PROBLEM TO BE SOLVED: To provide an apparatus for correcting three dimensional space-angle of a drill for a dental hand piece, which is not limited in use by an ambient environment.SOLUTION: The apparatus for correcting three dimensional space-angle of a drill for a dental hand piece corrects the three dimensional space-angle of the drill bit for a dental hand piece for a tooth structure. The apparatus comprises: a first sensing unit 120 for measuring an angle of a housing provided in a fixing unit of the dental hand piece in real-time; a second sensing unit 130 for measuring an angle of a head portion or a jaw in real-time; a calculation unit 140 for primarily correcting the angle of the housing measured by the first sensing unit with an angle of the drill bit, performing real-time secondary correction of the angle of the primarily corrected drill bit with an angle correction value of the drill bit with respect to the tooth structure considering the angle measured by the second sensing unit, thereby calculating the three dimensional space-angle of the drill bit; a setting unit 150 for setting the three dimensional space-angle desired by an operator among the three dimensional space-angles of the calculation unit; and a display unit 160 for displaying an alert message.SELECTED DRAWING: Figure 2 |
