What is a denture base material?
Nowadays, most denture bases are fabricated using acrylic resins. The materials are usually supplied as a powder and liquid. The major component of the powder is beads of polymethylmethacrylate (PMMA), which can be added to the liquid (mainly methylmethacrylate monomer) to form a mixture.
What is a denture plate made from?
Dentures are removable false teeth made of acrylic (plastic), nylon or metal. They fit snugly over the gums to replace missing teeth and eliminate potential problems caused by gaps.
What materials are used to make dentures?
Dentures are made from a variety of dental materials including acrylic, nylon, porcelain, resin, or metal. The denture framework is generally made from acrylic, nylon, or metal.
What is the first material used for denture base?
celluloid
John Wesley Hyatt (1868) was credited with preparing the first organic plastic molding compound, which was cellulose nitrate, popularly known as celluloid. In 1870 it was first used as denture base material. The advantages of celluloid were its translucence and pink color….

What are denture base polymers?
The denture base is that part of the denture which rests on the soft tissues and so does not include the artificial teeth. Prior to 1940 vulcanite was the most widely used denture base polymer. Nowadays acrylic resin is used almost universally for denture base construction (Fig. 13.1).
What is denture base resins?
Definition • DENTURE BASE: The part of a denture that rests on the foundation tissues and to which teeth are attached. • RESIN: A broad term used to describe natural or synthetic substances that form plastic materials after polymerization. –
Which material is best for dentures?
According to the National Institute of Health, acrylic resin, or plastic, has become the highest on-demand material for dentures. It fixes perfectly into the desired space. It is also the easiest material to adjust and is more comfortable for the patient.
Are dentures made of porcelain?
Dentures are made of many different materials including composite resin, porcelain, acrylic resin, and acrylic. However, acrylic and porcelain are the most common and are used extensively by denturists for making custom denture teeth.
Which polymer is used in making artificial dentures?
Amongst these, poly methyl methacrylate (PMMA) is a polymer that is most commonly used in dental laboratories (to make orthodontic retainers and dentures and for repair), dental clinics (for relining dentures and temporary crowns), and industry (such as fabrication of artificial teeth) [7,9,10].
What material are dentures most commonly made from today?
What are the properties of denture base resin?
Table 1
| Property/Measure | Units | E-20 |
|---|---|---|
| Flexural strength | MPa | 61.9 C (3.0) |
| Flexural modulus | MPa | 1949 C (83) |
| Water sorption | μg/mm3 | 32.8 C (3.7) |
| Water solubility | μg/mm3 | 3.91 A (0.60) |
What are the different types of denture bases?
Acrylic denture base materials can be classified into different groups according to their method of curing. Generally, there are heat curing materials, autopolymerizing materials, thermoplastic, light-activated, and microwave-cured materials.
Why do you need a base plate for a denture?
Most importantly, a processed base plate is the definitive gingival base for the complete denture. It enables the clinician to evaluate phonetic function and vertical dimension during the try-in appointment and to detect pressure points.
How to create a custom dental base plate?
To create the custom base plate, the custom rugae should be dipped in liquid wax , and dipping should be repeated until the desired thickness is attained . The technician must carefully control the heat from the opposite side of the rugae because the silicone has the tendency to hold heat .
What are the benefits of a base plate?
Another benefit of the processed base plate is that it enables a better evaluation of the denture stability. If the dentist is not satisfied with the suction achieved in the base plate design, a wash-off impression can be executed after the denture tooth setup to get the patient’s approval for the final processing.
