Area of Science:

  • Orthodontics
  • Biomaterials Science

Background:

  • Clear aligners are gaining popularity for treating complex malocclusions.
  • Limited data exists comparing their efficacy against fixed appliances in difficult cases.

Purpose of the Study:

  • To compare occlusal outcomes, treatment efficiency, and patient experience between clear aligners and fixed appliances in complex orthodontic cases.
  • To evaluate Peer Assessment Rating (PAR) score changes, treatment duration, appointment frequency, refinement needs, and oral health-related quality of life (OHIP-14).

Main Methods:

  • Prospective comparative study design.
  • Random assignment of complex orthodontic cases to either clear aligner therapy or conventional fixed appliances.
  • Assessment of clinical outcomes and patient-reported measures.

Main Results:

  • Both treatment modalities resulted in clinically significant occlusal corrections.
  • Fixed appliances demonstrated superior efficiency in complex biomechanics, particularly with extractions.
  • Clear aligners provided enhanced initial patient comfort and improved oral health-related quality of life.

Conclusions:

  • Clear aligners can be effective for complex cases with careful biomechanical planning and high patient compliance.
  • Fixed appliances remain advantageous for complex root control and extraction space closure due to efficiency benefits.
