Calculation of bone graft volume using 3D reconstruction system

ABSTRACT

Objectives: To obtain bone “bioreplicas” for determining precisely the amount of biomaterial required for boneregeneration procedure. Study design: A case-control comparison with a total sample size of 20 cases, 10 controland 10 test samples. “Bioreplicas” were generated from helical CAT scans with 0.5 mm slices, without 3Dreconstruction or image filters. Bone defects in premolar and molar areas were treated with titanium mesh andxenograft (MP3) combined with resorbable carriers. Time taken to carry out procedures with and without the useof “bioreplicas” (in minutes), discrepancies between the grafts performed with and without “bioreplicas” and bonedefects (mm), and postoperative complications were registered. Results: No significant differences were recordedfor measurements of width and length of bone defect between patient bone and the biological models. Conclusions:The use of “bioreplicas” obtained by rapid prototyping is effective in treatment planning (AU)
