[Long-term stability and relapse of deep bite correction: a systematic review].

Area of Science:

• Orthodontics and Dental Malocclusions
• Maxillofacial Surgery
• Biomedical Engineering

Background:

• Deep overbite is a prevalent and challenging malocclusion, with long-term stability of correction being a significant clinical concern.
• Existing systematic reviews are outdated, necessitating an updated analysis due to recent treatment advancements and publications on relapse prevention.
• Understanding factors influencing deep overbite correction stability is crucial for successful orthodontic outcomes.

Purpose of the Study:

• To conduct a systematic review evaluating the long-term stability of deep overbite correction.
• To identify key factors, such as treatment technique and patient age, that influence relapse rates.
• To provide evidence-based insights for optimizing deep overbite treatment strategies.

Main Methods:

• Comprehensive search of electronic and nonelectronic databases for relevant studies on deep overbite relapse.
• Systematic analysis and data extraction from selected articles.
• Assessment of the scientific quality of included studies.

Main Results:

• An overall deep overbite relapse rate of 47.27% was observed.
• Treatment with the Ricketts appliance showed a lower relapse rate (30.38%) compared to the straight wire appliance (67.74%).
• Treatment initiated in late adolescence (14.3% relapse) yielded greater stability than early teen or adult treatment (approx. 30% relapse); Botox injections in surgery achieved 100% stability.

Conclusions:

• Patient age at the initiation of treatment is a critical determinant of long-term deep overbite correction stability.
• The chosen orthodontic treatment technique significantly impacts the likelihood of relapse.
• Further research into novel techniques, like Botox-assisted surgery, may offer improved stability.
