In this investigation, 63 In-Ceram crowns were placed in 45 patients in both dental school and private practice settings. The restorations were observed for a period of 24 to 44 moths, with a mean of 37.6 months. Both anterior posterior teeth were treated and occlusal conditions were recorded. One crown fractured, yielding a 98.4% success rate. The single fracture was attributed to crown preparation geometry.
