A New Orthodontic Appliance with a Mini Screw for Upper Molar Distalization.

Area of Science:

• Orthodontics
• Biomaterials Engineering
• Dental Mechanics

Background:

• Upper molar distalization is crucial for correcting Class II malocclusions.
• Traditional methods often require complex mechanics or patient compliance.
• Intraoral devices supported by orthodontic mini-screws offer a stable anchorage solution.

Purpose of the Study:

• To introduce and evaluate a novel intraoral appliance, the Cise distalizer.
• To assess the force delivery capabilities of the Cise distalizer for upper permanent molar distalization.
• To determine the optimal force level for molar movement using this new device.

Main Methods:

• The Cise distalizer, an intraoral device, was designed with eight primary components.
• Orthodontic mini-screws provide anchorage for the appliance.
• Strain gauge measurement techniques were employed to test the appliance under static loading conditions.

Main Results:

• Strain gauge analysis indicated that individual open coils generated approximately 300gr of distalization force.
• The Cise distalizer system is capable of delivering a total distalization force of 600gr.
• This force range is considered adequate for the distal movement of upper first and second molars.

Conclusions:

• The Cise distalizer is a novel intraoral appliance designed for effective upper permanent molar distalization.
• The appliance, supported by mini-screws, provides a controlled force system.
• The tested force levels are sufficient for achieving the desired molar distalization in orthodontic treatment.
