An intraoral insertion path visualizer is applied in the field of oral fixed prosthesis, especially in fixed prosthodontics requiring that abutments share the same insertion path. The intraoral insertion path visualizer mainly comprises two parallel visualizing rulers, a crossbeam and a handle. One of the visualizing rulers is disposed at an end of the crossbeam and is rotatable, and the other visualizing ruler is disposed at the other end of the crossbeam and can slides in a sliding groove in the crossbeam. The handle is flat so that the handle is convenient to grasp. The intraoral insertion path visualizer is characterized in that: during a visualizing process, the sharp end of one of the visualizing rulers is disposed at the shoulder of an abutment and the sharp end of the other visualizing ruler is disposed at the shoulder of another abutment, and therefore the same insertion path of the abutments can be visualized. One of the visualizing rulers is fixed relatively and the other visualizing ruler can be adjusted by allowing the visualizing ruler to slide along the crossbeam according to the different distances between the two abutments. The two visualizing rulers are both rotatable so as to suit each axial surface of the abutments.

The utility model relates to a bone taking drill for the tooth implantation surgery and a bone chip collector. The bone taking drill comprises a supporting member with a buckle part at one end and a tubular bone cutting drill with a plurality of cutting edges at the end part, wherein guiding-in ports by which cutting objects can be guided into an inner cavity of the tubular bone cutting drill are arranged among the cutting edges. The bone taking drill is characterized in that a bone chip collector composed of a tubular body and a one-way valve fixedly mounted at one end of the tubular body is arranged in the tubular bone cutting drill. When the bone taking drill for the tooth implantation surgery and the bone chip collector are in use, after the cutting objects are guided into the inside of the tubular bone cutting drill by the cutting edges of the tubular bone cutting drill through the guiding-in ports, the cutting objects entering the tubular bone cutting drill can act on the one-way valve and impel the one-way valve to be open for extruding the cutting objects into the bone chip collector. The bone taking drill integrates the cutting and the collecting; and the bone chip collector can be taken out of the tubular bone cutting drill through taking down the tubular bone cutting drill from the supporting member so as to greatly facilitate the operation. The bone taking drill has ideal use effect and also has high application value with regard to clinical operation.
