Beyond the Bone: Why Patient-Specific Implants and Mental Health must Align in Orthognathic Surgery

Explore how 3D printing and Patient-Specific Implants are revolutionising orthognathic surgery, and why a landmark study by Prof. Rama (Rajandram et al., 2024) suggests psychological screening is the final piece of the success puzzle.

Orthognathic surgery (OGS) has long been the gold standard for correcting facial dysmorphology, malocclusion, and upper airway obstructions. For the oral and maxillofacial surgeon, success is often measured in millimetres: the perfect alignment of the jaw, the centring of dental roots, and the restoration of function.

However, a recent study titled "Orthognathic surgical success in the eye of the patient: Are we prepared to handle complications emerging from the changing mental health profiles of our patients?" (Rajandram et al., 2024) suggests that surgical precision is only half the battle. As we advance with 3D printing and patient-specific implants, we must ask: are we treating the scan, or the person?

The Changing Face of Patient Psychology

The study highlights a critical shift in the clinical landscape. While surgeons have mastered the biomechanics of osteotomies, the patient’s decision to undergo orthognathic surgery is increasingly influenced by complex social contexts and mental health profiles.

With the update to the DSM-5 (Diagnostic and Statistical Manual of Mental Disorders), the clinical landscape has changed. There is a rising prevalence of neurodivergence (such as ADHD and ASD), body image disturbances (BID), and gender dysphoria. The study points out that while a surgeon may deem a procedure a "success", a patient’s underlying psychological traits—such as rigid expectations or poor coping mechanisms—can lead to postoperative dissatisfaction and "unseen" complications.

How 3D Printing and Patient-Specific Implants Bridge the Gap

At Meticuly, we believe that "personalised" should extend beyond the anatomy. The use of a patient-specific implant is a powerful tool in managing the psychological journey of the patient. Here is how 3D printing technology and Patient-Specific Implants (PSI) act as a bridge between surgical precision and psychological well-being:

1. Predictability as a Psychological Anchor: A primary trigger for postoperative anxiety is the "unknown." By using Virtual Surgical Planning (VSP) and 3D-printed surgical guides, surgeons can show patients a "digital twin" of their expected outcome. This transparency is vital for patients with neurodevelopmental disorders who require clear, inflexible roadmaps for their journey.

2. Reduced Morbidity, Faster Recovery: The study notes that prolonged recovery can exacerbate depression. A Patient-Specific Implant ensures a perfect anatomical fit that "clicks" into place, significantly reducing theatre time and accelerating the healing process. This protects the patient's mental well-being during the vulnerable postoperative phase.

3. Aesthetic Certainty: For patients with body image disturbances, the precision of 3D printing eliminates the guesswork of traditional bone grafting or generic plating, ensuring the "surgical eye" meets the "patient’s eye."

The Need for a Holistic Protocol

The Rajandram review found a significant lack of standardised psychological screening in the OGS field, with only 11 major publications linking specific mental disorders to orthognathic outcomes in the last decade.

The conclusion is clear: as we embrace the future of MedTech, we must not become "oblivious" to the changing mental health prevalence. Surgical success must be defined by the patient’s quality of life and emotional stability.

Conclusion

The future of orthognathic surgery lies at the intersection of technology and empathy. By combining the anatomical perfection of a patient-specific implant with a robust understanding of a patient’s psychological profile, we can ensure that every 3D-printed solution results in a truly satisfied patient.
