Incisor extrusion with or without molar intrusion for the correction of anterior open bite with clear aligners and comparison of outcomes with fixed appliances incorporating temporary anchorage devices: A systematic review and meta-analysis

Key Points

• This research aims to compare the effectiveness of incisor extrusion and molar intrusion in correcting anterior open bite using different orthodontic devices.
• Conducted a systematic review and meta-analysis
• Compared outcomes of clear aligners and fixed appliances
• Evaluated the role of temporary anchorage devices in treatment
• Incisor extrusion effectively increases overbite, but not as much as molar intrusion
• Molar intrusion shows superior effectiveness for open bite correction with fixed appliances
• Teeth vertical position remained stable during retention period
