Study Notes
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.
