Mechanical Systems

Mechanical Systems

Mechanical systems are analogous to to electrical networks where springs and masses play similar roles to inductors and capacitors, respectively. A viscous damper in mechanical systems functions similarly to a resistor in electrical networks, dissipating energy. The forces acting on a mass in such systems include an applied force in the direction of motion, counteracted by forces from the spring, a viscous damper, and the mass's acceleration. This interplay of forces is mathematically described...

Electro-mechanical Systems

Electro-mechanical Systems

Electromechanical systems are intricate configurations that effectively combine electrical and mechanical elements to achieve a desired outcome. Central to many of these systems is the DC motor, a device that converts electrical energy into mechanical motion, enabling various applications ranging from simple fans to complex robotic mechanisms.
A key component of the DC motor is the armature, a rotating circuit positioned within a magnetic field. As an electric current passes through the...

Area of Science:

Biomedical Engineering
Dental Technology
Robotics in Medicine

Background:

Prolonged dental work leads to fatigue and hand tremors, compromising rotatory instrument handling and causing oral injuries.
Current dental practices lack systems to support dentists in managing dental drills.
A mechatronic system is proposed to aid dentists in handling dental drills.

Purpose of the Study:

To develop and evaluate a mechatronic system for assisting dentists with dental drill handling.
To assess the system's impact on positioning accuracy, resolution, and user adaptation.

Main Methods:

A mechatronic system with an articulated arm, force sensors, and electronic actuators was designed.
The system holds the dental handpiece, supporting it alongside the dentist's hand.
Expert dentists and students performed tasks like drawing circles and preparing cavities to evaluate accuracy and resolution.

Main Results:

The mechatronic system enhanced positioning accuracy by 53% (p < 0.017).
Drilling resolution improved by 76% (p < 0.001) with the system.
The system provided stability, preventing involuntary movements and improving work quality.

Conclusions:

The first mechatronic system to assist dentists in handling dental drills has been developed.
The system enables smooth, precise manipulation of dental tools, reducing tremor from fatigue.
This technology minimizes the risk of iatrogenic dental injuries during cavity preparation.
