Long-term Stability of Anterior Open bite Correction: a Systematic Review

Abstract

Background: Anterior open bite is one of the malocclusions the most commonand the most difficult to treat successfully. The real challenge remains the stability of this correction over time. Evidence based dentistry related the long-term stability of the correction of open bite are limited. The evidence based on the long-term stability of open bite correction is to be searched in systematic reviews. The purpose of thissystematic reviewwas to evaluate the long-term stability of anterior open correction.
Methods: Electronic databases were searched and nonelectronic journals were hand searched on the long-term stability of anterior open bitecorrection. The appropriate papers for an inclusion in this review were found and analyzed. Their scientific quality was estimated and the data which they contain extracted and summarized.
Results: The electronic and hand searches retrieved 598 unique citations but 29 articles were eligible for evaluating their quality and data extraction. More than half of the studies had a high risk of bias(58.62%); when 13.79% were low risk and 27.59 % a moderate risk of bias.The combination of orthognathic surgery associated with orthodontic treatment was the most commonly used involving 600 patients. The rate of open bite relapse was 31.28 %.
Conclusion: Taking into account the limitations of the study design and the quality of the papers included in this review, anterior open bite correction are not stable one year after treatment in about one third of the patients. Key words: Systematic review;open bite;Stability;Relapse.
