All-on-X Conversions, as simple as an overdenture pickup.
Same-day teeth with passive fit and ideal occlusion — verified in the chair, in any workflow.
New to SDC? See how it works →The problem
Every All-on-X workflow produces a denture.
Not every workflow produces a good one.
Every clinician aims for passive fit and accurate occlusion. Not every workflow reliably delivers them, and the gap between aimed-for and achieved costs time, rework and adjustment, even when that cost has been normalized. Whatever your workflow, the conversion is where your best work is most at risk.
Chairside or guided
Large holes, open trays, and a provisional that's compromised before it's loaded.
Both techniques thread Temporary Cylinders through the prosthesis: oversized openings that weaken the provisional and complicate passive fit. Guided surgery solves placement, not the conversion.
Fully digital
Occlusion that isn't verified until the patient is back in the chair, after the design and print time is already spent.
Scan, design, review, print, finish: a long loop with several handoffs. If the occlusion is off at the end, the loop starts again.
What SDC solves
Four problems, one solution.
Smart Denture Conversions (SDC) addresses all four at the source: the conversion itself.
Passive fit
Captured intraorally, not estimated
Closed-tray pickup records TiBase position directly from the patient's mouth — not from a scan or an open-tray approximation.
Occlusion
Don't settle for “close enough”
Getting from “close enough” to ideal is usually slow. SDC captures occlusion intraorally with the patient present, so ideal becomes the standard.
Divergent implants
Parallelism not required
SDC accommodates up to 70° of divergence, so screw channels go where they should, not where Temporary Cylinders force them.
Provisional strength
Stronger from the start
Smaller screw channels mean less structural compromise. The provisional reaches the patient's mouth with its integrity intact.
How SDC works
If you've done an overdenture pickup, you already understand SDC.
01
Prepare the TiBase with a Separable Fastener
The Separable Fastener is loaded into the TiBase, with the PEEK Cap extending through the top. Together they seat onto the multi-unit abutment as one unit.
02
Seat the prosthesis over the TiBases
With acrylic injected, seat the prosthesis over the TiBases. The Separable Fastener fits through a small opening — just large enough for the post, not a full cylinder. Closed tray and passive, exactly like an overdenture pickup.
03
Create screw channels and contour
With the TiBases bonded inside the provisional, follow their path to drill clean, accurate screw channels. Contour and polish as needed for a comfortable fit.
04
Deliver
With the patient still in the chair, confirm occlusion before they leave. Smaller holes, stronger structure, passive fit — and the patient goes home with teeth the same day.

Side by side
Conventional vs. Smart Denture Conversion
Conventional conversion
- Requires parallel implant placement — constrains surgical planning
- Large holes through the prosthesis to accommodate Temporary Cylinders
- Open-tray technique — chairside access required above each implant
- Structural integrity compromised before the provisional is even loaded
- Passive fit is harder to achieve consistently across multiple implants
Smart Denture Conversion
- No parallelism required — screw channels placed in the ideal location
- Small openings only — prosthesis integrity preserved from the start
- Closed-tray pickup — predictable, controlled, like an overdenture
- TiBase bonded inside the provisional — stronger structure, cleaner result
- Passive fit captured intraorally — consistent across all implants
SDC and digital workflows
SDC gives your digital workflow its most accurate input: the mouth itself.
A digital design is only as accurate as the scan it's built on, and no scan fully anticipates the mouth. Tissue, fit and occlusion behave differently in reality than in a model, and the gap only shows at seating. SDC closes it: closed-tray intraoral pickup records fit, passivity and occlusion directly from the patient.
The Prosthesis Scan Body (a reverse scan body) then digitizes that verified provisional, so your file reflects the mouth rather than an approximation of it. One you can reprint with confidence.

The Original
Created by a prosthodontist who wanted to get home on time.
Dr. Brandon Kofford, a board-certified prosthodontist, was tired of going home late after All-on-X cases. He wanted the conversion to feel as clean as an overdenture pickup, and saw the Temporary Cylinder standing in the way. So he engineered it out, and the Separable Fastener became the heart of the SDC protocol.
Read why Dr. Kofford created SDC →
Optimal pull force
SDC requires up to 57% less pull force during pickup — placing significantly less stress on the implant site. Less force means less risk, and a cleaner path to passive fit.
A clean pickup
SDC picks up without releasing radiolucent shards that can interfere with the multi-unit abutment. Cleaner pickup. Safer for the patient. Less to manage chairside.
Patented. Proven.
Protected by patent: original engineering, not iteration on someone else's idea, refined through real clinical use from the first case to SDC 2.0.
What clinicians say
“…you'll wonder why you ever used any other conversion method!”
“I use Smart Denture Conversions because it makes the full-arch process seamless for both my team and my patients. It allows us to deliver beautiful, precise results in less time and with less stress. The consistency and confidence it brings to each case have truly elevated our patient experience.”
Dr. Hunter Dawson
Prosthodontist · Charlotte, North Carolina
“After utilizing full-digital, full-analog, and hybrid digital-analog workflows in my solo private practice, I have found that Smart On X is the most efficient, accurate, and patient-friendly method for delivering same-day teeth to our full-arch patients. In my view, optimal patient care means patients can leave 30-40 minutes after surgery with beautiful, passively fitting, strong and easy-to-clean hybrids that also have ideal occlusion. Smart On X currently enables us to achieve this standard of patient care. If you are already proficient and efficient with fundamental prosthodontic overdenture principles, you'll wonder why you ever used any other conversion method!”
Dr. Nicholas Egbert
Prosthodontist · Draper, Utah
“During [a] live conversion, we encountered occlusal challenges with the initial digital provisional print. Recognizing the issue quickly, we pivoted to a custom denture and Smart Denture Conversion workflow – and it absolutely saved the day. The final delivery the following morning was beautiful, functional, and perfectly aligned. That experience showed every doctor and technician in attendance what flexibility, experience, and great systems can achieve when working together.”

Choose your kit →SDC 1.0 and SDC 2.0
Two versions of the same technology. Both use Separable Fastener Technology and the same closed-tray pickup. SDC 1.0 is the protocol most practices use, and the one this page walks through. SDC 2.0 builds the Separable Fastener into a Pre-Coated TiBase in a polycarbonate shell, so there's no PEEK Cap and no pre-coating step. Both are available.

FAQ
Frequently asked questions
How long does a Smart Denture Conversion take?
With experience, most clinicians complete a conversion in 30 minutes or less — some in as little as 20. Your first case will take longer as you get familiar with the protocol, which is exactly what the Interactive Training Kit is designed for.
Do I need special training before my first case?
No formal prerequisite is required, especially if you're already experienced with All-on-X conversions. SDC introduces some different approaches to a familiar workflow, not a night-and-day departure. That said, we recommend the Interactive Training Kit and our training video series before your first case.
What multi-unit abutments is Smart Denture Conversions compatible with?
Smart Denture Conversions is compatible with the majority of major multi-unit abutments. Check our full compatibility chart for your specific MUA.
What's the difference between Smart Denture Conversions 1.0 and 2.0?
Both use the same Separable Fastener Technology. SDC 1.0 uses a PEEK Cap and Threaded Post inserted into a TiBase, and it's the protocol most practices use. SDC 2.0 builds the Separable Fastener into a Pre-Coated TiBase, which removes the PEEK Cap and the pre-coating step. The training series covers both.
Can I use Smart Denture Conversions in a digital workflow?
Yes — and Smart Denture Conversions can actually improve your digital workflow. Intraoral capture gives you a verified provisional with accurate fit and occlusion, which the Prosthesis Scan Body then digitizes for future reproductions. A more accurate file than designing against a scan approximation.
