An implant component and a part for an implantation instrument require different qualification dossiers. Loads, interfaces, materials and evidence are defined by the device owner. OVEL converts these requirements into criteria for identifying Swiss manufacturers and coordinates their industrial assessment.
01
Screws, fixation parts and interfaces
Bone screws, fixation elements and mechanical interfaces need detailed drawings covering threads, seating surfaces, drive features and edges. Material and finishing requirements follow the approved design dossier.
02
Machined implant components
For prosthesis parts and other implant components, selection considers complex geometry, datums, surface condition and stability after processing. The workshop is assessed against the characteristics actually required by the design.
03
Instruments and guides
Tool holders, guides, handle parts and locking mechanisms are evaluated against assembly, loads and planned reprocessing. Ergonomic or visible surfaces need acceptance criteria distinct from those for functional bearing or seating surfaces.
Material, traceability and process planning
The enquiry should specify exact grade, metallurgical condition, documented provenance and material certificate requirements. Titanium, stainless steels and specialist alloys are not interchangeable without approval. The manufacturer confirms that machining and finishing capabilities suit the dossier.
A process can combine turning, multi-axis milling, secondary operations, deburring, polishing and marking. Critical areas must remain measurable after finishing. The offer identifies surface processing, required protection and responsibility for subcontracted operations.
Inspect after the final operations
A dimension that conforms before finishing may change during polishing or surface treatment. The inspection plan defines the condition in which each characteristic is checked and the methods used for profiles, threads and difficult-to-access surfaces.
Fatigue, strength and other device performance evaluations are separate from dimensional inspection of a component. The device owner defines and validates those requirements. OVEL helps clarify the deliverables requested from manufacturers and specialist providers along the supply chain.
Industrialisation and change management
Pilot production should document a reproducible process and production conditions. Material, supplier and process changes, deviation handling and batch identification are addressed before launch. If ISO 13485 is specified, the manufacturer’s certificate and covered activities are reviewed during selection.
Prepare your manufacturing enquiry
Include revision-controlled drawings, 3D data, intended component use, interfaces, material, critical surfaces, quantities, cleanliness and required reports. OVEL searches for appropriate capabilities and coordinates technical exchanges. Manufacturers and the device owner retain their respective production, design and validation responsibilities.
Yes, provided specifications, acceptance criteria and deliverables are separated for each component family.
Does dimensional inspection demonstrate implant performance?
No. It establishes conformity only for the characteristics measured. Device performance requires the evaluations and validations defined by the device owner.
When should finishing requirements be specified?
At the feasibility stage. Finishing can affect dimensions, surfaces and inspection strategy; adding it late may require a revised manufacturing process.
