영문 초록

Presently, Erbium:YAG laser, which is known as laser for osteotomy, is considered to have good resection effects and to bring about minimum thermal damage. Since studies on this has never been done within the country and left as a field still unexplored, I expect to use this study as experimental data on future use of laser on hard tissue. In this report, both surgical bur(diameter 0.5mm carbide roun bur) and Erbium:YAG laser(100mJ/pulse, 10pulse/sec) was used each on the femur of white mouse and after the same amount of osteotomy, the effect of bone healing on the light microscope was observed and comparative study was made histology. The results are as follows : 1. In the first group (1st day, 3rd day), the osteotomic bone portion of the experimental group was irregular with bone resorption and showed more blood cell infiltration, compared with the control group. 2. At 1 week, bone matrix and immature bone was formed in the peripheral and center of the resection area in the control group. But inthe experimental group, more bone formation was initiated in the peripheral than in the center and showed more infiltration of blood cells and inflammatory cells. 3. At 2 week, bone matrix became mature to have similar density with compact bone and showed new formed vessels in the control group. But in the experimental group, bone formation with decreased density was initiated and new formed vessels together with mature bones was observed. 4. At 3 week, mature bone with equal density and regular trabecular pattern was observed in the control group. But in the experimental group, the continuity between the new bone and old bone was rather loose with decreased maturity, but on the other hand, had even bone formation pattern. 5. At 4 week, both the control and experimental group showed perfect bone healing features. From the results above, I can observe that in osteotomy with Erbium:YAG laser bone healing is rather delayed in each step but if, effective percentage of resection could obtained it would be valuable to substitute mechnical bur or saw and bring about much progress and development in the area of oral and maxillofacial surgery. For this, more studies on bone resection and biomechanical strength of bone tissue after bone healing should be done on various animals.
