Sažetak
Mechanically rotating instruments for bone treatment have the disadvantage of damaging the surrounding bone by the generated frictional heat. Cooling of the instrument cannot avoid this damage completely. Laser systems are an alternative solution for bone removal in the areas of dental implantology, bone surgery and osteotomy. The aim of presented experimental pilot study was the comparison of temperature caused bone surface changes and removed bone volume after bone treatment with the Er-YAG laser and cortical drill. The study was performed on the 10 pig ribs prepared with sagital osteotomy to get two equal parts of the rib. Each part then was separated in equal plates with similar thickness of cortical and spongious bone mutually. The idea was to simulate the height and the width of intraoral autologous bone blocks commonly used in bone management in dental implantology. Calibration of the laser parameters was done. Each plate was treated with the non-contact erbium-YAG laser with a 0.9 mm spot size in a max mode to make bone site within the full thickness of the plate. The other preparation was made next the previously prepared laser site with the 1.0 mm wide pilot drill, commonly used for the fixation screws preparations, at 15 000 rpm, with simultaneous saline irrigation. Surface termical changes were measured with infra-red camera in the whole interval of the bone exposure and preparation period. The removed bone volume for each exposure and preparation was calculated by modified mathematical algorithm. Time of the laser bone exposure was within the 15 seconds, and drill preparation within 60 seconds. The removed bone volume was higher in the laser group, and needed considerably less time, which resulted in minor termical surface changes in comparison with the cortical drill preparation, usually caused by extended preparation time. The possibility of using Er-YAG laser in future clinical cases of bone surgery and dental implantology can be considered efficient without inducing irreversible bone damages.
