Summary
This summary is machine-generated.

True incisor intrusion is achievable using the segmented arch technique, yielding approximately 1.5 mm in the maxilla and 1.9 mm in the mandible. However, its clinical significance for severe deep bites remains uncertain.

Area of Science:

  • Orthodontics and Dental Research
  • Biomedical Engineering
  • Evidence-Based Dentistry

Background:

  • This systematic review and meta-analysis investigates the efficacy of orthodontic intrusion of permanent incisors.
  • Focuses on clinical trials utilizing cephalometric radiography for precise measurement of incisor movement.

Discussion:

  • A meta-analysis of two studies using the segmented arch technique revealed mean incisor intrusion of 1.46 mm (maxillary) and 1.90 mm (mandibular).
  • Methodological limitations in initial screening led to the exclusion of 24 out of 28 articles.
  • The segmented arch technique demonstrates quantifiable incisor intrusion in non-growing patients.

Key Insights:

  • True incisor intrusion is clinically achievable in both maxillary and mandibular arches.

  • The segmented arch technique facilitates an average intrusion of 1.5 mm (maxillary) and 1.9 mm (mandibular).
  • The clinical impact of this magnitude of intrusion as a standalone treatment for severe deep bites requires further consideration.

    • Outlook:

    • Further research is needed to establish the long-term stability and functional outcomes of true incisor intrusion.
    • Investigating alternative or adjunctive treatment modalities for severe deep bite cases is warranted.
    • Refining methodologies for cephalometric analysis in orthodontic research will enhance future systematic reviews.
