METHOD FOR SINUS ELEVATION IN DENTAL IMPLANTATION Russian patent published in 2015 - IPC A61B17/24 

FIELD: medicine.

SUBSTANCE: before and throughout a surgical intervention, a drug exposure is used by introducing the patient into drug sedation and controlled hypotension; to this effect, a patient's systemic blood pressure and body weight are measured; an anxiolytic is chosen; an anxiolytic dose is specified taking into account the measured blood; the anxiolytic is administered with controlling the psychoemotional status and blood pressure through the sedation and the hypotension. An X-ray diagnosis represents an infrared thermography; to this effect, an operative part of the face is left exposed to inspection and inspected continuously and simultaneously with the thermography in the infrared tissue emission spectrum by means of a thermal camera within the range from +26 to +36°C. The thermal camera is mounted opposite a surface of interest in a position to display a colour picture on its monitor and to measure thereby temperatures of the facial skin, mucous membrane, wound surface, surgical instruments, liquids and osteoplastic materials adjoining the tissues within the wound; a blood supply and homeostasis intervention level is stated safe if observing the patient's body temperature and local tissue temperature falling within the normal range; if the parameters remain constant, a sinus elevation operation is performed. If observing the onset of general hyperthermia, a pyrogenic reaction is stated to start, and the patient's body surface is blown with an air flow of room temperature until the body temperature normalises; if the hyperthermia appears to persist, a hypothermic agent is injected. Observing general hypothermia enables stating hypothermic syndrome to start; the latter is prevented by intravenous administration of 10% calcium chloride in an average therapeutic dose; drinking water 500 ml at temperature 42°C is introduced into the stomach; that is combined with laying the patient's body with warming bottles. If the region of interest shows the onset of local hyperthermia within the tissue and the surgical instrument, the latter are irrigated with 0.9% normal saline at temperature 32-35°C, and before creating an annular groove in a bone, an endoscopic probe with a cold blue-purple light source is inserted into a respective side of the nasal cavity; the endoscopic probe is positioned opposite a natural orifice of maxillary sinus, a wall of which is exposed to light uniformly through the above orifice; the probe is fixed; a dental burr is selected to form the annular groove with controlling a tissue illumination under a working tip in diffuse blue-purple light visually continuously; the burr is only immersed until the tissues are coloured blue-purple underneath; Schneider's membrane is separated with controlling its integrity visually continuously in diffuse light; thereafter, the probe is removed.

EFFECT: method provides accuracy, effectiveness and safety of the sinus elevation procedure, provides preserving patient's health with no apprehension, stress, hypertensive crisis, collapse, Schneider's membrane perforation, infectious maxillary sinusitis and facial bruise.
