For proper fitness of a core portion of an abutment to a patient, a wax model base for an abutment of a dental implant includes an engagement portionengaging with an implant fixture analog embedded in a gypsum model without rotation, a truncated conical portion, a building portionprovided directly on an inner peripheral edge of a ring-like first stepped portion, which is provided on an oral cavity inner side of the truncated conical portion, or through a cylindrical portionhaving a low height to have a conical shape expanding toward the oral cavity inner side and have a cutoff portionon an outer peripheral surface, a cylindrical portionprovided on an inner peripheral edge of a ring-like second stepped portionprovided on the building portion, and a screw holealong a center axis of the base.

Wax model base for abutment of dental implant

There is provided a compound switch suitable for preventing malfunction as a multidirectional switch caused by an unreasonable turning force applied to a slider, improving the switch operability, and simplifying a switch mounting panel surface. When a transverse push-in force is applied to the operating portion, the sliderslides in the push-in direction of the operating portion from a fixed position of neutrality, and hence a contact state corresponding to the slide direction can be obtained. When torque for turning the operating portionaround the axis thereof is applied to the operating portion, the torque is transmitted to an outer basevia the slideretc., by which the outer base, the slider, and the operating portionare rotatingly moved together in the rotation direction of the operating portionfrom the fixed position of neutrality, and hence a contact state corresponding to the rotation direction can be obtained.
