A Laser for osteotomy

Project description

An inherent drawback of using mechanical tools for osteotomy purposes is that they are in direct contact with the hard tissue and can transmit unwanted vibrations to the patient. Moreover force and torque applied to the bone may generate 3D movements of the structure that must be compensated in order to maintain overall system accuracy. Furthermore, they are rather bulky and the heat generated by friction may destroy the (degrades the otherwise obtainable) precision of the cut. The best width precision obtained in osteotomy using current surgical procedures is approximately 1 mm and quantitative information does not exist regarding the accuracy of the osteotomy line determined using pre-operative planning tools.The project aimed at using a laser beam to perform the osteotomy (project conducted with AOT and Universitatsspital Basel).
