Dental Prosthetics (Fixed and Removable Prostheses)

What Is Prosthetic Dental Treatment?

Prosthetic dentistry, or prosthodontics, replaces missing teeth and restores badly damaged ones so that chewing, speech and facial support return to normal. A gap left by a lost tooth is more than a cosmetic issue: neighbouring teeth can tilt into the space, the opposing tooth may over-erupt, and the remaining teeth carry more load than they were designed for. As these changes progress, the bite can deteriorate and a problem that started with a single tooth may grow into a much broader treatment need.

Prostheses fall into two broad groups: fixed restorations, which are cemented or screwed in place and cannot be removed by the patient, and removable dentures, which the patient takes out for cleaning. Which option suits you depends on how many teeth are missing, the condition of the remaining teeth and jawbone, and your general health — which is why the treatment plan is always established after a clinical examination by the dentist.

Modern prosthodontics has become increasingly precise thanks to intraoral scanners and computer-aided design and manufacturing (CAD/CAM). Digital impressions help reduce fit problems during the laboratory stage. Yet however advanced the technology, the foundation of a successful prosthesis remains the same: accurate diagnosis, careful planning and regular follow-up.

What Are Fixed Prostheses?

Fixed prostheses are attached to natural teeth or dental implants and stay in the mouth permanently. Because they do not move, they feel closest to natural teeth in everyday use, and chewing forces are transmitted in a way very similar to natural teeth, so changes to speech and eating habits are usually minimal.

A crown covers a single, heavily damaged tooth and restores its shape and function; it is also frequently used on root-canal-treated teeth that have become more fragile. A bridge replaces a missing tooth by taking support from the teeth on either side of the gap, which need to be reshaped slightly. With implant-supported crowns and bridges, the neighbouring teeth are left untouched: support comes from dental implants placed in the jawbone.

• Crown: covers a single, heavily damaged tooth and restores its shape and function.
• Bridge: replaces a missing tooth by taking support from the teeth on either side of the gap.
• Implant-supported crowns and bridges: rest on implants placed in the jawbone, so neighbouring teeth do not need to be reshaped.

Which materials are used in fixed prostheses?

Materials include zirconia, all-ceramic (porcelain) and porcelain fused to metal. Highly translucent all-ceramic restorations offer an aesthetic advantage in the front of the mouth, while zirconia is valued for its strength and is widely used in both front and back regions. The dentist selects the material according to the position of the restoration, the chewing forces in that area and the aesthetic requirements.

What Are Removable Prostheses?

Removable dentures are taken out by the patient for cleaning and usually while sleeping. They are generally preferred when many teeth are missing or when there is not enough tooth or bone support for a fixed restoration. Modern acrylic and flexible base materials have made today's dentures lighter and more comfortable than earlier generations.

An important advantage of removable dentures is that a single appliance can replace many missing teeth, and teeth can be added or the denture repaired or relined when needed. On the other hand, their retention is more limited than that of fixed restorations, they require an adjustment period, and they must be cleaned thoroughly every day.

• Complete (full) denture: replaces the entire dental arch when no teeth remain.
• Partial denture: attaches to the remaining natural teeth with clasps.
• Precision-attachment denture: connects to crowned teeth through hidden attachments, so no metal clasps are visible.
• Implant-retained overdenture: snaps onto a small number of implants, which noticeably improves stability, especially in the lower jaw.

What Do Implant-Supported Prostheses Offer?

Implants placed in the jawbone provide strong support for both fixed and removable prostheses. In cases of complete tooth loss, a prosthesis anchored to a small number of implants offers noticeably better retention than a conventional full denture; where a palate-free design is possible, taste perception and speech comfort also improve. For a single missing tooth, an implant-supported crown closes the gap without reshaping the neighbouring teeth.

The All-on-Four treatment, in which a full arch is supported by four implants, is one of the protocols that can provide a fixed solution for complete tooth loss when conditions are suitable. You can read more about how implants work in our article what is a dental implant. Whether an implant-supported prosthesis is appropriate is determined at a clinical examination, taking bone volume, general health and oral hygiene into account.

Fixed or Removable — How Is the Decision Made?

There is no single answer that fits everyone. Fixed restorations offer high comfort and a natural feel but require adequate tooth or implant support. Removable dentures can restore many missing teeth at once and are comparatively easy to clean and repair, though they call for an adjustment period and their retention depends on anatomical conditions.

During the consultation, the dentist reviews the number and position of the missing teeth, the bone volume, gum health, the state of the opposing teeth and your daily habits, then discusses the realistic options with you. Manual dexterity, hygiene habits and personal expectations also influence the choice. The final treatment plan is defined through this examination — not before it.

In some cases the two approaches are combined: for example, a fixed bridge in one jaw and an implant-retained overdenture in the other. What matters is that the chosen solution fits your oral anatomy, general health and daily life.

Who Is a Candidate for Prosthetic Treatment?

People who have lost one or more teeth, whose teeth show advanced structural damage, or whose existing prosthesis has worn out or no longer fits properly can be evaluated for prosthetic treatment. Age alone is not a barrier; the condition of the oral tissues and general health are far more decisive.

In patients with gum disease, periodontal treatment must be completed first, because a prosthesis made over unhealthy gums will not fit or last as it should. Uncontrolled systemic conditions, situations where oral hygiene cannot be maintained, or advanced bone loss may limit certain types of prosthesis; in such cases the dentist plans suitable alternatives together with the patient.

• People with one or more missing teeth
• Teeth with advanced structural loss, fractures or wear
• An existing prosthesis that is worn, loose or ill-fitting
• Complaints related to chewing, speech or appearance

How Does the Process Work at ADEN Dental?

At our clinic in Çukurambar, Ankara, prosthetic treatment starts with a detailed oral examination and, where needed, radiographic imaging. The condition of the teeth, gums and jawbone is assessed, and any decay or gum problems are treated before the prosthetic work begins. Your expectations are discussed, and the realistic options are explained together with their advantages and limitations.

The number of visits and the overall timeline vary with the type of prosthesis: fixed restorations usually require fewer appointments, while removable dentures take slightly longer because of the try-in stages. The exact sequence is clarified in your personal treatment plan. If you are travelling to Ankara for treatment, our guide to dental treatment in Turkey explains how to plan your visit.

• Planning: the suitable fixed and removable options are explained together with their advantages and limitations.
• Impressions and design: conventional impressions or a digital intraoral scan are taken and sent to the dental laboratory.
• Try-in: shape, colour and bite are checked in the mouth and refined where necessary.
• Delivery and follow-up: the prosthesis is fitted and check-up appointments are scheduled to monitor its adaptation.

How Should You Care for a Prosthesis?

The lifespan of a prosthesis depends largely on the quality of daily care and on regular dental check-ups. Care instructions differ between fixed and removable prostheses; your dentist gives you recommendations specific to your restoration at delivery.

Caring for fixed prostheses

Fixed restorations are brushed twice a day like natural teeth; the area under bridge pontics should be cleaned with interdental brushes or super floss. Plaque accumulating where the restoration meets the gumline can lead to gum inflammation and decay of the supporting teeth, so this junction deserves particular attention.

Caring for removable dentures

Removable dentures should be rinsed after meals and brushed at least once a day with a soft brush and a denture cleanser; ordinary toothpaste is not recommended because it can be abrasive. Taking the denture out at night and keeping it in clean water or a cleaning solution allows the underlying tissues to rest.

• Clean the denture over a bowl of water so it is not damaged if dropped.
• Use lukewarm water — hot water can distort the denture base.
• Never let the denture dry out; store it in water or solution when not worn.
• Gently brush the gums, palate and tongue with a soft brush as well.

The adjustment period

Minor speech and chewing difficulties, increased saliva and a feeling of fullness are normal with a new prosthesis and usually settle within a few weeks. Sore spots are relieved quickly with a small adjustment at the clinic — never try to grind or reshape the denture yourself. Regular check-ups every six months help keep both the prosthesis and the oral tissues healthy.

What Affects Long-Term Success?

How long a prosthesis serves you well depends not only on how it was made but also on how healthy the oral environment is kept. Because the jawbone and gums change naturally over time, removable dentures in particular may need periodic relining or renewal. The following factors have a direct impact on longevity:

• Consistent daily oral hygiene and prosthesis cleaning
• Dental check-ups every six months and professional cleaning when advised
• Protective measures such as a night guard if you clench or grind your teeth
• The effect of smoking and uncontrolled systemic disease on tissue health
• Caution with very hard, crusty or sticky foods
