ANSWERS

How long does denture relining last?

A hard chairside or lab reline typically lasts 2 to 5 years before the next reline or remake is needed. Soft relines last 1 to 2 years because the resilient liner degrades faster under masticatory load. Lifespan depends on residual ridge resorption, parafunction, hygiene, and base material.

THE SHORT ANSWER

THE FULL PICTURE

Why it works this way

What drives reline longevity

The lifespan of a denture reline is set by three variables: the liner material, the rate of residual ridge resorption underneath, and the patient's occlusal load. A hard acrylic reline, whether processed chairside or returned to the lab, bonds rigidly to the existing base and behaves like the original intaglio surface. Under typical wear it holds fit for 2 to 5 years. A soft reline, using a silicone or plasticized acrylic liner, is designed for patients with thin atrophic ridges, knife-edge mandibles, or chronic sore spots, and trades durability for cushioning. Expect 1 to 2 years before the liner hardens, delaminates, or colonizes with Candida.

When should a denture be relined instead of remade?

Reline when the denture teeth still show acceptable wear, the occlusion is correct, the base is intact, and the fit issue is isolated to the intaglio surface against a resorbed ridge. Remake when the teeth are worn flat, the vertical dimension has collapsed, the base has fractured or been repaired multiple times, or the patient's esthetic complaint is about tooth position. A reline corrects fit; it cannot correct occlusion, VDO, or tooth wear.

Can an implant-retained overdenture be relined?

Yes, and it should be on a shorter cycle than a conventional complete. The soft tissue between Locator or bar attachments takes intermittent load and resorbs at a measurable rate, which changes the fit of the intaglio surface even though the attachments themselves still seat. A soft reline at 12 to 18 months keeps the tissue-borne portion of the load distribution correct and protects the attachments from being overloaded as the only retention element.

What is the turnaround time for a lab reline?

Dani Dental processes lab relines on a 5 to 7 business day turnaround from receipt of the denture at the lab. The case ships back with the technician's direct line on the invoice so the referring practice can confirm material selection or flag a tissue conditioning step before the final reline if the ridge needs to recover first. Rush turnaround is available on case-by-case basis when scheduled with the technician in advance.
