Fixed orthodontic appliances excel in complex cases, offering precision and reduced relapse. Transparent aligners provide superior aesthetics and hygiene, though they may impact mandibular bone density.
Area of Science:
- Orthodontics
- Biomaterials Science
Context:
- Patient demand for faster, aesthetically pleasing orthodontic treatments is increasing.
- Choosing between fixed appliances and clear aligners presents a significant clinical challenge.
Purpose:
- To compare the advantages and disadvantages of fixed orthodontic appliances versus transparent aligners.
- To provide evidence-based insights for selecting the optimal orthodontic treatment modality.
Summary:
- A systematic literature review of 53 articles (1991-2023) from PubMed, SciElo, and Web of Science compared fixed braces and clear aligners.
- Fixed appliances demonstrate higher precision and efficacy in complex malocclusions, with lower relapse rates.
- Transparent aligners offer enhanced aesthetics and hygiene but are associated with decreased mandibular condyle bone density.
Impact:
- Informs clinical decision-making for orthodontists regarding appliance selection based on case complexity and patient priorities.
- Highlights the trade-offs between treatment efficiency, aesthetics, and potential biological effects of different orthodontic systems.
