Innovative use of a stereolithographic model together with the mirror image technique to reconstruct a defect in mandibular continuity

Reconstruction of mandibular defects after resection of a tumour is complicated by anatomical and functional complexities,1 and autografts together with reconstruction plates are among the most commonly used techniques. One shortcoming is the relatively long time spent on bending the plate during the operation, which not only increases the operating time, but also causes metal fatigue of the plate.1,2 Ideal symmetry between the affected and non-affected sides is impossible to achieve, but the use of a stereolithographic model (introduced in the 1980s3), combined with mirroring and superimposition of the non-affected side on to the affected side, is a suitable way to reduce or eliminate these complications.
