METHOD AND DEVICE FOR LIGATION IN JAW FRACTURE SPLINGTING Russian patent published in 2014 - IPC A61C8/00 A61F5/01 

FIELD: medicine.

SUBSTANCE: group of inventions refers to medicine, namely to dentistry and maxillofacial surgery, and is applicable in jaw fracture splinting. Fragments are reduced under local anaesthesia. A splint is prepared and fitted. Tweezers or a pinch clamp is used to grip a ligature wire at 2-3 cm from its end. The wire is brought out from an oral vestibule into the oral cavity through a dental gap. The clamp is used to grip the oral wire end and to deliver it through the other dental gap into the oral vestibule by surrounding a tooth from distal, lingual and medial sides. The distal ends of the ligatures are bent upwards, while the medial ends - downwards. The arched or braced wire rack with an elastic retainer is used to fix to the skin surface by means of the distal ends to the upper surface, and by means of the medial ends - to a lower lip and a chin. The teeth are splinted with the splints brought out between the wire ligature ends. After splinting, the ligature ends are released from the holders and placed into fixing devices in the form of a cube, a parallelepiped or a sphere, or a cone with two canals on two ends of the tooth enclosing ligature. The fixing devices are moved along the ligatures at 4 mm to 24 mm from the vestibular dental surface and clipped to match an end of the fixing device. Upper and lower ends of the wire ligature of each tooth are rolled clockwise with the fixing devices gripped with the clamp or a needle holder. The ends are bent under to the teeth towards a middle line, on an upper jaw below, and on a lower jaw - above the splint.

EFFECT: by using of ligatures with the fixing devices of various colours and shapes with various groove shapes, the group of inventions enables increasing an ease of use of the ligatures in splinting, ensures correcting the ligatures, reducing a risk of mixing up the ends of the adjoining ligatures, improving a rigidity of fixation and an ease of instrumental grasping before rolling the ligature end and providing a release of the ligatures after the treatment.
