RPD Design Services for U.S. Dental Labs: Remote Partial Framework CAD

Availability notice — U.S. market. PROCA does not manufacture or ship physical dental products to the United States. Physical production is available in Mexico only. For U.S. laboratories we offer CAD design services with digital file delivery. See nearshore dental CAD design.

Most dental CAD outsourcing is sold as volume: send crowns, get crowns back, cheaper than doing them in-house. Removable partial denture frameworks are a different problem. An RPD is not a shape — it is a mechanism, and the design decides whether the framework seats, whether it stays seated, and how much chair time the dentist loses adjusting it.

PROCA is a dental laboratory and design center in Mexico. We design RPD frameworks for U.S. labs remotely, in your time zone, and deliver the file ready for your printing or casting route.

What we design

• Cast and SLM partial frameworks — full biomechanical design: path of insertion, rests, clasps, major and minor connectors, mesh, finish lines, relief and tissue support.
• Combination and attachment cases — frameworks that work against crowns, telescopic copings or attachments already planned in the case.
• Framework redesign — a case that came back from the mouth and needs the geometry reconsidered rather than re-sent unchanged.
• Design for your route — the same file prepared for printed titanium, cast alloy or another route your lab controls, without tying up your own design hours.

Files come back ready for your route: SLM metal printing, casting or your own bench workflow. If you have house preferences for clasp type, connector width or relief, we learn them once and repeat them.

Why RPD design is the part labs outsource last — and shouldn't

A single crown forgives a lot. A partial framework does not. Every RPD carries decisions that only pay off later:

• Path of insertion decides whether the retentive undercuts you are counting on actually exist along that path.
• Rest seats decide whether load goes down the long axis of the abutment or tips it.
• Major connector rigidity decides whether the framework distributes force or flexes and concentrates it.
• Relief decides whether tissue is supported or blanched.

None of these are visible in a rendering. They show up at delivery, in adjustment time, and in the remakes your lab absorbs. That is exactly why RPD work tends to bottleneck on one experienced designer — and why it is the first thing to break when that person is out, overloaded, or busy with a complex implant case.

Sending RPD design out is not about buying cheap hours. It is about not having your removable output depend on one calendar.

Nearshore: what a shared business day actually changes

Most RPD design outsourcing available to U.S. labs runs from Asia. The price per unit is low and the work can be good. The cost shows up somewhere else: an unclear survey line, a missing antagonist or an ambiguous prescription turns into a full overnight cycle, and a second question turns into two days.

Mexico runs on U.S. time zones, from Pacific to Central. A question about your case gets asked and answered while the case is still open, not tomorrow morning. Over a month of removable work, that difference is measured in cases delivered, not in dollars per unit.

The same-day communication logic matters most when the file is what you need: questions about survey lines, relief or clasp position can be resolved before your production route starts. We wrote the comparison in detail in nearshore vs offshore dental CAD design.

We design removable — and we build the software for it

This is the part no design bureau can copy quickly. PROCA's designers are also building PROCA's own CAD tooling for removable work: framework geometry, printable mesh validation, deviation measurement against the model, and case traceability. The tools come from real cases on our own bench, not from a demo.

Practically, that means when something in a removable workflow is wrong — a mesh that will not print cleanly, a connector that fails a thickness check, a scan that cannot support the design being asked for — we can see it, name it and fix it, instead of returning a file that technically opens.

How a case runs

1. You send the case. Scans or digitized models, antagonist, bite, and what you want the framework to do. The full list is in what to send for an RPD design case.
2. We review before designing. If the case cannot support the design being asked for, you hear it up front — not after the framework is printed.
3. We design the framework and return it for approval, with the design decisions stated so you can check them rather than guess.
4. You produce. Take the file to your own SLM, casting or bench route. PROCA does not manufacture or ship physical products to the United States.

The technical detail of each step is in digital RPD framework design: from scan to SLM-ready file.

Design only, for your metal route

For U.S. labs, PROCA provides the CAD design file and notes. Your lab controls printing, casting, finishing and delivery.

Design only makes sense when you already print or cast frameworks and the constraint is design hours. You keep production in-house and buy back a designer's week.

Full case design makes sense when removable is not worth its own design hours for you: you send the case and receive a framework design ready for your route, keeping your brand, your finishing and your customer. Material considerations are covered in titanium vs cobalt-chrome RPD frameworks.

Design scope is set by complexity and volume before work starts, not by an anonymous unit label — a straightforward Kennedy Class III with two clasps and a full-arch combination case are not the same work.

Frequently asked questions

What files do you need to design an RPD framework?

An intraoral scan or a digitized model of the arch, the antagonist, and a bite relation. Undercuts and finish areas need to be readable. If you already survey your cases, send the survey; if you don't, we establish the path of insertion and tell you what we chose.

Which CAD systems do you work with?

We work in the systems U.S. labs actually run — exocad and 3Shape — and return standard mesh files that open in your workflow. If your production route needs a specific export convention, we set it once and keep it.

Can you match our house design preferences?

Yes, and that is the point of a stable partner rather than a queue. Clasp type, connector dimensions, relief values, finish line placement and mesh style are recorded per account and repeated.

Do you print the framework or only design it?

We design it; you manufacture it. You take the design to your own SLM, casting or bench route. PROCA does not ship physical products to the U.S.

Is this HIPAA-safe? What about patient data?

We work from digital case files, not patient records. Send the scan and the prescription; we do not need patient identifiers to design a framework, and we prefer that you don't send them.

How is pricing structured?

By case complexity and volume. Send a representative case and we scope the CAD design rather than forcing it into a generic price list.
