Choi, Kim, Kim, and Cho: The efficacy evaluation of PostPlantTM Calcium in dental implant placement

Abstract

Purpose

The aim of this study was to evaluate the changes in bone density and reduction of time consumed for osteogenesis by PostPlantTM Calcium and to find out efficacy of PostPlantTM Calcium by comparing the group prescribed with PostPlantTM Calcium with the group without PostPlantTM Calcium prescription.

Material and methods

The experimental group of 18 patients with 25 dental implant placement and the control group of 7 patients with 9 dental implant placement were randomly selected from the patients who visited prosthetic department of Dankook University Dental Hospital since July, 2006 (IRB Number : 20060710). The experimental group was instructed to take PostPlantTM Calcium for 6 months after the implant surgery while the control group was instructed not to. Both experimental and control group were assigned for measurement using OsstellTM Mentor and Periotest® and radiographic examination was performed using specifically manufactured Aluminum Step Wedge. The results were compared and analyzed.

Results

1. According to the OsstellTM Mentor measurement, both the experimental and control group showed increase in values as time elapses and the experimental group showed significantly higher rate of increase (P < .05). 2. According to the Periotest® measurement, both the experimental and control group showed decrease in values as time elapses. In addition, greater decrease can be seen in the experimental group but no statistical significance was found. 3. By examining the radiographic images, both the experimental and control group showed tendency of increase in bone density. In addition, greater increase can be seen in the experimental group but no statistical significance was found.

Conclusion

Clinically, taking PostPlantTM Calcium medicine for a long period of time after implant placement is expected for a better prognosis. (J Korean Acad Prosthodont 2010;48:128-34)
