An Approach with Hybrid Segmental Mechanics

Area of Science:

• Orthodontics
• Biomaterials Engineering

Background:

• Continuous arch wire mechanics can lead to undesirable side effects.
• Hybrid segmental mechanics offer a versatile alternative for complex orthodontic cases.

Observation:

• A 13-year-old male presented with skeletal class I, anterior crossbite, significant crowding (12mm upper, 5mm lower), and proclined anteriors.
• Treatment involved segmental canine retraction using Titanium Molybdenum Aluminum (TMA) 'T' loop springs, followed by space consolidation with continuous arch mechanics.

Findings:

• The hybrid approach successfully achieved treatment objectives, yielding favorable intraoral and facial results.
• The use of traditional twin brackets facilitated the integration of continuous, segmental, and hybrid sectional mechanics.

Implications:

• Hybrid segmental mechanics provide an effective treatment strategy, mitigating side effects associated with solely continuous arch wire mechanics.
• This versatile approach enhances orthodontic treatment outcomes and patient satisfaction.
