Fifty-seven patients were followed for 2 years and 34 patients for 3 years in a study of the CeraONe system. One implant was lost, resulting in a accumulative success rate of 97.3% at the 3-year examination. All ceramic crowns were seated for 95% of the subjects, and only four of the crowns were classified as failures. Two all-ceramic crowns fractured following trauma, but no crown was fractured when exposed to common bite forces. The bone loss around implants and adjacent teeth was small, and few problems were observed. It was proven that the system achieves good esthetic results and avoids the complications of screw loosening and fistula formation. (Int J Oral Maxillofac Implants 1995;10:702-711)
