- Learn proper mixing and handling methods.
Introduction to Dental Materials
- Biomaterials: Non-living materials designed to interact with biological systems (e.g., cardiovascular implants, dental restorative materials).
- Biocompatibility: Ability of materials to interact with living systems without adverse effects; essential qualities include being non-irritating, non-toxic, non-allergic, and non-carcinogenic.
- Biomechanics: Studies how biological materials deform under environmental challenges; relevant to dental materials in mastication forces and thermal changes.
Dental Diseases and Restorative Dental Materials
- Restorative materials prevent or repair dental damage from caries, periodontal diseases, and trauma.
- Caries: Caused by bacterial biofilm (plaque) that secretes acids, leading to enamel and dentin dissolution; common in areas where plaque accumulates.
- Periodontal Disease: Affects supporting tissues (gingiva, periodontal ligament, cementum, alveolar bone) around teeth.
Classification of Dental Materials
- Preventive Dental Materials: Includes pit and fissure sealants, fluoride treatments, and mouth protectors.
- Auxiliary Dental Materials: Substances used in fabricating dental prostheses but not part of the final device (e.g., impression materials).
- Restorative Dental Materials: Used for repairing or replacing tooth structures.
Types of Restorations
-
Intracoronal Restorations: Repair damage within the tooth using techniques like direct cavity preparation.
- Types of materials:
- Metal crowns: Suitable for posterior areas where strength is crucial.
- Porcelain fused to metal (PFM) crowns: Combine metal strength with porcelain aesthetics.
- All-ceramic crowns: Strong and aesthetically pleasing, used for anterior restorations.
- Types of materials:
Endodontic Treatment
- Necessary if oral disease or trauma affects the pulp, involving removal of pulpal tissues followed by sealing with restorative materials (e.g., gutta percha).
Replacement of Lost or Missing Teeth
-
Partial Tooth Loss (Partial Edentulism):
- Fixed partial denture (dental bridge): Involves anchor restorations (crowns) on adjacent teeth with artificial replacements (pontics).
- Removable partial denture: Designed to replace multiple missing teeth, made of acrylic and alloy frameworks. Detachable for cleaning, less aesthetic than fixed options.
- Endosseous dental implants: Titanium or ceramic implants placed into bone; allow for indirect restorations.
-
Loss of All Teeth (Edentulism):
- Complete denture: Removable prosthesis that replaces all teeth in an arch, made of acrylic resins that match oral tissue shades.
