[Clinical study of risk management for dental implant treatment--changes of blood pressure and pulse rate during implant surgery under local anesthesia].

The changes of systolic blood pressure (SBP), diastolic blood pressure (DBP), and pulse rate (PR) during implant surgery under local anesthesia were analyzed in 38 normal healthy patients. The results were as follows: 1. SBP significantly increased compared with the preoperative control throughout surgery. 2. DBP did not change significantly compared with the preoperative control throughout surgery. 3. PR increased just after the local anesthesia, and lowered afterward. 4. Both SBP and DBP increased in correlation with age. 5. SBP, DBP, and PR increased in correlation with surgical procedure time. 6. SBP, DBP, and PR increased in correlation with number of implantation. From these results, it was indicated that implant surgery might be accompanied by a risk, even in healthy patients.
