What was done
The authors conducted a literature review analyzing the role of interproximal reduction (IPR) in clear aligner therapy. The review evaluates indications, clinical techniques, therapeutic outcomes (space gaining, tooth size discrepancy management, tooth re-shaping, and aesthetics), and potential biological complications (pulp temperature rise, enamel surface roughness, cavity risk, soft tissue effects, and post-treatment sensitivity).
What was found
The abstract reports no numerical findings, statistical metrics, or specific study counts, providing only a general conceptual overview of the literature.
Why it matters
Because interproximal reduction is an irreversible step integrated into digital aligner workflows, understanding both its mechanical benefits and potential biological risks is critical for safe orthodontic planning.
Limits
This is a narrative review with no systematic search criteria, meta-analysis, or new primary data reported. The abstract provides no quantitative data on complication rates, efficacy, or sample sizes.
