Partial Dentures

A partial denture replaces missing teeth while you still have some of your own, and you put it in and take it out yourself. The artificial teeth sit on a base, and the denture holds on to your remaining teeth with small hooks called clasps. Part of the chewing force is carried by the remaining teeth, and part by the gum and the bone beneath it.

We give the general comparison with other types of prosthesis on the dentures and prosthetic dentistry page. Here we focus on the partial denture itself, its types and its place in everyday life.

When is a partial denture worth considering?

• If back teeth are missing: With no tooth behind the gap to carry it, a fixed bridge is not possible. The options are implants or a partial denture.
• If there is more than one gap: Teeth missing in different parts of the jaw can all be replaced with a single denture.
• If implants are unsuitable or not wanted: Because of general health, insufficient bone, a wish to avoid surgery, or timing.
• As a stopgap: While waiting for healing after an extraction, or for implants to fuse with the bone.

For a single missing tooth, especially at the front, a partial denture is not usually the first choice; there, an implant or a bridge is often the more comfortable solution.

Metal framework or flexible?

Partial dentures are classified by the material of their base, and the difference matters more than people expect.

	Metal framework	Flexible (thermoplastic)	Acrylic
Where the load goes	To the teeth, through small rests that sit on them, and to the gum	Mostly to the gum	Mostly to the gum
Clasps	Metal; may show in some areas	Gum-coloured	Wire clasps
Bulk in the mouth	Thin	Moderate	Thick
Repairs and adding teeth	Often possible	Limited	Easy
Typical use	Long-term solution	Patients who want no metal; front areas	Temporary period

For a partial denture that will be worn for years, we usually recommend a metal framework. The rests that sit on the teeth stop the denture from sinking into the gum. Flexible dentures generally lack this support, so over time they settle into the gum, and the bone underneath may shrink faster. A flexible denture is not a bad option, but it should be chosen with its limits in mind.

Is a partial denture without clasps possible?

For patients who do not want clasps to show, there is the precision-attachment partial denture. Crowns are made on the remaining teeth, and small male and female components built into or beside the crowns hold the denture invisibly. The aesthetic result is good, but the supporting teeth have to be crowned, the denture takes longer to make and the attachment parts need replacing over time. Placing a few implants and seating the denture on attachments over them is another way to do without clasps; the details are on the implant-supported prosthetics page.

Advantages and limitations

The strengths of a partial denture are real: the neighbouring teeth are not cut down, or only small seats for the rests are prepared; no surgery is needed; the process is completed in a few weeks; and if you later lose another tooth, a new one can often be added to a metal framework. It also generally costs less than fixed options.

So are its limitations. Chewing efficiency does not match fixed teeth. Plaque builds up more easily on the teeth the clasps touch, and if cleaning slips, decay and gum problems speed up on those teeth. Under the parts of the denture that rest on the gum, the bone gradually thins, so the denture may need relining every few years to make it fit snugly again. This is most noticeable at free ends with no tooth behind them: there the denture sinks slightly when you chew, and that is where looseness is felt first.

How is a metal-framework partial denture made?

1. Examination and treatment beforehand: X-rays are taken; decay and gum problems in the teeth that will carry the clasps are treated first.
2. Tooth preparation and impressions: Small seats for the rests are prepared on the supporting teeth, then a detailed impression is taken.
3. Framework try-in: The cast metal framework is tried in the mouth; we check that it seats fully and that the clasps do not strain the teeth.
4. Tooth try-in: The artificial teeth are set in wax; shade, length and bite are adjusted at this stage.
5. Fitting and adjustment: The denture is fitted, we practise putting it in and taking it out together, and short adjustment appointments follow in the first weeks.

What happens in the first few weeks?

At first your mouth treats the denture as a foreign object: saliva increases, some sounds come out differently and your tongue keeps exploring the edges. These usually ease within a few weeks. If a pressure spot develops, do not file the denture down yourself; we correct it at a short adjustment appointment at our clinic in İzmir, or a local dentist can do it if you are already back home. Push the denture into place with your fingers; do not bite it into position, as this bends the clasps and weakens the grip.

How should you look after it every day?

• After meals, take it out and rinse it with water if you can; brush it at least once a day with a separate, soft brush.
• When brushing, fill the sink with water or lay a towel in it; a dropped denture can break, or its clasp can bend.
• Brush the teeth the clasps hold on to separately and carefully; they are what carry the denture.
• At night, take the denture out and keep it in clean water or a denture-cleaning solution. Do not clean metal-framework dentures with bleach; the metal darkens and deteriorates.
• Have a check-up at least once a year, ideally twice; that is when the fit and the tension of the clasps are assessed.
