A case report of malignant tumour in mandible is discussed in this paper. The innovative rapid prototyping (RP) assisted customized surgical cutting guide (CSCG) has developed for the accurate resection of the malignant tumour in the mandible. Computer tomography (CT) scan data in DICOM format is utilized for the development of CSCG. Mimics 14.11 used for image processing to develop diseased model. 3Matics 6.0 software is used for the virtual surgical planning (VSP) and computer-aided design (CAD) of customized implant and CSCG. Finally, CSCG developed by using fused deposition modelling (FDM), a technique of rapid prototyping (RP) in ABS material. The testing of the RP assisted CSCG was performed by mutually fixing it on the patient’s diseased model developed by the same RP. This paper describes the novel methodology for the development of the RP assisted CSCG and its application to accurately resect the malignant tumour in the mandible. This approach shows good results in designing and manufacturing of the CSCG. Using advanced tools like VSP, CAD and RP, manufacturing of CSCG for the accurate resection of tumour and placement of customized implant may possible easily in actual surgery.
