# In-House Manufacturing of a Translucent Three-Dimensional Model and Surgical Guide for Marginal Mandibulectomy

## TL;DR

This paper introduces a new method for creating a translucent 3D model and surgical guide to improve precision in marginal mandibulectomy surgeries.

## Contribution

A novel translucent 3D model with a colored tumor and a surgical guide for precise resection angle planning in marginal mandibulectomy.

## Key findings

- A translucent mandible model with a colored tumor allows visualization of tumor depth.
- A surgical guide for marginal mandibulectomy includes planned resection angles.
- This method supports accurate surgical planning and personalized surgery based on tumor features.

## Abstract

In recent years, intraoperative surgical guides have been widely used in oral and maxillofacial surgery to navigate the resection sites. However, most of them are designed for segmental mandibulectomy and determine only the anterior-posterior cutting sites. In the case of marginal mandibulectomy, the depth and angle of the resection need to be considered in addition to the anterior-posterior cutting site. This report describes a method for creating a translucent mandible model with a colored tumor that enables visualization of the tumor depth and a surgical guide for marginal mandibulectomy with a planned resection angle. If accurate surgical planning and intraoperative navigation are established using this method, personalized surgery is realized according to tumor features and hence avoids over- or under-resection.
