# Utilization of a 3D-Printed Mandibular Jaw for Ridge Reconstruction in Periodontics: A Case Report

## TL;DR

This case report describes using a 3D-printed mandibular jaw to improve surgical planning and reduce complications in periodontal ridge reconstruction.

## Contribution

The novel use of a sterilized 3D-printed jaw to pre-shape a xenograft block before surgery is introduced as a time-saving and less invasive method.

## Key findings

- Using a 3D-printed jaw improved graft shaping and surgical handling.
- Pre-surgery graft preparation reduced operative time and postoperative pain.
- Xenograft blocks can be effectively used with 3D-printed models as an alternative to autogenous grafts.

## Abstract

Three-dimensional (3D) printing is an emerging manufacturing technology in dentistry with a range of applications. Digital dentistry presented in cone beam CT scan radiographs is a revolution that improved surgical outcomes by optimizing accurate diagnosis and analysis of the surgical sites before surgery. A periodontist can modify the treatment plan, surgical techniques, and incision design based on bone defects seen on cone beam CT scans. Block grafting has been a technique of choice when wound stability is required for guided bone regeneration. There was no significant difference between the different surgical procedures for reconstruction and choice should be given to the simpler and less invasive procedure. A xenograft or allograft block can work as an alternative to the autogenous bone block to reduce the surgery time and patient morbidity. Preparation and shaping of block graft during surgery time to match the defect shape can prolong the operative time, reduce the treatment success, and increase postoperative complications. In this case report, a sterilized 3D-printed mandibular jaw was utilized to visualize the defect size and shape. A bovine xenograft block was then prepared, shaped, and adapted on the 3D-printed jaw 30 minutes before the surgery. The block graft was then transferred and well-fitted on the surgical defect. Handling experience was greater and surgery time and postoperative pain were reduced.
