With standards for aesthetic dentistry higher than ever, patients are increasingly seeking fixed solutions when teeth are missing or damaged. In many cases, however, fixed treatment isn’t feasible. Cost can be prohibitive, anatomical limitations can complicate implant placement, and treatment timelines often make implants or fixed restorations impractical. When those realities collide, partial dentures become the best practical option – and often a necessary part of care. Historically, that option has forced clinicians into compromise. Traditional partial dentures have tended to deliver certain benefits at the expense of others – aesthetics at the cost of comfort, speed at the expense of predictability, or flexibility without precision. Finding a single option that reliably delivers each of these simultaneously has been a longstanding challenge for clinicians.
A digital workflow with a clear gap
For me, those trade-offs had become increasingly difficult to accept. Much of our restorative workflow was already digital, with intraoral scanning and digital fabrication having helped streamline treatment and improve consistency across many procedures. Removable partial dentures, however, remained an exception, disconnected from the digital workflow.
Like many clinicians, we have explored and used a wide range of traditional and flexible partial materials over the years. Cast metal partials provided strength but we found they were heavy, unaesthetic, and often required multiple visits for our patients. Hand-processed acrylic and flexible materials varied significantly in fit and finish depending heavily on the skill of the lab technician. Milled acetyl frameworks improved digital integration but introduced new problems like bulky clasps, poor aesthetics, and frequent patient dissatisfaction. Even flexible materials such as Valplast and Duraflex, while comfortable and visually acceptable, failed to deliver the level of precision we had come to expect from digital workflows elsewhere in our practice.
The biggest problem wasn’t flexibility or comfort, it was inconsistency. Because so much depended on how the appliance was processed, from a clinical standpoint, you never really knew what you were going to get. A lot of the time, even with the more aesthetic solutions, finishing was time-heavy and the end result was purely the result of the skill of the specific lab technician.
In our practice, where most restorative procedures follow a controlled digital pathway, that level of variability stands out. As a result, our attention turned towards exploring solutions that could help improve outcomes while bringing partials into the same digital framework, so our delivery could be more streamlined and consistent from case to case.
Rethinking the removable workflow
I was introduced to Carbon & Keystone Industries’ FP3D material for 3D-printed flexible partial dentures through colleagues working in digital denture workflows. I evaluated the new dual-cure material with a clear objective: to determine whether it could deliver the precision and consistency lacking in other options. Also, choosing a partner lab that can produce flexible partials with FP3D resin is key. In my case, partnering with Absolute Dental Services has been one of the best decisions I’ve made.
In clinical use, FP3D flexible partials immediately demonstrated improved adaptation and uniformity. The adaptation was more precise than anything I had used before. Thickness was uniform, clasps were symmetrical, and the finish was smooth and well-contoured, which is an area where hand-processed solutions often fell short and created challenges for us in the past.
In practical terms, the switch to FP3D also enabled us to remove a persistent bottleneck. A high-quality intraoral scan could be sent directly to the lab, and in most cases treatment was completed within two visits, for scan and delivery, with minimal chairside adjustment. This shift meant fewer variables, more predictable scheduling, and less time spent managing adjustments or remakes. Removable partial dentures could now be reliably 3D printed within the same controlled system and pathways as other digital dental solutions, supporting efficiency without compromising patient outcomes.
Clinical performance where it matters most
The benefits of FP3D became especially clear in cases where time, aesthetics, and patient confidence were critical. In one case, a 65-year-old patient presented with multiple missing maxillary teeth was keen to urgently restore her smile ahead of an extended vacation just two weeks later. Absolute Dental Lab is my go to lab they were able to successfully fabricate and deliver a flexible partial made with FP3D resin within this tight timeframe. The turnaround was key and we were able to fabricate and deliver a definitive partial quickly, with very little adjustment required at insertion. It fit securely and comfortably from the start, which meant the patient could smile confidently not just for her travels, but for years to come.

In another situation, a 74-year-old patient had recently lost her anterior incisors and was struggling with an existing cast metal partial that felt uncomfortable and unstable. Replacing it with a new FP3D partial significantly improved comfort and retention, while allowing our team to turn around the new appliance quickly and minimize the number of patient visits required to complete treatment, compared to previous solutions.
While individual examples such as these illustrate specific outcomes, their significance extends more broadly across the practice. With more than 1,400 patients under our care, the availability of FP3D now allows a large number of patients to access a predictable removable solution as part of routine treatment. Together, these cases begin to illustrate how 3D-printed flexible partials can reshape expectations around consistency, delivery, and patient acceptance looking ahead.

Broad indications, predictable results
Today, our team uses FP3D across a wide range of removable partial denture indications. These include Kennedy Class I through IV cases, as well as immediate and transitional partials placed at the time of extraction, ensuring patients are not left without teeth during longer-term treatment plans. Importantly, its flexibility and strength also allow insertion in patients with challenging undercuts or non-ideal paths of insertion – cases that previously would have required compromises in retention or design.
Importantly, with affordability increasingly influencing treatment decisions, FP3D has also enabled our practice to offer a more accessible removable option without sacrificing clinical performance. The efficiency of the process means I can offer a more price-competitive partial denture while still achieving good aesthetics and reliable retention. For many patients, that makes treatment more achievable at a time when cost is a real consideration, while still delivering a result they’re really happy with.
While I originally trained in traditional tooth-supported design principles, my experience with FP3D has led me to reconsider some of the historical concerns associated with tissue-supported partials. I’ve found that the material’s consistent fit and stability help offset many of those limitations. My experience highlights how advances in material performance can prompt renewed consideration of long-standing treatment approaches.
Clinical confidence and a digital path forward
Since integrating FP3D into my practice, I have seen consistently positive outcomes. Most cases are successfully completed in just two visits, delivery has become more predictable, and patient satisfaction is high, with overwhelmingly positive feedback. As the team’s experience with the material has grown, attention has now shifted toward optimizing outcomes in more challenging anterior cases. For me, these represent the next stage of clinical refinement to expand the range of applications even further.
For dentists who value precision, consistency, and patient acceptance, Carbon & Keystone Industries’ FP3D represents a meaningful advancement in flexible partial dentures. By aligning removable appliances with digital design and 3D-print production, it allows clinicians to restore confidence in a category that has long required compromise. As more clinicians integrate digital workflows into everyday practice, innovative new materials like this point toward a broader shift in removable dentistry – one defined by greater consistency, improved patient acceptance, and fewer traditional compromises.
