METHOD OF REGISTRATING RIGIDITY OF DENTAL IMPLANTS FASTENING Russian patent published in 2009 - IPC A61C19/04 

FIELD: medicine.

SUBSTANCE: invention relates to field of medicine, in particular to dentistry, and can be applied for diagnostics of supporting-holding apparatus or tooth tissue, surrounding implant. Force is applied to implant, providing change of its position from normal and measurement of angular displacement value. Implant of circular transversal cutting is loaded in point, which is located in the middle of projecting from periodontal part tissues part of implant, by force of pair of forces by means of sinkers, suspended to implant. Angles of its turning by laser pointer, rigidly fastened on implant end are registered on monitor, which is placed in front of implant. Measured are deviations from central line on monitor, which are index of implant displacement from established norm. Coefficient of rigidity of dental implant fastening in bone is determined by mathematic formula. If value of coefficient of rigidity 15≤KJ≤25, conclusion is made that level of rigidity of implant fastening allows its loading with orthopedic construction.

EFFECT: method allows to realise reliable determination of degree of rigidity of dental implant fixation in bone in order to evaluate possibility of its primary, secondary and repeated loading with orthopedic construction.
