# Preoperative three-dimensional simulation for maxillary anterior bone augmentation with sagittal split ramus osteotomy: a case report

## TL;DR

A 26-year-old man with jaw deformity and bone loss had successful reconstruction using 3D simulation and bone grafting techniques.

## Contribution

The novel use of preoperative three-dimensional simulation to guide bone augmentation and jaw reconstruction in a complex case.

## Key findings

- Three-dimensional simulation enabled precise planning of bone augmentation and jaw surgery.
- Successful dental implant placement and prosthetic treatment followed the bone reconstruction.
- The approach restored both function and aesthetics in a patient with maxillary anterior bone deficiency.

## Abstract

Alveolar bone defects can result from trauma, resection of benign or malignant tumors, congenital anomalies, or periodontitis. These defects require bone augmentation to restore normal occlusal function and improve esthetics. This case report describes a 26-year-old man referred to our hospital with a diagnosis of jaw deformity. A deficiency of alveolar bone and teeth in the maxillary anterior region, caused by childhood trauma, was confirmed. Sagittal split ramus osteotomy was performed, accompanied by bone augmentation of the maxillary anterior region using a custom-made titanium mesh and autogenous iliac particulate cancellous bone and marrow, guided by three-dimensional simulation. Dental implants were placed in the augmented region 4 months later, followed by prosthetic treatment. This case demonstrates successful esthetic and functional reconstruction of a maxillary anterior bone defect and jaw deformity using preoperative three-dimensional simulation.
