Clinical applicability of robot guided contact-free laser osteotomy—a comparative study in minipigs

Bone tissue ablation with laser became successful only recently: Er:YAG laser systems are used in dentoalveolar surgery. Besides experimentally proven increase of bone healing, major advantages of laser osteotomy are the freedom of cutting geometries and the high accuracy given by the cutting width of 200 μm. These advantages can be effective only when the system is coupled to a robotic guidance. Due to the size of laser systems and surgical robots, a merge leads to an unergonomic setup hindering a routine use in an OR setup. In this work we present first experiences with an integrated miniaturized laser system mounted on top of a surgical light-weight robotic arm. The computer-assisted and robot-guided laser osteotome was used in an OR environment to create different shapes of defects in the mandible of 6 minipigs. Similar defects were created on the contralateral side by piezo osteotome and conventional drill. Geometric accuracy and bone healing were compared. It was shown that the miniaturized robot-guided laser osteotome can be ergonomically integrated into the OR setup without hindering surgeon’s range of motion. The computer-assisted and robot-guided laser osteotome is proved to be a suitable device for all kinds of ostetomies requiring a high accuracy and individual shape.
