What are dental polymers used for?
What are dental polymers used for?
PMFs such as acrylic acid copolymers are used as a dental adhesive; polylactic acids are used for dental pulp and dentin regeneration, and bioactive polymers are used as advanced drug delivery systems.
What are the properties of polymer materials?
Properties of Polymer Materials
- Density. Ad.
- Thermal expansion. Thermal expansion of polymers is relatively large.
- Thermal Conductivity. The thermal conductivity (K factor) of polymers is very low.
- Chemicals Resistant.
What are polymers and their properties?
Polymers are materials made of long, repeating chains of molecules. The materials have unique properties, depending on the type of molecules being bonded and how they are bonded. Some polymers bend and stretch, like rubber and polyester. Others are hard and tough, like epoxies and glass.
What are the uses of dental materials?
Dental materials are used in different treatments, such as plaque removal, caries treatment, aesthetic interventions, teeth reconstruction, and implants. Indeed, dental material could be made from diverse sources, from metal alloys to shape-memory polymers (SMPs).
What are dental polymers?
Polymers have a major role in most areas of restorative dentistry. The most widely used impression materials are elastomeric polymers. Another major type of polymeric dental material is the composite filling material for anterior teeth. Removable dentures are made from acrylic resin and other polymers.
Are polymers used for dental implants?
Dental implant abutments can be made of different materials including titanium, gold, zirconia, alumina, and polymeric materials. Polyetheretherketone (PEEK) is a high performance thermoplastic polymer that can be used as a dental implant abutment material.
What are the 5 properties of polymers?
Heat capacity/ Heat conductivity. The extent to which the plastic or polymer acts as an effective insulator against the flow of heat.
Why are the properties of polymers important?
Properties of polymers such as high tensile strength, strain, elasticity, toughness determine their uses. More complex polymers form strong bonds, and hence, they are strong enough to withstand high force and pressure. Electrically conductive polymers are used in making electrical devices.
What are the physical properties of dental materials?
Physical properties of Dental Materials are based on:
- The laws of mechanics-Creep & flow , abrasion and abrasion resistance , viscosity.
- Thermodynamics e.g. Thermal conductivity , Thermal diffusivity and Coefficient of thermal expansion.
What are the ideal properties of dental materials?
IDEAL BIOLOGICAL PROPERTIES OF DENTAL MATERIALS Should not be harmful / irritant to pulp and soft tissue. Should not diffuse toxic substances. Should not produce allergic reactions. Should not be carcinogenic.
What is dental polymer?
What are the advantages of polymers in dentistry?
Fundamental knowledge about the properties of the polymers in use in dentistry is an advantage as it provides information relevant to clinical practice. Dentistry, perhaps, has the unique distinction of using the widest variety of materials, ranging from polymers, metal and metal alloys, ceramics, inorganic salts and composite materials.
How many types of dental polymers are there?
Dental Polymers: Applications 2509 Dental Polymers—Dermal initiators, accelerators, or any other additives. The ﬁller system used is typical for a hybrid composite.
What are the character istics of dental polymer?
Dental Polymers—Dermal and curing mode of micro tensile bond strength and nono-indentation of resin cement are very useful character- istics. Recently, the use of HP/HT polymerization to pro-
