What the solution adds
Cobalt-chromium base + burnout coping = a more controlled route to cast or digitally designed screw-retained restorations
IPD cobalt-chromium bases combine aprecise metal interface a burnout copingfor laboratory waxing, casting or a hybrid CAD/CAM workflow. The supplied CREAS EN product presentation highlights three core benefits:versatility, reliable integration in both conventional and digital workflows a time efficiency. In practice, this means less improvisation in the critical implant-interface zone and a more predictable transfer from design to the definitive restoration.
Suitable for conventional and hybrid CAD/CAM workflowsThe bases can be used for conventional wax-up and casting, or in workflows where positions are first captured with a scan body and the corresponding CAD library.
An interface that gives the restoration a stable foundationThe implant interface is a critical zone in implant prosthodontics. The workflow therefore emphasises accurate seating, anti-rotation and screw-channel control before the restoration is delivered.
Ready for TPA / ASC workflowsFor angulated indications, the Co-Cr base works with TPA fixation screws featuring a pentalobular drive, allowing screw access at angles up to 25°.
SEO & UX note:Users need to understand that this product group is more than a “casting base”. It bridges conventional laboratory work, digital libraries, scan-body workflows and later servicing through TPA screws and RA instruments.

Key strengths
Three benefits highlighted in the original IPD product communication
The “Co-Cr Base” product card centres on three themes: versatility, reliable integration and time efficiency. Here they are translated into practical value for both laboratory and clinic.
Versatility
Compatibility with different workflows and prosthetic solutions gives the laboratory greater flexibility in both workflow and manufacturing strategy.
Reliable integration
IPD highlights optimised accuracy in both digital and physical environments. This matters whenever CAD design alternates with physical verification on the working model.
Time efficiency
An efficient component design simplifies clinical and laboratory steps, reduces improvisation and helps keep the workflow predictable.
Position capture and CAD/CAM integration
Scan bodies and CAD libraries bring Co-Cr bases into the digital workflow
When the laboratory or clinic needs to transfer the position of a cobalt-chromium base into CAD, the workflow relies onscan bodies a IPD CAD libraries. In the supplied CREAS EN brochure, the scan body is presented as a solution forsingle and multiple-unit structureswith an emphasis onprecision, fit and reliabilityand compatibility with both chairside and laboratory systems.
The scan body as the entry point to CAD
When the appropriate libraries are available for the base and implant system, the laboratory can scan the base positions, assign the correct STL components and design the restoration without manually approximating the interface. From a workflow perspective, this makes the transition from a conventional base to a digitally defined component much clearer.
Single / multipleChairside and laboratoryAccurate position capture
TECH and LITE libraries: what they mean in practice
TECHis described in the brochure as a high-resolution STL library with optimised, validated ASC options and two cement-gap settings for individualisation.LITEis designed for simpler workflows with standard resolution, simplified ASC options and a default cement gap. The important point for users is that a “library” is not merely a file. It directly shapes how accurately and efficiently the technician can work in CAD.
TECH = high resolutionLITE = simplified workflowASC options
Practical relevance:For cobalt-chromium bases, scanning is particularly useful when the restoration is designed in CAD and then produced either by milling a wax pattern for Co-Cr casting, or by milling a metal framework and joining it to the base. This is where Co-Cr bases connect directly with the topics ofscan bodies a IPD CAD libraries.
Position detection in CAD software
This illustration from the supplied brochure shows why CAD libraries matter in practice: the technician is not working “blind”, but with a defined component, its axis and the correct library selection. This improves confidence when designing the restoration, checking the path of insertion and preparing for manufacture.
Recommended workflow
A practical workflow for cobalt-chromium bases with the corresponding CAD libraries
The sequence below connects conventional and digital scenarios so that the laboratory and clinic can see when to use a scan body, when to work from a CAD library and when to proceed with conventional casting or metal milling.
Indication, compatibility and option selection
First verify the implant platform, prosthetic space, emergence profile and screw-channel direction. Decide whether a straight or angulated Co-Cr base is more appropriate and whether the restoration will follow a predominantly conventional or hybrid digital workflow.
- Verify the implant system and platform.
- For angulated restorations, plan for a TPA screw with access up to 25°.
- Plan access for definitive tightening.
Seat the base and choose the workflow
Seat the base on the implant or analog and decide whether to continue with a wax-up or first capture its position digitally. This is the point at which you choose between the burnout coping and a scan-body plus CAD-library workflow.
- Verify complete, strain-free seating.
- If scanning, use the corresponding scan body.
- Record the selected option for the laboratory.
Scan positions and design in CAD
If libraries are available for the selected system, scan the base positions, assign the correct STL files and design the restoration in CAD. Library quality and the correct choice between TECH and LITE matter at this stage.
- TECH = more detailed STL geometry and broader options.
- LITE = a simpler, faster workflow.
- Verify the path of insertion and screw access.
Manufacturing path A: wax milling, casting and sandblasting
One common route starts with a CAD design or wax-up, followed by wax milling, investing, Co-Cr casting and final finishing. After casting, sandblasting is followed by careful verification of the interface and passive fit.
- Check cleanliness after burnout of the coping.
- After casting, finish only in safe, non-critical areas.
- Sandblasting must respect the sensitivity of the implant interface.
Manufacturing path B: metal milling and joining to the base
The second route uses metal milling of the suprastructure followed by welding or another laboratory joining process to the 1.8 mm vertical section of the Co-Cr base. Control of distortion, joint accuracy and passive fit is critical throughout this pathway.
- Maintain sufficient space for the joint.
- Protect the seating zone and anti-rotational geometry.
- After joining, verify passive fit again on the model and clinically.
Definitive screw fixation, servicing and documentation
Complete the restoration by checking proximal contacts, occlusion, aesthetics and access to the screw channel. Angulated channels use TPA fixation screws with a pentalobular drive and the corresponding RA system instruments.
- Verify secure tightening and future service access.
- Document the screw, base and library used.
- Retain this information for future remakes or servicing.
Editorial note:this six-step workflow is intentionally more detailed than a standard product card because users need more than a marketing headline. They need to understandexactly how the component fits into their own workflow.
TPA / ASC instruments and screws
RA drivers, TPA fixation screws and the service logic of angulated screw channels
For both straight and angulated Co-Cr restorations, the restoration must not only be manufacturable but also safely screw-retained and serviceable later. This section therefore explains the TPA concept in practical terms.
RA / TPA system driver
The illustration shows the type of system driver used for the TPA / ASC concept. The source material specifies lengths of18, 25 and 32 mm, helping the clinician select the instrument according to intraoral access and the spatial constraints of the restoration.
18 mm25 mm32 mm
Why driver length matters
A longer RA / TPA driver improves access to deeper screw channels and when working through larger bridge frameworks. Driver length is therefore not a minor detail; it can materially affect clinical access and handling.
C1030 adapter for connection to a torque wrench
The supplied material specifies anRA-type adapter with a right-angle notch in the shankfor connection to a torque wrench with a 7 mm eye, or less commonly 8 mm. A specific C1030 illustration was not included in the supplied files, so the component is described here in text. The card can be extended with a visual detail when an image becomes available.
TPA fixation screw – bone level

FAQ
IPD cobalt-chromium bases with burnout copings in practice
Detailed answers for laboratories, clinics and CAD/CAM partners, including CAD libraries, scan-body workflows and TPA screws.
When does an angulated option make sense?
An angulated base is useful when the screw-channel exit must be redirected for aesthetics, screw access or the space available within the restoration. Combined with a TPA fixation screw, it gives both laboratory and clinician more practical service access.
What is the role of the POM / Delrin burnout coping?
The coping is used for modelling and waxing. The product materials describe it as a burnout component designed to leave no interfering residue, which is important for clean investing, casting and subsequent finishing of the Co-Cr framework.
Can these components also be used in a digital workflow?
Yes. When the corresponding scan bodies and CAD libraries are available, the base positions can be scanned, the correct library assigned and the restoration designed in CAD. The next stage can be either wax milling followed by casting, or metal milling followed by joining to the base.
How do the TECH and LITE CAD libraries differ for the user?
TECH libraries are designed for more detailed work, with high-resolution STL geometry, validated ASC options and multiple cement-gap settings. LITE libraries simplify the workflow and can suit users who prefer a faster, less complex setup.
What does the recommended workflow with a 1.8 mm vertical height mean?
In laboratory practice, the restoration can be designed and then produced by metal milling, followed by welding or joining to the Co-Cr base at its 1.8 mm working vertical height. Control of distortion, passive fit and protection of the interface during joining are essential.
Why are TPA fixation screws important?
TPA fixation screws with a pentalobular drive allow the restoration to be secured through an angulated screw channel, typically at angles up to 25°. This extends access options when a straight screw channel would be clinically or aesthetically unfavourable.
What should be checked before ordering components or designing the restoration?
Check the implant system, platform, prosthetic space, required emergence profile, straight or angulated screw-channel option, laboratory workflow, library availability, manufacturing strategy and whether the clinic has the correct RA / TPA instrument for definitive tightening.
