Study Notes
Dental Crown Material Thickness and Considerations
- Crown material thickness determines the amount of reduction needed on the tooth for adequate strength and contour.
- Different types of metal alloys require varying thickness for adequate strength: high noble alloy - 0.5mm, semi-precious alloy - 0.3mm, non-precious alloy - 0.1mm.
- Non-precious alloy is not preferred due to safety concerns and lower quality of restoration.
- The choice of material affects the fit and aesthetics of the restoration.
- Opaque porcelain thickness ranges from 0.2mm to 0.3mm, body porcelain from 1mm to 1.2mm, and incisal porcelain up to 1.5mm for esthetic results.
- Dentists and technicians collaborate to choose the appropriate materials for each case.
- It is important for dentists to find skilled and knowledgeable technicians to work with.
- Opting for cheaper overseas labs may result in lower quality restorations.
- Diagrams are used to illustrate the layering and thickness of materials in a dental crown.
- Different types of teeth require different thicknesses for adequate strength and aesthetics.
- The functional cusp of a lower molar requires careful consideration of material thickness for strength and esthetics.
- The dentist plays a key role in guiding the material selection process in consultation with the technician.
