Many prostheses and implants made from polymers have been in use for the last three decades and there is a continuous search for more biocompatible and stronger polymer prosthetic materials. Because both restorations are wet with saliva, an electrical circuit exists with a difference in potential between the dissimilar restorations (Figure 3-10).. For example, there are often accumulations of food debris in the interproximal areas between the teeth, particularly if oral hygiene is poor.. Electrochemical corrosion of the alloy surface underneath the layer of food debris will take place in this situation. Dr. Tenney uses only superior materials and the best dental laboratories, resulting in life-like restorations that are often more beautiful than natural teeth themselves. • • • Resistance of a material to wear Resistance to penetration by an hard object Value of hardness is usually expressed in numbers 11/3/2013 2 3. Optical Properties of Dental Materials Esthetic effects are sometimes produced in a restoration by incorporating colored pigments in nonmetallic materials such as resin composites, denture acrylics, silicone maxillofacial materials, and dental ceramics. Clipping is a handy way to collect important slides you want to go back to later. Chemically, the basic unit of water is a molecule made of two hydrogen atoms and one oxygen atom. The principal aim of Dental Materials is to promote rapid communication of scientific information between academia, industry, and the dental practitioner. Provisional restorations represent an important phase during the rehabilitation process, knowledge of the mechanical properties of the available materials allows us to predict their clinical performance. Dental veneers are thin shells of porcelain or high-quality ceramics that are bonded to the front surface of the teeth. It can be understood by studying a water molecule. Biological properties of dental materials /certified fixed orthodontic courses by Indian dental academy 1. www.indiandentalacademy.com 2. All materials we use consist of trillions of atoms. So thermal conductivity determines how much heat will flow in a material and thermal diffusivity will determine how rapidly heat will flow, And thtats why When the layer dentin between the bottom of the cavity floor and the pulp is too thin, the dentist should place an additional layer of an insulating base. This type of bond is called a hydrogen bridge. Mechanical properties are defined by law of mechanics that is the physical science dealing with forces that acts on bodies and the resultant motion ,deformation, or stress that those bodies experience… 3.

A comprehensive slideshow covering all the basics relating to dental materials and their physical properties. Physical properties of dental materials 1. Thus, the smaller the contact angles between an adhesive and an adherend, the better the ability of the adhesive to flow into and fill in irregularities within the surface of the adherend. The biocompatibility of noble dental alloys is equally important as other physical or chemical properties. This process is known as “Osseointergration.” See our User Agreement and Privacy Policy. : the higher the temperature, the greater the amplitude and, consequently, the greater the kinetic or internal energy. Amorphous materials such as waxes and resins appear solid but actually are supercooled liquids that can flow plastically (irreversibly) under sustained loading or deform elastically (reversibly) under small stresses The ways in which the materials flow or deform when subjected to stress are important to their use in dentistry. The positive hydrogen nucleus is attracted to the unshared electrons of neighboring water molecules. If you continue browsing the site, you agree to the use of cookies on this website. As the surrounding temperature decreases, the level of kinetic energy within individual molecules decreases and the attraction between them becomes more prominent, so that they condense to a liquid form. Dental restorative materials are used to replace tooth structure loss, usually due to dental caries (dental cavities), but also tooth wear and dental trauma.On other occasions, such materials may be used for cosmetic purposes to alter the appearance of an individual's teeth..
