The evolution of bonding in orthodontics

Area of Science:

• Dentistry
• Orthodontics
• Biomaterials

Background:

• Early fixed-appliance orthodontic treatment utilized bands cemented to teeth, requiring significant chair time and causing patient discomfort.
• Banded appliances were associated with complications such as gingival trauma and enamel decalcification.

Observation:

• The mid-1960s marked a pivotal shift with the pioneering work of Dr. George Newman and Professor Fujio Miura in direct bonding of orthodontic brackets to enamel.
• This innovation aimed to overcome the limitations and patient discomfort associated with traditional banding techniques.

Findings:

• Subsequent decades witnessed continuous advancements in orthodontic bonding materials and techniques.
• Key developments include novel adhesives, improved bracket base designs, advanced bracket materials, efficient curing methods, self-etching primers, and the incorporation of fluoride-releasing agents and sealants.

Implications:

• Direct bonding significantly improved patient comfort and reduced treatment time compared to banded appliances.
• The evolution of bonding materials has enhanced treatment efficiency, durability, and esthetics in modern orthodontics.
• Ongoing research in biomaterials continues to refine bonding agents and bracket systems for optimal clinical performance.
