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.
