It is known that hydroxyapatite ceramics have a good biocompatibility and unite directly to the bone tissue. The authors reported it's promising properties as a bone substitute by animal experiments.<BR>In this paper, four cases are reported in which hydroxyapatite ceramics were used as an artificial bone. Three types of hydroxyapatite ceramics-dense, porous and particulate-were used for augmentation of deficient alveolar ridges and for implantation to partial bone defects. There has been no adverse reaction of hard and soft tissues such as surrounding bone resorption or inflammatory changes of soft tissues.<BR>However, it is considered necessary that long-term follow-up studies of these cases and further basic studies on degradability of hydroxyapatite ceramics and on cases to which respective shapes of ceramics can be suitably applied will be carried out in the future.
