TOOTH MODEL, TEETH MODEL FOR DENTAL TREATMENT EXERCISE, DENTAL TREATMENT EXERCISE DEVICE AND ROBOT FOR DENTAL TREATMENT EXERCISE

摘要

PROBLEM TO BE SOLVED: To provide a tooth model that is hard to cause disconnection, and is superior in mass productivity and handling ability, and also is superior in detachable workability to the teeth model for dental treatment exercise, and provide a teeth model for dental treatment exercise that is hard to cause abrasion or deterioration of a pressure sensing part of the tooth model, and can reliably detect the pressure applied to a pressure sensing part through a gingival model and has superior stability of operation.SOLUTION: A tooth model includes: a dental crown part 2; a tooth root part 3 extended to the lower part of the dental crown part, and embedded in a gingival model; an upper electrode 4 externally inserted in the upper end side of the tooth root part; an upper insulating member externally inserted in the tooth root part, and coming into abutment with the lower surface of the upper electrode; a lower electrode externally inserted in the tooth root part, and coming into abutment with the lower surface of the upper insulating member 5; and a pressure sensing part 12 where a cylindrical pressure sensitive conductive rubber with electrical resistivity changing by pressurization from the outside is covered over an outer circumference of the upper electrode and the lower electrode.SELECTED DRAWING: Figure 3
