[Fixed appliances current state of the art]

Area of Science:

• Orthodontics and Dental Technology
• Biomaterials Science

Background:

• Fixed orthodontic appliances have seen significant evolution.
• Patient demand for improved aesthetics and treatment efficiency drives innovation.

Purpose of the Study:

• To review and discuss recent advancements in fixed orthodontic appliances.
• To highlight new materials, biomechanical strategies, and finishing protocols.

Main Methods:

• Review of current literature and clinical practices.

• Exploration of advanced biomechanical calculations and orthodontic finishing techniques.

Main Results:

• Introduction of cosmetically superior brackets and advanced alloy archwires.
• Application of precise force and torque computations for enhanced biomechanics.
• Integration of concepts like Andrews'
• six keys to normal occlusion
• and gnathological principles for treatment finish.

Conclusions:

• Modern fixed appliances offer enhanced esthetics and biomechanical control.
• New materials and techniques contribute to more predictable and efficient orthodontic outcomes.
• Focus on precise bracket positioning and occlusion refinement improves treatment results.
