In veterinary literature, in order to achieve a more rigid stabilisation and complication-free recovery, both methods of circular (interfragmentary) and 8-shaped interdental cerclage wiring around the canine teeth are recommended in the treatment of open, infected and dislocated mandibular symphysis separations in cats. This is the only way to counteract craniocaudal and dorsoventral forces acting on the mandibular symphysis. However, this prolongs intraoperative time for the application and removal of cerclage wire, as well as necessitating deep sedation or general anaesthesia for removal. The aim of this study is to present the application stages and efficacy of a new technique (IAISInterdental and Interfragmentary Stabilisation) achieving both interdental and interfragmentary stabilisation in a single operation using only cerclage wire, with no need for extra stabilisation. For this purpose, the authors used the IAIS technique in the treatment of 46 patients presented to the surgery clinic between the years 2007-2015 and diagnosed with mandibular symphysis separation. Weekly post-operative follow-up examinations were carried out and clinical recovery time was evaluated. In conclusion, this new technique may be used effectively in the treatment of dislocated-uninfected and open-infected-dislocated mandibular sympyhsis separations.
