Abstract: A disinfection box includes a disinfection box unit, ultraviolet disinfection lamps, air dehumidification equipment and ozone generation equipment. The ozone generation equipment is used along with the ultraviolet disinfection lamps to sterilize and disinfect medical equipment to be disinfected inside the disinfection box unit. In particular, as the equipment box is rotatable, the medical equipment to be disinfected can be fully disinfected without any blind spot. In addition, by the collaborative use of the ultraviolet disinfection lamps, the air dehumidification equipment and the ozone generated by the ozone generation equipment, the medical equipment to be disinfected can be sterilized and disinfected quickly and sufficiently in a short time, thereby saving time as well as being sterilized and disinfected without any blind spot.

Abstract: A titanium-mesh umbrella for bone grafting used to combine with conventional implant and to hold bone graft in proper position during dental implant placement procedure, comprises: a titanium metal shank with one end as implant end and the other end having a pin hole at its center to form a mounting portion; a titanium-mesh with its surface having a plurality of screen meshes, wherein said titanium-mesh encircles an area with a diameter in horizontal direction and forms a projecting umbrella surface with a curvature in perpendicular direction, a rough surface being formed on said projecting umbrella surface, said umbrella type titanium-mesh being able to position quickly on the mounting portion of said metal shank to form an umbrella structure. Thus, the titanium metal umbrella can be positioned quickly during dental implant placement procedure, so that the guide tissue membrane can be securely attached, a space for bone graft growing can be maintained, and the operation duration can be shortened.
