Area of Science:

  • Materials Science
  • Biomaterials
  • Dental Materials

Background:

  • All-ceramic prostheses are widely used in restorative dentistry.
  • Internal defects such as pores can compromise the structural integrity and longevity of dental restorations.
  • Non-destructive evaluation methods are crucial for quality control in dental materials.

Purpose of the Study:

  • To investigate the internal morphology of all-ceramic prostheses prior to clinical seating.
  • To evaluate the utility of micro X-ray computed tomography (CT) for detecting internal defects.
  • To correlate internal pore characteristics with fracture behavior in failed prostheses.

Main Methods:

  • Experimentally fabricated all-ceramic crowns were analyzed using micro X-ray CT to assess pore distribution and measure layer thickness.

  • Scanning electron microscopy (SEM) was employed to examine fracture surfaces of clinically failed prostheses.

    • Main Results:

    • Micro X-ray CT successfully visualized and quantified the distribution and size of internal pores within the all-ceramic prostheses.
    • SEM analysis revealed a significant correlation between the presence of pores and crack propagation pathways.
    • Veneer and core thicknesses were accurately measured using micro X-ray CT.

    Conclusions:

    • Micro X-ray CT is an effective non-destructive tool for the internal inspection of all-ceramic prostheses.
    • Identifying critical defects, such as pores and their relation to cracks, before seating can enhance the reliability of dental restorations.
    • This technique aids in quality control and can prevent premature failure of ceramic restorations.
