Summary
Virtual surgical planning (VSP) and 3D printed templates effectively managed complex 3D dentomaxillofacial deformities. This approach significantly corrected deformities, achieving satisfactory patient profiles and occlusion.
Area of Science:
- Oral and Maxillofacial Surgery
- Orthodontics
- Medical Imaging
Background:
- Complex 3D dentomaxillofacial deformities present significant clinical management challenges.
- Traditional treatment approaches often require meticulous planning and execution.
Purpose of the Study:
- To evaluate the efficacy of virtual surgical planning (VSP) combined with 3D printed navigation templates for managing complex 3D dentomaxillofacial deformities.
- To present treatment modalities utilized in conjunction with VSP and 3D printed guides.
Main Methods:
- Retrospective analysis of 10 patients with complex 3D dentomaxillofacial deformities.
- Treatment involved combined orthodontics and orthognathic surgery, guided by VSP and 3D printed templates.
- Surgical techniques included bone grafting and distraction osteogenesis as needed.
- Preoperative and postoperative spiral CT scans were used for evaluation, with an average 12-month follow-up.
Main Results:
- Successful intraoperative application of VSP in all 10 patients.
- Significant correction of 3D dentomaxillofacial deformities was achieved.
- Satisfactory aesthetic profiles and functional occlusion were obtained post-treatment.
Conclusions:
- Comprehensive consideration and detailed surgical planning are crucial for managing 3D dentomaxillofacial deformities.
- Virtual surgical planning (VSP) provides reliable assistance in the treatment of these complex deformities.

Procedures for Kidney StonesMedical intervention is necessary when kidney stones or renal calculi are too large to pass spontaneously (typically greater than 5 millimeters) when stones are accompanied by symptomatic infection (such as fever or pyelonephritis), when they impair kidney function, or when they cause persistent symptoms like severe pain, nausea, or urinary retention. Additionally, patients with only one kidney or those who cannot be treated with medical management also require...

Surgical interventions for inflammatory bowel disease (IBD), which includes ulcerative colitis and Crohn's disease, are essential in managing symptoms and addressing complications. The selection of surgical procedures is contingent upon the specific conditions and complications that stem from these illnesses.

01:19Plastic Deformations
472
Plastic deformation represents a fundamental concept in materials science, which explains the irreversible change in the shape of a material when it experiences stress beyond its elastic capability. This phenomenon is important in structural engineering, especially in designing and analyzing cantilever beams—structures that are securely fixed at one end and bear loads at the opposite end. When these beams are subjected to loads within their elastic range, they will return to their...

01:14Plastic Deformations
473
It is essential to understand how structural members behave under plastic deformation when the bending stress exceeds the material's yield strength. This state of deformation permanently alters the shape of the member, in contrast to the linear elastic behavior observed before yielding. The strain at any point in the member is expressed in terms of maximum strain. Notably, the neutral axis, which coincides with the centroid during elastic bending, shifts away from the centroid under plastic...

1.4K
The principle of virtual work states that if a body is in static and dynamic equilibrium, then the sum of all the virtual work done by all external forces and couple moments for any given virtual displacement must be zero.
In static equilibrium, a body can experience an imaginary or virtual movement, such as displacement or rotation. The virtual work done by a force is equal to the dot product of force and virtual displacement in the direction of the force. When it comes to virtually rotating a...
