The diagnosis of jaw bones using X-ray computed tomography (CT) is important to determine placement of dental implants. A Clinico-statistical study were made on 490 cases which applied preoperative dental mutiplannar reconstructing CT (dental MPR) imaging for dental implant treatment in Iwate Medical University Hospital, during a five-year period from 2002 to 2006. The following results were obtained: 1) The 490 cases consisted of 179 males and 311 females. They ranged in age from 16 to 80 years, the average age was 53.6 years old. 2) The largest number of cases were in their 50's and, in most generations, there were more female cases than male. 3) similar cases have been increasing every year. 4) Most patients were referred from other clinics to our hospital. 5) Of the cases that underwent CT scanning more were mandible than maxilla. 6) Implantation prearranged region revealed a predominance of mandible in anterior teeth, and maxilla in molar teeth. 7) The cases that were using diagnostic surgical stents increased in the first three years, but were constant afterwards.
