Cephalometric Assessment and Long-Term Stability of Anterior Open-Bite Correction with Skeletal Anchorage: A Systematic Review and Meta-Analysis

Year: 2025

Type: review

Study designs: Systematic Review, Meta-Analysis

Abstract: This systematic review evaluated the dento-skeletal effects and long-term stability of anterior open-bite (AOB) correction with temporary anchorage devices (TADs). A comprehensive search up to May 2025 was conducted in PubMed, Scopus, Web of Science, Embase, Cochrane Library, LILACS, Scielo, Epistemonikos, Google Scholar, and ScienceDirect. Eligible studies included randomized and non-randomized trials and case series with cephalometric outcomes. Risk of bias was assessed with the MINORS tool. A qualitative synthesis was performed, and studies meeting criteria were included in the meta-analysis. Ot of 1885 records, 22 studies were included qualitatively; 5 entered meta-analysis. Treatment yielded a mean overbite increase of 5.6 mm and reduction in N-Me of 2.8 mm. FMA and SN-GoMe decreased by about 2° and 1.6°, ANB by 1.7°, while SN-Pog increased by 1.4°. Most studies reported stability up to 3 years. Despite heterogeneity and predominance of non-randomized studies, evidence suggests TADs effectively correct AOB through overbite improvement and mandibular counterclockwise rotation. Reported effects appear stable, supporting skeletal anchorage as a reliable, less invasive alternative to surgery in selected patients.
