Porcelain-fused-to-metal (PFM) restoration is a
type of dental prosthesis introduced since the early 1960s. This
prosthesis is strong, aesthetically satisfactory, and affordable.
This study aims to classify the types of failures observed in
PFM prostheses that were constructed in a dental laboratory
in Misrata, Libya. Data from six months of laboratory
fabrication and clinical observation were collected.
Approximately 12% of the PFM prostheses demonstrated the
following defects: bubbles (31%), fractures and cracks in the
porcelain (25%), chipping (13%), porosity (13%), shade
defects (13%), and fractures in the metal framework (6%).
These defects can impair PFM restorations. Hence, future
studies must determine the cause of these defects and improve
the materials used for dental restorations.
