Cooling irrigation during implant bed preparation is mandatory to avoid overheating. Due to the surgical guide design,external cooling systems do not reach the point of entry of the implant burr. Here, a new technique for irrigation during guided implant surgery for direct rinse of the burr is described. Using CAD/CAM additive technology, a pin of a cooling pipe was designed and implemented in a surgical guide template. The implant bed preparation was performed while the cooling pipe was connected to the surgical guide. During surgery, the irrigation solution was directly rinsing the burr at the point of entry through the irrigation channel. The usage of a cooling surgical guide seems to improve the cooling of the bone during implant bed preparation. This might lead to less thermal affection of bone cells. However, systematic studies are needed to confirm the observations of the presented case report.
