Objectives:
The objective of this study was to provide the generalized methodology for design and development of a customized implant and customized surgical osteotomy guide (CSOG) for precise mandibular tumor resection and placement of a customized implant in ablative tumor surgery for accurate mandibular reconstruction.
Methods:
Medical imaging technique, image processing, virtual surgical planning (VSP), biomedical computer-aided design (CAD), and rapid prototyping (RP) were used to develop CSOG and customized implant. A mock surgical test and an experimental analysis were performed on the biomodel (RP assisted diseased model) to check the effectiveness of the CSOG.
Results:
The paired t test showed the statistically significant result with the use of CSOG as compared to the without using CSOG in ablative mandibular tumor surgery.
Conclusions:
A mock test and an experimental analysis proved that, the precise tumor resection and customized implant placement with minimal gap between bone-implant junctions in mandibular reconstruction using CSOG.
