Prothesoft® FORTEThe professional long-term solution for complete dentures – permanently soft.
A soft, elastic layer on the inside of the denture: it adapts to the jaw, cushions pressure and lets you keep wearing your familiar denture – instead of an expensive new one.
A long-term solution, not a temporary fix
Soft linings exist both as short-term interim solutions and as permanent restorations. Prothesoft® FORTE clearly belongs to the second category.

Your denture rubs, wobbles or no longer fits properly?
Over the years the jawbone recedes – a completely natural process, much more pronounced in the lower jaw than in the upper jaw. A denture that once fitted well no longer sits properly. Many people know the consequences:
- Pressure points and sore spots on the gums
- The denture moves when eating or speaking
- Denture adhesive becomes a daily stopgap
- Certain foods are avoided
A soft cushion for your denture
Prothesoft® FORTE is a soft, elastic material that is permanently applied to the inside of your denture in the dental laboratory. In the mouth it absorbs a little saliva, becomes supple and adapts snugly to your jaw.
- Comfortable to wear – the soft layer cushions pressure peaks
- Better fit – the material fills small gaps between denture and jaw
- Keep your familiar denture – no new denture needed
- Long-term solution – not a temporary fix, guaranteed durability of 3 years
- More affordable than a new denture
- No surgery – no operation, no implants

Four steps to a soft lining
Ask your dentist
Ask your dentist about Prothesoft® FORTE. They will check whether it is suitable for you.
Impression
At the practice, an impression is taken using your existing denture.
Dental laboratory
The laboratory applies the soft layer. In most cases you are without your denture for only a short time.
Fitting
Your denture is fitted again – with a noticeably softer inner surface.
What patients want to know
Is this only a temporary solution?
No. Prothesoft® FORTE is a professional long-term restoration, not a temporary fix. The material is permanently bonded to your denture in the dental laboratory, stays soft and has a guaranteed durability of 3 years.
Is Prothesoft® FORTE safe?
Prothesoft® FORTE is a Class I medical device under the European Medical Device Regulation (MDR), carries the CE mark and has been in use for more than 20 years. The material is processed exclusively in the dental laboratory.
Is Prothesoft® suitable for every denture?
Prothesoft® FORTE has been developed for complete dentures. Your dentist will assess whether it is suitable in your case.
Will I notice the soft layer?
Most wearers find the soft inner surface comfortable. It matches the shade of the denture and is not visible from the outside.
What does the lining cost?
The cost depends on the treatment at the practice and the work in the dental laboratory. A lining is generally considerably cheaper than a new denture. Patients with German statutory health insurance can generally have it reimbursed every three years. Ask your practice for a cost estimate.
How do I care for the denture afterwards?
Clean your denture as usual. Care instructions can be found in the patient information (German · English).
My practice does not know Prothesoft® yet – what can I do?
Write to us using the contact form. We will be happy to inform your practice or laboratory about the material.
This information does not replace advice from your dentist.

When jaw anatomy sets the limit
With complete dentures, natural bone resorption frequently leads to fitting problems. Atrophy occurs six to seven times more often in the lower jaw than in the upper jaw. Conventional hard relines compensate for this only to a limited extent and can cause pressure points.
Prothesoft® FORTE forms an elastic intermediate layer that absorbs stress peaks and adapts dynamically to the jaw – a non-surgical, cost-effective solution between relining and a new denture.
Not a temporary fix: Prothesoft® FORTE is a heat-cured long-term restoration with a guaranteed durability of 3 years. With German statutory health insurance (GKV), reimbursement is generally possible every three years.
Retention through physics – not adhesive
Prothesoft® FORTE is based on methyl methacrylate and 2-hydroxyethyl methacrylate. Three effects reinforce each other.
Adhesion and cohesion
A retention mechanism forms between the saliva-saturated denture base and the mucosa – comparable to two moistened glass plates that slide sideways but can hardly be pulled apart vertically.
Swelling and clamping effect
Thanks to its microporosity, the material absorbs saliva and swells by up to 13 % in volume. Gaps and voids are filled; in undercut areas a clamping effect with a valve-like seal is created.
Pumping effect and self-cleaning
Under chewing pressure, saliva is continuously absorbed and released. The inner surface of the denture is constantly rinsed.

Four steps to the finished lining
Contents per lining: bottle A with 20 g of liquid base substance (monomer) and bottle B with 3.4 g of powder (peroxide).
Preparation
Take an impression or functional impression, grind out pronounced undercuts, invest and isolate the model. Grind out 1–2 mm of the inner surface of the denture and degrease with acrylic liquid.
Gel preparation
Add all of the powder (B) to the liquid (A), shake vigorously and warm in a water bath until a honey-like, viscous gel forms. Apply evenly.
Polymerisation
Close the flask and press under pressure, remove excess material and polymerise in a water bath.
Finishing
Allow to cool, deflask and leave to dry in air. Finish and polish with conventional tools. Store in a water bath before insertion.
The applicable processing instructions are authoritative.
