Restorative and Esthetic Dental Materials Chapter 43

Key Terms in Restorative and Esthetic Dental Materials

• Galvanic: Refers to an electrical shock experienced when two metals come into contact.
• Ceramic: A durable, brittle dental restorative material, known for its heat and corrosion resistance.
• Cured: Describes the process of hardening or setting a dental material.
• Adhere: The action of bonding or attaching materials together.
• Palladium: A soft, silvery-white metal similar to platinum, often used in dental alloys.
• Restorative: The process aimed at restoring teeth to their original appearance.
• Pestle: An instrument used within an amalgam capsule for grinding or pulverizing materials.
• Porcelain: A white, translucent ceramic produced by firing and glazing pure clay.
• Esthetic: Pertaining to the artistic and visually pleasing aspects of dental materials.
• Gold: A corrosion-resistant, soft yellow metal used in making indirect dental restorations.
• Viscosity: A measure of a liquid's resistance to flow easily.
• Amalgam: A mixture of metal alloys blended with mercury for dental use.
• Auto-cured: Describes materials that harden through a chemical reaction between two components.
• Microleakage: Small gaps that allow moisture and contaminants to enter around dental restorations.
• Alloy: A blend of two or more metals, often used in dental applications.
• Retention: The ability of a material to hold itself in position.
• Spherical: Pertaining to a round shape, often used to describe types of particles in dental materials.
• Strain: Distortion arising from stress applied to a material.
• Stress: Internal resistance generated within a material in response to external force.
• Filler: An inorganic component that enhances strength and other characteristics in composite resins.
• Trituration: The process of mixing dental materials contained in capsules.
• ADA: The American Dental Association evaluates dental materials for safety, efficacy, and functional resemblance to natural teeth.
• Comprehensive stress: The stress dental materials endure when subjected to chewing.
• Contraction and expansion: Changes in volume that dental materials experience due to temperature variations.
• Amalgam Composition: Silver, tin, copper, and zinc are the primary components of dental amalgam.
• Amalgam Placement: Dental amalgam is typically not used for anterior teeth due to esthetic concerns.
• Copper: Contributes strength and corrosion resistance to high copper amalgams.
• Disposal of Amalgam: Scrap amalgam should be placed in a biohazard bag for safe disposal.
• Amalgamator: A device used for trituration of amalgam materials.
• BIS-GMA: A term that refers to bisphenol A glycidyl methacrylate, commonly used in composite resins.
• Macrofilled Composites: Stronger fillers that are primarily utilized for posterior restorations.
• Light-Curing Factors: Several factors, including type of composite, can influence curing times of light-cured resins.
• Shade Guide: A tool used to match and determine the color of composite resin for dental procedures.
• Final Finishing Step: Involves using a rubber cup and polishing paste for composite resin finishes.
• IRM (Intermediate Restorative Material): Temporary material typically chosen for class II cavity restorations.
• Acrylic Resin: The preferred material for provisional dental coverage.
• Noble Metals: Gold, palladium, and platinum are categorized as noble metals, commonly used for indirect restorations.
• Indirect Restoration: Refers to dental restorations fabricated in a laboratory setting rather than within the mouth.
