DEVICE FOR PROVIDING SAFETY USING IN STOMATOLOGY (VERSIONS) AND DEVICE AND METHOD OF PRELIMINARY CALIBRATION AND STORAGE OF DATA RELATING TO DEPTH OF DRILLING Russian patent published in 2006 - IPC A61B17/16 A61C1/08 A61C3/02 

FIELD: dental surgery; dental implantology.

SUBSTANCE: device for providing safety in dental surgery has drilling tool and stopper intended for mounting depending on required depth of drilling and for preventing penetration for depth being deeper than required one. Drilling and tool have aids for direct and indirect communication and interaction aids intended for movement transformation. Movement transformation takes place when device is in action. Drilling tool is withdrawn backward relatively direction of drilling by means of action of mentioned aids as soon as front part of stopper makes contact with adjacent surface. According to proposed version, device is provided with aid for preliminary calibration and storage of data related to depth of drilling. Aid has standard member in form of transparent calibration member, and piston. Piston can be provided with rod. Top surface of the member corresponds to zero mark at calibration. External diameter of member equals to external diameter of stopper. Method of preliminary calibration and storage of data on depth of drilling is based upon usage of reference member to surface of which reference member the front surface of stopper is pressed against. Piston is pressed down inside case by means of devices which relate drill with stopper. End of working part of drill makes pushing influence on piston until top surface of piston finds its position at calibration mark.

EFFECT: increased safety of operation.
