치과용 임플란트 식립 후 초기 적외선, 초음파 자극치료에 따른 골유착 변화에 관한 연구 = Study on Changes in Osseointegration Following Early Infrared and Ultrasonic Stimulation Treatment After Dental Implant Placement

다국어 초록 (Multilingual Abstract)

In this study, 3 dental implants were implanted in each femur of NZW rabbits, and only the right experimental group was irradiated with 850 nm infrared and 3 MHz ultrasonic waves for 10 minutes every day. After 3 and 6 weeks, a torsional test was performed using a universal testing machine to determine the changes in osseointegration. As a result, in the specimen subjected to 3 weeks, the maximum value of 3.01 MPa was measured in specimen #1, and the minimum value of 1.20 MPa was measured in specimen #1. In the control group, the maximum value of 0.75 MPa was measured in specimen #6, and the minimum value of 0.10 MPa was measured in specimen #4. The average value of specimens #1 to #3 of the experimental group was 1.76 MPa, and the average value of specimens #4 to #6 of the control group was 0.48 MPa. In the third week, among the torsion test results, for the control group, specimens #4 to #6, the specimen with the lowest initial osseointegration progress was measured at 0.10 MPa, and all of the measurement values at a total of 9 sites, including 3 sites for each specimen, were measured below 1.0 MPa. This is a very key part of this study, indicating that the initial osseointegration was very low. On the other hand, for the experimental group specimens #1 to #3, all of the measurement values at a total of 9 sites were measured above 1.0 MPa, and the maximum value was 3.01 MPa, confirming that 850 nm infrared light irradiation and 3 MHz ultrasound irradiation have an effect on improving osseointegration and bone quality with dental implants.
