Metal arch splint ligation and fixation

Metal dental arch splinting fixation is used to fix the loose teeth. There are many clinical applications in the Department of Stomatology, and various forms of metal dental arch splints have been designed as needed. There are two types commonly used in clinical practice: stainless steel wire arch splint and aluminum wire arch splint. Treatment of diseases: tooth folding Indication Metal dental arch splinting fixation is suitable for loosening of teeth caused by: 1, tooth contusion. 2, tooth dislocation. 3, the tooth fold. Surgical procedure 1. Equipment preparation (1) Stainless steel snap ring wire: The specification is 0.7 to 0.9 mm (equivalent to SWG 22 to 20). If it is a flexible snap ring wire, it can be burned red on an alcohol lamp to cool it, then softened and then polished. (2) Aluminum wire: The specification should be 1.52.0mm. It can be applied after peeling with aluminum wire. (3) Stainless steel wire for ligation: soft medical stainless steel ligature wire with a specification of 0.30 to 0.50 (corresponding to SWG 25 to 30 G). 2, bending splint Use steel wire or aluminum wire directly in the patient's mouth to directly bend, or apply the mold after bending on the plaster mold. The length should include loose teeth and more than 2 normal teeth at both ends. It is best to perform ligation in the range of the canine or the first molar on both sides and extend to both ends as needed. The bending is completed, and the two ends are bent toward the distal abutment depression of the last tooth to be engaged with the crown surface to reduce the possibility of stabbing soft tissue and preventing the splint from moving to both ends. 3, dental arch splint in place ligation After the dental arch splint is placed at a predetermined location, the ligation wire is ligated one by one, and the ligation wire is placed across the upper and lower sides of the splint. The tip of the ligature twisted knot is bent toward the interdental depression to reduce irritation to the soft tissue.
