Summary
Dolphin 3D software
Area of Science:
- Orthodontics
- Oral and Maxillofacial Surgery
- Medical Imaging
Background:
- Skeletal discrepancies require accurate surgical planning.
- Orthodontists and surgeons seek improved prediction methods.
Purpose of the Study:
- To evaluate the accuracy of Dolphin 3D software in predicting soft tissue changes after orthognathic surgery.
- To assess the reliability of virtual surgical planning for double jaw surgery.
Main Methods:
- 20 patients undergoing Le Fort I maxillary movement and bisagittal split osteotomy.
- Preoperative and postoperative cone-beam computed tomographies (CBCTs) analyzed with Dolphin 3D software.
- Virtual surgical simulation compared with actual postoperative outcomes.
Main Results:
- Significant differences observed between predicted and actual outcomes.
- Areas with notable discrepancies include nasolabial angle, soft tissue A point, and subalar area.
Conclusions:
- The accuracy of Dolphin 3D for soft tissue prediction in orthognathic surgery is limited.
- Upper lip and nasal base areas showed the least prediction accuracy.

Dimensional analysis, also known as the factor label method, is a versatile approach for mathematical operations. The main principle behind this approach is: the units of quantities must be subjected to the same mathematical operations as their associated numbers. This method can be applied to computations ranging from simple unit conversions to more complex and multi-step calculations involving several different quantities and their units.

Dimensional analysis is a valuable technique in fluid mechanics for simplifying complex problems by reducing them into dimensionless groups. These groups capture the essential relationships between the variables involved, allowing researchers and engineers to analyze fluid flow without dealing with each variable individually. This approach reduces the number of independent variables, allowing for easier analysis and better understanding of physical phenomena.

Dimensional analysis is a powerful tool that is used in physics and engineering to understand and predict the behavior of physical systems. The basic idea behind dimensional analysis is to express physical quantities in terms of fundamental dimensions such as the mass, length, and time. Derived dimensions like the velocity, acceleration, and force are derived from the combinations of these fundamental dimensions.

The concept of dimension is important because every mathematical equation linking physical quantities must be dimensionally consistent, implying that mathematical equations must meet the following two rules. The first rule is that, in an equation, the expressions on each side of the equal sign must have the same dimensions. This is fairly intuitive since we can only add or subtract quantities of the same type (dimension). The second rule states that, in an equation, the arguments of any of the...

In mechanical engineering, a three-dimensional force system is a system of forces acting in three dimensions, with forces applied along the x, y, and z coordinate axes. The three-dimensional force system is an important concept in mechanical engineering, as it allows engineers to understand and analyze the behavior of objects and structures in three dimensions. By understanding the forces acting on a system, engineers can design more efficient and effective mechanical systems that can withstand...
