Three-dimensional (3D) planning has changed the way orthognathic surgery is approached. Today, it is possible to study each bone structure in detail, simulate jaw movements before entering the operating room, and design personalized guides that increase precision. This technological evolution allows for more predictable treatments, always under the direction and guidance of the surgeon.
Orthognathic surgery corrects alterations in the position of the upper jaw (maxilla) and lower jaw (mandible) that affect the bite, facial harmony, and in many cases, also breathing. Traditionally, planning for this intervention was based on two-dimensional radiographic studies and physical models. And, while they were quite effective, they offered a limited view of a complex, three-dimensional anatomy. Therefore, the incorporation of 3D digital diagnosis has represented a decisive advance in surgical analysis, planning, and execution.
What Does 3D Planning Consist Of?
The process begins with obtaining high-resolution imaging tests and intraoral digital scans. This data is used to generate an exact three-dimensional virtual model of the patient’s facial skeleton and dental occlusion. This allows for a detailed study of the relationship between bones, teeth, and soft tissues, which is different in each case.
On this virtual reconstruction, the surgical team can simulate the necessary movements of the maxilla and mandible with millimeter precision. Different scenarios are analyzed until the optimal position that balances function and aesthetics is defined. This phase is especially relevant in complex cases such as facial asymmetries, open bite, retrognathia, or mandibular prognathism.
Furthermore, once the surgical plan is defined, it is possible to design surgical splints and personalized guides that are subsequently manufactured using 3D printing technology with high-quality biomedical materials. In certain reconstructive procedures, custom titanium plates can also be created, optimizing their anatomical fit. This set of techniques helps to accurately transfer what was planned in the digital environment to the operating room.
It is important to note that, in most cases, the treatment is integrated into a combined approach with orthodontics before and after the intervention. Coordination between the orthodontist and surgeon is vital to achieve a stable and lasting occlusion.
More Precision, More Safety, Better Results
The main advantage of 3D planning is precision. By working on an exact virtual model, uncertainties are reduced and margins of error are minimized. Thus, the surgeon can anticipate bone interferences, evaluate facial symmetry from different angles, and foresee how skeletal changes will influence the patient’s profile.
This simulation capability improves the predictability of the result, both functionally and aesthetically. From a functional point of view, it allows for optimizing the bite and, in certain cases, enlarging the airway space in patients with respiratory disorders of anatomical origin. From an aesthetic point of view, it facilitates a detailed analysis of facial proportions and balance, always seeking naturalness and harmony.
At Clínica Birbe, digital planning is part of a comprehensive protocol that combines advanced technology, its own operating room with the most advanced equipment, and a highly qualified multidisciplinary team. Dr. Birbe has over 25 years of experience in oral and maxillofacial surgery and is a diplomate of the American Board of Oral and Maxillofacial Surgery, an exceptional accreditation in Spain. His track record in orthognathic surgery and facial reconstruction means that many patients from all over Spain and abroad choose us for this type of treatment.
Technology is a Tool, Not a Substitute for the Surgeon
Having explained the advantages of technology, it must be emphasized that by itself it does not guarantee success. The software does not decide the treatment nor replace human experience. It is the surgeon who, ultimately, determines the appropriate movements, the thickness and position of the plates, the surgical strategy, and the adaptation to each real situation. Three-dimensional planning is an extremely valuable tool, but it requires deep knowledge, aesthetic judgment, and medical responsibility to be applied correctly. This is why responsible use of it is essential.
3D planning is not a technological fad, but a coherent evolution towards more accurate and personalized surgery. By allowing each intervention to be studied, simulated, and designed before it is performed, it improves the safety and predictability of orthognathic surgery. When this technology is integrated into expert hands and within rigorous protocols, the patient always benefits from the good results.
