[The application of three-dimensional printing technique combined with three-dimensional reconstruction in mandibular...

Objective:To explore the value and significance of the combination of 3D printing and spiral CT three-dimensional reconstruction in the diagnosis and treatment of common mandibular fractures. Method:Forty patients with mandibular fracture were collected. They were randomly divided into traditional operation group and 3D printing combined with three-dimensional reconstruction operation group. The differences between the two groups were compared according to the operation time and the recovery of fracture. Result:The operation time and trauma of 3D printing combined with three-dimensional reconstruction group were significantly better than those of traditional operation group, and the former was better than the latter （P<0.05）. Conclusion: 3D printing combined with three-dimensional reconstruction operation method realized the concept of individualized, precise and minimally invasive comprehensive treatment, which is worthy of clinical promotion.
