title: [Clinical evaluation of amalgam restorations for Class I cavities and Class II. Part II: Cause analysis of unacceptable restorations].
abstract: 627 not acceptable amalgam restorations using conventional alloy were investigated. Main failure was the secondary caries (60%) which was caused more by failures of preparations than by failures of material. New caries led to replacement of fillings in 16%. Fractures of restorations (13%) and unacceptable forms of fillings (9%) had a relative important position. The clinicians can influence 75 percent of the causes. With regard to material improvement, the results are discussed to avoid failures in therapy.
