METHOD OF DETERMINING DEGREE OF DAMAGE TO INFERIOR ALVEOLAR NERVE IN DENTAL IMPLANTATION Russian patent published in 2010 - IPC A61B10/00 

FIELD: medicine.

SUBSTANCE: invention relates to field of medicine, namely to surgical dentistry and is intended for determination of degree of damage to inferior alveolar nerve in dental implantation. Carried out is measurement of electroexitability (EOD) of tooth pulp on corresponding side of lower jaw and electric potentials (EP) of face skin three times in each of 4 points: in area of mouth corner, chin, in projection of mental and inferior dental foramen of lower jaw, by means of apparatus PARKELL 0624. After that average index of EP is calculated: N=n1+n2+n3+n4/4, where n1, n2, n3, n4 are average values of face skin EP in each of 4 points. If values of teeth EOD indices are 12-25 mcA and face skin EP 45-55 mcA, temporary cessation of nerve conduction, indicating a mild degree of damage is diagnosed; if teeth EOD is 26-50 mcA and face skin EP is 55-80 mcA - injury of nerve segment resulting from compression by dental implant is diagnosed, if teeth EOD is 51-100 mcA and face skin EP is 80-150 mcA, complete cessation of nerve trunk conduction is diagnosed.

EFFECT: method allows to establish trauma nature, determine pathogenetic treatment and thus accelerate process of patients' rehabilitation.
