Clinical Studies Of Bone Mineral Density Associated With The Stability Of The Implant

Objective:The purpose of this study was to measure bone density and implant stability parameters, including the resonance frequency analysis measurements implant maximum torque value(ITV) and implant(ISQ), for these related variables were studied, which found that the correlation between them, for the development of implant rehabilitation treatment plan to provide effective help.Methods:Select to Stomatology Hospital of Shanxi Medical Implantation patients mandibular first molar, a total of 30 cases. With the planting site specific data records before surgery by CBCT and use software metering simplant specific BMD, while using Lekholm and Zarb to the subjective judgment of bone mass during surgery, and record the maximum torque value ITV implant after implantation, while using measuring the resonant frequency analyzer initial implant stability factor ISQ values, analyze its correlation with spss18.0 statistical.Results:All implant site mean BMD was 637.93 ± 68.35HU(median is 583.35, from 403.21 to 957.50), the average maximum insertion torque value of 39.23 ± 3.6Ncm(the median is 37, from 33-45) and ISQ values 75.23 ± 10.42ISQ(median is 73, from 60-95). There is a certain correlation between statistically measured variables from the preoperative bone mineral density and implant primary stability parameters.Conclusion:Preoperative accurate measurement of the initial implant stability parameters related to bone mineral density values ??obtained intraoperative acquired a certain degree of correlation, so the use of software that is planted area measuring bone density to predict the primary stability of the implant, is An effective implant surgery to improve the success rate of the method.
