Abstract
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.
