To provide a fixing pin, which can be smoothly stuck into a prepared hole bored in a bone without being broken during fixing a dental guided tissue regeneration membrane, and does not readily drop out but can surely fix the dental guided tissue regeneration membrane after being once stuck, the fixing pin made of a bioabsorbable material for fixing a dental guided tissue regeneration membrane is constructed such that a periphery in an oral cavity inner surface side of a head portion thereof supporting a dental guided tissue regeneration membrane is at least in a smooth curve surface form; and that a thumbtack shaft portion thereof to be stuck into a bone is in a columnar having a conical tip and is provided with two to six ridge portions disposed parallel to the axis of the columnar portion thereof and having a length extending within the bone. |
