A Methodological Approach for Motor Selection in Dental Impression Material Dispensers Using Experimental and Image...

Area of Science:

• Biomaterials Engineering
• Mechanical Engineering
• Dental Technology

Background:

• Electric dispensers for dental impression materials are often overdesigned, leading to inefficiency.
• Optimizing drive motor capacity is crucial for improving dispenser performance and reducing energy consumption.

Purpose of the Study:

• To develop a methodology for preventing overdesign in electric dental impression material dispensers.
• To systematically determine appropriate drive motor capacity based on extrusion load and pressurization speed.

Main Methods:

• Derived an equation for motor torque and rotational speed based on extrusion load and material speed.
• Developed a specialized load measurement system to quantify extrusion forces.
• Utilized image processing, position coordinate plotting, curve fitting, and circle fitting to determine optimal pressurization speed.

Main Results:

• Established a correlation between impression material's curvature radius and pressurization speed.
• Significantly reduced required motor torque and rotational speed compared to current standards.
• Demonstrated a systematic approach to sizing drive motors for dental dispensers.

Conclusions:

• The proposed methodology effectively prevents overdesign in electric dental impression material dispensers.
• Optimized motor sizing leads to reduced power consumption, weight, and size.
• This research contributes to the development of more efficient and compact dental devices.
