Dentistry exposes professionals to multiple risk factors: forced neck and back postures when leaning over the patient, exposure to aerosols and blood, needle sticks, mercury from amalgams, constant turbine noise, and latex dermatitis. Analyzing these hazards through three-dimensional simulations allows for more precise and effective prevention in the clinical environment.
Biomechanical simulation and 3D fluid dynamics 🦷
Using 3D biomechanics software, it is possible to model the forced postures of the dentist during prolonged procedures, visualizing the load on cervical and lumbar vertebrae to redesign the ergonomics of the chair and the operator's position. Additionally, computational fluid dynamics allows recreating the dispersion of contaminated aerosols in the office, identifying areas of higher concentration and evaluating the effectiveness of physical barriers or ventilation systems. The modeling also serves to simulate the trajectories of rotary instruments and needles, optimizing safety protocols.
Towards safer dentistry with additive prototyping 🖨️
3D printing enables the design and manufacture of customized face shields, ergonomic handles for instruments, and anti-splash covers adapted to each piece of equipment. Combining virtual simulation with physical prototypes reduces testing times and validates solutions before real-world implementation. This approach integrates occupational health with technological innovation, offering concrete tools to minimize chronic and acute risks for the dentist.
