
- Milling recommended under irrigation / liquid cooling.
The choice of Grade 5 titanium must always remain consistent with the prosthetic case, manufacturing indications and the protocol validated by the laboratory.
18 mm thickness: more height for technical work
The Milaenium Grade 5 titanium disc 98 x 18 mm is positioned as a thickness suited to work requiring more useful height than a 16 mm disc. It offers an appreciable material reserve for more demanding prosthetic cases, without reaching the volume of 20, 22 or 25 mm discs.
| 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 mm | Bridges, reinforced frameworks, abutments, implant components and structures requiring more useful height. |
| 20 mm | Higher work: implant bars, superstructures and cases requiring significant vertical reserve. |
| 22 to 25 mm | Large structures, complex cases and restorations requiring maximum material height. |
Validation of the 18 mm thickness must be carried out in the CAD/CAM software according to the actual height of the restoration, sprue positioning, milling orientation and equipment limitations.
Milling recommendations for the 98 x 18 mm titanium disc
The Grade 5 titanium disc 98 x 18 mm must be milled on a machine compatible with titanium, with a suitable Ø 98 mm holder, dedicated burs and a CAM strategy specific to the Ti-6Al-4V alloy.
- Check milling unit compatibility with Grade 5 titanium.
- Use suitable and properly maintained titanium burs.
- Validate the 18 mm height according to the restoration to be produced.
- Place sprues securely in the CAM software.
- Check tightening of the Ø 98 mm disc before milling.
- Maintain effective liquid cooling during milling.
Finishing Grade 5 titanium parts
After milling, titanium restorations must be separated, adjusted and finished with compatible instruments. Finishing must preserve the surface condition, limit heat build-up and comply with the laboratory’s professional protocols.
- Work with suction extraction suitable for titanium dust.
- Limit pressure during deburring and adjustments.
- Use instruments reserved for or compatible with titanium.
- Clean parts thoroughly before the next steps.
- Follow the laboratory’s personal protective equipment rules.
Recommended milling protocol for Grade 5 titanium
Milling Grade 5 titanium requires precise management of temperature, chip evacuation and tool wear. The material is resistant, but it requires a rigorous protocol to obtain consistent surfaces and preserve bur service life.
For the 98 x 18 mm disc, the laboratory must combine a titanium-compatible milling unit, tools suitable for Ti-6Al-4V, stable clamping, a validated CAM strategy and continuous liquid cooling during milling.
Checks before production
- Confirm that the machine accepts Grade 5 titanium.
- Check the Ø 98 mm disc holding system.
- Check the condition of the dedicated titanium burs.
- Select a CAM strategy adapted to the Ti-6Al-4V alloy.
- Validate part positioning within the 18 mm height.
- Check the level and quality of the coolant fluid.
Milling under liquid cooling
Titanium and its 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 control heat build-up, extend bur service life, improve chip evacuation and secure the milling of bridges, frameworks, abutments and moderate-height implant 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 18 mm
When should a Grade 5 titanium disc 98 x 18 mm be selected?
The 98 x 18 mm disc is suitable for restorations requiring more useful height than the 14 or 16 mm versions. It may be relevant for bridges, reinforced frameworks, custom abutments, implant components or technical structures according to the CAD/CAM design.
The laboratory must check the actual height of the part, orientation within the disc, sprue positioning and milling unit limitations before production. For very large superstructures, a greater thickness may be more appropriate.
What is the difference between a 16 mm and an 18 mm titanium disc?
The 18 mm version provides greater vertical reserve than the 16 mm disc. It becomes relevant when the restoration requires more height, when sprues need to be placed more securely or when the case geometry limits possible orientation in the CAM software.
The choice must remain based on the real case: if the restoration fits comfortably within 16 mm, using more material is not always necessary. However, the 18 mm version provides a useful margin for more technical work.
Is Grade 5 titanium suitable for implant components?
Grade 5 titanium, also known as Ti-6Al-4V or TC4, is sought after for its high mechanical strength and good strength-to-weight ratio. It may be relevant for certain implant components, custom abutments, moderate-height bars or technical prosthetic structures according to indications.
Validation depends on the design, connection type, case requirements, laboratory protocol and the recommendations applicable to the system used. The material must always be milled and finished within a controlled professional workflow.
Should the 18 mm titanium disc be milled with coolant fluid?
Yes, titanium milling must be carried out with suitable liquid cooling, unless a contrary protocol has been explicitly validated by the milling unit, tool and CAM software manufacturers.
Cooling helps limit heat build-up, preserve burs, improve chip evacuation and secure the surface condition. For Grade 5 titanium, this precaution is essential in regular laboratory production.
What checks should be performed before milling an 18 mm thickness?
Before milling, the laboratory must check milling unit compatibility with titanium, tightening of the Ø 98 mm disc, bur condition, CAM strategy, available height and part orientation.
The coolant fluid, cleanliness of the milling area and consistency of sprue positioning must also be checked. These checks help limit the risks of heat build-up, vibration, premature tool wear or rework after milling.
