Q. Difference between HATCH REAMER and bicon hand reamer
A. The mother of HATCH REAMER development is known as a bicon hand reamer. However, there is a difference in structure and function. Above all, the BICON hand reamer has the principle of lateral deletion by reamer rotation of the maxillary sinus bone, similar to the hatch reamer. After moving forward into the maxillary sinus, the groove is so large that the graft is pulled out too much and the bone graft takes a lot of time.
