Indirect or cast restorations are fabricated in the dental laboratory by technical staff while the restorations are placed by clinicians. Clinicians generally do hold theoretical knowledge of the casting process and casting defects but lack experience of fabrication. This hampers them from having an understanding of a particular casting defect. This article reviews the recent evidence in casting defects and implies their application in clinical practice. The aims and objectives of such a review are to allow clinicians to be in a better position to identify these defects of casting and accordingly take action. The article also presents a brief appraisal of the materials involved and their potential behaviour in causing such defects. The casting technique and the properties of the material that interact during the fabrication of indirect restorations have also been discussed.
