Introduction

Orthognathic surgery is one of the most specialized treatment methods in the field of maxillofacial surgery, which aims to correct skeletal abnormalities of the upper and lower jaw.

These abnormalities can cause disruptions in chewing, speech, breathing, and facial aesthetics. Today, with the advancement of new technologies such as virtual surgical design and medical 3D printing, the use of custom splints in orthognathic surgery has significantly increased the accuracy of treatment.

Orthognathic surgical splint

The PTD Orthognathic Surgical Splint is a fully customized guide designed to stabilize the upper and lower jaws during corrective maxillofacial surgery (Orthognathic Surgery). Using 3D imaging, digital design, and 3D printing, these splints allow for accurate transfer of the treatment plan from the virtual to the surgical environment, making treatment outcome predictions more reliable.

Clinical applications

Corrective surgery of the upper and lower jaw and chin
Stabilizing the jaws during surgical procedures
Surgical simulation in specialized maxillofacial software
Accurate transfer of digital treatment plans from specialized software to the operating room
Helps restore facial symmetry, improve profile, and correct malocclusions
Alternative to conventional methods

High accuracy

Reducing errors in jaw position and increasing compliance with the treatment plan

Treatment safety

Preventing jaw deviation or unwanted movement during surgery
