[Orthodontic repositioning technic of impacted lower 2nd molars]

Area of Science:

• Orthodontics
• Dental Mechanics

Background:

• Horizontal impaction of mandibular second molars presents a significant clinical challenge.
• Traditional treatment often requires surgical intervention, increasing patient morbidity.

Purpose of the Study:

• To present a novel orthodontic appliance for the non-surgical uprighting of horizontally impacted mandibular second molars.
• To describe the mechanism of action of the appliance.

Main Methods:

• The appliance utilizes a Mollin lower lingual arch for mandibular anchorage.
• An auxiliary spring is incorporated to facilitate tooth movement.
• The spring engages the impacted molar in a two-step process: initial distal movement, followed by crown tipping.

Main Results:

• The described appliance enables the uprighting of impacted mandibular second molars.
• The treatment approach is exclusively orthodontic, eliminating the need for surgical procedures.
• The appliance facilitates controlled tooth movement in two distinct phases.

Conclusions:

• A new orthodontic appliance offers a viable non-surgical solution for impacted mandibular second molars.
• This appliance simplifies treatment by combining anchorage and active uprighting components.
• The described method provides a significant benefit by avoiding surgical complications.
