Results of using 3-D simulation methods in treatment of midfacial fractures

Keywords: traumatic fractures of the middle zone of the face, bone metal osteosynthesis, open reposition, titanium miniplates, intraoral access, CAD / CAM systems, computed tomography, SLM technology, 3D simulated titanium mini-plates / grids


The article publishes the results of treatment of 27 patients with fractures of the face middle area, of which 14 used standard titanium mini-plates to reposition the fragments, and 13 – individual 3D simulated titanium mini-plates / grids. Before and after treatment, its effectiveness was assessed by the values of the displacements of bone fragments and the index of the visual-analog scale, which allows determining the functional and cosmetic effect of the surgery. It was found that the use of individual 3D simulated titanium mini-plates / grids allowed obtaining in 85 % of patients displacements not exceeding 3 mm. In 72 % of patients in whom standard titanium mini-plates were used, the displacement after surgery was 3.1–6 mm, which is significantly greater than in the group with individual modeling of structures.

On the 7th day after surgery in the first group (treatment with standard mini-plates), the index on the visual-analog scale was 11 (7; 13), which was significantly (p=0.00147) less than before surgery. In the second group (treatment using individual 3D simulated titanium mini-plates / grids) the index on the visual analog scale was 4 (6; 8) points, which was significantly (Z=3.3; p=0.00098) less than before surgery. Comparison of the visual-analog scale of the first and second groups on the 7th day after surgery revealed the presence of significant (U=2.47; p=0.013) differences. The obtained results testify to the greater efficiency of individual 3D modeled titanium mini-plates / grids in comparison with standard titanium mini-plates.

The object of the research: fractures of the middle area of the face. Comparison of the visual-analog scale of the first and second groups on the 7th day after surgery revealed the presence of significant (U=2.47; p=0.013) differences.

Investigated problem: the comparative evaluation of the effectiveness of the middle area of the face fractures treatment using individual 3D simulated titanium mini-plates / grids and standard titanium mini-plates.

The main scientific results: Optimizing the treatment of fractures of the face middle area will help to achieve good cosmetic and functional results.

The area of practical use of the research results: Department of Surgical Dentistry and Maxillofacial Surgery.

Innovative technological product: The proposed technique using individual 3D-simulated titanium miniplates will help to optimize the treatment of patients with traumatic fractures of the face middle area.

Scope of the innovative technological product: Clinical practice.
