Presentation Transcript
College of Dentistry Al-Mustansiriyah University Introduction to dental material science 2019/2020 Aseel Salman PhD, Prosthetic Dentistry
College of Dentistry Al-Mustansiriyah University Material science The study of the characteristics and uses of various materials, such as metals, ceramics, and plastics that are employed in science and technology Dental material science is the study of composition and properties of dental materials and the way they interact with the environment they are placed in.
College of Dentistry Al-Mustansiriyah University Restorative dental materials are the foundation for the replacement of tooth structure lost by disease and injury The demands for material characteristic and performance range from high flexibility required by impression materials to high stiffness required in crowns and fixed dental prostheses. While, materials for dental implants require integration with bone.
College of Dentistry Al-Mustansiriyah University Characteristics of ideal materials: 1- Biocompatible 2- Mechanically stable and durable, strong 3- Resistant to corrosion. 4- Minimal thermal/ electrical conduction 6- Esthetic 7- Easy to manipulate 8- Adheres to tissues 9- Tasteless and odorless 10- Cleanable/ repairable. 11- Cost- effective
College of Dentistry Al-Mustansiriyah University Characteristics of ideal materials: A more complete understanding of basic principles of materials and mechanics is important for the clinician to design and provide a prognosis for restorations. For example, when considering aesthetics high-caries risk patients long-span fixed dental prostheses implants
College of Dentistry Al-Mustansiriyah University HA has the simple formula Ca10(PO4)6(OH)2, with an ideal molar ratio of calcium to phosphorus (Ca/P) of 1.67 and a hexagonal crystal structure.
