The present invention relates to a method for processing his or her own tooth bone graft material, and more particularly, to a method for processing his or her own tooth bone graft material, comprising: (S1) a sterilization and cleansing step for sterilizing and cleansing a tooth extracted； (S2) a fat removal step for removing fat remained on a tooth sterilized and cleansed； (S3) a crown separation step for separating and removing a crown part such that around 5-20 area% is remained on the top of a root part from the tooth on which fat is removed； (S4) a first withdrawal step for withdrawing only the crown part of the tooth cut； (S5) a second withdrawal step for withdrawing the entire tooth undergone the first withdrawal； (S6) a withdrawal material cleansing step for removing withdrawal material from the tooth graft material undergone the second withdrawal； and (S7) a sterilization and packaging step for sterilizing and packaging the tooth graft material cleansed. According to the present invention, a tooth graft site can be provided with shape supporting force such that a part of the crown part is remained on the top of the root part so as to support the tooth graft material, and efficient withdrawing can be made by separate withdrawing of the crown part including plentiful lime so as to facilitate new bone formation of a host tissue, as well as alveolar bone can be precisely placed on a region to be formed such that the formation of alveolar bone can be precisely and rapidly done.
