ANSWERS

How long does a denture last?

A conventional full denture lasts 5 to 7 years before relining or remake is needed, and 7 to 10 years with attentive care. Implant-retained overdentures stretch to 10 to 15 years on the prosthetic side, though the attachment components (locator inserts, O-rings) need swap-out every 6 to 24 months.

THE SHORT ANSWER

THE FULL PICTURE

Why it works this way

What actually wears out first

Most dentists assume the acrylic or the teeth wear out first. They don't, usually. The American College of Prosthodontists (2024 clinical guidance) reports that resorption of the residual alveolar ridge is the dominant failure driver for conventional dentures, with measurable bone loss starting within the first year post-extraction and continuing at roughly 0.1mm per year on the mandible thereafter. The denture base stays intact. The mouth underneath it changes shape.

When should a patient get a reline instead of a new denture?

If the prosthetic teeth are intact, occlusion is still functional, and the complaint is fit or looseness, a chairside or laboratory reline at year 3 to 4 is the right call. Dani Dental turns laboratory relines in 5 business days. If the teeth are worn flat, the vertical dimension has collapsed, or esthetics no longer match the patient's face, a full remake is the answer. The general rule: relines fix fit, remakes fix function and esthetics.

Do implant-retained overdentures really last longer than conventional dentures?

Yes, on the prosthetic side. The acrylic base of an implant-retained overdenture lasts 10 to 15 years versus 5 to 7 for conventional, because the implants prevent the ridge resorption that destroys conventional denture fit. The trade-off is the attachment components (locators, O-rings, bar clips) need replacement every 6 to 24 months. The total cost of ownership over 15 years still favors the implant-retained option for most patients who can be candidates.

What is the remake rate dentists should expect from a quality lab?

Industry remake rates on removables run 5 to 8% across general commercial labs. Dani Dental's documented remake rate on removables is under 2.5%, attributable to the named-technician case ownership model and the mandatory try-in verification stage before final processing. When evaluating a lab partner, ask for the documented remake rate in writing, and ask whether the technician who fabricated the case is reachable by direct line during the seating appointment.
