Summary
Invisalign and traditional braces show similar orthodontic tooth movement (OTM) efficacy. However, Invisalign treatment is significantly faster than fixed appliances, offering a more efficient orthodontic solution.
Area of Science:
- Orthodontics and Dental Technology
- Biomedical Engineering
- Clinical Dentistry
Background:
- Existing literature lacks direct comparisons of Invisalign and fixed appliance efficacy for orthodontic tooth movement (OTM).
- A need exists to empirically compare the amount and rate of OTM between these two prevalent orthodontic modalities.
- Informed treatment decisions require clear, evidence-based comparisons of Invisalign versus traditional fixed appliances.
Purpose of the Study:
- To evaluate and compare the efficacy of Invisalign and fixed orthodontic appliances in terms of OTM.
- To determine statistically significant differences in achieving OTM between Invisalign and fixed appliances.
- To assess differences in treatment duration between Invisalign and traditional fixed appliances.
Main Methods:
- Systematic review and meta-analysis of eligible studies identified through targeted database searches.
- Utilized MeSH keywords and Boolean operators for comprehensive literature retrieval.
- Included 10 studies in the pooled analysis based on predefined eligibility criteria.
Main Results:
- A statistically significant reduction in treatment time was observed with Invisalign compared to fixed appliances (OR = 0.61, p=0.004).
- No significant heterogeneity was detected among the included studies (I² = 0%).
- A non-significant trend favored Invisalign in terms of OTM efficacy (OR = 1.43, p=0.07), with negligible heterogeneity (I² = 0%).
Conclusions:
- Invisalign and fixed orthodontic appliances demonstrate comparable overall efficacy in achieving orthodontic tooth movement.
- Invisalign treatment is associated with a significantly shorter treatment duration compared to fixed appliances.
- Further research is warranted to investigate the long-term stability of orthodontic outcomes with both treatment modalities.
