It is a flexible dental prosthesis prepared for individuals with missing teeth and aims to compensate for missing teeth. Flexible dentures adhere to the dental arch due to their structure and metal parts are generally not needed.
You may think that you have lost your old smile due to falling teeth over time. You can choose flexible dentures to regain your smile or dental implant treatments (all on 4, all on 6) in Turkey to provide a more natural look. In this blog post "What are flexible dentures?" we will provide you with a comprehensive information about flexible dentures.
What are flexible dentures made of?
Flexible dentures are usually made of thermoplastic polyamide (nylon)-based materials. These nylon-based materials are considered hypoallergenic, and the thermoplastic gives the denture flexibility and durability, making it more resistant to fracture and helping it better conform to tooth and tissue sub-sections. In addition, the translucent nature of the flexible denture makes the denture look more natural, with a natural gum colour.
Purposes and areas of use of flexible dentures
The areas of use of flexible dentures are as follows:
Partial edentulism:
Flexible dentures are often used in cases of partial dentulism.
Patients with polymethyl methacrylate (PMMA) allergies:
Flexible dentures are a good alternative for patients with PMMA allergies. PMMA is a common material used in traditional acrylic dentures and can cause allergic reactions in some patients. Flexible dentures, on the other hand, are generally hypoallergenic.
Patients with limited mouth opening:
Flexible dentures are a suitable option for patients with limited mouth openings. Their flexible nature facilitates the insertion and removal of the denture into the mouth.
Patients with aesthetic concerns:
Since the hooks (clasps) used in flexible dentures are made of materials that can blend with tooth colour, they eliminate the visibility of metal hooks and provide a more aesthetic smile. This is especially important for patients who do not want the hooks on the front teeth to be visible.
As a temporary or provisional denture:
Flexible dentures can be used as a provisional prosthesis in some cases. Especially in paediatric patients, they can be preferred in cases where a long-term prosthetic solution is not needed.
Unilateral restorations:
Flexible dentures can be used to restore unilateral missing teeth in the mouth.
Patients with large bone spurs (exostoses):
Flexible dentures may be preferred in some cases because they can fit more easily into the spaces under the bony prominences.
Patients scheduled for radiotherapy:
Due to their metal-free structure, they may be a suitable option for patients scheduled for radiotherapy.
As a stress reliever:
Flexible nylon resin adapts to the natural conditions and acts as a stress reliever. Flexible nylon resin also provides stress distribution in removable partial dentures.
Patients with frequent denture fractures:
Patients who experience frequent denture fractures can transition to flexible dentures.
In other areas:
Flexible dentures can also be used in a variety of other areas, such as temporary bridges, occlusal splints, obturators, speech therapy devices, orthodontic appliances, and implant abutments.
Differences between flexible dentures and other types of dentures
- Flexible dentures do not require metal clasps, require less tooth preparation, and are more aesthetic. However, cast dentures are generally more durable and conservative.
- Flexible dentures are more comfortable and reduce the risk of allergic reactions. However, acrylic dentures are easier to repair and less expensive.
- Flexible dentures have less retention than acrylic dentures.
Characteristics of flexible dentures:
The important features of flexible dentures can be summarised as follows:
Flexible denture materials:
The limitations of traditional acrylic or metal-based dentures (brittleness of acrylics, weight of metals, and difficulty of construction) have led researchers to search for materials with more ideal biological and mechanical properties. As a result of this search, flexible dentures based on thermoplastic polyamide (nylon) were developed.
Water absorption and solubility:
The water absorption of flexible dentures is related to the porosity and hydrophobicity of the material. High water absorption shortens the prosthesis's service life. Flexible dentures are usually manufactured from nylon-based thermoplastic materials, with a lower water absorption rate than conventional acrylic dentures. This is due to the absence of a porous surface in the structure of flexible dentures. This makes flexible dentures more durable and reduces the risk of problems such as bad odour and discolouration.
Thermal conductivity:
Prosthetic materials need to transmit the temperature of food to the oral tissues. Low thermal conductivity can lead to heat buildup and surface cracks during prosthetic construction. This may cause the denture wearer to feel the heat of hot or cold foods and beverages less in the oral tissues.
Flexural strength:
The flexural strength of flexible dentures indicates their resistance to the applied load. Flexible dentures have a high flexural strength due to the flexible and impact-resistant nature of the nylon-based thermoplastic material used. This significantly reduces the risk of cracking, fracture, or deformation of the denture compared to traditional acrylic dentures.
Retention:
The resistance of flexible dentures to displacement in the vertical direction is defined as retention. Acrylic dentures have better retention than flexible dentures.
Design and components:
The clasps used in flexible dentures usually approach from the gingival aspect and are designed to wrap around the tooth. These clasps offer a more aesthetic appearance because they do not contain metal. The thickness of the crochet varies according to the material used and the depth of the sub-section. Resin-retaining elements are known as arms, fingers, and wings, and they hold and stabilise RPDs using the undercuts. They are also known as "resin hooks" or "aesthetic hooks".
Impact on the patient:
The retention and stability of dentures are directly related to the impact on patients' oral health. Dentures with inadequate retention and stability may cause chewing, speech, hygiene, emotional state, laughter, sleep, social contact, and work limitations. In addition, dentures that do not fully adapt to the oral structure or have lost their adaptability over time can lead to complaints such as chewing pain, bulky dentures, poor occlusion, and food retention. Retentive dentures resist displacement against a vertical pull, with little or no wobble in horizontal movements. Flexible dentures create a natural feeling in the patient's mouth, as they adapt better to the oral structure due to the material they are made of. Thanks to their soft structure, they minimise gum irritation, which is especially suitable for patients with sensitive gums.
What are types of flexible dentures?
Flexible dentures are produced in many different types in terms of aesthetics and patient comfort. You can find the types of flexible dentures below:
Full flexible dentures:
Full flexible dentures can be preferred in cases where all teeth are missing, in patients at risk of allergic reactions, or in people with sensitive gums. They are lighter than traditional full dentures and put less pressure on the gums.
Flexible partial dentures:
It is especially preferred in patients who have lost front teeth or have several missing teeth in the mouth. are prostheses used in the case. It contains flexible hooks instead of metal retainers, which provides a more aesthetic appearance.
Flexible denture single tooth:
In cases of single tooth deficiency, it is mostly used in the absence of front teeth or molars. It is preferred as a temporary alternative for patients waiting for implant treatment.
Full upper flexible dentures:
It is used when all teeth in the upper jaw are missing
Full lower flexible dentures:
Used in cases where all lower jaw teeth are missing

Are flexible dentures better?
It depends on the individual's needs, oral structure, and expectations. Flexible dentures offer some advantages over traditional acrylic dentures but may not be the best option in every situation.
If the patient's general health is good and there are no special conditions, implant treatment is usually the best treatment. In multiple missing teeth, you can consider implant treatments such as all on 4, all on 5, all on 6 Turkey. One of the reasons why dentists recommend implants is that implants are fixed to the dental arch and function as natural teeth. It is also preferred because of its natural and aesthetic appearance. Although implant treatments are more costly than flexible denture, the lifetime and the comfort it provides to the patient are worth it.

What is the cost of flexible dentures?
Average prices in Turkey excluding additional procedures:
- Partial Flexible Dentures:Average price: 150 - 300 EUR
Full Flexible Dentures: Average Price: 500 - 1.000 EUR
How do flexible dentures stay in place?
Flexible dentures stay in place in the mouth thanks to their design, flexible hooks, and tight fit to the gums.
How long do flexible dentures last?
The lifespan of flexible dentures depends on the quality of the material used, oral care, and how well the denture is used. Generally, flexible dentures can last between 5 and 8 years. However, this can vary depending on individual factors and how well the denture is protected.
