2015年5月6日 · One of the repair techniques for this fracture, and for traumatic symphyseal separation, is use of a cerclage wire placed behind the canine teeth. Though most practitioners are familiar with this seemingly basic procedure, there are subtle nuances of placement that will help your patients thrive following …

General “rules” for full cerclage wire application follow: The length of the fracture line obliquity should be at least twice the diameter of the bone. All wires should be spaced approximately 1.0 cm apart, and all wires should be placed at least 0.5 cm from the end of a fracture.

2022年2月17日 · The majority of mandibular symphyseal separations can be treated with a circumferential stainless-steel wire placed immediately caudal to the canine teeth. The technique has been well described. 2,3 A large gauge needle with an inner diameter wide enough to fit the desired size of wire is used to guide passage of the wire (Figure 1).

The wire is applied in an intertwining fashion and tightened to the teeth using a twisting fashion as one would with cerclage wiring. Once the wire has been applied, the teeth are cleaned with an ultrasonic scaler, followed by acid etching with 40% phosphoric acid gel, then rinsed and dried.

2015年10月16日 · Wire is placed in a way to incorporate at least two teeth in front of and two teeth behind the fracture site to allow the teeth to serve as anchors of stability. The most common form of interdental wiring is called the Stout multiple loop.

The initial attempt at repair used a hybrid of interdental and interfragmentary wiring technique. 18 gauge stainless steel circlage wire was placed thru the mandible distal to the break and brought up and around the left lower canine. This failed due to inadequate rigid fixation on the 6th day.

For example, a surgeon may want to place cerclage wires near the tooth root in the ventral mandible to secure good-quality bone at the tension surface, whereas a dentist might prefer an intra-oral technique to preserve the root and relinquish a biomechanically superior location for implant placement.

2011年5月1日 · Wire placement. Orthopedic wire should be flexible enough to permit manipulation through drill holes in the bone and to allow proper tightening. The use of large diameter wire (1.0-1.5-mm) provides the best rigidity for fixation, but also is more difficult to position and properly tighten.

2012年8月1日 · Circum-ferential intraoral wires around the body of the mandible can be incorporated into composite or acrylic in edentulous regions for splint application. MMF9,10,16 stabilizes fractures by temporarily connecting the maxillae …

2016年9月11日 · Symphyseal cerclage wires encircle the mandible caudal to the canine teeth. The wire can be removed once the fracture has healed (generally 6 to 8 weeks) by cutting it with wire scissors where it is exposed behind the canine teeth.
