ANSWERS

When should dentures be replaced?

Full and partial dentures should be replaced every 5 to 7 years on average, per the American College of Prosthodontists. Relines extend usable life by 1 to 2 years, but bone resorption, worn occlusion, fractured acrylic, and shade mismatch with remaining dentition are the clinical triggers for replacement regardless...

THE SHORT ANSWER

THE FULL PICTURE

Why it works this way

The 5 to 7 year benchmark, and why it moves

The American College of Prosthodontists publishes 5 to 7 years as the typical replacement interval for a conventional full denture. That number is not a warranty clock. It is a midpoint that assumes average bone resorption rates of 0.1 to 0.2 mm per year in the mandible after extraction, per the longitudinal data summarized in Tallgren's classic 25-year study (still cited in current prosthodontic literature). Patients with faster resorption, bruxism, or xerostomia will need replacement earlier. Patients with implant-retained overdentures hold fit longer.

Can a reline extend the life of a denture instead of replacing it?

Yes, in defined cases. A hard reline addresses tissue-side fit changes from bone resorption and typically buys 12 to 24 months of additional service life when the denture base, occlusion, and teeth are otherwise intact. A soft reline is appropriate for tender ridges but is a shorter-term solution, usually 6 to 12 months. Relines are not indicated when the acrylic is fractured, the VDO has collapsed, or the shade no longer matches the patient's restored dentition. In those cases, replacement is the clinical answer.

Do implant-retained overdentures need to be replaced on the same schedule?

No. The acrylic prosthesis on an implant-retained overdenture follows a similar 5 to 7 year benchmark for the denture base itself, but the locator attachments or bar components wear on a faster cycle. Locator nylon inserts typically need replacement every 6 to 18 months depending on patient load. Bar-retained overdentures hold occlusal stability longer than conventional fulls because bone resorption under the implants is minimal, which extends the functional life of the prosthesis closer to 7 to 10 years in many cases.

What does Dani Dental need from the dentist to fabricate a replacement denture?

For a digital workflow: an intraoral scan of the edentulous arch, a centric relation record, a bite registration at the target VDO, and shade plus mold selection. For analog: a final impression in a custom tray, a CR record, and a face-bow if the case warrants it. If the patient's existing denture is acceptable in tooth position and VDO, send it as a reference. Standard turnaround is 10 business days from approved try-in. The assigned technician is reachable directly during the case.
