Abstract:
This article focuses on the analysis of modern 3D navigation methods in
orthognathic surgery for precise control of bone fragment positioning. The advantages and
features of navigation systems, their impact on surgical accuracy and postoperative
outcomes are examined. Based on literature analysis, key aspects of intraoperative control
using 3D technologies are presented.
Keywords:
orthognathic surgery, 3D navigation, intraoperative control, bone fragments,
surgical accuracy, digital planning.
INTRODUCTION
In modern orthognathic surgery, the precision of bone fragment positioning plays a critical
role in achieving optimal functional and aesthetic outcomes. The integration of 3D
navigation technologies has opened new possibilities for enhancing the accuracy of surgical
interventions. The relevance of this study is driven by the need to systematize data on the
application of contemporary navigation systems and their impact on the quality of
intraoperative control.
METHODOLOGY AND LITERATURE REVIEW
As part of the study, an analysis of scientific publications was conducted, including articles
from international databases such as PubMed, Scopus, and Web of Science. Special
attention was given to studies describing the application of various 3D navigation systems in
orthognathic surgery.
According to Mamedov et al. [1], the use of navigation systems enables bone fragment
positioning accuracy of up to 0.5 mm. The study by Zhang et al. [2] demonstrated that the
implementation of 3D navigation reduces surgical time by 15–20% compared to traditional
methods.

Petrov and colleagues [3] note that optical systems provide the highest accuracy but require
a constant direct line of sight between markers and cameras. Wilson and Smith [4]
emphasize the advantages of electromagnetic systems in environments with limited visibility.
RESULTS AND DISCUSSION
The integration of modern 3D navigation technologies has significantly transformed the
approach to orthognathic surgery, greatly enhancing the accuracy of bone fragment
positioning. According to research by Johnson et al. [5], the use of next-generation
navigation systems achieves an average error margin of just 0.8±0.3 mm, demonstrating a
significant advantage over traditional methods, where the error margin is 2.1±0.7 mm. This
level of precision opens new possibilities for achieving optimal functional and aesthetic
outcomes.
A particularly important aspect of navigation system implementation is their effectiveness in
managing complex cases of asymmetry and multi-component deformities, as confirmed by
studies conducted by Li et al. [6]. A key advantage of modern navigation systems is their
ability to provide real-time control, allowing surgeons to continuously monitor the position
of instruments and bone fragments relative to the pre-planned surgical outcome. This
significantly improves the predictability of surgical results and reduces the risk of deviations
from the intended plan.
Research by Anderson [7] highlights a substantial reduction in the risk of postoperative
complications with the use of 3D navigation. This technology is particularly valuable in
complex clinical cases requiring exceptional precision in bone structure positioning.
Improved predictability of surgical outcomes contributes to better long-term treatment
results and increased patient satisfaction.
However, as noted by Sidorov et al. [8], the implementation of navigation systems comes
with certain organizational and financial challenges. Significant investments in equipment
and medical staff training are required. Nevertheless, economic analysis suggests that these
costs are ultimately justified by improved treatment quality and a substantial reduction in the
number of revision surgeries. Additionally, the use of modern navigation systems optimizes
surgical time and enhances the efficiency of operating room resource utilization.
In the context of modern orthognathic surgery, 3D navigation technologies have become an
integral component of leading medical institutions, contributing to the standardization of
surgical protocols and the overall improvement of healthcare quality. The accumulated
experience in utilizing these systems underscores their significant contribution to the
advancement of the field and the improvement of treatment outcomes for patients with
various maxillofacial deformities.
CONCLUSION
The application of modern 3D navigation methods significantly enhances the accuracy and
efficiency of intraoperative control in orthognathic surgery. A review of the literature
indicates that the use of navigation systems leads to more predictable outcomes and a
reduced risk of complications. Despite certain organizational and financial challenges
associated with implementation, this technology is becoming the standard in contemporary
orthognathic surgery.
