Surgical repair of mandibular fracture by wiring, PMMA plate and titanium mini plate in dogs

The mandibular fracture repair was done in 17-dogs, which were divided into three groups with five animals in group I and six animals each in group II and III. Three different techniques viz., interdental wiring, titanium mini plate fixation and gentamicin impregnated PMMA plate fixation were evaluated in these groups. The fracture site was most commonly located between 2^nd and 3^rd premolars followed by 3^rd and 4^th premolars on either side. Full free use of mandible on 2^nd day onwards was observed in plated animals and it was observed by 7^th day in animals treated with interdental wiring. The radiographic evaluation showed that fractures treated by PMMA plates healed by osteosynthesis, those treated with titanium mini plate healed by callus formation, and the animals treated with interdental wiring showed the problem of malocclusion and wire loosening and two animals showed uneventful recovery.
