Bioceram Porous Implant made with alumina was developed by Kyoto Ceramic Company and has been approved for implants.
We have used Bioceram Porous Implant in our clinic since September 1984. For 8 years and a half, we observed the process of 65 implants in 60 subjects. Herein we report about the prognosis of Bioceram Porous Implant. Most of the 61 implants in 56 subjects (18 men and 42 women;aged 20 to 70) have progressed satisfactorily after the operation. And we think that the cause of satisfaction is the quality of maintenance after the operation, but one implant had to be removed because of infection after setting the crown.
We thought that it was caused by the contamination of the biocomposite surface of the implant above the alveolar bone. And 3 implants in 3 subjests were broken. Although this is unusual, we thought it was caused by the ratio of the length of the part in the bone to the length of the part over the bone and fatigue of the implant inflicted by occlusal load for a long term.
